When hydrophytic �egetation comprises a community where indicators <br /> o�hydric soils and wetland hydrology aiso occur, the area�has wetland vegetation." In more <br /> standard terms, some;plants are more adapted to :growing within �inundated or saturated soil. . <br /> Based on literature records and professional experience, a:panel of experts campiled a list of <br /> plant species and.assigned each a hydrophytic status (described below and includes five major <br /> classes of probabilitS�of a plant oecurring within a wetland). <br /> In terms af delineation there is a gradient of.plant species that aze adapted to "growing in water <br /> or �on substrate fhat is at least .periodicall.y deficient of°oxygen". Fieldwor:k associated witb <br /> wetland delineations include.s .a procedure (the `50120 Rule, for determination of dominance), <br /> which is also ouflined in the 1987 Manual; by which to deternune if hydrophytic plant species <br /> dominate 'the vegetation at a given location. This procedure :has been used for the wefland <br /> �delineation at the.,subject par.cel of[his report. <br /> Hydcic Soil . <br /> Def ned in the ]987.Ivianual as "A soil that is satur.ated, flooded, or ponded long enough during <br /> the growing season to d�velop anaerobic conditions that favor the growth and regenerat�on of <br /> hydrophytic vegetation. Hydric soils thar occur in areas having positive indicators of <br /> hydrophytic v.egetatioci and wetland hydrology are wetland.soils." <br /> For the purposes of delineation of wetlands, soils cannot be viewed without digging �its or <br /> extracting soil; using an auger. Therefore,, transeets of soil �samples are taken from ;perceived <br /> upland to perceiued wetlands along.a transitional boundary: There are spec�c color indicators, � <br /> texluLes; .and depth. requirements in the soil that .are reviewed in order to determine whether <br /> hydric soils occur at a given point or not'. After a transect of sail samples lias been taken, upon <br /> considerarian of vegetation and indicators of appropriate hydrolo�y a working prototype'for the <br /> given wetland is developed b� the delineator.: The wetland delineator then uses this working <br /> prototype to complete the location of the remainder of the we�larid boundai�y,.unless the wetland <br /> is large enough or the landscape features (vegetation or topography) change enough to 4varrant . . <br /> additional transect samples. <br /> � <br /> i <br /> I <br />
