The purpose of the surveys was to document vegetation communities and sensitive biological resources which could be impacted by future development within the study area. The current survey work was evaluated in conjunction with past biological investigations of the properties. The study area encompasses approximately 650 acres located east of El Camino Real and north of Palomar Airport Road, south of the Los Monos preserve, and west of the City of Vista. The study area consists of mostly mild slopes supporting sage scrub or chaparral vegetation, and drainages supporting mature canopies dominated by Coast Live Oak (Quercus agrifolid), Western Sycamore (Platanus racemosa), and several species of willow (Salix spp.). Sensitive plants identified on-site include an abundance of NuttalFs Scrub Oak (Quercus dumosd) and California Adolphia (Adolphia californicd), moderate numbers of Summer-Holly (Comarostaphylis diversifolia) and Southwestern Spiny Rush (Juncus acutus), and five small patches of the federally threatened San Diego Thorn-mint (Acanthomintha ilicifolia). A previous investigation identified numerous federally endangered Del Mar Manzanita (Arctostaphylos glandulosa ssp. crassifolia) on the west side of the study area. However, the current survey work determined these plants to be the similar but non-sensitive Eastwood Manzanita (Arctostaphylos glandulosa ssp. zacaensis). Sensitive animal species present include four territories of the federally threatened Coastal California Gnatcatcher (Polioptila californica californicd). Other sensitive wildlife species commonly found in the on-site sage scrub and/or chaparral habitats were the San Diego Horned Lizard (Phrynosoma coronatum blainvillii), Orangethroat Whiptail (Cnemidophorus hyperythrus), and Southern California Rufous-crowned Sparrow (Aimophila rujiceps canescens). Highly noteworthy is the presence of a breeding pair of Northern Harriers (Circus cyaneus), which fledged two young on the site this past spring. The White-tailed Kite (Elanus leucurus) and Red-shouldered Hawk (Buteo lineatus) were confirmed nesting on-site, and the Cooper's Hawk (Accipiter cooperii) is expected to nest on-site based upon repeated observations of individuals in highly suitable habitat. The Burrowing Owl {Athene cunicularid) was reported on-site in the mid-1980s; however, there are no recent records or sign of its presence. Also, the Golden Eagle (Aquila chrysaetos) was reported on-site in the mid-1980s, but no recent sightings have been made, and based on the large distance to the nearest known nesting locality and the intervening urbanization, the site is not expected to be a significant use area for Golden Eagles. The study area occupies the southern half of Core #5 of the City of Carlsbad's Habitat Management Plan Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 1 Merkel & Associates, Inc. # 97-104-06 December I, 2000 (HMP). It connects via an extended, generally narrow and circuitous linkage (Link D) to Core #6. Core #5 also connects to Core #3 through Link C. Important with respect to the HMP is that regional wildlife corridors are identified passing through the property. These include the main riparian corridor of Agua Hedionda Creek (northwest/north-central part of study area) and the un-named drainage passing from east to west in the south-central part of the study area. This latter corridor is particularly important as it connects to Link D (through the Carlsbad Raceway property), which provides the more eastern of only two linkages connecting the northern and southern sections of the Carlsbad HMP. This report does not evaluate potential biological impacts, nor does it provide recommendations to reduce or mitigate such impacts. INTRODUCTION Biological surveys of the proposed Faraday Avenue extension and the Agua Hedionda Truck Sewer extension, as well as the Carlsbad Oaks North Business Park project site, were performed at the request of Kimley-Horn and Associates for the City of Carlsbad. The purpose of the investigations was to summarize the vegetation communities present on-site and to identify endangered, threatened, or otherwise sensitive plant and animal species occurring within the identified study area. This information is intended to guide an assessment of expected biological impacts associated with implementation of the component projects. LOCATION The study area is located in unsectioned lands of Township 11 South, Range 4 West of the San Bernardino Base & Meridian, USGS 7.5' San Luis Rey Quadrangle (Figure 1). The project site lies in the City of Carlsbad in northwestern San Diego County. Access to the southwest corner of the study area is via an unnamed dirt road adjacent to El Camino Real, which crosses all the way to the eastern border of the study area. Alternatively, the eastern portions of the site are accessible from the termination of Faraday Avenue, at the western limit of the City of Vista. The northwestern portion of the study area is accessed from Sunny Creek Road, which also exits off of El Camino Real. METHODS Biological and wetlands investigations were conducted according to the times and conditions listed in Table 1. The present study benefits significantly from a number other efforts performed on various portions of the current study area. Previous biological work has been performed for the Carlsbad Oaks North Business Park site (Dudek 1997, Recon 1984), the Faraday Avenue extension (Dudek 1999a), and for a segment of the sewer extension (Dudek 1999b). An area encompassing much of the more southerly portions of the study area was surveyed by Merkel & Associates in 1997 (M&A 1997). Also, the western portion of the study area was investigated by KEA Environmental for its suitability as a County of San Diego mitigation site (KEA 1998). Where biological information required updating, or where there is a difference of professional opinion as to the categorization of a particular vegetation assemblage, these changes have been made and discussion is provided in the Vegetation section of this report. A list of all vascular plant species identified on-site is provided in Appendix 1. Appendix 2 lists all vertebrate and butterfly species detected in the study area. Sensitive plant and animal species known or with potential for on-site occurrence are reviewed within this report; Appendix 3 provides a summary of sensitivity guidelines and definitions for these sensitive species.

Jassal BOTANICAL INVESTIGATIONS Vegetation communities and sensitive resources were plotted on 1" = 200' topographic base maps and digitized into an AutoCAD format by Kimley-Horn and Associates, Inc. Previous vegetation mapping performed by Dudek and Associates was used as a baseline for the work. All plant communities, soil types, and slope exposures were surveyed on-foot. Plant identifications were either resolved in the field or later determined through verification of voucher specimens. Vegetation communities were generally delineated according to Holland (1986) as modified by Oberbauer (1993). Delineation of some on-site vegetation communities was particularly difficult due to the co-existence of key indicator species. For example, the sensitive NuttalPs Scrub Oak (Quercus dumosd) is an important indicator species for Southern Maritime Chaparral, while the similar Interior Scrub Oak (Quercus berberidifolid) is characteristic of Southern Mixed Chaparral. Often these plants were found in close association; more confusing is that many individual plants showed hybrid traits for both species. Where Nuttall's Scrub Oak provided the clear majority of the shrub cover, the habitat was delineated as Southern maritime chaparral/Nuttall's scrub oak phase, a sensitive vegetation type. Delineation between sage scrub and chaparral vegetation was also difficult in some areas due to the dominance of species which readily occur in either of these two plant communities, such as Black Sage (Salvia mellifera) and Toyon (Heteromeles arbutifolid). The presence and predominance of Chamise, Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Mission Manzanita (Xylococcus bicolor), Interior Scrub Oak, NuttalPs Scrub Oak, or Ramona Ceanothus (Ceanothus tomentosus) were used to distinguish chaparral (i.e., Southern Mixed Chaparral) areas from sage scrub (Coastal Sage Scrub). Primary Coastal Sage Scrub indicators were California Sagebrush (Artemisia californicd), Flat-top Buckwheat (Eriogonum fasciculatum), and White Sage (Salvia apiand). Secondary indicators used to define sage scrub vegetation included California Adolphia (Adolphia californicd). In a very few areas there was a mix of indicator species for both sage scrub and chaparral. These areas were delineated as Coastal Sage/Chaparral Scrub to indicate the ecotone condition. Substantial areas formerly mapped as chaparral in prior studies are now clearly dominated by sage scrub components, though occasional Chamise or Mission Manzanita occur as isolated elements. Such areas are mapped as Coastal Sage Scrub as they clearly retain a greater than 90% sage scrub cover. ZOOLOGICAL INVESTIGATIONS Presence of wildlife species was determined primarily through direct observation (aided by binoculars). Identification of songs, call notes or alarm calls, as well as observation of indirect sign (burrows, tracks, scat, etc.) were used to confirm the presence of various wildlife species. Appendix 2 provides a list of the wildlife species identified on-site. Focused investigations were performed according to U.S. Fish and Wildlife Service (USFWS) protocols for two federally listed species, the Coastal California Gnatcatcher (Polioptila californica californicd) and the Least Bell's Vireo (Vireo belliipusillus). In addition, during the surveys for the Least Bell's Vireo, special attention was paid to the potential presence of the Southwestern Willow Flycatcher (Empidonax traillii extimus), and taped recordings were played to elicit response from any potentially occurring Willow Flycatchers. California Gnatcatcher Surveys Three or more visits were performed in areas under time and weather conditions suitable for gnatcatcher activity. Taped recordings of the gnatcatcher's distinctive vocalization were played approximately every 200 feet of survey distance in suitable habitat. Up to several minutes were allowed for a response, especially from advantageous viewpoints. Least Bell's Vireo Surveys The 2000 surveys performed by Merkel & Associates were targeted to determine the presence of highly sensitive species, specifically the Least Bell's Vireo and the Southwestern Willow Flycatcher. Surveys for these two species generally followed current protocol of the U.S. Fish and Wildlife Service (USFWS 1999a and Sogge et al 1997, respectively), except that tape recordings of the Willow Flycatcher were played by authorized personnel on most visits in an effort to maximize potential detection of this species. Although these species were the focus, all vertebrate species observed were recorded. WETLAND DELINEATION AND JURISDICTIONAL WATERWAY DETERMINATION M&A biologists Kyle L. Ince, Vanessa A. Lee, and Navroop K. Jassal, and Kimley Horn & Associates' biologist Karina Perovich, conducted wetland delineation work in July and August of 2000. Delineations of the site were performed using the routine on-site determination methods noted in the 1987 Army Corps of Engineers' (ACOE) Wetland Delineation Manual (ACOE 1987). In addition, the delineation effort was expanded to identify Non-wetland Waters of the United States under federal jurisdiction and streambeds under the jurisdiction of the California Department of Fish and Game Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 6 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 (CDFG). Wetlands and jurisdictional waterways were plotted on a 1" = 200' topographic map of the project site as well as a 1" = 400' aerial photograph of the project site. Streambed widths were noted on the map to provide true jurisdictional dimensions. Evidence supporting jurisdictional determinations was recorded on wetland field data forms and depicted in photographs of the project site (Appendix 4 and 5, respectively). The following text describes the three parameters used to determine the presence/absence of wetlands and non-wetland water streambeds occurring on the project site. Additional information on the overall delineation process and regulatory jurisdictions may be found in the federal delineation manual (ACOE 1987), state and federal .enacting legislation, or through guidance provided by judicial interpretation, solicitors' opinions, and regulatory guidance issued to ACOE offices and CDFG field staff. Wetland Vegetation Vegetation communities which met the criteria of wetland-associated vegetation were dominated by a preponderance of species classified as obligate wetland plants (OBL), facultative wetland plants (FACW), or facultative plants (FAC) based on the National List of Plant Species that Occur in Wetlands (U.S. Fish and Wildlife Service 1988). Areas indicated as Non-wetland Waters of the U.S. typically lacked vegetation or were dominated by upland species, but exhibited wetland hydrologic characteristics. Wetland Hydrology Hydrologic wetland indicators included both surficial and sub-surficial characteristics. Most of the flow information consisted of drainage patterns. Additional flow evidence included soil saturation or inundation, oxidized root channels, drift lines, and sediment deposits. Furthermore, hydrologic indicators were used to define Non-wetland Waters of the U.S. Wetland Soils To confirm the presence of hydric soils, soil test pits were excavated using a shovel. Soils taken from depths ranging from 12 to 16 inches were examined for physical and chemical evidence of hydric conditions. However, due to the abundance of cobble in the soils at this particular site, soil test pits were often limited to much shallower depths. Excavated soils were evaluated using the chroma index from the Munsell Soil Color Charts (Munsell Color 1974), but soil color was not used as the only indicator in the study area's mineral sandy soils. Additional indicators of hydric soils such as vertical streaking, high organic matter content in the surface horizon, mottling, and sulfidic odor were evaluated during the delineation. Wetlands and jurisdictional waters existing on the project site are regulated by one or both of the following: Section 404 of the Clean Water Act regarding discharge of dredged or fill materials into the waters of the United States; and, Sections 1600 et seq. of the California Fish & Game Code which regulates modifications to streambeds. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Jurisdiction U.S. Army Corps of Engineers Under section 404 of the Clean Water Act, the ACOE has regulatory authority over the discharge of dredged or fill materials into the waters of the United States (1344 USC). The term "waters of the United States" is defined in 33 CFR Part 328 and includes: (1) all navigable waters (including all waters subject to the ebb and flow of the tide); (2) all interstate waters and wetlands; (3) all other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce; (4) all impoundments of water mentioned above; (5) all tributaries to waters mentioned above; (6) the territorial seas; and, (7) all wetlands adjacent to waters mentioned above. In the absence of wetlands, the limits of ACOE jurisdiction in non-tidal waters, such as intermittent streams, extend to the ordinary high water mark (OHWM) which is defined at 33 CFR 328.3(e) as: ... that line on the shore established by the fluctuation of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas. Wetlands are defined at 33 CFR 328.3(b) as "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support ... a prevalence of vegetation typically adapted for life in saturated soil conditions." California Department of Fish and Game CDFG regulates alterations of "streambeds" through the development of a Streambed Alteration Agreement pursuant to Division 2, Chapter 6, sections 1600-1603 of the Fish and Game Code. An Agreement is required whenever a project would "divert, obstruct or change the natural flow or bed, channel or bank of any river, stream or lake designated by the Department." The breadth of areas subject to regulation by CDFG under section 1600 are less clearly defined than those regulated by ACOE; however, in general, the policies are fairly consistent. It is clear that all "rivers, streams, lakes and streambeds which may exhibit intermittent flows of water" are covered by the California statutes. Section 1600 et seq. does not extend to isolated wetlands and waters such as small ponds not located on a drainage course, wet meadows, vernal pools, or tenajas as does federal jurisdiction. Furthermore, CDFG jurisdiction does not extend over tidal waters. However, section 1600 et seq. jurisdiction extends over all riparian habitat supported by a river, stream, or lake regardless of the riparian area's federal wetland status. Unlike the ACOE process, the Streambed Alteration Agreement is not a discretionary permit, but rather an Agreement developed between an applicant and CDFG with specified avoidance measures, impact reduction, or mitigation. These measures are subject to acceptance by the applicant. If an Agreement cannot be reached between CDFG and the applicant, a formal arbitration process is available. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park Merkel & Associates, Inc. # 97-104-06 December 1, 2000 SCIENTIFIC NOMENCLATURE The scientific nomenclature used in this report is from the following standard references: vegetation and wildlife habitat, Holland (1986) and Oberbauer (1993); flora, Skinner and Pavlik (CNPS) (1994), Hickman (1993), or Beauchamp (1986); butterflies, Opler (1999) or Garth and Tilden (1986); amphibians and reptiles, Collins (1990); birds, American Ornithologists' Union (1983, Seventh Edition); and mammals, Jameson and Peeters (1988) and Hall (1981). GENERAL PHYSIOGRAPHY The varied topography of the site includes a canyon area, a complex exposure of slopes, and a major drainage that bisects the property. A number of tributary runnels provide watershed drainage for this creek; however, they are generally arid most of the year. A low elevation of 125 feet (MSL) occurs within the creek, in its northwestern portion. A high elevation of 535 feet (MSL) occurs in the northeast section of the property. Surrounding land uses include urban/industrial development to the south and west, with residential development bordering the study area to the east. Undeveloped, preserved native vegetation occurs to the north, with a mix of agricultural fields and fragmented native habitats to the northwest. Due to the nearby housing and businesses, the site receives moderate to high amounts of use by mountain bikers and hikers, and domestic pets were often seen running free in the northeast corner of the study area. Considerable use by illegal immigrants was noted within Agua Hedionda Creek, at the northwest side of the study area (adjacent to the agricultural fields). Within the oak woodlands elsewhere on the property, historic and recent evidence of small homeless encampments was observed. Underlying geology for the site is mapped as Mesozoic granitic rocks in the north, and Eocene marine deposits in the south (Rogers 1973). A number of soil types are reported from the study area. These include Altamont Clay, Cieneba coarse sandy loam, Cieneba rocky coarse sandy loam, Cieneba- Fallbrook rocky sandy loam, Fallbrook sandy loam, Gaviota fine sandy loam, Huerhuero loam, Las Flores loamy fine sand, Salinas clay loam, Tujunga sand, Visalia sandy loam, Vista coarse sandy loam, riverwash, and terrace escarpments (Bowman 1973). The clay soils found on-site are of special concern as they potentially support a number of sensitive plant species. For example, Thread-leaved Brodiaea (Brodiaea filifolid) was found in the area mapped as Salinas clay loam, and localized pockets within Altamont Clay supported San Diego Thorn-mint (Acanthomintha ilicifolid). BIOLOGICAL RESOURCES Vegetation, wetlands, and sensitive species are shown in a graphic in the enclosed map pocket. VEGETATION Twenty-one vegetation communities were delineated in the study area (Figure 2, Table 2). Coastal Sage Scrub Coastal Sage Scrub in the study area is generally dominated by California Sagebrush (Artemisia californica); Flat-top Buckwheat (Eriogonumfasciculatum), and Laurel Sumac. Locally common shrubs included Black Sage, California Adolphia, Coyote Brush (Baccharispilularis), Lemonade-Berry, and Toydn. Overall, the habitat is moderately tall (5-6 feet in height) and dense; areas locally dominated by Laurel Sumac, Lemonade-Berry, or Toyon typically exceeded eight feet in height.

Oberbauer (1993) for San Diego County Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 11 Merkel & Associates, Inc. # 97-104-06 December I, 2000 Numerous wildlife species, including several considered sensitive by resource agencies, occur in the on- site Coastal Sage Scrub habitat. Typical resident species were the California Quail (Callipepla californicd), California Towhee (Pipilo crissalis), Bushtit (Psaltriparus minimus), and Wrentit (Chamaeafasciatd). Sensitive species observed in this habitat included the San Diego Horned Lizard (Phrynosoma coronatum blainvillii), Orangethroat Whiptail (Cnemidophorus hyperythms), California Gnatcatcher, and Southern California Rufous-crowned Sparrow (Aimophila ruficeps canescens). Coyote Brush Scrub Coyote Brush is the defining plant species of this sage scrub-like plant community. On-site it is generally found adjacent to drainages and where disturbance has precluded other native plant species. Other species within this habitat are small/moderate numbers of Decumbent Gold.enbush (Isocoma menziesii var. menziesii), Flat-top Buckwheat, California Sagebrush, and Poison Oak (Toxicodendron diversilobum). The understory contains seedlings of the previously mentioned shrubs, various weedy herbaceous species such as Western Ragweed (Ambrosia psilostachya), as well as both native (e.g., Nassella) and non-native grasses (e.g., Avena, Bromus). Wildlife observed in the Coyote Brush are generally the same as those mentioned for Coastal Sage Scrub. California Quail were often flushed from this habitat, and California Gnatcatchers were found foraging in Coyote Brush Scrub in both the center and far eastern portions of the study area. Southern Maritime Chaparral/Nuttall' Scrub Oak Phase Southern maritime chaparral/NuttalPs scrub oak phase is primarily identified in the southwestern and southern portions of the study area. It is usually defined by a dominance of Nuttall's Scrub Oak. Summer-Holly may be locally common, or occur as a scattered element. Other plant species found in varying amounts in the on-site Southern maritime chaparral/Nuttall's scrub oak phase include Chamise, Mission Manzanita, Toyon, Lemonade-Berry, and occasional Interior Scrub Oak. This habitat is typically 5-10 feet tall and relatively dense. Wildlife use of Southern maritime chaparral/Nuttall's scrub oak phase included many species commonly found in Coastal Sage Scrub, as well as species preferring a slightly dense or taller canopy. Wildlife noted in this habitat included the California Thrasher (Toxostoma redivivum), Spotted Towhee (Pipilo maculatus), Western Scrub-Jay (Aphelocoma californicd), Wrentit, Bewick's Wren (Thryomanes bewickii), and the relatively ubiquitous California Towhee. Southern Mixed Chaparral Southern Mixed Chaparral encompasses several on-site chaparral associations which vary due to relative abundance of component species, slope exposure, and possibly soil type. Characteristic plants in this habitat included Chamise (often dominant), Mission Manzanita, Toyon, Black Sage, and Interior Scrub Oak. Ramona Ceanothus, and Dark-tip Bird's-beak (Cordylanthus rigidus) are localized elements. Incursions of narrow patches of Flat-top Buckwheat, Laurel Sumac, and California Adolphia are sometimes isolated components. More gentle and south-facing slopes tend to be dominated by Chamise, while the north-facing slopes and habitat adjacent to the drainage at the west side of the study area tend to support Interior Scrub Oak. The variable shrub composition and density supported good wildlife diversity. Commonly observed in this habitat were California Towhee, California Quail, Western Scrub-Jay, Spotted Towhee, and Wrentit. Near rock outcrops, nests of the San Diego Desert Woodrat (Neotoma lepida intermedia) were observed, and both San Diego Horned Lizard and Orangethroat Whiptail were found along dirt trails within the Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 12 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 chaparral. California Sage - Chaparral Scrub This ecotonal community contains a high proportion of both sage scrub and chaparral indicator species, as well as plants that regularly occur in both scrub and chaparral communities (e.g., Black Sage, Toyon). Soil fertility is poor in this ecotonal habitat, a trait supporting chaparral growth. However, sage scrub representation is too high to map such areas as clearly one vegetation type or the other. Chamise is the typical chaparral representative, with Mission Manzanita often present as scattered individuals. California Sagebrush, Flat-top Buckwheat, and Laurel Sumac are the most common sage scrub species. The habitat is generally 4-6 feet in height, and shrub density is considered moderate, creating a habitat which physically is quite similar to the on-site sage scrub. It is expected to be used by-most, if not all, of the reptile, bird, and mammal species occurring in the adjacent or nearby sage scrub. Valley Needlegrass Grassland (Native Grassland) Native grass species are commonly encountered on the property but in most areas they have been reduced to a very small component amidst non-native grass species. Native bunch grasses, primarily Purple Needlegrass (Nassella pulchrd), dominate the cover. Substantial numbers of Blue-eyed Grass (Sysrinchium bellum) were noted in mesic areas. Also present were Big Gumplant (Grindelia camporum var. camporum), Cudweed Aster (Lessingiafilaginifolia var.filaginifolia), Fremont's Camas (Zigadenus fremontii), and at one location Clay Bindweed (Convolvulus simulans). Highly noteworthy is the very localized presence of San Diego Thorn-mint (Acanthomintha ilicifolid), identified in several very small pockets of native grass in areas otherwise dominated by chaparral vegetation. Friable clay soils dominate this localized habitat. Due to the small size of these habitat patches, they are not likely to support important populations of wildlife species. Animals associated with grassland habitat are discussed below, under the Non-native Grassland section, due to the far more extensive cover of non-native grass habitat. Non-native Grassland This community is primarily found in the southern portions of the property. Historically, areas now dominated by non-native grasses probably supported native grasslands, and sage scrub. Conversion from these habitats probably resulted from a combination of disturbances, including agricultural practices, construction of the adjacent industrial park, and possibly unusually frequent fires. Slender Wild Oat (Avena barbatd) was perhaps the most conspicuous dominant species, but brome grasses (Bromus spp.), Italian Ryegrass (Leymus multiflorum), and Red-stem Filaree (Erodium cicutarium) were also strongly represented. In some areas, the canopy was strongly dominated by mustards (Brassica nigra, Hirschfeldia incana). Other common species in the Non-native Grasslands were Bindweed (Convolvulus arvensis), Fennel (Foeniculum vulgare), Tocalote (Centaurea melitensis), Horehound (Marrubium vulgare), and Western Jimsonweed (Datura wrightii). The on-site grasslands are very important foraging and nesting habitat for the breeding pair of Northern Harriers (Circus cyaneus), which fledged two young on-site. The grasslands also receive use by other foraging raptors, as well as grassland-associated species such as the Western Meadowlark (Sturnella neglectd) and California Vole (Microtus californicus). Droppings of the San Diego Black-tailed Jackrabbit (Lepus californicus bennettii) were also noted in this habitat. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 13 Merkel & Associates, Inc. # 97-104-06 December /, 2000 Southern Cottonwood-Willow Riparian Forest This habitat occurs along Agua Hedionda Creek where mature, often well-spaced Western Sycamores (Platanus racemosd), dominated the canopy. Arroyo Willow (Salix lasiolepis), Goodding's Black Willow (Salix gooddingii), and Lance-leaf Willow (Salix lucida ssp. lasiandrd) formed supporting patches of habitat, but did not provide a large band of canopy as occurs farther downstream. Mature Coast Live Oaks (Quercus agrifolia) also contributed substantially to the peripheral canopy. The variable but often open understory contained scattered young willows, Mule Fat, Western Ragweed (Ambrosia psilostachyd), Mugwort (Artemisia douglasiand), Celery (Apium graveolens), Hedge Nettle (Stachys ajugoides var. rigidd), and Poison Oak. Areas delineated as Southern Cottonwood-Willow Riparian Forest in this report have,been categorized as Sycamore Alluvial Woodland by Dudek (1999b) and as Coast Live Oak Riparian Forest by KEA (1998). None of these three categories fit the on-site community particularly well for various reasons. The Sycamore Alluvial Woodland category is fairly accurate from a physical description, but many of the component species do not occur this far to the south, and the habitat is reported to be restricted to areas north of Santa Barbara County (Holland 1986). Use of the Southern Coast Live Oak Riparian Forest category is not recommended due to the lack of emphasis on the willow component; this category is used elsewhere on-site where Coast Live Oaks are the primary component of riparian habitat. The oak component is locally high compared to most sites delineated as Cottonwood-Willow Riparian Forest; however, this category is believed to best represent the mixed deciduous riparian wildlife community, while maintaining distinction for other on-site areas delineated as Southern Coast Live Oak Riparian Forest. Wildlife found using the habitat included many relatively common species of the region. Examples include Black-headed Grosbeak (Pheucticus melanocephalus), Hooded Oriole (Icterus cucullatus), Bullock's Oriole (Icterus bullockii), Orange-crowned Warbler (Vermivora ce/ata),Nuttall's Woodpecker (Picoides nuttallii), Pacific-slope Flycatcher (Empidonax difficilis), and nesting Red-tailed Hawk (Buteo jamaicensis), as well as very common birds such as the Song Sparrow (Melospiza melodid), Lesser Goldfinch (Carduelispsaltria), and European Starling (Sturnus vulgaris). Noteworthy sightings include the Cooper's Hawk (Accipiter cooperii) and Downy Woodpecker (Picoidespubescens). Southern Willow Scrub Relatively small but dense stands of willows (Salix spp.) are found in the south-central portion of the study area. Despite the size, the habitat structure appears suitable for use by the Least Bell's Vireo, but none were observed. Noteworthy in this habitat was the presence of two male Yellow-breasted Chats (Icteria virens), each of which is expected to have been breeding on-site. A migratory Willow Flycatcher (Empidonax traillii) was also observed in this woodland habitat. Mule Fat Scrub Stands of Mule Fat (Baccharis salicifolia) define this relatively minor on-site habitat. It was delineated in a few narrow drainages in the northwest section of the study area. Agricultural fields closely border this habitat, making it of relatively low value to wildlife. Southern Coast Live Oak Riparian Forest This vegetation type is generally defined where Coast Live Oaks dominate the riparian canopy. Occasional in this habitat are Western Sycamore, with various species of willows being uncommon and isolated elements. The understory usually consists of dense Poison Oak and leaf litter. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 14 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Wildlife species commonly identified in the oak riparian woodland included the House Wren (Troglodytes aedori), Nuttall's Woodpecker, Acorn Woodpecker (Melanerpes formicivorus), and Mutton's Vireo (Vireo huttoni). Both the Red-shouldered Hawk (Buteo lineatus) and White-tailed Kite (Elanus leucurus) nested in this oak habitat, and two owl species are known to occur: Barn Owl (Tyto alba) and Great Horned Owl (Bubo virginianus). Another owl species, the Western ScreechrOwl (Otus kennicottii), is reported to occur in areas upstream (Geoff Rogers, personal communication), and may also occur in the on-site oak woodlands. Coast Live Oak Woodland Coast Live Oaks also occur away from drainages, but in most cases they closely blend with the above- described oak riparian forest. The understory is again dominated by Poison Oak, but lacks a streambed component. Other understory species include native species such as Narrow-leaf Milkweed (Asclepias fascicularis) and American Vetch (Vicia americana var. americana), and non-natives such as Goose Straw (Galium aparine), Smilo Grass (Piptatherum miliaceum), Mediterranean Schismus (Schismus barbatus), and Johnsongrass (Sorghum halepense). This oak habitat was observed, or is expected, to generally support similar wildlife species as discussed for the riparian oak woodlands. Cismontane Alkaline Marsh Cismontane Alkali Marsh occurs in a few relatively small patches near the dirt road in the southern portion of the property. Species included here were Southwestern Spiny Rush (Juncus acutus), Spearscale Saltbush (Atriplex triangular is), and Dombey's Spike-sedge (Eleocharis montevidensis). The small size of this habitat is unlikely to support diverse wildlife associated with marsh habitat, but common species such as Song Sparrow and Common Yellowthroat (Geothlypis trichas) were observed. Coastal and Valley Freshwater Marsh Freshwater Marsh habitat is associated with inundated portions of drainages and a small pond. The dominant plant associated with this habitat was Broad-leaved Cattail (Typha latifolia) which forms a dense, five to seven foot tall canopy. Southwestern Spiny Rush is occasionally found at the edges of this habitat type, along with Saltgrass (Distichlis spicatd) and Celery (Apium graveolens). The dense cattail habitat supported Red-winged Blackbird (Agelaius phoeniceus), Common Yellowthroat, Song Sparrow, and Sora (Porzana Carolina). The Northern Harrier was often seen foraging near the marsh habitat in the southeast corner of the property. Freshwater Seep A small area of Freshwater Seep vegetation is delineated just west of the pond located in the central portion of the site. This habitat is characterized by low-growing (one to three feet tall) herbaceous wetland species such as Dombey's Spike-sedge, Mexican Rush, Willow Herb (Epilobium ciliatuni), and Salt Marsh Fleabane (Pluchea odoratd). However, this habitat occurs adjacent to taller trees (e.g., willows) and shrubs (e.g., Coyote Brush); Pampas Grass is rapidly overtaking the general area. These fluctuating canopy heights and the small area of seep vegetation attract both common marsh wildlife such as Song Sparrows, or species associated with surrounding upland habitats (e.g., California Towhee). Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 15 Merkel & Associates, Inc. # 97-104-06 December I, 2000 Emergent Wetland This category identifies a weedy wetland community found within or near drainages. Plant species typical of this wetland type included Bristly Ox-tongue, Annual Beard Grass, and Cocklebur. Wildlife associated with this minor on-site habitat included the Song Sparrow, House Finch (Carpodacus mexicanus), and Lesser Goldfinch. Disturbed Wetland A very small patch (0.1 acre) of Disturbed Wetland occurs adjacent to a detention basin supporting willows and freshwater marsh, located in the south-central part of the study area. This Disturbed Wetland primarily consists of a narrow band of European Tamarisk (Tamarixparviflora) which occupies a shallow drainage leading to the detention basin. Wildlife observed in this habitat included the Common Yellowthroat, Song Sparrow, Red-winged Blackbird, and Lesser Goldfinch. Open Water (Pond) A small pond occurs in the west central portion of the study area (near the western boundary of the Carlsbad Oaks property). A pond of such small size, away from a sizeable drainage, would be expected to be dry for much of the year. However, it is fed by the persistent seep in this south-facing slope. Ornamental/Revegetated Area The slope abutting the commercial development to the south was planted with a mixture of sage scrub species and exotic species. Ornamentals including Eucalyptus (Eucalyptus sp.), Perez Rosemary (Limonium perezii), and a non-native Gumplant (Grindelia sp.) were established through irrigation. Otherwise, the slope would show a fairly good recovery dominated by sage scrub species such as California Sagebrush, Coyote Brush, and Quail Saltbush (Atriplex lentiformis). Exotic Vegetation This category includes areas of Eucalyptus near the agricultural operations, landscape plantings near commercial buildings, and a large stand of Pampas Grass (Cortaderiajubatd) in the central part of the study area. Agricultural Field Row crops occur in the northwest portion of the study area. The open, disturbed condition attracts relatively few species, such as the Say's Phoebe (Sayornis sayd), Black Phoebe (Sayornis nigricans), Killdeer (Charadrius vociferus), and Horned Lark (Eremophila alpestris). Red-winged Blackbird, Brewer's Blackbird (Euphagus cyanocephalus), and European Starling are also regularly found foraging in agricultural areas. Disturbed Areas This category includes various cleared areas, primarily dirt roads, which are so frequently disturbed that they support less than 30% cover by non-native grasses. In some cases these areas are used to store agricultural supplies (stakes, etc.), but generally do not show a permanent impact. Due to their open and disturbed condition, these areas are generally of very low value to wildlife; however, dirt roads passing through native vegetation provide basking sites for reptiles (e.g., San Diego Horned Lizard), and may serve as local travel routes for mammals. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 16 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Urban/Developed The Urban category is applied to paved roads and buildings. It accounts for just under eight acres of the study area. FLORA A total of 250 plant species was identified in the study area. Of this total, 82 species (33%) are not native to the region. The study area contains an excellent mix of plants representing both coastal and inland influences, as exemplified by NuttalPs Scrub Oak and Interior Scrub Oak, and numerous hybrids of these two species. The study area also supports one of the most coastal incursions of Eastwood Manzanita (Arctostaphylos glandulosa ssp. zacaensis). All locations of plants previously identified as Del Mar Manzanita (Arctostaphylos glandulosa ssp. crassifolia) were confirmed to be the similar but non-sensitive Eastwood Manzanita. Del Mar Manzanita is known, however, from relatively short distances to the south and west. This issue is discussed more thoroughly in the Sensitive Resources section of this report. A moderate number of sensitive species are included in the flora. These include Western Dichondra (Dichondra occidentalis), Small-flowered Morning Glory (Convolvulus simulans), Summer-Holly, Engelmann Oak (Quercus engelmannii), San Diego Sagewort (Artemisiapalmeri), Southwestern Spiny Rush, San Diego Goldenstar (Muilla clevelandii), and an abundance of California Adolphia. State and federal listed plant species found on-site are San Diego Thorn-mint and Thread-leaved Brodiaea (Brodiaea filifolid). The site clearly shows strong evidence of disturbance in many areas. This is perhaps best illustrated by the presumed conversion of native grassland/sage scrub in the southern portions of the study area. Conversely, in areas of established sage scrub an open chaparral, Ashy Spike-Moss (Selaginella cinerascens), formerly considered a low sensitivity species, is common. This species is regarded as an indicator of low levels of soil disturbance. An obvious threat to the on-site habitat quality is the expansion of Pampas Grass. Comparison of aerial photographs dated January 4, 2000 and March 1, 1994 clearly show a dramatic expansion of this species in the southwest facing seep area (west/central part of the study area). WETLAND RESOURCES Eight wetland habitat types and two jurisdictional non-wetlands occur on-site (Figure 3, Table 3, map pocket). These are Southern Cottonwood-willow Riparian Forest, Southern Willow Scrub, Mule Fat Scrub, Cismontane Alkali Marsh, Coastal and Valley Freshwater Marsh, Freshwater Seep, Emergent Wetland, and Disturbed Wetland. Additional jurisdictional resources found on-site consist of Non- wetland Waters of the U.S. The wetlands and waterways are discussed in further detail below. Southern Cottonwood-Willow Riparian Forest A total of 22.7 acres of Southern Cottonwood-Willow Riparian Forest vegetation occurs in the western portion of the property, along the site's main drainage. Facultative wetland (FACW) associated Western Sycamores ranging from approximately 50 to 70 feet in height dominate the canopy. Other trees, found in smaller numbers, included Lance-leaf Willow (Salix lucida ssp. lasiandra), an OBL species, and Coast Live Oak, an upland species. The understory of this Riparian Woodland habitat consists of both wetland associated plants such as Mugwort (Artemisia douglasiana) and upland species such as Rip-gut Grass (Bromus diandrus). Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 17 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 TABLE 3. SUMMARY OF WETLANDS AND JURISDICTIONAL NON-WETLAND WATERS OF THE U.S. Wetland or Jurisdictional Habitat Type Southern Cottonwood-Willow Riparian Forest Southern Willow Scrub Mule Fat Scrub Cismontane Alkali Marsh Coastal and Valley Freshwater Marsh Freshwater Seep Emergent Wetland Disturbed Wetland Open Water (Pond) (ACOE jurisdiction only) Non- wetland Waters of the U.S. (streambeds) TOTAL Acres 22.7 13.1 0.3 1.6 ' 3.3 0.3 0.6 0.1 0.3 2.2 44.5 Wetland hydrology for the Cottonwood-Willow Riparian Forest was demonstrated by a braided streambed; jurisdiction extends from bank to bank. Soils in this area were sandy and demonstrated hydric characteristics such as organic streaking. Southern Willow Scrub Large areas of Southern Willow Scrub occur along the drainages in the central portion of the study area. Some smaller areas of Southern Willow Scrub are also found scattered throughout the study area. The canopy of the Southern Willow Scrub habitat found on-site is almost exclusively made up of OBL Lance-leaf Willows and FACW Arroyo Willows (Salix lasiolepis) ranging in height from 20 to 30 feet. Understory components include Mexican Rush (Juncus mexicanus) and Annual Beard Grass (Polypogon monspeliensis), which are FACW species, as well as Coyote Brush (Baccharis pilularis) and Pampas Grass, both upland species. Hydrology was indicated by the presence of drainage patterns and oxidized root channels in the upper 12 inches. Low-chroma color soil and the presence of mottles indicated hydric soils. A total of 13.1 acres of Jurisdictional Southern Willow Scrub was delineated within the study area. Mule Fat Scrub Several small patches of Mule Fat Scrub totaling 0.3 acre occur within the drainages in the western half of the property. The Mule Fat Scrub on-site mainly consists of Mule Fat (Baccharis salicifolid), which is a FACW species. The Mule Fat Scrub also includes other wetland associated plants such as Annual Beard Grass, and Bristly Ox-tongue (Picris echioides). Upland-associated species including Red Brome (Bromus madritensis ssp. rubens) are also found intermixed within the Mule Fat Scrub. Hydrology was demonstrated by drainage patterns; mottling, low chroma soils with mottles indicated hydric soils. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 19 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Cismontane Alkali Marsh Cismontane Alkali Marsh occurs in a few areas scattered in the vicinity of the main road located in the southern portion of the property. This marsh community is dominated by FACW species that can tolerate relatively high soil salinity. Species included here are Southwestern Spiny Rush (Juncus acutus), Halberd-leaf Saltbush (Atriplex triangular is), and Dombey's Spike-sedge (Eleocharis montevidensis). Drainage patterns and oxidized root channels in the upper 12 inches revealed wetland hydrology. Soil pits in these areas revealed a low chroma matrix with mottling. Coastal and Valley Freshwater Marsh Freshwater Marsh habitat is associated with inundated portions of the site's prominent drainages. The dominant plant associated with this habitat is Cattail (Typha latifolia) which forms a closed canopy that is five to seven feet in height. A lower growing marsh species, Southwestern Spiny Rush, is found along the edges of this habitat type, along with a number of other wetland associates such as Saltgrass (Distichlisspicata), Celery, and Bristly Ox-tongue. Soils exhibited hydric characteristics such as sulfidic odor, gleyed or low-chroma colors, aquic moisture regime, and/or organic streaking. Soils were also typically either saturated in the upper 12 inches or inundated. Freshwater Seep A 0.3 acre area of Freshwater Seep vegetation was delineated west of the open water pond located in the central portion of the site. This habitat is characterized by low-growing herbaceous FACW and OBL plants such as Dombey's Spike-sedge, Mexican Rush, Willow Herb (Epilobium ciliatum), and Salt Marsh Fleabane (Pluchea odoratd). Wetland hydrology was demonstrated by oxidized root channels in the upper 12 inches, and low chroma colors with mottling indicated the presence of hydric soils. Emergent Wetland Approximately 0.6 acre of jurisdictional Emergent Wetland occurs within the study area. Plants typical of this Emergent Wetland includes Bristly Ox-tongue, Annual Beard Grass, and Cocklebur (Xanthium strumariwri). The dominance of FAC and FACW species indicates hydrophytic vegetation in these areas. The stands of Emergent Wetland exhibit signs of hydrology in the form of drift lines, sediment deposits, and drainage patterns. Soil samples from test pits revealed hydric soil indicators such as mottles. Disturbed Wetland A small 0.1 acre area of Disturbed Wetland occurs adjacent to a large area of willows and freshwater marsh located in the south-central part of the study area. This habitat type primarily consists of European Tamarisk, a weedy, non-native wetland plant species. Hydrology in this area consists of drainage patterns. Non-wetland Waters of the U.S. Approximately 2.2 acres (95,402.5 square feet) of jurisdictional (ACOE and CDFG) Non-wetland Waters are found within the study area. Non-wetland Waters are composed primarily of incised drainages of varying width that lack hydrophytic vegetation and/or hydric soil indicators. Many of the Non-wetland Waters found on site consist of the drainages that run beneath the Southern Coast Live Oak Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 20 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Riparian Forest. Inundation and saturation in the upper 12 inches further indicated hydrology within these drainages. The lack of hydric indicators such as drainage patterns and drift lines above the incised drainages indicated that the Ordinary High Watermark does not occur above the depth of the channel. Plants which dominated the Southern Coast Live Oak Riparian Forest vegetation include Coast Live Oak, Poison Oak, Pampas Grass, and Laurel Sumac, which are non-indicator species. Although a few facultative or facultative wetland species such as San Diego Sedge and Arroyo Willow are present, they are not present in such abundance to be considered a dominant species, or they do not make up more than 50% of the dominant species. Vegetation occurring within the remainder of the Non-wetland Waters of the U.S. drainages found on- site was typically comprised of Diegan Coastal Sage Scrub or Chaparral (both upland habitats) species. Included here are Flat-top Buckwheat, Laurel Sumac, Black Sage, and Chamise. These upland plants were occasionally intermixed with non-native, invasive species such as Pampas Grass, and/or with wetland-associated species such as Annual Beard Grass (FACW). Once again, although wetland- associated plants sporadically occurred within the drainages, they did not comprise of more than 50% of the dominant species. Therefore, the drainages still lacked the proper hydrophytic vegetation criteria to be considered jurisdictional wetland habitat. The pond habitat (0.3 acre) is also considered a Non-wetland Water of the U.S., and under jurisdiction of the ACOE. However, because the pond is fed by a seep, and not on a defined drainage, it does not fall under jurisdiction of CDFG. Hydric soils indicators were observed within most of the Non-wetland Waters occurring on-site. These indicators consisted of gleyed or low chroma colors, mottling, and/or sulfidic odor. Wetlands Functions and Values The jurisdictional wetlands and waterways on-site represent relatively high quality habitats. The on-site wetlands include large stands of dense, continuous Southern Cottonwood-Willow Riparian Forest and Southern Willow Scrub. These vegetation communities have a high biological value based on factors such as canopy development, understory plant diversity, and wildlife species richness. These vegetation types provide a multi-layer canopy, which supports sensitive riparian birds such as Yellow Warbler and Yellow-breasted Chat, as well as more common species including Song Sparrow, Lesser Goldfinch, Yellow-rumped Warbler (Dendroica coronatd), and Common Yellowthroat. Riparian drainages such as these are important as wildlife movement areas for a variety of detected mammal species including Coyote (Canis latrans), Bobcat (Felis rufus), Gray Fox (Urocyon cinereoargenteus), Striped Skunk (Mephitis mephitis), and Raccoon (Procyon lotor). Additionally, the smaller ponding areas and abundance of leaf litter beneath the larger stands of riparian trees may provide breeding habitat for various amphibian species including the Pacific Chorus Frog (Pseudacris regilla) and Western Toad (Bufo boreas). The heights of the oaks, sycamores, and willows are indicative of a mature, well- developed riparian system. Overall, the on-site wetlands and waterways also have high physical and chemical functions. This is mostly attributed to the areas of the drainages that are vegetated by Cismontane Alkali Marsh and Coastal and Valley Freshwater Marsh habitat. The dense herbaceous vegetation occurring in these communities allows for groundwater recharge, sediment retention, and toxicant retention. The sediment and toxicant retention of these areas improves the conditions of the areas downstream by reducing sediment loading. Nutrient transformation on-site is also expected to be high given the presence of significant woody and herbaceous vegetation, high plant diversity, and alkaline soils. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 21 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 WILDLIFE RESOURCES Butterflies Behr's Metalmark (Apodemia virgulti) was common throughout areas of sage scrub. Other species found in sage scrub, chaparral, or where shrubs were mixed with grassland, included the Brown Elfin (Callophrys augustinus), Acmon Blue (Icaricia acmori), Bernardino Dotted-Blue (Euphilotes bernardino), and Funereal Dusky wing (Erynnis funeralis). The California Sister (Adelpha bredowii californicd) was characteristically found associated with oak woodland, while the similar Lorquin's Admiral (Basilarchia lorquinf) was observed in better quality riparian woodland along Agua Hedionda Creek. Other species found in riparian habitat included Western Tiger Swallowtail (Papilio rutulus), Anise Swallowtail (Pipilio zelicaon), and Mourning Cloak (Nymphalis antiopd). Away from the main drainages, but still in relatively mesic areas or grassland, Common Buckeye (Junonia coenia), Sara Orangetip (Anihocharis sara sard), Cabbage White (Pieris rapae), and White Checkered-Skipper (Pyrgus albescens) were observed. Common Ringlet (Coenympha tuilla) was also present in abundance in grasslands. No sensitive butterfly species are known to occur on-site. Harbison's Dun Skipper (Euphyes vestris harbisonf) could potentially occur in the on-site oak riparian woodlands supporting dense populations of San Diego Sedge (Carex spissd), the larval host plant of this butterfly. Fish The non-native Mosquitofish (Gambusia affinis) was the only fish species observed in the study area. No sensitive or native fish species are expected to occur on-site. Amphibians Three amphibian species are present in the combined study areas. Pacific Chorus Frog (Pseudacris regilld) was occasionally heard calling from riparian and marshy areas, and tadpoles of this species were observed in more downstream portions of Agua Hedionda Creek. Tadpoles of the Western Toad (Bufo boreas) were also observed in this stretch of creek, as was an individual Bullfrog (Rana catesbeiand). Other amphibian species which may occur on-site include the Western Spadefoot (Scaphiopus hammondii), Garden Slender Salamander (Batrachoseps major), and the Ensatina (Ensatina eschscholtzii). Reptiles Despite the direct and indirect effects of human/urban encroachment (mountain biking, hiking, illegal immigrant encampments, and adjacent urbanization to the west, east, and south), the site supports a diverse reptile fauna, including several species considered to be sensitive and uncommon or absent from coastal areas with urban encroachment. The large tract of similar, preserved habitat to the north enhances on-site quality and may account for the abundance of reptile species on-site. Lizard species present included common forms such as the Western Fence Lizard (Sceloporus occidentalis), Side-blotched Lizard (Ufa stansburiand), and Southern Alligator Lizard (Elgaria multicarinatd), and sensitive species including the San Diego Horned Lizard and Orangethroat Whiptail. The San Diego Horned Lizard is not often found near urban development. Other sensitive lizard species which were not observed but may be present are the Coronado Skink (Eumeces skiltonianus interparietalis), Legless Lizard (Anniella pulchrd), and Coastal Whiptail (Cnemidophorus tigris multiscutatus). Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 22 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Snake species identified on-site during the 2000 surveys were the Common Kingsnake (Lampropeltus getuld) and Striped Racer (Masticophis lateralis). A Coast Patchnose Snake (Salvadora hexalepis virgulted) was observed in the study area during a prior investigation of the proposed sewer alignment (M&A 1997), as were the Gopher Snake (Pituophis melanoleucus) and Northern Red Diamond Rattlesnake (Crotalus ruber ruber) (Dudek 1999b). The sensitive Two-striped Garter Snake (Thamnophis hammondii) has good potential to occur in on-site riparian habitats. Other snake species with moderate or better potential to occur on-site are the Western Blind Snake (Leptotyphlops humilis), Coachwhip (Masticophis flageHum), San Diego Ringneck Snake (Diadophis punctatus similis), and Southern Pacific Rattlesnake (Crotalus viridis helleri). Birds Due to the general dominance of sage scrub on the property, as well as open chaparral which functions in a very similar manner as sage scrub, many of the observed bird species were associated with these habitat types. Resident bird species more strictly associated with sage scrub or chaparral included the following: California Quail, California Gnatcatcher, Wrentit, California Thrasher, Bewick's Wren, and Rufous-crowned Sparrow, all of which were common on-site. Also observed were the Greater Roadrunner (Geococcyx californianus) and Common Poorwill (Phalaenoptilus nuttallii). The scrublands also supported several species regarded as habitat generalists in coastal San Diego County. Species noted to be widespread and occurring in a variety of habitat types included Anna's Hummingbird (Calypte anna), Bushtit, Mourning Dove (Zenaida macroura), California Towhee, House Finch, and Lesser Goldfinch. During the winter, the White-crowned Sparrow (Zonotrichia leucophrys) and Yellow-rumped Warbler (Dendroica coronatd) are expected to be abundant and widespread in the study area. Grassland associates were rather limited, and included the Western Meadowlark and Northern Harrier. Other bird species with a preference for grassland habitat which may occur, particularly in the winter season are the Savannah Sparrow (Passerculus sandwichensis) and Vesper Sparrow (Pooecetes gramineus). Flycatchers such as the observed Say's Phoebe and Black Phoebe, often forage in grassland habitat. Two sensitive species, the Loggerhead Shrike (Lanius ludovicianus) and the Grasshopper Sparrow (Ammodramus savannarum), are potential inhabitants of this community but have not been reported from the study area. Raptor species observed nesting in the study area are the Red-tailed Hawk (Buteojamaicensis), White- tailed Kite (Elanus leucurus), and Northern Harrier (Circus cyaneus); the Cooper's Hawk (Accipiter cooperif) and American Kestrel (Falco sparverius) are also resident to the study area and expected to breed in the on-site woodlands. A Peregrine Falcon (Falco peregrinus) was seen soaring over the property in October 2000, and presumably was a migratory or wintering individual. Although the Golden Eagle (Aquila chrysaetos) has been historically observed on-site, it is not resident to the immediate area and unlikely to forage on-site on a regular basis. The Sharp-shinned Hawk (Accipiter striatus), a wintering species to the region, is also documented from the property (Dudek 1999b). Non- raptors observed soaring over the site include the Turkey Vulture (Cathartes aura), Common Raven (Corvus corax), and American Crow (Corvus brachyrhynchos). Cliff Swallow (Petrochelidon pyrrhonotd), Northern Rough-winged Swallow (Stelgidopteryx serripennis), Barn Swallow (Hirundo rusticd), and White-throated Swift (Aeronautes saxatalis) were also commonly observed flying over the property. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 23 Merkel & Associates, Inc. # 97-104-06 December I, 2000 Mammals Predatory species identified in the study area were the Coyote, Bobcat, and Gray Fox. Other carnivores detected were the Raccoon and Striped Skunk. The non-native Virginia Opossum (Didelphis virginianus) is also expected to be present. Despite the suitable habitat, Mule Deer (Odocoileus hemionus) appear to be absent from the study area, as no tracks or droppings were identified during the surveys. California Ground Squirrel (Spermophilus beecheyi) and Desert Cottontail (Sylvilagus audubonii) were common on-site, and limited amounts of sign indicated that the Black-tailed Jackrabbit was present but probably uncommon or rare in the study area. Stick nests and droppings of both the San Diego Desert Woodrat and Dusky-footed Woodrat (Neotomafuscipes) were observed, as well characteristic mounds of Borta' s Pocket Gopher (Thomomys bottae). Other expected rodent species include the California Vole (Microtus californicus), San Diego Pocket Mouse (Chaetodipus fallax fallax), Pacific Kangaroo Rat (Dipodomys agilis), Western Harvest Mouse (Rheithrodontomys megalotis), Deer Mouse (Peromyscus maniculatus), and Cactus Mouse (Peromyscus eremicus). These rodents and rabbits combine to form an important prey base for carnivores, raptorial birds, and snakes. Bats are another mammal group expected to occur on-site; however,high quality roosting habitat is limited to very old trees in the extreme northwestern arm of the study area. Species which may forage on-site include the California Myotis (Myotis californicus), Yuma Myotis (Myotis yumanensis), Big Brown Bat (Eptesicusfuscus), Pallid Bat (Antrozouspallidus), and Brazilian Free-tailed Bat (Tadarida brasiliensis). Wildlife Movement Corridors Wildlife corridors can be defined as linear landscape features that allow animal movement between two patches of habitat. Corridors are typically thought of as facilitating concentrated wildlife movement through areas where natural topography (e.g., cliffs or steep slopes, or by providing cover from predators) or urbanization limit animal passage. Corridors may function in different ways, depending upon the time of year and the species being considered. Wildlife corridors can be classified as short, local, or regional corridors. Short corridors typically serve the daily needs of individuals, and can be referred to as travel routes. A short corridor may allow an animal to pass through unsuitable habitat in order to access water, a den site, or a foraging area. Short corridors regularly exist for individual animals within the study area, but impacts to these travel routes would not be considered significant unless all reasonable access to a critical resource (e.g., water source) is being severed by project development. A local corridor works on a slightly larger scale and generally allows movement between discrete habitat patches. By connecting two or more habitat patches, local corridors allow the patches to function as a larger block of habitat. Such connections may allow persistence of species or populations which could not be accommodated by any one of the component patches. In the case of the present study area, disruption of existing local corridors by the project elements (road, sewer, commercial development) are not expected to be a significant issue. This is because the existing habitats, though sometimes patchy, are not currently considered to be isolated from one another. However, implementation of project elements does have the potential to fragment the site into multiple patches. While the projects may not directly eliminate a species, they could create, or result in increased importance of, local corridors needed for a species to persist in the remaining habitat. This could be the case for species such as the Bobcat, Coyote, or Gray Fox; however, more likely is that these species would be directly or indirectly eliminated from the study area, or would persist in lower numbers of individuals isolated in contiguous habitat patches on- and/or off-site. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 24 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Regional corridors work over a much broader scale, and enable movement between very large tracts of undeveloped land. Natural corridors (i.e., not formed by urban encroachment) typically are found either along canyon bottomlands or ridgelines because these features often provide relatively unobstructed and easier travel routes. For the same reason, dirt roads, trails, and firebreaks may also be favored through dense vegetation. Preferred corridors also typically provide cover from predators, which another reason why riparian areas are commonly used for wildlife movement. The study area is part of Core #5 in the City of Carlsbad's Habitat Management Plan (HMP), and is connected to Core #6 via Link D (Figure 4). The main southerly on-site drainage extending east-west through the study area is considered a regional wildlife corridor based upon its riparian habitat and available cover, and other factors including the surrounding existing and proposed development (as shown in the HMP for the Carlsbad Oaks North development). This corridor was also identified in the biological investigations of KEA (1998). This drainage provides the only available avenue for wildlife movement (eastward, then south) through the study area to reach the Carlsbad Raceway property (the northwestern section of Link D). Though tenuous, Link D then connects southward across Palomar Airport Road to lands to the south. On the other side of the study area, Agua Hedionda Creek allows for wildlife movement to the west (toward Agua Hedionda Lagoon) and north (through Los Monos Canyon). The HMP also shows connection of Core #5 to Core #3 through Link C (refer Figure 4). Link C consists of a mix of sage scrub and agricultural fields. SENSITIVE SPECIES Sensitive Plant Species Identified On-Site The following information is based on Reiser (1996). San Diego Thorn-mint [Acanthomintha ilicifolia (Gray) Gray] Listing: CNPSListlB R-E-D Code 2-3-2 State/Fed.Status - CE/FT LAMIACEAE Apr.-Jun. Global Rank G1 State Rank S1.1 Distribution: San Diego County; Baja California, Mexico Habitat: Grassy openings, often within chaparral or sage scrub, with friable or broken clay soils are the characteristic habitat of this species. These small clay lenses may be associated with Las Posas or San Miguel-Exchequer soils. Typically, the microhabitat favored by San Diego Thorn-mint is quite distinctive. Only spring annuals, bulbous perennials, and a few herbaceous elements are found with this small annual. All sites examined have a crumbly and/or deeply fissured soil which noticeably compresses, even during the dry season. Associates: Sisyrinchium helium, Bloomeria crocea, Convolvulus simulans. Known Sites: Known populations of San Diego Thorn-mint are typically small. Extant colonies are found in Mission Trails Park, in Alpine, and at several locations near the summit of McGinty Mountain. Other populations are known from Poway, Suncrest, near Lower Otay Reservoir, Otay Mesa, Olivenhain, Encinitas, San Marcos, on Viejas Grade at Poser Mountain, near Sycamore Regional Park, and near Ramona. Reported locations near the present study area include near Carlsbad Raceway in San Marcos, and at the Carillo Ranch near El Fuerte Street in Carlsbad.

This species may be difficult to detect in the fall and winter unless one is familiar with its distinctive microhabitat. These often tiny plants remain rigid and retain their distinctive shape well into the dry season. While this annual can be raised from seed, suitable friable clay microhabitats are quite uncommon and place strict limitations on establishment of new populations. Given the very small total area utilized by a typical population, and the tenuous long-term prognosis for such limited microhabitats in a heavily urbanized region, existing sites with under 100 plants flowering in a typical rainfall year need to be well protected from human incursions. All larger populations should be fully protected. Project Site: Five patches of San Diego Thorn-mint are known to occur in the study area. Four of these are in the southwest corner, and generally well-distanced from the existing access road. The other site, supporting approximately 200 plants, is located just west of the oak-dominated drainage, and approximately 1400 feet east of the current termination of Faraday Avenue, in the western portion of the study area. R-E-D Code: formerly 2-2-1 ASTERACEAE Jul.-Sep. San Diego Sagewort \Artemisiapalmeri Gravl Listing: CNPS: recently de-listed State/Fed. Status - None Global Rank G2? State Rank S2.1 Distribution: Coastal San Diego County; Baja California, Mexico Habitat: San Diego Sagewort is primarily found along creeks and drainages near the coast; inland it may occur in mesic chaparral conditions. In its more usual riparian context, San Diego Sagewort grows within a shaded understory beneath willow, sycamore, or cottonwood. Occasionally it also is seen beneath Quercus agrifolia, but in decidedly mesic circumstances. Known Sites: San Diego Sagewort is most often seen within perennial drainages. Penasquitos Creek is typical of such habitat and supports extensive population from Poway to Interstate 5. A significant population is found scattered along Escondido Creek and its tributaries from Olivenhain northeastward to the Questhaven Retreat. It is occasional beneath oaks in the drainages north of Mt. Israel Road and on the north-facing slopes of Rose Canyon. The southeastern-most reported location is in a creek just east of Glen Lonely near 2000 feet in elevation. San Diego Sagewort is occasional within the Tijuana River Valley, scattered on the shores of San Vicente Reservoir, and in shaded chaparral southwest of the Barona Indian casino. Status: San Diego Sagewort is declining in the U.S. and being impacted by numerous local projects that channelize or disrupt minor drainages, or via massive flood control efforts. However, it is much more common than reported in the 1994 CNPS Inventory of Rare and Endangered Vascular Plants of California, and was recently de-listed by CNPS. Project Site: Two patches of San Diego Sagewort are found at the eastern side of the study area. Approximately 30 individuals occur on-site. Thread-leaf Brodiaea \Brodiaea filifolia Wats.1 R-E-D Code 3-3-3 AMARYLLIDACEAE Mar.-Jun. Listing: CNPS List IB State/Fed.

Associates: Sisyrinchium bellum, Nassella pulchra, Microseris species. Known Sites: A very large population is still extant in the fields near Linda Vista Drive and Las Posas Road in San Marcos. It is very rare on a hillside near Guajome Regional Park. A small colony is still extant on a grassy knoll north of Palomar Airport Road and west of El Camino Real. Data Base reports include a number of small populations in San Marcos and Carlsbad (general areas of Palomar Airport and the Carlsbad Raceway). A sizeable population is still extant at the Nature Conservancy's Santa Rosa Plateau Preserve and many additional sites in western Riverside County. In Orange County a population occurs on the west flanks of Bell Canyon in the foothills of the Santa Ana Mountains; another report is from near El Toro Road. ' • Status: Thread-leaf Brodiaea is still substantially declining throughout its southern California range. This species is systematically being eliminated by numerous, unrelated construction projects around the Palomar Airport and San Marcos areas. Populations near the City of Hemet may be similarly imperiled. This brodiaea grows in open grasslands and sage scrub from a corm, and is difficult to census except during its short flowering season: typically around May. As a result, surveys out of season may not discover its presence. All populations should be fully protected. Project Site: Twenty individuals were observed during a prior survey of the southern sewer alignment (M&A 1997). R-E-D Code: formerly 1-2-2 POLYGONACEAE Apr.-Jun. Prostrate Spineflower [Chorizanthe procumbens Nutt.1 Listing: CNPS - Recently de-listed State/Fed. Status ~ None Global Rank G3? State Rank S3.1? Distribution: San Diego County, Riverside County, Orange County, Los Angeles County, San Bernardino County, Ventura County; Baja California, Mexico Habitat: Sandy openings in Chamise Chaparral are typical habitat for the Prostrate Spineflower; however, it may also occur in sage scrub. It regularly occupies recently disturbed microhabitats such as the shoulders of dirt roads or areas of lightly brushed chaparral. Known Sites: The Prostrate Spineflower grows in chaparral openings at Poway near the proposed Midland Road extension. It is locally common at Rancho Cuca, Alpine, Fallbrook, and near Pala. Other small populations reported include in Pamo Valley near Orosco Ridge, Whale Peak near Ballena, within La Zanja Canyon, Bonsall, and close to the Miramar Landfill in open Chamise Chaparral This Spineflower is found as far north as a barren, rocky butte near Winchester in western Riverside County, but is apparently quite uncommon in this region. Status: Prostrate Spineflower is stable and apparently wide ranging in the undeveloped parts of the County. Substantial potential habitat occurs in little explored chaparral in the San Pasqual region. Project Site: This small but widely distributed plant was recently de-listed by CNPS, and is therefore no longer considered to be sensitive. Summer-Holly (Comarostaphvlis diversifolia (Parry) Greene ssp. diversifolid] Listing: CNPS List IB State/Fed. Status ~ /Former C2 Global Rank G3T2 State S2.2 R-E-D Code 2-2-2 ERICACEAE Apr.-Jun. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 28 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Distribution: San Diego County, Riverside County, and Orange County; Baja California, Mexico Habitat: Mesic north-facing slopes in Southern Mixed Chaparral is the preferred habitat of this large, showy shrub. Rugged steep drainages seem to be a preferred location for isolated shrubs. Most of the population of Summer-Holly occurs west of Interstate 15. In the larger populations, the surrounding mature chaparral is typically tall, dense, and luxuriant. Associates: Ceanothus verrucosus, Xylococcus bicolor, Heteromeles arbutifolia. Known Sites: A large population with hundreds of mature shrubs was found south of Encinitas Road and just northwest of Montura Road in San Marcos; most of the population was lost to residential grading. At least 1000 shrubs grow on the north slopes of Double Peak in San Marcos. A scattered, healthy population of shrubs occurs on the north-facing slope of Mount Whitney. A few were seen near Seal Rock in the Merriam Mountains and others occur nearby west of Interstate 15 flanking Lawrence Welk Estates. Limited populations are found in La Zanja Canyon, in Rancho Penasquitos, Mount Soledad, San Dieguito County Park, north of Faraday Avenue at the entrance to the proposed Carlsbad Golf Course, Del Mar Heights, and Mission Trails Regional Park. The shrub is scattered lightly at several sites in the San Marcos Mountains, and in Rancho Santa Fe on eroded east-facing slopes. Status: Summer-Holly is declining throughout its U.S. range. A few large populations occur within or near the City of San Marcos where they are imperiled by residential development and warrant dedicated biological open space protection. Elsewhere the species is slowly but steadily declining. Project Site: Summer-Holly is distributed along or near drainages and on north-facing slopes within the Southern maritime chaparral/NuttalPs scrub oak phase vegetation. An estimated 100 individuals occur in the study area. Small-flowered Morning Glory \Convolvulus simulans Perrvl R-E-D Code 1-2-2 CONVOLVULACEAE Mar.-Jun. Listing: CNPS List 4 State/Fed.

It is also reported from ultra-mafic ridgelines. Associates: Acanthomintha ilicifolia, Microseris species, Plantago rhodosperma. Known Sites: This morning glory is found in San Diego County on a small mesa on the north slopes of Otay Valley east of Rock Mountain. It also occurs north of Palomar Airport Road east of the Carlsbad Raceway. Herbarium specimens document populations from the Sweetwater Valley, Vista, Otay Ranch, and Casa de Oro near Spring Valley. Historical reports also identify populations from Rancho Santa Fe, Lemon Grove, and La Costa. Status: Small-flowered Morning Glory is declining in southern California due to loss of habitat. The distinctive friable and very crumbly clay soils where this species is usually found are now quite rare in southern California. Such areas are generally very small, often less than 1000 square feet in size, and have sometimes been graded. All substantial populations in the southern portion of the State should be protected. Project Site: Approximately 200 individuals were observed with the most northern population of Acanthomintha, approximately 1400 feet east of the termination of Faraday Avenue. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 29 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Western Dichondra (Dichondra occidentalism Listing: CNPS List 4 R-E-D Code 1 -2-1 State/Fed. Status -- none CONVOLVULACEAE Mar.-May Global Rank G4 State Rank S3.2 MSCP - none Distribution: Santa Barbara County, Ventura County, Los Angeles County, Orange County, San Diego County, Santa Catalina Island, Santa Cruz Island, San Miguel Island, Santa Rosa Island; Marin County (questionable); Baja California, Mexico. Habitat: Southern Mixed Chaparral, Chamise Chaparral, Coastal Sage Scrub, rocky outcrops in grasslands, and especially recently exposed areas of post-burn habitat may all be occupied by this small, cryptic perennial herb. It often grows nearly hidden at the base of leafy shrubs. Soil tolerances for Dichondra appear variable. Associates: Ceanothus verrucosus, Cneoridium dumosum, Arctostaphylos glandulosa ssp. crassifolia. Known Sites: Most historical sites are clustered near the immediate coast. Western Dichondra is occasionally common following burns in coastal San Diego County, and is potentially present at many coastal San Diego County sites in chaparral or Coastal Sage Scrub vegetation. Along the coast, this species has been documented from the Tijuana Hills, Soledad Mountain, the Del Mar region, Encinitas, Solana Beach, Carlsbad, and Oceanside. It is a dominant understory element at the Torrey Pines State Reserve, and widely dispersed in chaparral habitat on Camp Pendleton with sightings extending throughout the San Onofre Mountains. Inland localities include the Jamul Mountains, Otay Mountain, near Lower Otay Lake, Rancho Santa Fe, and the southern flanks of Penasquitos Canyon. Status: Western Dichondra is slowly declining in coastal southern California and is a borderline species for inclusion on the CNPS list. Sites with very high densities are noteworthy; in such circumstances substantial portions of these populations should be protected. Project Site: Western Dichondra is found in the southern portions of the property, with several hundred individuals noted as a localized understory element beneath Chamise Chaparral. Southwestern Spiny Rush \Juncus acutus L. ssp. leopoldii (Parl.) Snog.1 R-E-D Code 1-2-1 JUNCACEAE May-Jun. Listing: CNPS List 4 State/Fed. Status ~ None Global Rank G5T5 State Rank S3? Distribution: San Diego County, Los Angeles County, Santa Barbara County, Ventura County, Orange County, and San Luis Obispo County; Baja California, Mexico Habitat: Coastal Salt Marsh at brackish locales, Alkaline Meadows, and riparian marshes are all utilized by this rush. At mid-elevations this species may occur in limited numbers along drainages with willow riparian vegetation or sycamore woodland. It usually drops out of the flora at moderate elevations. Known Sites: This distinctive large bushy rush is common in marshes throughout coastal San Diego County. It is abundant in the San Diego River flood control channel west of Interstate 5, and common in the Sweetwater River, Otay River (including Salt Creek), San Diego River through Mission Gorge, and the San Dieguito River.- This rush is frequently found on the eastern periphery of the coastal lagoons such as Agua Hedionda, San Dieguito, and San Elijo. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 30 Merkel & Associates, Inc. #97-104-06 December 1, 2000 Status: Southwestern Spiny Rush populations in San Diego County are now stable despite several decades of losses associated with widespread regional reductions in wetlands. This species can be readily grown in suitable habitat. Project Site: This conspicuous shrub occurs in the on-site drainages, with perhaps a few hundred individuals occurring in the study area. R-E-D Code 2-3-2 ALLIACEAE Apr.-May San Diego Goldenstar (Muilla clevelandii) Listing: List IB State/Fed. Status — none/Species of Concern Global Rank G2 State Rank S2.1 MSCP - Covered Species Distribution: San Diego County; Baja California, Mexico Habitat: Native Grasslands, particularly near Mima Mound topography or the vicinity of vernal pools, is the preferred habitat of this perennial corm. This plant does not typically grow in the shade of woody perennials, but rather in somewhat open conditions. Redding Cobbly loams are mapped for locations near Miramar, while Stockpen gravelly clay loam is found with the populations on northeastern Otay Mesa. Given the lack of shrubs associated with Muilla, clay soils with good shrink/swell potential are obviously preferred. Associates: Nassella pulchra, Sisyrinchium helium, Bloomeria crocea, Dudleya variegata. Known Sites: San Diego Goldenstar occurs mostly along the coast from Otay Mesa to San Marcos. Significant populations occur at Otay Mesa, San Miguel Mountain, MCAS Miramar, Mission Trails Regional park, and in the vicinity of the Sycamore Landfill property. Major populations covering many acres were reported from Proctor Valley, as well as by Escondido Creek near Via de las Flores. Status: San Diego Goldenstar is severely declining with the urban expansion of the City of San Diego and outlying cities and communities. This species is likely to be heavily impacted in the next decade by continued urban expansion, such as by the proposed Otay Ranch and Rolling Hills Ranch developments in Chula Vista, and expected severe potential secondary impacts from an influx of humans into this still lightly utilized area. Currently this species is not being adequately protected, and a number of development sites with good potential for occurrence are not being adequately censussed in the spring; it is difficult to identify except when in flower during this period. During years of poor rainfall, as with the late 1980s, this corm may not flower, or deceptively bloom in only limited numbers. Populations have undoubtedly declined substantially within the last two decades, along with the loss of peripheral vernal pool habitat. All substantial populations should be protected; significant portions of smaller populations should also be protected (Reiser 1996). Project Site: One individual was reported from the southern portion of the study area. Suitable habitat and clay soils suggest that this species is more abundant than was indicated by the single sighting. Coast Scrub Oak \Ouercus dumosa Nutt. in parti Listing: CNPSListlB R-E-D Code 2-3-2 State/Fed. Status ~ /Species of Concern FAGACEAE Feb.-Mar. Global Rank G2 State Rank S1.1 Distribution: San Diego County, Orange County, Santa Barbara County; Baja California, Mexico Habitat: Coastal chaparral with a relatively open canopy cover is the preferred habitat in flat Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 31 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 terrain; on north-facing slopes this shrub may grow in dense stands. Chesterton fine sandy loams are mapped for the Miramar Naval Airbase population. It often has a rounded, almost "pruned" aspect which is quite different than the more erect growing Quercus berberidifolia. In addition, the leaves tend to be smaller, more spinose, and quite undulate. Associates: Ceanothus verrucosus, Xylococcus bicolor, Arctostaphylos glandulosz ssp. crassifolia. Known Sites: Coast Scrub Oak occurs at a variety of locales such as Point Loma and Torrey Pines State Park along the immediate coast. Occasionally it occurs inland such as on the Miramar Naval Airbase where it grows in considerable numbers, in the hills at Camp Elliott, and on the northwestern slopes of Otay Mesa. Numerous populations are now isolated in the urban canyons of San Diego City neighborhoods north of Mission Valley such as Linda Vista and Clairemont. This oak is locally common near Del Mar, on the northern flanks of Soledad Mountain in La Jolla, and on north- facing slopes in Rancho Santa Fe. The largest population is within the Penasquitos Canyon Preserve where it is often a dominant shrub and occurs by the tens of thousands. Shrubs in the canyon south of Paseo del Lago in Carlsbad show some hybrid traits, while plants just west of 1-5 in San Elijo County Park clearly show intermediate traits with Q. berberidifolia. Status: Coast Scrub Oak is substantially declining in San Diego County due to urban expansion along the coast. Taxonomic work is necessary to determine the frequency of intergradation between this species and the common Quercus berberidifolia. Obvious hybrids between the Coast Scrub Oak and Quercus engelmannii are found at a number of locations in coastal San Diego County. Sizeable portions of larger populations are recommended for protection. Project Site: Assessing the extent of the on-site population of this species is especially difficult because it is the dominant and defining shrub for the on-site Southern maritime chaparral/Nuttall's scrub oak phase vegetation. As many as 37,000, individuals are estimated to occur in the study area. Sensitive Plant Species Potentially Occurring On-Site A number of additional sensitive plants are known from the region. Small-flowered Microseris (Microseris douglasii var.platycarpha) and Palmer's Grapplinghook (Harpagonellapalmeri) all grow on cracked clay soils such as those present in the study area. The first of these species flowers very poorly during years of low rainfall and is potentially present on site; presence would be significant. Blochman's Dudleya (Dudleya blochmaniae ssp. blochmaniae) is found at the northwest corner of the Palomar Airport property, but most populations occur in proximity to the immediate coast and this species is not expected to occur on-site. Not seen were conspicuous shrubs such as Coast White Lilac (Ceanothus verrucosus) and San Diego Marsh Elder (Iva hayesiand), as well as vernal pool endemics. Sensitive Wildlife Species Identified On-Site San Diego Horned Lizard (Phrynosoma coronatum blainvillii} Listing: USFWS - Species of Concern CDFG - Species of Special Concern, Protected Carlsbad HMP - Not presently covered, but may be added under the MHCP Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 32 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Distribution: The San Diego Horned Lizard ranges from southern Kern County, southern Ventura County and the Los Angeles basin southward through Orange, San Bernardino, Riverside, and San Diego counties into northern Baja California, Mexico. Habitat: Chaparral, sage scrub, montane forest, oak woodlands, and grasslands are all utilized by this lizard. Generally it is found in relatively level or gently sloping terrain. It sometimes occurs along seldom used dirt roads where native species of harvester ants, its typical prey item, are particularly prevalent. Status: Horned lizards in coastal San Diego County are declining, primarily due to habitat destruction and habitat degradation. Also, the expansion of non-native ant species, at the expense of native ant species, may be another factor in the local decline of Horned Lizards. Study Area: On-site chaparral and sage scrub are well suited to horned lizards,'and this species' principal prey item (harvester ants) is common on the property. Despite the site's apparent relatively high use by mountain bikers and hikers, several sightings were made of horned lizards on the dirt roads and trails, generally in the more northern portions of the study area. Orangethroat Whiptail (Cnemidophorus hvpervthrus) Listing: USFWS - Species of Concern CDFG - Species of Special Concern, Protected Carlsbad HMP - Covered Species Distribution: Limited in its California distribution, this lizard ranges northward to Corona Del Mar in Orange County and Colton in San Bernardino County, then southward to western Riverside County, San Diego County, and to Loreto in southern Baja California, Mexico. Habitat: Areas of sage scrub, open chaparral, and peripheral edges of riparian zones and washes are all utilized by this lizard. Status: This species is still relatively common in areas where good habitat occurs; however, vast areas of former habitat in the coastal lowlands have been converted to urban and agricultural development. Project Site: Observations suggest that the Orangethroat Whiptail is present in moderate numbers in the study area. Sightings were predominantly made in sage scrub and chaparral vegetation, but this species is also expected in other shrubland and woodland habitats. Coast Patchnose Snake (Salvadora hexalepis virgulted] Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: The Coach Patchnose Snake ranges from the Santa Barbara area south to near the San Quentin region in Baja California, Mexico. It is found from the western desert edge to the coast. Habitat: This diurnal to crepuscular snake is found in sage scrub and chaparral from the coast up to approximately 6000 feet in elevation. Lizards, especially whiptails (Cnemidophorus sp.) are a favored prey item. Status: As it is uncommonly encountered, the abundance is not well known for this species. Reportedly this snake is most active late in the afternoon and early evening when few surveys are in progress. Study Area: The Patchnose Snake was observed in the study area in 1997 (M&A 1997). Due to Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 33 Merkel & Associates, Inc. # 97-104-06 December I, 2000 high levels of human use and adjacent habitat loss, only a small population of Patchnose Snake is expected on-site. Northern Red Diamond Rattlesnake (Crotalus ruber ruber) Listing: USFWS - Special Concern Species CDFG - Species of Special Concern Carlsbad HMP - none Distribution: Within its limited United States range, this species is confined primarily to areas from the Peninsular Ranges westward to the coast. Northern Red Diamond Rattlesnakes are found from extreme southern Los Angeles County and near Pioneertown in Morongo Valley, southward into Baja California, Mexico. Habitat: This snake typically occupies rocky outcrops and areas of heavy brush or rugged terrain in chaparral, sage scrub or desert scrub on both coastal and desert slopes, usually below 4000 feet. Status: The Northern Red Diamond Rattlesnake is still fairly common where extensive areas of habitat remain. This species is considered sensitive due to its limited U.S. range. Project Site: The Northern Red Diamond Rattlesnake was observed during previous on-site investigations by Dudek (1997). The chaparral and sage scrub vegetation, particularly in the more northern portions of the site where there is more substantial composition of rock outcrop. Northern Harrier (Circus cyaneus) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: Northern Harriers are widespread across North America, but are a very localized breeder. Habitat: Preferred habitats are generally low-growing vegetation types such as marshes, grasslands, and agricultural fields. Status: The Northern Harrier is still a relatively common wintering species in southern California, but breeding has greatly declined in southern California due to loss of suitable breeding habitat. Study Area: A pair of Northern Harriers successfully nested and fledged two young on-site in 2000. This confirmed breeding is the only recent known location within the City of Carlsbad; no breeding locations were known during the preparation of the Carlsbad HMP (Wayne Spencer, Conservation Biology Institute, personal communication). Although the most characteristic harrier foraging habitat on-site consists of grassland and marshes, predominantly occurring in the southern half of the study area, the adults were seen flying over much of the eastern half of the property over the course of the spring and summer site visits. Cooper's Hawk (Accipiter cooperii) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - Covered Species Distribution: Cooper's Hawks are found throughout the United States. Habitat: Cooper's Hawks are primarily found in native riparian, oak, or coniferous woodlands, Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 34 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 and less commonly in eucalyptus. In the non-breeding season, Cooper's Hawks may be found in a variety of lower quality woodland, scrubland, and grassland habitats. Status: This hawk has declined throughout California as a breeding species (Remsen 1978). Project Site: Cooper's Hawks were frequently observed in or near the oak/riparian woodland just downstream of the confluence of Agua Hedionda Creek and the unnamed drainage, in the northwestern portion of the study area. This species is believed to have nested in this general area, but a specific nest site was not identified. Cooper's Hawks were also observed in this general vicinity during prior biological surveys (KEA 1998; Dudek 1999b), and in the regional data base also reports Cooper's Hawk in this area. In 2000, Cooper's Hawks were also seen flying over other portions of the study area, but less consistently, and only a single pair is believed to be resident to the property. / Sharp-shinned Hawk (Accipiter striatus) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - none Distribution: Fairly common winter resident in southern California; possibly breeds in northern California. Habitat: The Sharp-shinned Hawk is primarily associated with mixed woodlands, but during its winter period in southern California it may be found foraging in most habitat types. Status: This species formerly nested in southern California mountain ranges. It may still nest in the San Jacinto Mountains, although summer sightings are rare, and its breeding status is uncertain. Project Site: Sharp-shinned Hawks were observed during prior surveys by Dudek (1999b), and are expected to be an uncommon but regular winter visitor to the study area. White-tailed Kite (Elanus leucurus) Listing: USFWS - none CDFG - Protected (also formerly a Special Animal) Carlsbad HMP - none Distribution: Central Valley and coastal California; extensions north into Oregon and south into northern Baja California, Mexico. Habitat: White-tailed Kites occur in grasslands, agricultural fields, and shrublands of California's coastal valleys and plains. Marshes and grassy bottomlands where large clumps of trees are adjacent to foraging habitat are favored sites for winter roosts. Status: The centers of abundance for these raptors in southern California are the coastal valleys and plains of San Diego, 'Orange, and western Riverside counties, which are the areas which are currently undergoing large-scale and rapid habitat conversion due to residential development. While historic population fluctuations have made their present status difficult to determine, the numbers of breeding individuals are thought to be declining locally in some areas, and wintering populations may be diminishing as well due to loss of winter foraging habitat and roost sites. Project Site: White-tailed Kites were observed on nearly every site visit, and in 2000 were observed nesting in oak woodland in the southeast portion of the study area. They were previously identified in oak woodland near the southwest corner of the study area (downslope and east of the current termination of Faraday Avenue). Though only one pair was found to be resident during 2000, there is potential for the site to support a second pair. The site may also receive additional use by kites in the fall/winter season. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 35 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 American Peregrine Falcon (Falcoperegrinus anatuni) Listing: USFWS - none (formerly endangered but recently de-listed) CDFG - Fully Protected (formerly endangered but de-listed in 1999) Carlsbad HMP - Covered Species Distribution: Peregrine Falcons occur along the Pacific and Atlantic coasts, and have an irregular distribution from Arizona/New Mexico northward to southern Montana. Habitat: Peregrine Falcons can be found foraging over estuaries, coastlines, mountains, open fields, and coastal scrub in California. This species is generally regarded as a bird of open wetlands, often near cliffs or other prominent perches. Generally a fall and winter visitor (early September through April) to San Diego, a small population is now resident in the region and breeding in low numbers. Up to ten pairs formerly nested in San Diego County; documented sites were at San Onofre, Pala, Escondido, San Pasqual, La Jolla, and Point Loma (Unitt 1984). Currently, this species is most frequently seen near the coast such as about Mission Bay and San Diego Bay, where nesting pairs have established (e.g., Coronado Bridge). Status: A small local population has stabilized and may be slowly increasing. This falcon had severely declined as a breeding species in California due largely to the use of DDT and possibly other pesticides. Peregrine Falcons were recently de-listed from Endangered Species status due to population stability and increases, but this remains a rare species in southern California. Project Site: A Peregrine Falcon was observed over the study area in October 2000. Occasional site use is expected, but it is unlikely that the site receives intensive foraging use by this falcon. This is a rare but regular winter visitor to the region, with most observations made near the coastal lagoons and bays which attract concentrated shorebird/waterbird activity. The closest known nesting Peregrine Falcons occur in the vicinity of San Diego Bay. California Horned Lark (Eremophila alpestris actia) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - none Distribution: Several subspecies of Horned Larks occur throughout North America. Although several other subspecies are reported to occur and may breed in San Diego County, E.a. actia is reported to be the most common on the coastal slope. Habitat: Sandy shores, bare ground, grassland, open agricultural land, and open scrubland. Status: The Horned Lark is a common breeding resident, abundant migrant, and winter visitor in southern California. Project Site: Horned Larks were observed on the dirt roads and open agricultural fields at the northwest corner of the study area. There is only limited potential for nesting in this area due to ongoing agricultural activities. Coastal California Gnatcatcher (Polioptila californica californica} Listing: USFWS - Threatened (Date listed: March 25,1993) CDFG - Species of Special Concern Carlsbad HMP - Covered Species Distribution: Currently occurs in San Diego, Riverside, and Orange counties south to Baja California, Mexico. It has largely been extirpated from Ventura, Los Angeles, and Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 36 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 San Bernardino counties. Habitat: Primary habitat of the California Gnatcatcher is Coastal Sage Scrub, but Maritime Succulent Scrub and open chaparral are also used. Status: California Gnatcatchers have seriously declined due to loss of habitat. Between 85% and 90% of this species' habitat has been lost to urban or agricultural development. Within the United States, San Diego County is to be the center of abundance for this species. Project Site: Four California Gnatcatcher territories were identified in the study area (refer Figure 2 or map pocket). Two territories were recorded by KEA in more western portions of the study area, but no California Gnatcatchers were observed in these areas during the 2000 season. Habitat in these areas is at least marginally suited to gnatcatchers, and there is good potential for them to become occupied at some p'oint in the future. Yellow Warbler (Dendroicapetechia brewsteri) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - none Distribution: The Yellow Warbler is occasional in the summer throughout the western United States (except in desert areas, where sometimes a migrant), and is also in the north- central and northeastern U.S. and Canada. This was formerly a widespread breeder in riparian habitats throughout California. The population declines over the past few decades is believed to be caused by habitat loss and possibly brood parasitism by Brown-headed Cowbirds. Habitat: Although this species can be found in a variety of riparian woodland/scrubland habitats during migration, breeding populations are usually associated with mature riparian woodlands. Status: Yellow Warblers have severely declined due to both destruction of riparian woodland and a population explosion among Brown-headed Cowbirds. This warbler has been identified as one of the three species most frequently parasitized by cowbirds (Ehrlich et. al. 1988). In the past few years, this numbers of this species appear to be increasing. It could be that this species is benefitting from efforts to control Brown- headed Cowbirds. Study Area: Five Yellow Warblers were identified (by sight and/or song) in riparian woodlands of Agua Hedionda Creek. This species is presumed to be breeding on-site. Yellow-breasted Chat (Icteria virens auricollis) Listing: USFWS - none CDFG - Species of Special Concern Carlsbad HMP - Covered Species Distribution: Chats are found throughout much of the United States in the summer, but avoid the more arid deserts. This species winters southward to Panama. Habitat: Yellow-breasted Chats nest in riparian woodland and scrub, generally with a dense undergrowth component. They also may be found on the periphery of swamps and freshwater marshlands. Status: Once fairly common in riparian habitats throughout California, chat populations have greatly declined in southern California due to habitat destruction and cowbird parasitism. In recent years, this species also appears to have significantly benefitted from the cowbird trapping programs targeting Least Bell's Vireo breeding areas. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 37 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Study Area: During 2000, two Yellow-breasted Chat territories were identified on the creek in the southern portion of the study area. Southern California Rufous-crowned Sparrow (Aimophila ruficeps canescens\ Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - Covered Species Distribution: This subspecies of Rufous-crowned Sparrow occupies a relatively narrow range of coastal southern California from Santa Barbara County south into Baja California. Habitat: Typical habitat of the Rufous-crowned Sparrow is sparse, low scrub or chaparral, sometimes mixed with grasses and/or rocky slopes. Status: This species is usually present where good quality sage scrub and/or'open chaparral vegetation is present. It is considered an uncommon to fairly common but localized resident in San Diego County (Unitt 1984). Study Area: Rufous-crowned Sparrows are relatively common in both sage scrub and chaparral habitats on-site. San Diego Black-tailed Jackrabbit (Lepus californicus bennettii) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: This subspecies of Jackrabbit occurs from Point Conception-Mount Pinos east/southeast to Pasadena, western Anza-Borrego Desert, Jacumba south to San Quintfn Baja California, Mexico. Habitat: The San Diego Black-tailed Jackrabbit is generally found in open or semi-open vegetation, including grasslands and open sage scrub. Status: This Jackrabbit is believed to be declining. In coastal San Diego County it is primarily found only in relatively large habitat blocks. Project Site: Droppings ofjackrabbits were observed in the more southern portion of the property. The grasslands and areas of open sage scrub offer suitable habitat; however, much of the property is covered by vegetation more dense than that typically occupied by this species. Only a small population is expected on-site. San Diego Desert Woodrat (Neotoma levida intermedia} Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: This subspecies of Desert Woodrat ranges from San Luis Obispo south to San Bernardino Mountains, Redlands, continues south through Julian and Dulzura, and on into Baja California, Mexico to the Sierra San Pedro Matir. A disjunct population also is reported from the Porterville area in Tulare County. Habitat: Various native vegetation types are inhabited by the San Diego Desert Woodrat, including sage scrub, chaparral, and oak woodland. This species is often associated with rock outcrop and cactus patches. Status: Unknown, but believed to be declining due to loss of habitat. Study Area: Stick nests and droppings of woodrats were observed throughout the property. Where such sign was noted in areas of sage scrub and rock outcrop, it is likely indicative of the San Diego Desert Woodrat. Larger stick nests located in oak woodlands and Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 38 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 more mesic environments is more likely due to the similar, but non-sensitive, Dusky- footed Woodrat. Sensitive Wildlife Species Potentially Occurring On-Site Harbison's Dun Skipper (Euphves vestris harbisoni) Listing: USFWS - none CDFG - none, formerly Special Animal Carlsbad HMP - none Distribution: Occurs in scattered, isolated colonies in San Diego and Orange counties. Habitat: Oak riparian. Usually found in moist areas on San Diego Sedge (Carex spissa). Status: Declining. Has a narrow, restricted range within cismontane habitat from Santa Ana Mountains to Tecate Peak. Habitat has experienced declines in recent years due to human encroachment and remaining colonies now consist of small isolated populations. Project Site: This species has moderate potential to occur on-site. Host plant is common in the oak riparian understory. Ouino Checkerspot Butterfly (Euphvdryas editha quinoi) Listing: USFWS - Endangered (Date Listed: January 16, 1997) CDFG - none Carlsbad HMP - none Distribution: Principally found among foothills and coastal mesas of western Riverside and San Diego counties; south to northern Baja California, Mexico. Habitat: Larva utilize native Plantago species, particularly Plantago erecta. Populations may also feed on, and utilize as larval hosts, plants in the family Scrophulariaceae. Status: This subspecies has severely declined from its historic numbers and distribution. Native habitats have been eliminated by development and habitat modification (e.g., increase in non-native grasses) may have made otherwise available habitat unsuitable. The elimination of small, isolated colonies due to these factors adversely affects the entire subspecies through the loss of island patches between larger colonies which serve in dispersal. This also limits the ability to re-establish open patches of nearby habitat. Annual fluctuations in numbers make quantitative assessment difficult, but the limited number of individuals observed over the last decade suggests the that southern California subspecies may be near extinction. Study Area: The study area is outside of the known distribution of Quino Checkerspot, such that focused surveys were not required under the USFWS Year 2000 survey protocol (USFWS 2000). This species is not expected to occur on-site. Primary larval host plant, Dot-seed Plantain, is lightly distributed throughout much of the property, and found in greatest concentrations in pockets of clay soils. Hermes Copper (Lvcaena hermes) Listing: Distribution: Habitat: USFWS - Species of Concern CDFG - none Carlsbad HMP - Covered Species Western San Diego County to northwestern Baja California, Mexico. Colonies are strongly associated with the larval host plant Spiny Redberry (Rhamnus Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 39 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 croced). Adults feed on nectar from Flat-top Buckwheat and other species. Status: Declining. Colonies appear to be stable, but the species now occupies only half of its former range. Fire and development in San Diego County threaten existing and additional colonies. Due to its very limited United States range, this species is believed to have good potential for future federal listing as threatened or endangered. Proj ect Site: The larval host plant, Spiny Redberry, was not documented on-site during the current surveys or past site investigations by Dudek; but may occur in low numbers. Based on the absence or dearth of the host plant, Hermes Copper is not expected on-site. Western Spadefoot (Scaphiopus hammondif) Listing: USFWS - Species of Concern CDFG - Species of Special Concern MSCP - none Distribution: Mostly Central Valley, bordering foothills and Coast Ranges south of San Francisco Bay into northwestern Baja California, Mexico. Habitat: The Western Spadefoot is primarily found in the lowlands (below 3,000 feet), frequenting washes, river floodplains, alluvial fans, playas, alkali flats, and ranges into the foothills and mountains. It appears to prefer sandy or gravelly soil in grasslands, sage scrub, open chaparral, and pine-oak woodlands. Breeding typically occurs in seasonal water pools, including vernal pools and road ruts. Status: Populations are believed to be declining and likely suffering from effects of fragmentation. Project Site: Moderate potential exists for the presence of the Western Spadefoot. Arroyo Toad (Bufo californicus) Listing: USFWS - Endangered (date listed: December 16,1994) CDFG - Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: Coast Range from near Santa Margarita, San Luis Obispo County, south into northwestern Baja California, Mexico; Transverse Mountains. Desert population along Mojave River in San Bernardino County. Habitat: Found in washes, streams and arroyos in semi-arid lowlands. Prefers sandy banks with willows, cottonwoods, or sycamores. Status: Not well known; appears to be uncommon with a spotty distribution; much of its former habitat, sandy river floodplains, has been disturbed. South of Ventura, only a dozen or so extant populations have been recently documented. The expansion of non-native, predatory Bullfrogs is a possible factor in the decline of Arroyo Toads. Study Area: Arroyo Toads are not expected within the study area. The more southerly of the two on-site drainages lacks sandy substrate and relatively open conditions favored by this species, and the intermittent creek appears to be primarily supported by urban run-off. Agua Hedionda Creek is not known to support this species and the on-site segment is disturbed by illegal immigrant encampments and rural land uses. A dense canopy of Coast Live Oak overlaps the lower riparian segment of the study area, and this species typically prefers a relatively open canopy near its breeding habitat. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 40 Merkel & Associates, Inc. # 97-104-06 December I, 2000 Southwestern Pond Turtle (Clemmys marmorata pallida} Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: This subspecies, C. m. pallida, occurs from the Monterey area south into Baja California, Mexico. Habitat: Highly aquatic, prefers ponds, creek pools, and marshes with rocky or muddy bottoms. Status: Declining. In southern California, i.e., Los Angeles County south, this turtle is becoming quite rare due to the general destruction of lowland riparian areas and human disturbance. The expansion of non-native, predatory fish and Bullfrogs are additional probable factors in the decline of Southwestern Pond Turtles. Study Area: This species is given low potential for on-site presence. The riparian areas offer only marginal habitat due to the lack of suitable plunge pools and basking sites. Coronado Skink (Eumeces skiltonianus interparietalis) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: This subspecies of Western Skink has a very limited range within the United States. It occurs in coastal San Diego and Orange counties and into the Los Angeles region, as well as northwest Baja California, Mexico including the Coronado Islands. Habitat: Coronado Skinks occupy many habitat types including grasslands, sage scrub, chaparral, oak and pine woodlands; however, they are difficult to detect except beneath debris or leaf litter following rain events. Status: The Coronado Skink has a limited range and much of its coastal habitat has been developed for urban uses. Nevertheless, it is still believed to be common where suitable habitat persists. Project Site: Coronado Skinks are expected to be present in low to moderate numbers on-site, based on the availability of suitable habitat (sage scrub, chaparral, grassland, woodlands). Coastal (Western) Whiptail (Cnemidophorus tigris multiscutatus) Listing: USFWS - Special Concern Species CDFG - none MSCP - none Distribution: This subspecies is found from Santa Barbara County southward through the northern two-thirds of Baja California, Mexico. Habitat: Semi-open areas and sunny microhabitats in sage scrub, chaparral, open woodlands, peripheral edges of riparian zones and washes, as well as desert and other arid habitats are all utilized by this whiptail. Status: This species is relatively common in areas where good habitat occurs; however, vast areas of former habitat in the coastal lowlands have been converted to urban and agricultural development. Project Site: The Coastal Whiptail is not documented from the study area, and is generally more common at more xeric, inland locations, often where there is a more sparse coverage of shrubs. If present on-site, only a small population of Coastal Whiptails is expected. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 41 Merkel & Associates, Inc. # 97-104-06 December I, 2000 Silver/ Legless Lizard (Anniellapulchra) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: This legless lizard ranges along coastal California from San Francisco south to northern Baja California. Habitat: This nocturnal lizard is seldom seen on the surface. It shows a preference for areas of leaf litter and loose soil along washes, beach sand dunes, open scrub and woodland, and sandy benches along alluvial fans. Status: The status of the Legless Lizard is poorly understood, but believed to be declining due to habitat loss. , Study Area: Areas near and along drainages, offering loose soils and/or oak leaf litter, provide good potential habitat for the Legless Lizard. It is given a good potential for occurrence within the study area. Two-striped Garter Snake (Thamnophis hammondii] Listing: USFWS - none CDFG - Species of Special Concern, Protected MSCP - none Distribution: This garter snake ranges north as far as the Carmel Valley, then into the South Coast Ranges west of the San Joaquin Valley, further south to the Peninsular Range and the southern California coast, and into Baja California, Mexico. Habitat: Although aquatic habitats (creeks, rivers, freshwater marshes, and vernal pools) are the typical habitat, this species is occasionally found in peripheral upland habitats such as chaparral, sage scrub, and woodlands. Status: Once common in southern California; at present, this garter snake is declining due to wetland habitat disturbance. Predation of young snakes by Bullfrogs and non- native fish (e.g., Largemouth Bass) may also affect population levels. Study Area: Two-striped Garter Snakes are given good overall potential to occur on-site; however, only a small population is expected. Ferruginous Hawk (Buteo regalis) Listing: USFWS - Species of Concern CDFG - Species of Special Concern MSCP - Covered Species Distribution: Western United States Habitat: The Ferruginous Hawk is associated with large expanses of grassland or agricultural fields. Status: Declining. This species is an uncommon but regular winter visitor to mountain areas and coastal fields. Study Area: The Ferruginous Hawk has low potential to occur as a migrant or winter visitor to the site. This is an uncommon species in urbanizing coastal areas, and is usually found in much more extensive tracts of grassland or open fields. Golden Eagle (Aquila chrysaetos) Listing: USFWS - protected under the Bald Eagle Act (1940) CDFG - Species of Special Concern, Fully Protected Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 42 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: Golden Eagles range throughout the western United States and southern Canada. Habitat: Golden Eagles typically nest in tall, rugged, inaccessible cliff habitat and sometimes in tall trees. Foraging habitat consists of extensive tracts of undeveloped land in the vicinity of nest sites. Status: Once a common breeding bird, the Golden Eagle population has greatly declined due to loss of, and disturbance at, nest sites in southern California, particularly San Diego County. Urban encroachment and loss of foraging habitat are additional probable factors in the decline of this species. Study Area: Recon (1984) recorded an eagle observation the north-central portion of the study area, which is probably the same site record as in the regional database for the Carlsbad HMP. No eagle nesting habitat occurs on-site, and the'closest known Golden Eagle breeding territory is near Lake Hodges/Mt. Israel, approximately eight miles to the east. Golden Eagles are known to forage over very wide ranges, but it is unlikely that a foraging territory would regularly extend this far westward due to the intervening urban development. Much of this development has occurred in the past 10 years. The site is not expected to provide important habitat to Golden Eagles, but there is low potential that the site would be used by a dispersing individual or during migration. Prairie Falcon (Falco mexicanus} Listing: USFWS - none CDFG - Species of Special Concern MSCP - none Distribution: The Prairie Falcon occurs throughout the western United States. It is an uncommon winter visitor to southern California and a rare breeding resident in San Diego County. It winters southward into northern Mexico. Approximately twenty nest sites are known for this falcon in San Diego County, but this species sometimes has weak nest tenacity. Most nests are concentrated in the desert, but a limited population reportedly still breeds on the coastal slope (Unitt 1984). Habitat: Prairie Falcons are typically seen in open, arid country such as grasslands, deserts, and interior valleys supporting agricultural and fallow fields. During the winter it may also be found foraging near mudflats and extensive fields near the coast. Status: This species is extremely rare as a breeding species in southern California, but collection records indicate this falcon was never common in the area, even prior to widespread urban development. The coastal population is nearly extirpated. Project Site: Prairie Falcons could occur on-site as migrants, but significant use of the property by this species is not expected. Southwestern Willow Flycatcher (Empidonax traillii extimus) Listing: USFWS - Endangered (Date listed: February 27, 1995) CDFG - Endangered (Date listed: January 3, 1991) Distribution: Southwest United States and northwest Mexico. Habitat: Summer resident only. This subspecies typically breeds in willow riparian woodland, but Coast Live Oak riparian woodland is used along the San Luis Rey River. Status: Seriously declining subspecies. Study Area: Tape recordings of the Southwestern Willow Flycatcher were played in suitable habitat during the focused Least Bell's Vireo surveys. One individual responded to Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 43 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 the tape on May 23, 2000; however, no individuals were detected during the remainder of the season. The observed individual is therefore assumed to have been a migrant. Due to its migratory status, the observed Willow Flycatcher could belong to another of the willow flycatcher subspecies which are known to migrate through the region. That is, the observation cannot conclude that the observed bird was the state and federally listed subspecies (E.t. extimus). Loggerhead Shrike (Lanius ludovicianus) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: Occurs throughout the United States, south-central Canada and northern Mexico. The northern populations are migratory. Habitat: Typical habitat is open country with scattered trees or other perch sites. Status: The Loggerhead Shrike is continuing to decline throughout its range (Graham 1990). Resident populations are augmented by an influx of wintering individuals. Project Site: The grassland areas and agricultural fields offer suitable foraging habitat, but this species has not been reported on the property. It is given a high potential to occur on- site at some point in the future. Tricolored Blackbird (Agelaius tricolor} Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: The Tricolored Blackbird is endemic to California and a small area of extreme southern Oregon. Habitat: This species typically breeds in large colonies in extensive freshwater marshes. During the non-breeding months it is somewhat nomadic and forages widely in cultivated fields and variable open habitats. Status: Tricolored Blackbirds are believed to be declining due to habitat loss, particularly in the Central Valley. This species was proposed for State Endangered status but was rejected. Study Area: Moderate potential exists for the Tricolored Blackbird to breed in the cat-tail marsh in the south/central part of the study area, or in the marsh surrounding the small pond. Bell's Sage Sparrow (Amphispiza belli belli} Listing: USFWS - former Species of Concern CDFG - former Species of Special Concern Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: Bell's Sage Sparrow has been treated as a distinct species (Amphispiza belli) from the more widespread Sage Sparrow (Amphispiza nevadensis) (Rising 1996). It ranges from Trinity County along the coastal slope southward to northwestern Baja California, Mexico. Habitat: Bell's Sage Sparrow is resident in both sage scrub and chaparral vegetation, but is _ generally found only in large habitat blocks. Status: Bell's Sage Sparrow is believed to be declining due to habitat loss throughout its California range, particularly in coastal southern California. Preliminary findings Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 44 Merkel & Associates, Inc. # 97-104-06 December I, 2000 from the San Diego Breeding Bird Atlas indicate that this species has not persisted well in areas fragmented by development (Phil Unitt, personal communication). Project Site: Bell's Sage Sparrow was not observed or heard calling on-site, and was not documented during other investigations overlapping the study area. The sage scrub and chamise-dominated areas on-site offer suitable habitat for this species. It is given a low potential for occurrence. Grasshopper Sparrow (Ammodramus savannarum) Listing: USFWS - none CDFG - none Carlsbad HMP - none Audubon Blue List (Tate 1986) Local-Everett(1979) Distribution: North America, Central America, and parts of South America in grasslands. Habitat: This species uses both native and non-native grasslands with scattered shrubs. Status: This is an uncommon breeding species in southern California with highly localized population. Project Site: Grasshopper Sparrows were not detected on the property. Low-to-moderate potential exists for this species to occur on-site, with the more suitable habitat being the grasslands at the southern end of the study area. Pallid Bat (Antrozouspallidus} Listing: USFWS - none CDFG - Species of Special Concern MSCP - none Distribution: Found throughout California with the exception of the northwest portion of the state and the higher elevations of the Sierra Nevada Mountains above 6000 feet. Habitat: Occupies a variety of habitats. These relatively large bats typically feed on large terrestrial arthropods. The coastal subspecies prefers grassland and oak woodlands for foraging. Roosting may occur in crevices in trees, rocks, and buildings. Status: Pallid Bats are believed to be declining, possibly due to disturbance/loss of roost sites and/or the loss of foraging habitat. Project Site: Suitable roosting habitat is quite limited on-site, but there is some potential for this species to use the very mature oaks in the downstream portion of the study area. This species has a moderate potential to forage on-site. Pacific Pocket Mouse (Perognathus longimembris pacificus) Listing: USFWS - Endangered CDFG - Species of Special Concern Distribution: Restricted to the coastal strip of southern California from the vicinity of the U.S./Mexico border northward to El Segundo, Los Angeles County (Williams 1986). Habitat: Areas of fine, sandy substrate. Status: Declining. Presumably has suffered considerable amounts of habitat loss due to urbanization of coastal areas. Project Site: Present and historically occupied habitat of the Pacific Pocket Mouse occur within approximately 4-5 kilometers of the coast. The study area exceeds this distance, and generally does not exhibit the characteristic habitat and sandy soils occupied by this species. This species is not expected to occur on-site. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 45 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Northwestern San Diego Pocket Mouse (Chaetodipus fallax fallax) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: This subspecies is reported to occur from San Onofre north to Claremont, northeast to Banning, then south to Jacumba and on into Baja California to San Quintin, Mexico. Habitat: Habitats occupied by the San Diego Pocket Mouse include sage scrub, chaparral, and oak woodland. Status: Due to extensive urban and agricultural development, this species has presumably suffered a considerable loss of occupied habitat. However, small mammal trapping studies routinely capture this species within suitable habitat. Project Site: The San Diego Pocket Mouse is expected to be common in the sage scrub, oak woodlands, and possibly chaparral habitat on-site. Dulzura California Pocket Mouse (Chaetodipus californicus femoralis) Listing: USFWS - Species of Concern CDFG - Species of Special Concern Carlsbad HMP - none Distribution: Coastal southern California from the north of the Santa Margarita River, north to Temecula, south to Aguanga, Dulzura, and on into Baja California, Mexico. Habitat: This species is most commonly associated with chaparral and oak woodland habitats Status: Due to extensive urban and agricultural development, this species has presumably suffered a considerable loss of occupied habitat. Small mammal trapping studies routinely capture this species within suitable habitat. Project Site: The California Pocket Mouse is given moderate potential to occur on-site, with most likely areas of habitation being the chaparral habitats. American Badger (Taxidea taxus) Listing: USFWS - none CDFG - Species Animal Carlsbad HMP - none Distribution: From Alberta and Saskatchewan, Canada, southward through central and western United States and into Baja California and central Mexico. In California, Badgers occur throughout the State except in the northwestern corner. Areas of greatest abundance are in the northeastern region and along the south central coast area with moderate populations occurring in the southeastern desert areas, eastern southern Sierra Nevada, and southern San Joaquin Valley. Habitat: Found in grasslands, open scrub, and mountain meadow habitats with friable soils. Status: Current status unknown but the species has experienced drastic declines in California within the last century. Agriculture and urban developments have been the primary causes of decline and extirpation of populations in California. Project Site: The better suited habitat (i.e., grassland) for Badgers primarily occurs in the more southern portions of the study area. These areas are often more disturbed and receive highly levels of human use (biking, etc.). No evidence or recent historic sightings have been documented on the property. It is given a low potential for occurrence to be resident in the study area. Faraday Avenue Extension, Agua Hedionda Sewer, and Carlsbad Oaks North Business Park 46 Merkel & Associates, Inc. # 97-104-06 December 1, 2000 Mule Deer (Odocoileus hemionus} Listing: USFWS - none CDFG - none Carlsbad HMP - Not presently covered, but may be added under the MHCP Distribution: Mule Deer occur throughout California. Habitat: Mule Deer use a wide variety of habitat types including sage scrub, chaparral, riparian, grassland, and woodlands. During daylight hours, Mule Deer are more inclined to remain in dense vegetation such as chaparral, taller sage scrub, or wooded areas, but at night this species can be found foraging in more open habitats. Status: Mule Deer are common in San Diego County, but their numbers along the coast have been significantly reduced due to habitat conversion for agriculture and urban development. Study Area: Mule Deer sign was not observed on-site, and this species has apparently been absent from the adjacent University of California reserve property (adjacent to the north) for many years (Isabel Kay, U.C. Reserve, personal communication). On-site vegetation quality appears highly suited to Mule Deer, but direct and indirect effects of human/urban encroachment (e.g., illegal immigrant encampments) may make the site unsuitable.

FEDERALLY LISTED AND CANDIDATE SPECIES FE Federal Endangered Species FT Federal Threatened Species FC FSC Federal Candidate Species Federal Special Concern Species FPE Federal Proposed Endangered FPT Federal Proposed Threatened Listed as Endangered by the federal government under the Endangered Species Act of 1973. Taxa that are in danger of becoming extinct throughout all or a significant portion of their range. Listed as Threatened by the federal government under the Endangered Species Act of 1973. Taxa which are likely to become Endangered in the foreseeable future in the absence of special protection. Taxa for which the USFWS has sufficient biological information to support a proposal to list as endangered or threatened. Applies to taxa for which information may exist to possibly support listing, but for which substantial biological information is lacking to support a proposed rule. Taxa which have been officially proposed for federal endangered status, but the biological information to make such a determination is currently under review. Taxa which have been officially proposed for federal endangered status, but the biological information to make such a determination is currently under review. CALIFORNIA LISTED AND CANDIDATE SPECIES CE CT CP California Endangered Species California Threatened Species A native California taxa which is in serious danger of becoming extinct throughout all or a significant portion of its range (Fish & Game Code 2062). A native California taxa which, although not presently threatened with extinction, is likely to become an endangered species in the foreseeable future in the absence of special protection and management efforts (Fish & Game Code 2067). California Fully Protected Species Taxa which fall under special protection within the Merkel & Associates # 97-106-06 A-3 - 1 Faraday Avenue Extension, Agua Hedionda Trunk Sewer, Carlsbad Oaks North December 26, 2000 CSA California Special Animals CSC CDFG Species of Special Concern Fish & Game Codes (3511,3700,4800,4900,5000, 5050,5515). Taxa listed as Special Animals fall into one or more of the following categories: • Taxa that are biologically rare, very restricted in distribution, or declining throughout their range. • Population(s) in California that may be peripheral to the major portion of a taxon's range, but which are /threatened with extirpation within California. • Taxa closely associated with a habitat that is declining in California rapidly (e.g., wetlands, riparian, old growth forests). Taxa for which sufficient information exists which warrants concern over that species status and may warrant future listing as threatened or endangered. Protective status falls under State Government Code 66474. CALIFORNIA NATIVE PLANT SOCIETY R-E-D CODE R (Rarity) 1 2 3 Rare, but found in sufficient numbers and distributed widely enough that the potential for extinction of extirpation is low at this time. Occurrence confined to several populations or to one extended population. Occurrence limited to one or a few highly restricted populations, or present in such small numbers that it is seldom reported. E (Endangerment) 1 Not endangered. 2 Endangered in a portion of its range. 3 Endangered throughout its range. D (Distribution) 1 More or less widespread outside of California. 2 Rare outside California. 3 Endemic to California. List IB: Plants rare, threatened, or endangered in California or elsewhere List 2: Plants rare or endangered in California, but more common elsewhere. List 3: Plants about which more information is needed. List 4: Plants of limited distribution. A "?" under Rarity/Endangerment/Distribution is given when information to allocate a code is incomplete. NATIONAL AND INTERNATIONAL SENSITIVITY LISTINGS Merkel & Associates # 97-106-06 A-3 - 2 Faraday Avenue Extension, Agua Hedionda Trunk Sewer, Carlsbad Oaks North December 26, 2000 BL Audubon Society Blue List (Tate 1986) National listing of species which are showing patterns of decline over all or part of their natural range. CITES Convention on International Trade in Endangered Species of Wildlife Fauna and Flora (1976) IUCN International Union for the Conservation of Nature and Natural Resources LOCAL SENSITIVITY LISTINGS (SAN DEEGO COUNTY) SDKS San Diego Herpetological Society (1980) Threatened Species or subspecies which have dramatically declined and could potentially reach the level of endangered in San Diego County. Endangered Species which are in immediate danger of extirpation in all or major parts of their range in San Diego County. SDNGWS San Diego Non-Game Wildlife Subcommittee (1986) Sensitive Species Species warranting special concern and protection and may be recommended for further study. Ev Everett (1979) Threatened Declining Sensitive Considered sensitive in San Diego County. A species or subspecies which has undergone dramatic, non-cyclic, long-term population declines, to the point where the situation has reached the critical level throughout their range. Many of these species have been recognized and protected by state or federal legislation. A species whose local breeding populations have been steadily reduced, or in some cases extirpated. A species for which declines have not been documented, but are regarded as sensitive because of: 1) extremely localized or limited distribution, 2) sensitivity to disturbance, 3) actual or impending destruction of essential habitat, or 4) lack of sufficient data on current or past status which significantly increased the potential for serious reduction of a local population.
