JULY 2012 JUiliSDICTIONAL DELINEATION COASTAL llAIL TllAIL !lEACH I CARLSBAD, CALIFORNIA INTRODUCTION This report presents the results of a jurisdictional delineation (JD) conducted by LSA Associates, Inc. (LSA) of potential wetlands and waters subject to the jurisdiction of the United States Army Corps of Engineers (USACE), California Department of Fish and Game (CDFG), Regional Water Quality Control Board (RWQCB), and California Coastal Commission (CCC) within the biological study area (BSA) for the proposed Coastal Rail Trial Reach 1 Project (project). The BSA is located in the City of Carlsbad (City), San Diego County (County), California (Figure 1). Specifically, this report addresses the requirements of the Federal Clean Water Act (CW A), the California Fish and Game Code, and the California Coastal Act. This report has been prepared for use by the USACE, CDFG, RWQCB, and CCC as part of their review of applications for permit authorization. This routine wetland and jurisdictional delineation was conducted under contract to the City. The findings and conclusions presented in this report, including the location and extent of wetlands and other waters subject to regulatory jurisdiction, represent the professional opinion of LSA and should be considered preliminary until verified by representatives of the USACE, CDFG, and CCC. PROPOSED PROJECT The City intends to install Reach 1 of the Coastal Rail Trail and construct a roundabout at the intersection of South Coast Highway and State Street to enhance safety and access. The project will connect the two cities of Carlsbad and Oceanside with a pedestrian trail, Class I bicycle paths, and sidewalks across the Buena Vista Lagoon. The existing vehicle lanes will be repurposed to provide sufficient space for expansion. The roundabout will serve as a safety enhancement as part of the Coastal Rail Trail (CRT) Reach 1. Additionally, the CRT Reach 1 will connect along State Street at Oak A venue with Reach 2. The sidewalk to be added will provide access for pedestrians to the Buena Vista Lagoon Nature Center. SITE DESCRIPTION The entire BSA is located within the South Coast subregion of the Southwestern California region of the California Floristic Province, characterized by valleys and small hills extending from the coast inland to the foothills of the Transverse and Peninsular Mountain ranges. Specifically, the project is located in Section 1, Township 12 South, and Range 5 West, of the United States Geological Survey (USGS) San Luis Rey, California 7.5-minute topographic quadrangle map. The project area extends from Eaton Street on the north, along South Coast Highway to the intersection at State Street on the south. The majority of the BSA consists of paved streets (South Coast Highway) and only a small portion of the BSA is undeveloped. The undeveloped land within the BSA consists of previously disturbed areas dominated by bare ground, ornamental/landscaped vegetation, non-native, annual vegetation, disturbed coastal brackish marsh, and riparian woodland. The City's Maxton Brown Park is located at the southeastern end of the BSA along the east side of State Street. The entire BSA is located within the Carlsbad Hydrologic Unit (HU) (Carlsbad Watershed), which is approximately 210 square miles in area extending from the headwaters above Lake Wolhford in the P:\HCR1202-CRT Reach 1\Biology\JD\JD Report CRTI_Draft.doc «7118/2012>> 1 L SA LEGEND c:J Project Location 1000 2000 FEET SOURCE: USGS 7.5' Quad-San Luis Rey (1975), CA 1:\HCR 1202\G IS\Fig I_ProjectLocation.mxd (7(2(20 12) FIGURE l Carlsbad Rail Trail Reach I Project Location ------------------- LSA ASSOCIATI!S, INC.

The Cities of Carlsbad, San Marcos, . and Encinitas are entirely within this watershed. There are numerous important surface hydrologic features within the Carlsbad Watershed, including four unique coastal lagoons, three major creeks, and two large water storage reservoirs. The HU contains four major, roughly parallel hydrologic areas (HAs). Encompassing the study area is the Buena Vista Creek (904.2) HA and the El Saito hydrologic subarea (HSA) according to the Water Quality Control Plan for the San Diego Basin-Region 9 (State of California 2007). The average annual rainfall for the BSA is approximately 11.13 inches/ typically ranging from 10 to 16 inches.2 REGULATORY BACKGROUND United States Army Corps of Engineers The USACE regulates discharges of dredged or fill material into waters of the United States. These waters include wetland and non wetland bodies of water that meet specific criteria. USACE regulatory jurisdiction pursuant to Section 404 of the CW A is founded on a connection, or nexus, between the water body in question and interstate commerce. This connection may be direct (through a tributary system linking a stream channel with traditional navigable waters used in interstate or foreign commerce) or may be indirect (through a nexus identified in the USACE regulations). The following definition of waters of the United States is taken from the discussion provided at 33 Code of Federal Regulations (CFR) 328.3: "The term waters of the United States means: (1) All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce ... ; (2) All interstate waters including interstate wetlands; (3) All other waters such as intrastate lakes, rivers, streams (including intermittent streams) ... the use, degradation or destruction of which could affect interstate or foreign commerce ... ; (4) All impoundments of waters otherwise defined as waters of the United States under the definition; and (5) Tributaries of waters defined in paragraphs (a) (1)-(4) of this section." The US ACE typically regulates as waters of the United States a body of water displaying an ordinary high water mark (OHWM). USACE jurisdiction over nontidal waters of the United States extends laterally to the OHWM or beyond the OHWM to the limit of any adjacent wetlands, if present (33 CFR 328.4). The OHWM is defined as "that line on the shore established by the fluctuations of water and indicated by physical characteristics such as a 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 area." (33 CFR 328.3) Jurisdiction typically extends upstream to the point where the OHWM is no longer perceptible. http://www .idcide.corn!weather/ca/carlsbad.htm, July 9, 2012. http://ortho.ftw.nrcs.usda.gov/osd/dat/C/CARLSBAD.html, December 16,2009.

JULY 2012 JURISDICTIONAL Dl!LINKATION COASTAL RAIL TRAIL Rl!ACH I CAltLSKAD, CALII'OltNlA As discussed above, USACE regulatory jurisdiction under Section 404 of the CW A is founded on a connection between the water body in question and interstate commerce. In the past, an indirect nexus could potentially be established if isolated waters provided habitat for migratory birds, even in the absence of a surface connection to a navigable water of the United States. The 1984 rule that enabled the US ACE to expand jurisdiction over isolated waters of this type became known as the Migratory Bird Rule. However, on January 9, 2001, the United States Supreme Court narrowly limited USACE jurisdiction of "nonnavigable, isolated, intrastate" waters based solely on the use of such waters by migratory birds and particularly, the use of indirect indicators of interstate commerce (e.g., use by migratory birds that cross state lines) as a basis for jurisdiction. The Court's ruling derives from the case Solid Waste Agency of Northern Cook County v. U.S. Anny Corps of Engineers, No. 99-1178 (SW ANCC). The Supreme Court determined that the USACE exceeded its statutory authority by asserting CWAjurisdiction over an abandoned sand and gravel pit in northern Illinois, which provides habitat for migratory birds. In 2006, the United States Supreme Court further considered US ACE jurisdiction of "waters of the United States" in the consolidated cases Rapanos v. United States and Carabell v. United States (126 S. Ct. 2208), collectively referred to as Rapanos. The Supreme Court concluded that wetlands are "waters of the United States" if they significantly affect the chemical, physical, and biological integrity of other covered waters more readily understood as navigable. On June 5, 2007, the USACE issued guidance regarding the Rapanos decision. This guidance states that the USACE will continue to assert jurisdiction over traditional navigable waters, wetlands adjacent to traditional navigable waters, relatively permanent non-navigable tributaries that have a continuous flow at least seasonally (typically three months), and wetlands that abut rela~vety permanent tributaries. The USACE will determine jurisdiction over waters that are non-navigable tributaries that are not relatively permanent and wetlands adjacent to non-navigable tributaries that are not relatively permanent only after making a significant nexus finding. Furthermore, the preamble to USACE regulations (Preamble Section 328.3, Definitions) states that the USACE does not generally consider the following waters to be waters of the U.S. The USACE does, however, reserve the right to regulate these waters on a case-by-case basis. • Nontidal drainage and irrigation ditches excavated on dry land; • Artificially irrigated areas that would revert to upland if the irrigation ceased; • Artificial lakes or ponds created by excavating and/or diking dry land to collect and retain water and which are used exclusively for such purposes as stock watering, irrigation, settling basins, or rice growing; • Artificial reflecting or swimming pools or other small ornamental bodies of water created by excavating and/or diking dry land to retain water for primarily aesthetic reasons; and • Water-filled depressions created in dry land incidental to construction activity and pits excavated in dry land for purposes of obtaining fill, sand, or gravel unless and until the construction or excavation operation is abandoned and the resulting body of water meets the definition of waters of the U.S. P:\HCR1202-CRT Reach 1\Biology\JD\JD Report CRTI_Diaft.doc «7118/2012» 4 LSA ASSOCIATES, INC. JULY2012 JURISDICTIONAL DELINEATION COASTAL JI.AIL TJI.AIL REACH I CARLSBAD, CALIFORNIA Waters found to be isolated and not subject to CW A regulation are often still regulated by the Regional Water Quality Control Board (RWQCB) under the State Porter-Cologne Water Quality Control Act (Porter-Cologne Act). Wetlands Wetland delineations for Section 404 purposes must be conducted according to the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (Regional Supplement) (USACE 2008) and the Corps of Engineers 1987 Wetland Delineation Manual (1987 Manual) (Environmental Laboratory 1987). Where there are differences between the two documents, the Regional Supplement takes precedence over the 1987 Manual. The US ACE and United States Environmental Protection Agency (EPA) define wetlands as follows: "Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated soil conditions." In order to be considered a jurisdictional wetland under Section 404, an area must possess three wetland characteristics: hydrophytic vegetation, hydric soils, and wetland hydrology. Each characteristic has a specific set of mandatory wetland criteria that must be satisfied in order for that particular wetland characteristic to be met. Several indicators may be analyzed to determine whether the criteria are satisfied. Hydrophytic vegetation and hydric soils indicators provide evidence that episodes of inundation have lasted more than a few days or have occurred repeatedly over a period of years, but do not confirm that an episode has occurred recently. Conversely, wetland hydrology indicators provide evidence that an episode of inundation or soil saturation occurred recently, but do not provide evidence that episodes have lasted more than a few days or have occurred repeatedly over a period of years. Because of this, if an area lacks one of the three characteristics under normal circumstances, the area is considered non wetland under most circumstances. Determination of wetland limits may be obfuscated by a variety of natural environmental factors or human activities, collectively called difficult wetland situations, including cyclic periods of drought and flooding or highly ephemeral stream systems. During periods of drought, for example, bank return flows are reduced and water tables are lowered. This results in a corresponding lowering of ordinary high water and invasion of upland plant species into wetland areas. Conversely, extreme flooding may create physical evidence of high water well above what might be considered ordinary and may allow the temporary invasion of hydrophytic species into nonwetland areas. In highly ephemeral systems typical of southern California, these problems are encountered frequently. In these situations, professional judgment based on years of practical experience and extensive knowledge of local ecological conditions comes into play in delineating wetlands. The Regional Supplement provides additional gutdance for difficult wetland situations. Hydrophytic Vegetation. Hydrophytic vegetation is plant life that grows and is typically adapted for life in permanently or periodically saturated soils. The hydrophytic vegetation criterion is met if more P:\HCR1202-CRT Reach 1\Biology\JD\JD Report CRTl_Draft.doc «7/1812012» 5 LSA ASSOOIATI!S, INC. JULY 2012 JURISDICTIONAL DI!LINI!ATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA than 50 percent of the dominant plant species from all strata (tree, shrub, herb, and woody vine layers) are considered hydrophytic. Hydrophytic species are those included on the Arid West Final Draft Ratings: U.S. Army Corps of Engineers, Cold Regions Research and Engineering Laboratory (CRREL 2011), published by the USACE. Each species on the list is rated according to a wetland indicator category, as shown in Table A. To be considered hydrophytic, the species must have wetland indicator status (i.e., be rated as OBL, FACW, or FAC). Table A: Hydrophytic Vegetation Category Probability Obligate Wetland OBL Almost always occur in wetlands (estimated probability> 99%) Facultative FACW Usually occur in wetlands (estimated probability 67-99%) Wetland Facultative FAC Equally likely to occur in wetlands and nonwetlands (estimated probability 34- 66%) Facultative Upland FACU Usually occur in nonwetlands (estimated probability 67-99%) Obligate Upland UPL Almost always occur in nonwetlands (estimated probability> 99%) The delineation of hydrophytic vegetation is typically based on the most dominant species from each vegetative stratum (strata are considered separately); when more than 50 percent of these dominant species are hydrophytic (i.e., FAC, FACW, or OBL), the vegetation is considered hydrophytic. In particular, the USACE recommends the use of the "50/20" rule (also known as the dominance test) from the Regional Supplement for determining dominant species. Under this method, dominant species are the most abundant species that immediately exceed 50 percent of the total dominance measure for the stratum, plus any additional species comprising 20 percent or more of the total dominance measure for the stratum. In cases where indicators of hydric soil and wetland hydrology are present but the vegetation initially fails the dominance test, the prevalence index must be used. The prevalence index is a weighted average of all plant species within a sampling plot. The prevalence index is particularly useful when communities only have one or two dominants, where species are present at roughly equal coverage, or when strata differ greatly in total plant cover. In addition, USACE guidance provides that morphological adaptations may be considered when determining hydrophytic vegetation when indicators of hydric soil and wetland hydrology are present (US ACE 2006). If the plant community passes either the dominance test or prevalence index after reconsidering the indicator status of any plant species that exhibit morphological adaptations for life in wetlands, then the vegetation is considered hydrophytic. Hydric Soils.' Hydric soils are defined as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part. 2 Soils are considered likely to meet the definition of a hydric soil hydric when one or more of the following criteria are met: The hydric soil definition and criteria included in the 1987 Manual are obsolete. Users of the Manual are directed to the United States Department of Agriculture (USDA) Natural Resources Conservation Service Web site for the most current information on hydric soils. Current definition as of 1994 (FR July 13, 1994). P:\HCR1202-CRT Reach 1\Biology\JD\JD Report CRTI_Diaft.doc «7118/2012» 6 LSA ASSOCIATES, INC. JULY 2012 JURISDICTIONAL DELINEATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA 1. All Histels except Folistels and Histosols except Folists; or 2. Soils that are frequently ponded for long duration or very long duration1 during the growing season; or 3. Soils that are frequently flooded for long duration or very long duration during the growing season. Hydric soils develop under conditions of saturation and inundation combined with microbial activity in the soil that causes a depletion of oxygen. While saturation may occur at any time of year, microbial activity is limited to the growing season, when soil temperature is above biologic zero (the soil temperature at a depth of 50 centimeters (em), below which the growth and function of locally adapted plants are negligible). Biogeochemical processes that occur under anaerobic conditions during the growing season result in the distinctive morphologic characteristics of hydric soils. Based on these criteria, a National List of Hydric Soils was created from the National Soil Information System (NASIS) database and is updated annually. The Regional Supplement has a number of field indicators that may be used to identify hydric soils. Natural Resources Conservation Service (NRCS) (2003) has also developed a number of field indicators that may demonstrate the presence of hydric soils. These indicators include hydrogen sulfide generation, accumulation of organic matter, and the reduction, translocation and/or accumulation of iron and other reducible elements. These processes result in soil characteristics that persist during both wet and dry periods. Separate indicators have been developed for sandy soils and for loamy and clayey soils. Wetland Hydrology. Under natural conditions, development of hydrophytic vegetation and hydric soils are dependent on a third characteristic: wetland hydrology. Areas with wetland hydrology are those where the presence of water has an overriding influence on vegetation and soil characteristics due to anaerobic and reducing conditions, respectively (Environmental Laboratory 1987). The wetland hydrology parameter is satisfied if the area is seasonally inundated or saturated to the surface for a minimum of 14 consecutive days during the growing season in most years (USACE 2008). Hydrology is often the most difficult criterion to measure in the field due to seasonal and annual variations in water availability. Some of the indicators that are commonly used to identify wetland hydrology include visual observation of inundation or saturation, watermarks, recent sediment deposits, surface scour, and oxidized root channels (rhizospheres) resulting from prolonged anaerobic conditions. California Department of Fish and Game The CDFG, through provisions of the California Fish and Game Code (Sec. 1600 et seq.), is empowered to issue agreements for any alteration of a river, stream, or lake where fish or wildlife resources may be adversely affected. Streams (and rivers) are defined by the presence of a channel bed and banks and at least an intermittent flow of water. The CDFG regulates wetland areas only to Long duration is defined as a single event ranging from 7 to 30 days; very long duration is defined as a single event that lasts longer than 30 days. P:\HCR1202-CRT Reach 1\Bio1ogy\JD\JD Report CRTI_Diaft.doc «711812012>> 7 LSA ASSOCIATES, INC. JULY 2012 JURISDICTIONAL DELINEATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA the extent that those wetlands are part of a river, stream, or lake as defined by the CDFG. Also, the CDFG typically does not regulate estuaries below the mouth of the tributary river or stream. Furthermore, because this project falls within the Surface Transportation Board (STB) ruling that Federal law preempts any requirement for state or local approval/permits, it would not typically be subject to CDFG regulation. However, because it may hold an interest in the conservation easement over the vernal pools at the station, the CDFG will be consulted for authorization to work within the easement. In obtaining CDFG agreements, the limits of wetlands are not typically determined. The reason for this is that the CDFG generally includes, within the jurisdictional limits of streams and lakes, any riparian habitat present. Riparian habitat includes willows, mule fat, and other vegetation typically associated with the banks of a stream or lake shorelines and may not be consistent with USACE definitions. In most situations, wetlands associated with a stream or lake would fall within the limits of riparian habitat. Thus, defining the limits of CDFG jurisdiction based on riparian habitat will automatically include any wetland areas and may include additional areas that do not meet US ACE criteria for soils and/or hydrology (e.g., where riparian woodland canopy extends beyond the banks of a stream away from frequently saturated soils). Regional Water Quality Control Board The RWQCB is responsible for the administration of Section 401 of the CW A and the California Water Code Porter-Cologne Water Quality Control Act (Water Code Section 13260). Section 401 of the CW A specifies that certification from the State is required for any applicant requesting a Federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities that may result in any discharge into navigable waters. The Porter-Cologne Act requires "any person discharging waste, or proposing to discharge waste, within any region that could affect the waters of the State" to file a report of discharge. Typically, the areas subject to RWQCB jurisdiction coincide with those of the USACE (i.e., waters of the U.S., including any wetlands). California Coastal Commission The CCC, through provisions of the California Coastal Act, is empowered to issue a Coastal Development Permit (CDP) for many projects located within the Coastal Zone. In areas where a local entity has a certified Local Coastal Program (LCP), the local entity (e.g., City of Carlsbad) can issue a CDP only if it is consistent with the LCP. The CCC, however, has appeal authority for portions of LCPs and retains jurisdiction over certain public trust lands and in areas without an LCP. Because this project falls within the STB ruling that Federal law preempts any requirement for state or local approval/permits, it would not typically be subject to CCC regulation except as required for a Federal Consistency Certification. However, because it may hold an interest in the conservation easement over the vernal pools at the station, the CCC will be consulted for authorization to work within the easement. The CCC's definition of wetlands, as defined in Section 30121 of the Coastal Act and Title 14 § 13577 of the CCC' s regulations, is distinctly different from the US ACE definition of wetlands. According to the CCC's regulations, wetlands are defined as "land where the water table is at, near, or above the land surface long enough to promote the formation of hydric soils or to support the P:\HCR1202-CRT Reach 1\Bio1ogy\JD\JD Report CRTI_Draft.doc <<7118/2012» 8 LSA ASSOCIATI!S, INC. JULY 2012 JURISDICTIONAL DI!LINI!ATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA growth of hydrophytes." Both definitions focus on three fundamental wetland characteristics: hydrology, soils, and vegetation. However, while the USACE definition requires the existence of all three wetland characteristics for an area to be considered a wetland, the CCC's definition of wetlands is based on the existence of only two characteristics: wetland hydrology sufficient to either support a prevalence of hydrophytic vegetation or promote the formation of hydric soils. (Exceptions include certain areas that lack wetland soils and vegetation.) It is noted that, under certain circumstances, reliable indicators of all required characteristics are not necessarily apparent, and areas may be delineated as wetlands by the US ACE on the basis of indicators of only two of the three characteristics. The CCC routinely makes jurisdictional wetlands determinations based on the presence of one characteristic indicator (i.e., wetland soils or vegetation) under the assumption that wetland hydrology must be present in order for the indicator to be present Nevertheless, the presence of wetland hydrology during some portion of most years is fundamental to the existence of any wetland, and the CCC will sometimes disregard vegetation or soil indicators when there is sufficient evidence to conclusively refute the presence of wetland hydrology. METHODOLOGY The fieldwork for this evaluation was conducted by LSA biologists Dan Rosie and Jaime Morales on July 3, 2012. Field maps of the area to be surveyed were prepared using a 2010 aerial photograph base at a scale of I inch = 40 feet. The project area was surveyed on foot, and all areas of potential jurisdiction were evaluated according to USACE, CDFG, and CCC criteria. Data were recorded directly on the field maps. Areas supporting hydrology or species of plant life potentially indicative of wetlands were evaluated according to routine wetland delineation procedures described in the Regional Supplement. Representative sample points were selected and examined in the field in those areas where wetland jurisdiction was in question or needed to be confirmed. At each sample point, the dominant and subdominant plant species were identified and their wetland indicator status (CRREL 2011) noted. A small sample pit (approximately 20 inches deep) was dug at each point in order to examine soil characteristics and composition. Soil matrix colors were classified according to the Munsell Soil Color Charts (Munsell Color 2000). Hydrological conditions, including any surface inundation, saturated soils, groundwater levels, and/or other wetland hydrology indicators, were recorded. General site characteristics were also noted. Standard data forms were completed for each sample point; copies of these data forms are included in Appendix A of this report. RESULTS Three features were identified within the BSA during the survey. However, Feature 1 consists of 10 separate sub-features scattered throughout the northern half of the BSA on either side of South Coast Highway. For purposes of this analysis, the features have been assigned arbitrary alphanumeric names. Figure 2 depicts the locations of these features and soil sample points. Figure 3 shows site conditions related to potentially jurisdictional areas and a view of each soil sample pit.

JULY 2012 JURISDICTIONAL DELINEATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA ANALYSIS OF FUNCTIONS AND VALUES OF POTENTIAL WATERS OF THE UNITED STATES The following is an assessment of the functions and values attributable to the identified potential jurisdictional waters in the study area. All waters have some degree of functionality, and no single drainage can perform all of the functions considered below. The followin~f~nctions are analyzed at low, moderate, or high value levels. The individual drainages are analy~0'ill'Table A-1 (following) based on the criteria outlined below. · <~ HYDROLOGIC REGIME ,..>..;,, ., ' This function is the ability of a wetland or stream to abS(Iro and store water below of this saturation is dependent on the soil compositio · . is affec~d by prior floo example, clay soils possess more pore space than san ..

SEDIMENT .. NTIO~ ,,:'f",)h., ' "', Removal of sediment l,~ process that keeps sediments from migrating downstream. This is accomplished through t}le natural process of sediment retention and entrapment. This function is dependent on the sediment load being delivered by runoff into the watershed. Similar to above, the vegetation, shape, and configuration of a wetland will also affect sediment retention if water is detained for long durations, as would be the case with dense vegetation, a bowl-shaped watershed, or slow-moving water. This function would be demonstrated (i.e., high) if the turbidity of the incoming water is greater than that of the outgoing water.

JULY 2012 JURISDICTIONAL DELINEATION COASTAL RAIL TRAIL REACH I CARLSBAD, CALIFORNIA NUTRIENT RETENTION AND TRANSFORMATION Nutrient cycling consists of two variables: uptake of nutrients by plants and detritus turnover, in which nutrients are released for uptake by plants downstream. Wetland systems in general are much more productive with regard to nutrients than upland habitats. The regular availability of water associated with the wetland or stream may cause the growth of plants (nutrient uptake) and associated detritivores and generate nutrients that may be utilized by a variety of aquatic and terrestrial wildlife downstream. TOXICANT TRAPPING The major processes by which wetlands remove nutrients and tox\~ants sediments rich in nutrients and toxicants, (2) by absorption into soils high i content or organic matter, and (3) through nitrification and denitrification ina!teflt~ling oxic and · ·c conditions. Removal of nutrients and toxicants is closely tied to the processes. that provide fo jment" removal. \~)\t*'~ "''~' SOCIAL SIGNIFICANCE This is a measure of the probability that a w tilized by the public for its natural features, economic value, official st . . .eludes public use for recreational uses, such as boating, fishing, bC' · g, and othe • · "ve recreational activities.
