(ACT,' Inc'.,) conducted a-survey of a rectangularly shaped, eighty acre parcel known as Sea Pines'. The: propertly is located fn the northeast one qua,rtet of Section 28; Townsbip 12 South, Range 4 West, San Be'rnardlno, Base and' Me~idian (Figures 1 and 2). Although exact Site plans are hot yeu~Qmpleted it is known that the projeCt will conaistof residential dwelling uni ts and all the' necessary streets, fot circulatlion. Tne res.u.lts of the survey were positive. A, small srhell and lithic' tool scatte'r was loc'ated as' well as evidence of rec~nt farming acti vi ties. These results wi 11 be discuss,ed in Section III ot tbis report. A. LoC_tion and Topographic Se~ting, Tbe subject property City of Carlsbad, California. is located within boundaries of the It is situated approximat~ly Z,500 feet ea-st o~ the intersection of Poinsetria &ane and Interst~te 5 and one and one-half miles north of Batiquitos Lagoon., TpeSea Pines property is bounded on the north and east by agricu11;ural land on the south by a residential development and on the west Qy relatively unaltered land. Topographically the project is located on t.he west,ern ,slopes -2- o·f a generally north/south trending rfdg,e. The property. slop~:s from east to west with elevations ranging from ~ high of 22m fe~~ above mean seal level (amsl) to a. low of 115 fee-t amsl. Sea- Pines is heavily dissected by six east/west erosiori gullies. The-se gull ies ~re generally wide, 100 .to 20:0 feet across, w-i 1;:h . relatively ste~p sides. ~ou.twest. corner. The Th~ greatest erosion actiVity is in' pattern. of erosion. m~y have the been facilitated by agricultura~ activities which took place' on the property in the past. B. Soils soils on the Sea Pines property are made. up of two types; the Che$-terton Series and the Rug:ged Broken Land Series (Figure 3). These are defined by Bowma-n (1973) as· fo.llows.: Chest.erton Series: This soil consists ofmode.rate.ly well draine'd sandy loams that have a sandy sub-soil. They have formed in pl~ce by the weathering of the unde.rlying sandst·one. The color ranges from brown (10YR 5/3 Munsell color) to very pale brown (10YR 7/4). Rugged Broken Land Series: This soil consist.s wel1-drained to excessively drained, steep and very ateep land dissected by many V-shaped valleys. c. Vegetation The flora noted during the study of the subject property -3- consists of plants typical of distu-rbe.d or disrupted are_a~ Th'e vegetation is made up of primarily of thick s~ands of mustard. (Bra-ssica sp.), dense grasses (Bromas sp.), and f.oxtails (Ho.rdeum .sp)~ Sqme native vegetation is present around' the edges of the gulli.es and in the southwest corner of th'e propert;y.

The -parc,e1 was walked by means of a series of cont~olled north/sout~ and e~st/wesr transects (see Figure 4). The work was begun ih,ths northwest corner of the parcel and comp1et-ed. -i,n the flo-r-tihwe,st _ co'roer. Much of. the study was concen.t-rated on the non-er.oded· portions of the Sea Pines project. Wi t.h the amount of-erosion having. ta'ken place in the gullies it 1.s unl ike1¥ that. ¢xtant ~ultural resources would be fouhd there. The survey was made difficult by, two factors; one the vegetat:ion and, two the farming which had taken __ pla,ce in the past., The visibili ty of the ground ranged f_rom fa!.r to poo·r., Artifacts and features could be noticeable -upon close inspection. Plowing was evidenced, through the presence of furrows·. Some of these measured ane foot to two feet wide and one-half foot to nearly two feet deep. A scatter of shell and stone was noted in t'he sou,theast . one quater of the property. No cultural materials we're noted on the rest of the parcel. -11- B. Fir:ldings A s~ngle archaeological site was located during the co~rse of the project. It had previously had been recor'de,d as 8Di-675-0·. a'nd W-1873. The si te is located in the southeast'ern portion of the 8ea Pines property. It is situated on the side af a sm~ll knoll ju:st north of the grave'l access roa'd. Ttie elevati.on is app,roxlmat'ely 190 feet. The long axis measures apprQ}!:lmately 60, • meter$ northeast/southwest and the transvers'e, ax'i.s ine,a'sures appro'x-imc;ttely 20 meters northwest!southeas·t.. T,hese meaSure,ments may well be erroneous, the result of smearing by long years 'o,f plowing,. The pattern of plowing seems to have been pI? and down the, ridges rather than across. This' coupled w,i th erosi.ori· through iun-off:may have resulted in a displac::ement' of the su:rfac:e manifestations of the site." It se,ems 11k.ely that t'he site' was .~uch smaller in the past. The soil on the site is a very pa,le brown sandy loam. Based upon t'he exposure in the a~cess road cut it has a depth of about. one-half to one meter~ If there had been a s~ained midden at 8D'i-6750 the color has leached out 'of the soil., The' vegetation at' ,the site consists of primarily mustard. and s'ho,rc gr~asseS., The site is made up of a light scat.ter of chione and pect,in shell along with approximately 10 fractured stone items. , The$e stories appear to be fragments of manoS and flakes. 1he stone does nota.ppear to be totally contiguous with the shell, in th'at the s'hell has a wider areal 'distribution. -12- It is difficult to place cUltural affiliation on a site $uch as SD i-6750. However, based upon previouse~per ience the si t-e is tentatively designated as Early Archaic Stage, La Jolla Aspe:ct_ •. C. Sighifi~ahce of the Findings "The concept of significance like no· o'ther in conservation. archaeology is a constant source of frustration and inspiration" {Schiffe·r and Gummerman 1979:239l. Th.e conc~pt. of. si,gnif.icance as appl.ied t·.O an archaeological si te ref~r$ to the assessment of value the resource contains to cititens of th~ State of California and of the United States~ Sites. tt i. '~enerally appraised in terms of scientific and cultural values. The. site located on the Sea Pines property a:ppea'r to ·be a·n ephemerally used campsite. Cortsidering the numb~rs of shell present it may have only been used once or twice. Thi$ is of. c.ourse conjectu~e based soley upon surface evidence. The: sit~ may well be part a system of si tes which are 10cateQ t6 th·e south, east and north. The scientific va.Iue of· the mater:i.als may be diminished by their havinq been impacted by plowing~ Th~ field inspection of the site would tend to· place the level of impacts as severe. This judgement may be modif.ied based upon any future tes·ting program. At the pres~nt time and based upon the evidence at hand SDi-6750 appears to· have the poten.tlal t·o answer only limited scientific questions. -13- IV. IMPACTS RESULTING FROM IMPLEMENTATION OF THE PROPOSED ACTION The construction of dwelling units and roads on the Sea Pines property may result in the loss of the site SDi-6750 as described in Section III. V. MITIGATING MEASURES There are two basic ways of mitigating impacts to a cultural resource. These include preservation or data salvage. Due to the heavily impacted condition of the site, these actions may not be required, therefore we are recommending that the level of disturbance be verified. The following actions are recommen~ed~ 1) Determine the extend of the shell scatter. 2) Collect the shell and stone artifacts. 3) Excavate one 1.5 meter by 1.5 meter test unit. 4) Catalog all recovered materials. 6) Prepare an addendum to the survey report which describes the findings. -14- VI, Sources Chace, P 1981 An· Archaeological and Paleontologic'al Su-rvey of the Oce':iden'tal Land Inc." properties.

The purpose of our -observations were t6 form. ' an opinion as to the nature of the geologic materials. making up the bl~ff and to obtain a sample for testing in the laboratory. Our observations indicate this near-vertical bluff is composed of a red-brown Pleistocene terrace deposits which consists of moderately well-cemented, medium:-to fine-grained sandstone. Laboratory tests indicate that this sandstone is cemented primarily by clay minerals. Upon exposure to water, this 'material rapidly disintegrates to form a slurry of fine clay particles, Silt, and sand. It is therefore our opinion that erosion of this material during heavy precipitation could result in siltation of nearby street or building pad improvements. If 'you have any. questions concerning this matter, please do not hesitate to give me a call at your convenience. Very truly yours, ~~D M~chael W.

These lots begin at Batiquitos Lane and run easterly on Daisy Avenue. 2. There are essentially no willows behind these lots. 3. Commercial traffic to Thompson Rose Nursery on temporary easement 20, to 100 feet north of rear yards. Traffic is fairly frequent and undesirable. '4. Due to ease of access from Batiquitos Lane and easement, vaCant ground north of rear yards is used,for illegal dumping by public. Some trash dumping over 6 foot rear Spinnaker Hill fences by some homeowners is obvious. 5. Rear property lines are approximately 5 feet south of existing fence. 6. Rear yards are lower than the top of existing fence(i.e."no view, from yard) - Lot 1 Lot 2 Lot 3 Lot 4 14 'feet 9 feet 7 feet 7 feet SPINNAKER HILL LOTS 5, 6, 7, 8 2 9, 10 i. Willows are approximately 60' to 120' north of rear fence. 2. Rear property lines are at bottom of rear 6'to 7 foot high slope. Rear property lines are 6 to 12 feet south of rear fence. 3. Rear yards are very low in relationship to top of rear fence due t~ high bank which is owned by Standard Pacific (i.e., no view from yard) Lot 5 -12 feet lower Lot 6 13 feet lower Lot 7 13 feet lower Lot 8 13 feet lower Lot 9 13 feet lower Lot 10 -12 feet lower 4. By walking the fence line behind the Spinnaker Hill lots, it would appear the willows generally cannot be seen from the rear yards. 5. It also appears that two-story homes built approximately on existing grade in Sea Pines typically could not be seen from Spinnaker Hill rear yards. -2- SPINNAKER HILL LOTS 11, 12 aild 13 1. v1i11ows have grown to within 10' to 15' of rear fence. 2. .Rear fence is within few feet of existing grade. 3. . ,OJ;le Spinnaker homeowner has cut willows back apparently due to fire hazard they present. 4. If willows were. cut back to 50' from wood fe~ce, approximately half of the willows in this area would be removed. Regrowth would be a problem. 5. Acacia. longifo1ia planted now on Standard Pacific's property north of fence would achieve a 12-foot height within two years well in advanc~ of occupancy of Sea Pines homes. 6. The willows are a fire hazard behind lots 11, 12 and 13. Acacia would not be. 7. During the last several years, the willows have often been used by illegal aliens as a temporary campsite. It is probably not desirable to have an area attractive to illega1s close to single-family residences. Numerous rat nests are also evident in the willows. i I' " . •• 11-18-82 SEA PINES YARDAGE COMPARISONS . TOTAL .. TOTAL TOTAL C.Y.! C.Y.! D .• U~'s ACRES C.Y. D.U.

Willows are not drought resistant b. Willows are flourishing due to da;i1y concentrated supply of fertilized runoff water; would partially or fully die out if water supply is cut back or terminated c. Primary root systems are in sandstorre. Alluvial material is normally associated with willows in natural drainag.e cours'es. A1;t.uv'ium holds water, sandstone does not, d. Willows are dependent on one greenhouse business for their wat~r. e. Days are numbered for greenhouse businesses in area, many have gone out of business 1. Escalating energy costs 2. Escalating labor costs 3. Escalating water costs 4. Competition from areas not impacted by local costs -2- 4. Should homeowners association be required to maintain willows in present condition(in spite of water conservation measures being adopted by govern- ment agencies)if water supply is terminated? - a. Will future water costs be prohibitively expensive?, 1. Current water requirement of willows is estimated at $4,700/year 2. City estimates 400% water cost.increase within eight years, i.e., to $20,000+ for willow irrigation 3. City estimates 1600% water cost increase within the following ten years, i.e., to $80,000 for willow irrigation. b. Would Sea Pines homeowners iesist a substantial increase in their fees to water willows? c. Would it be prac,tical for City to enforce a condition ,that Association irrigate trees? d. Would Sea pjnes homeowners want to pay for picking up trash and general maintenance for an area more associated with Spinnaker Hill than Sea Pine~? '5. Attractive area or attractive nuisance? a. Dense shrub like growth vs. more desirable oak and sycamore areas in Carlsbad b. With higher number of children in area dense growth ,could provide a major supervision problem c. Standing water creates potential liability for property owner d. Trees very inviting to kids to cook out, dam up ~d play in water, etc. -during dry season, trees WQuld be -fire hazard. l • SEA PINES SITE SENSITIVE ISSUES AT SPINNAKER HILL BOUNDARY Patip homes are compatible with Spinnaker. They are more compatible than the duplexes proposed under the old tentative map. Townhomes are t9 be located 'north of Poinsettia Lane and only patio homes will be south of Poinsettia. This is done to provide a logical transition of housing types in the neighborhood. The proposed plan is sensitive to the existing topography adjacent to Spinnaker. The street and lots are at daylight (see map) with the natural terrain. ~ The plan is sensitive to the visual privacy of the Spinnaker homes because the existing"-fence and slope which typically provide 100% visual privacy, will remain. The immediate planting. (within 30 days) of acacia trees behind the Spinnaker fences will, by the time people move into the new Sea·Pines homes, provide a better visual buffer and sense of privacy than the willows. The plan proposes deep backyards for those patio homes abutting Spinnaker; Hill, yards that are both deeper than the standard Sea Pines yard and the typical abutting Spinnaker rear yard. Standard Pacific plans to meet with Spinnaker homeowners prior to submi~tal of the tentative map to the City in order to explain the development plan for their immediate area and cross sections.

Introduction The Sea Pines Parcel, an eighty acre parcel 'located in .the City of Carlsbad (figure 1), was first studied in'May of 1982 by Archaeological Consulting and Technology (~CT) in orqer to determine the presence/absence of cultural resource materials. The results of this survey were positive in that one shell and lithic scatter was noted in the southeast corner of the property (Berryman 1982). Mitigating recommendations cited in the 1982 report called out for some type of ,subsurface .. testing. A significance test was conducted in May of 19:8:3 by staff members from TerraMar International, (TMI) and will be detailed in this report. Results of the current studY indi.,.. cated that the site is no longer a viable resource and that no further testing be required 0 A. Location and Topographic Setting Sea Pines is an eighty acre parcel located in the northea~t one-quarter of Section 28, Townsl:ip 12, South, 'Range 4 West" of ' the San Bernardino Base and Meridi~n Quadran~ (figure 21.

Topographically, the project is located on the western slopes of a generally north/south trending ridge. The prope~ty slopes from east to west with elevation ranging from a high, of 220 feet above mean sea level (amsl) to a low of l15feet~. Sea·· Pines. is heavily dissected by at least six east/west erosion gUllies. These gullies are approximately 100 t6 200f.eet a'¢ross" with relatively steep sides. The greateste~osion activity is in the southwest corner. The pattern of erosion may have been facilitated by agricultural activities which tookplac~ on the property in the paste B. Soils Recorded soils on the Sea Pines property are made up of two. types,: the Chesterton Series and the Rugged Broken Land Series (figure 3) .• These are defined by Bowman (1.973) as:'-' '. Chesteron Series: soil consists of moderately well, drained sandy loams that have a sandy sub-soil. They have-' been formed in placed by the wea,thering of, und~:t;.lying·· ..... sandstonee Color ranges from ~rown. (lOYR 5/3) to·a ' very pale bro_wn {lOYR 7/4) _ . . . . -' ... ,. .... . ". Rugged Broken Land Series: soil consists.of well-drained to' excessively drained, steep and very s·teep land dissected by mand v-shaped valleys.' C. Vegetation The flora noted during the 1982 survey consisted of plants' typical of disturbed or disrupted atea .. Vegetatio~ patterns' noted during the 1983 study were the same" wit-h ·thi.ck stands of mustard. dense grasses and fQxtails. Some nati~e vegetatiOn· is present around the edge~ of the gullies and in the southwest corner of the property. These plants would include sumac -3:- (Rhus sp~), buckwheat (Eriogonum fasciculatum) I and small stands of chamise (Adenstoma fasciculatum.).Genera].lyl' it can be said that the vegetation is highly disturbed and varied from extremely dense to moderately dense'. ' The level of weeds (foxtails, grasses, e'tc.) on the parcel prohibited are-survey of the parcel. De Fauna Fauna noted during the 1982 survey included jackrabbits (Lepus californicus), doves (Zenaidura macroura), quail (Lophortyr gambeli), hawk (Butea sp.) and a coyote (Canis latrans), via scato No fauna was noted during ·the significance testing of the property. -4- •• j. • SOILS MAP T.rr ••• r Internatl.Qnal.SRYlc •• Ille. 1MI Figure 3 -5-·· II. Background As the 1982 report listed, a number of shell midden u small " campsites and lithic scatters are recorded for the general area around Batiquitos Lagoon. 'Most of these sites' corl:tain some degree of shell and represent past use of the 'lagoon resources. One site, W-1873, was recorded as being 'on the Sea Pines property (see record search p appendix} .. , rrhis site was described as a shell midden, located just north of a di,rt road that connects the greenhouses and Batiqui tos , ' Drive. Approximate measurements were given as 75 x, 60 meters;, with site size expanded via erosional activities_, It was this site that was described within the 1982 ACT report. The 1982 survey stated that W-1873: n was situated on the sj~de of a small knoll just north of the gravel access road" (Berryman . , 1982:ll).1t The site was described as being approxiInately 60 meters northeast/s'outhwest, by 20 meters northjlest!southea,st.' These measurements were considered erroneous, because of past site smearing (via farming) and erosic:>ncil activities.'" The pattern of plowi~g noted'during the 1982 'study indicated that furrows occured up and down the ridges, rather than across-' thus increasing the overall, displacement of artifacts/shel.l. Soils within the site matrix were described as :a.:very p~le brown sandy loam, approximately 1/2 to' 01:le m'e'ter dee:p. "'S.ite,, matrix consisted of a light scatter of chione, and pectin, with approximately 5-10 fractured stone items~ -6- '. III. Fieldwork A significance test was carried out on the Sea Pines Pr-operty on May 20th, 1983. The testing 'program involved: 1) relocating the shell scattered 2) flagging areas of artifact/shell con'centration '. 3) surface inspection of the entire site area 4) excavation of a single 1 x 1 meter unit to sterile sub- soil 5) excavation of radially placed post~ole series 6) analysis of recovered cultural materials As 'stated in the introduction, this' testing program. was carried· out to determine cultural integrity.and to' .define vertical and hortizontal depth. . _. ~ Twenty':'"'three posthole units were placed in areas of heavies·t shell concentration. Each unit was manually excavated t~ the sterile sandstone base and tested for cultural ~aterials; Posthole units placed within the s.i te area can be sununarized as!

Site Recommendations The shell recorded as SDMM-W-1873 was evalu,ated 'using cri'teri-a . set forth by the County of San Diego ',(Environmental Division) .. These include integrity, regional aspect, variability of the resource, ethnic value, site type represented,.' and research ,.' potential (see appendix). Results of the 1982 and 1983 studies " ' .. indicate that this resource has been badly damaged by farming and erosional activities. Subsurface testing indicate a, very limited subsurface smear of shellfish. Specific cr~teria evaluations made for this site are listed as: ' 1) integrity: site contains a light scatte,r of surface and subsurface shell, with few artifactua1 evide~ce., Past f~rming has dissected the site severely and has increased the, normal ,erosi~nal activity patt.eJ;'n. , .. 2) regional aspect: this site is located within the general Batiquitos Lagoon exploitation area, an area well' documented for prehistoric and historic use. This particular site may represent one-time useage of ~ family or household in their daily 'foraging pattern. Since no firehearths, areas of heavy lithic'or she11 scatters were noted within the matrix, no evidence " of long term occupation was noted at ,W-1873. 3) variability: site represents a single comporient-a shell smear 4) ethnic value: no diagnostic artifacts were ree:overed to ' ' determine cultural affiliation, time of useage or, , purpose of site. Questions Of who,' ~hat or 'wtieri 'can, " not really be addressed with the limited base present at W-187J 5) site type: 'site probably repr,ese,nts 'one::"time. Q,r short' useage by-small househOld; no long term ,occupation was varified. -11- , , ,; • 6) research potential: site represents a light scatter/ smear of seashell, maximum depth of 30cm, with heavy damage from past farming and current erosional activities. Questions of who, what or whe'n? are difficult to address with the recovered materials. Using the rating scale developed by the-County, this -site --would have a rating of 0.5 (see appendix). Because o~ the low potential of site integrity and n? research potential, it- is recommended that no further testing be carr~ed out within the Sea Pine Parcel. -12- V. .References Cited Berryn:tan, S. 1982 Results of an Archaeological Surv~y .. ~f Sea Pin~s, Carlsbad, California.

'.(.' . INTRODUCTION AND GENERAL PHYSIOGRAPHY The Sea Pines property is located northeast of the corner of Po i nsett i a Lane and Batlquitos Drive in Carlsbad (Figure 1). The property \'las recently c I eared and has grow n to weedy vegetat Ion. Sma I I patches of scrub hab I tat occur in a fe'l' locations, usually in association \'lith the remnant eroded 51,opes on the property. The land Is generally flat to.gentry sloping, with the E:xception of the slopes H1E:ntioned above, and higher terrain occurs immediatefy to the \'lest am! east. Elevation ranges from approximately 110 to 230 feet, a rei i e·f of 120 feet. Sha II ow dra; nage rav i nes occur across the property. D i"rt roads occur in several locations. The I and to the north and east is cu I ti"vated, \'l hi I e that to the south is covered by a resioentlal development. To the west, a narrow strip of disturbed scrub vegetation, followed by cultivated fields, separates the prop.erty from Interstate 5. The Chesterton so; Is and eroded slope areas overl ie Eocene and PI'eistocene marine terrace deposits of the site. !4'IETHODS AND SURVEY L I 1",11 TAT IONS A zoological survey of the property \'las conducted by Stephen J. Montgomery on 27 Aprl I (1615-1920) and 4 May 1982 (1700-1800). ~/eaTh'er on 27 April" consisted of scattered clouds and fog, a moderate breeze and an air temperature of 70° F. at 1630. Weather on 4·r .. lay consisted of scattered clou·ds, a 51 ight· breeze and an a I r temperature of 63 0 F. at 17 00. The ant i re prop'erty \'I"as covered on-foot using 7x35 binoculars to aid in identification of o~served species. Some unobserv~d species were detected by indireCT means. The botan i cal i nvesti gati on of the 'property was made on 4 Nay 1982 by R. ffJ'itchel Beauchamp •. The on-foot survey covered all naturally vegetated portions of the prop Grty. Nomenc I ature used in th i s report is f rom the follow i ng sources: vegetation, Thorne (1976); flora, Munz (1974) or' more recent treatments; amphibians and rapti les, Coil ins et al .(1978>; birds, A.O.U. (1957-76); and mammals, .Jones et al (1975). BOTANY , Rece~t vegetation clearing has destroyed mOST of the native vegetation on- site. Onl.y steep slope areas which were avoided by brushing equipment sti 11 retain native plant cover (Figure 2). The site was previously examined by Mr. Beauchamp In 1977 in conjunction with a Coastal Commission permit heariAg. At that time the site was covered 'tilth Coast iHxed Chaparral and Coastal S·qge Scrub. The observed flora of the site (Table 1) sti II refle~ts this" vegetat Ion, but "a I so inc I udes m any non-nat i ve ann ua lsi n the c I eared areas.

Birds A tota I of 29 bird speci es \'I as observed on the pr"operty (Tab,1 e 2). All species are common inhabitants 0)' the habitats existing on-site, except for the infrequently encountered marsh hawk. Sage sparrow"s are obs'erved" sporadically during' similar surveys of scrub vegetation, possibly because of their irregular activity patterns rather than a scarCity of individuals or spotty distribution. Those on the property occupy a small patch of coastal scrub vegetation. Of primary importance on the property are two marsh hawks o~served foraging on-site on both survey dates. One of these birds, an adult fem.ale, was observed carrying sticks in her bill just off-site near the northeastern corner of the property (Figure 2).' The zoologist's presence in this area" el icited continuous intense alarm cal Is from this bird. The bird tended to remain in this area and \'las 09served perching o"n the ground sever"aJ times on both survey days. These behaviors indicate breeding in this animal, however, "a nest area \'Ias not found; marsh hawk nests are often difficult to locate in high grass. A second bird, apparent I y another femal e, \'las a J.so observed, in the same area behaving in a similar aggressive manner toward the zoologist. ThTs courd have been an off~pring of the adult female or an intrude~ An adult male was not Observed, a)though it could have been foraging elsewhere d~ring the surveys. If th i's sens i t i ve spec i es does breed on the property, it may do so just off-site. And if not this year, its behavior suggests that it may nest in the future. The 'marsh hawk is discussed in the Sensitive Anim~Js section. A \1hite-tailed kite was o"bs"erved flying over the site and could be expected. to -forage and perch on-site on occasion. This bird does not appear to nest ~n-site but nests nearby to the southeas~ It is discussed in'the Sensitive Animals section. Mammals Observat i on and i nd i rect ev i dence detected five mamma I spec i es on the property, inc Iud i ng Botta's pocket gopher (:Ib..Q.m.Q~ bottae; burrows), Cal iforni a ground squi rrel (Spermoph i I us beechey i; observed), \'Ioodrat CNeotoma. . ·sp.; nest), desert cottontail (Sylvllagus audubooil; observed) andcoy6te (Canis latrans~ scat, possibly a burrow). All are common species in the area .. Additional common species ar~ expected, primeri Iy in shrubby habitats. '. A large mammal burrow, located near one of the steep slopes~ may belong to e i thar a coyote or gray fox (UrocYQO c i nereoargeoteus), a I thougfl nei ther species was observed there. RESOURCE/HABITATvEVALUATlON Recently cultivated fields, riparian woodland and scrub veg,et-ation are the primary wildlife habitats on-site. Minor habitats include a fei'l small tree- I ike plants and a smal I marshy are~ A large fI1pJority of the property consists of cultivated fields that have grown back to. various weedy gra.sses and for:b.s, some of these reach.ing heighTS of five to six feet. This vegetation forms cover for a fe\'/ small mammals and' reptiles; however, in general the scarcity of shrub cover restricts the divesity of non-avian species in these fields.· Raptors hunt over these fields in more open vegetation. Two marsh hawks exhibiting possible breeding behavior, \'IE~re observed in this habitat in tall grass. These birds were also seen foraging over the entire property on t\W separate days. A narrow wi 110\1/ stand, approximately 600 feet in length, occurs along the southern property boundar~ Tree heights here r~ach 20 to 25 feet. This riparian vegetation is known to be important breeding and feeding habitat for numerous bird species, particularly for warblers. Although no .\'1arblers \I/'ere observed there, an ear I y morn i ng survey \'iOU I d very like I y detect some of these bfrds. The isolation and relatively short length of this \'iOodland w,ould tend to reduce its use by riparian speclv~. Scrub vegetation, consisting ,).' l-haparral and/or sage ,scrub associations, 0.;curs in a few locations on-site. In general, this vegetation remains \'Ihere s-;--:lep S I opcs and ridges have impeded I and excavati on. , On th i s property, such dense shrubby areas are refuges for a variety of reptiles, sma~l ma~mals and scrub-associated birds which would otherwise be very scarce' or not present at',' a II. A I args burrow, poss i b Iy used by a coyote or fox, was found along the top of a slope exhibiting this habitat type. ' The small marshy area on-site h,as developed as a result of run-off \'1ater from the greenhouses to the east. This I'later will be used by numerous wildlife' speei es, i ncl ud i ng any I arge mamma lsi n the area. A treefrogheard 'call i ng· in this area illustrates its utility to the few amphibians expected on'the property. The I arge tree-I ike sh rubs that occu r ina few I'ocat i cns on-s i te receive concentrated use by perching and nesting birds. In general, the i'l i I dl ife habitats on the property are of low qual ity due to the removal of most native vegetation for cultiva+ion. The \d.llo\'l ,wood'iand is relatively high qual ity breeding and foraging habitat for bird<s. The portions ot the property that exhibit high~ dense grass growth are vall,lable ,as Table 2.

The presence of a large mammal burrow adjacent to one of the shrubby slope areas suggests tha~ even when cultivated and surrounded by severely disturbed lands, this property can be of considerable value to larger wildlife in the area.

SENS ITIVE AN·I MALS Table 3 contains a list of species which are co;nsidered sensitiVe'by a variety of sources a~ explained in Appendix 2 • . ~ SENSITI'VE HABITATS The l'Iil low woodland is the only officially sensitive habftat on the property. It is dense but narrow on-s i te and lies i mmed i ate,1 y adj acent to a. row of h'ouses. As ment i oned, the i sol ati on of th is hab i. tat from other si flii I ar habitats, as well as its short length, reduce its util lty to most riparian species. However, -rhis woodland does provide high qual ity habitat to a variety of birds in an area that is otherwise sorely lacking in na~ive woodland vegetation. Long-term value of this riparian habitat to I'lildl i·fe is questionable due i"o the uncertai nty of water f 10\'1 -ro the wood land from the adjacent greenhouse operation. If the water supply is curtai led, the woodland \'1111 likely ·decrease in density and overall structural diverSity. This wil" in turn, diminish its use by wi I d I if e. The smal I pptch of marsh and associated stream are important to. a 'number of birqs and other animal groups. Due to its small size, however, this hab.itat is of limited value to wildlife relative to larger similar habitats nearby.

Listing of the latter two is based in large part on prior an,d, on- gO'ing work of the former, non-profit organization. The CNPS has the most complete listing of sensitive plants which appears as the Society's Special Publ ication Number 1 (second'edition)lnventory.Q.f B..ru:.e.?llli1 Endangered, Vascular Plants Qf California (Smith et 'al. 1980 and, supp I ement 1981>. Th i s list i ng scheme uses the d i 9,i ts 1,' 2, and 3 to descr ibe, a IO\,i to high level of rarity, endangerment, vigor, or distr'ibution for each listed taxon. Therefore, a p I ant I lsted 3-3-3-3 is much more rare and endangered than one listed 1-1-1-1. Further, there are fou~ named lists:, "p I ants presumed ext i nct"; and lip I ants rare inCa I i forn i a, common e I se\'I here". Tha first appendix includes "plants considered but not fncluOed". ", The Fish and Game Commission (of the CDFG), as of 19 December 1979, had listed 14 San D'iego County plants as "Rare" or "Endangered". The Sacramento Endangered Spec i es Of f ice of th,eUSFW S. has pub I is,hed ,a Draft notice of Revie\'/ o,f candidate "Endangered", "Threatened",' and"Sensitivell , plants as of 2 March 1980.

APPENDIX II SENS ITI VI AN U,JALS Sensitive animals are described or protected by a variety of authorities and documents as described below. The U.S. Fish and ~1ildl ife Service (uSFWS) officially lists sensitive speci es as ei ther "Threatened" or "Endangered". Some' as yet un listed speci es are unofficially recognized as candidates for I isting. Listed species are found periodically in the Endangered SpeCies Technical Sui letin and the Federal Beg i ster. Other federal lists i ncl ude the Bal d Eagl e Act, rvlj gra,tory Bird Act, and the f~lari ne Mammal Protecti on Act. TheCaliforn'ia Fish and Game Commission of the California Department'of Fish and Game (CDFG), officially I ists some sensitiv~ species as either'IIRarell or "Endang,ered"j and these are found in the period,ically updated publlCerion .At .lb.e Crossroads. The CDFG further c f ass if i es certai n ,sped es ' under' the follow i ng categori es: "Fu II y Protected", nProtected Furbearer", "Protected Amphibian", and "Protected Reptile". The designation "Pro+ected,II indicates that a speci es may not be taken or possessed except under speci al permit from the CD.fGj "Fully Protected" means a species can be taken only for scientific purposes. Non-governmental ~ ists are also important indicators of sensitive wtldl ife species, as described below. ' The Audubon Blue L'lst is an annually updated I ist of birds consloered to' be declining in the United States. Local' populations may differ in status from the general ,Blue List status for the entire United States. ' The International Union for the Conservation of Nature and Natural Resources (IUCN) is an international conservation organization that publ'ishes lists of species considered to be declining throughout the world. The status ,of "depletedll indicates that a species is not currently threatened with extin,ction but there are indications that it may become so. The San Diego Non-Game Wildl ife Subcomm;'ttee (SDNGWS) is a group of local biologists that formulated a list of animals that appear to be experiencing reduced population numbers in the county. ' Thei.r use of the term "threatened" in'dicates that a species, is considered to be rare, endangered, declining, or depleted in San Diego County. The SDNGWS ts officially sanctioned by theCDFG •. Th,e Species of Special Concern List by J.V. Remsen, Jr. is a I i,st of bird species in Cal ifornia that are decl ining. It is publ ished by the Nuseum of Vertebrate Zoology at the University of Cal ifornia at'Berkeley_ It excludes birds, already on Federal or Cal ifornia Endangered, Threatened, or Rare lists, those species historically much more common than at present but not in ,current danger of extirpation, those species I'/ith very small ranges or pop,ulations in the state but primarily associated with man-made habitats, and those species for which cons~stent breeding has not been proven, only fluke occurrences. Three categori es are recogn i zed. Highest pr i or i ty category birO's ,face immediate extirpation if current trends continue. Second priority category spa'cies are definitely on the decline but dan'ger or extirpation isno+ imliled i ate. Species in the lowest priority category have sufficiently small , " populations that make them vulnerable to extirpation should a threat materi al ize. The Survey and Status of Endangered and Threatened Species of Reptil.es Natively Occurring in San Diego County is a report compiled by members of the San Diego Herpetological Society (SDHS). This report I ists ~he societyts determinations of the endangered or threatened status of rare and depteted repti les occurring in the county. An endangered species is defined as one whose po-pulation and habitat distribution have been reduced to such a \vi despread extent that the spec i es is unab I e to reproduce at a norma I rate and is imminently near extinction throughout the majority of ~ts remaining distributio~ A threatened species is defined as one which h~s had Significant population· depletion and/or habitat destruction and is potentiafly endangered but presently reproducing at or near normal where it sti II occurs.
