BULL SEEP -CAMAS WETLAND DELINEATION REPORT <br />r <br />J <br />r <br />r <br />I~ <br />Classification az a wetland requires that an area have a plant species wmposition of: (1) 50 percent or grcarer by thox plants clazsifled as <br />obligare, facultative wetland, and/or facultative species, or (2) a frequency analysis of all species within a wmmuniry yielding a prevalenec index <br />value less than 3.0. Vegetation was visually characterized in each wetland area identified from atrial photography. Plant taxonomy is according <br />W Weber (1987). <br />2. Hvdroloey: The area must be inundated or samrated by surface water or groundwater pcnnanently or inlertnittendy during the growing season <br />for at least 7 days. Hydrologic conditions are azxazed through examination of surface vegetation, surface water, and soil conditions in random <br />locations. Evidence of wetland hydrology was visually determined in the field. Factors examined included apparent ponding, [cmpomry flood <br />storage, erosion, sedimentation and ground water discharge. <br />3. Soils: Soils within the root zone must be saturated pennancnny or intermittently during the growing seazon. Hydric soils arc identified by <br />various mottled and warerfogged (gleyed} conditlons apparent from surface examination ofvegetation and hydrologic conditions ar from digging <br />test holes in random locations. Mottles arc spots of contrasting wlors indicating a fluctuating warer table. Glrying is defined az grey soil colors <br />produrzd by the reduction of soil elemrnts, such az iron and manganese. <br />Soil characteristics were verified during the vegetation sampling. Soil grab samples were taken [o a depth of up to 16 inches in cash site and <br />examined in the field for hydric characteristics, such az mottles and glcying. Sail texture, wlor (Kollmorgen Carp, 1975), relative moismrc <br />content and other significant features were also noted. <br />B Clasiificarion <br />Wetlands inventoried in the project area have been classified acwrding to the US Fish and Wildlife Servioe hierarchical clazsification system <br />developed by Cowardin (Cowardin e[ al., 1979). A modified clazsifiwtion is also used to simplify the description of existing wetlands. <br />C Functional Analysis <br /> <br /> <br />11 <br /> <br />~. <br />Wetlands identified were classified according to a functional analysis developed by [he US Depamnent ofTransponation (USDGT, 1983). This <br />places wetlands N categories of funttions that thry perform <br />Groundwater recharge - Groundwater discharge <br />Shoreline anchoring - Dissipafion oferosive forces <br />Flood smrage and desynchronizetion - Sediment Trapping <br />Nutrient retention and removal - Food chain suppon/Nuvien[ export <br />Fisheries habiat - Wildlife habitat <br />Active and passive recreation antl heritage value <br />Sections 16, 17, and 9 of Township 2 South, Range 67 West. 8 <br />39° 53' 15" Latitude and 104° 53'50" Longitude, UTM ('08J70i`E.
