� i <br /> 1 <br /> j <br /> Hydrophytic Vegetation (Wetland Vegetation) <br />_ Wetland vegetation is detined in the 1987 Manual as "The sum total of macrophytic plant life <br /> , gro�ving in �vater or on a substrate that is at least periodically deticient in oYygen as a result of <br /> e,ccessive water content. �Vhen hydroplzytic vegetation comprises a community�vhere indicators <br /> of f�ydric soils and wetland hydrology also occtir, the area has wetland vegetation." In more <br /> stanclacd terms, some plants are more adapted to gro�ving �vithin inundatecl or saturated soil. <br /> Based on (iterature records and professionaf experience, a panel of e�cperts compiled a list of <br /> plant species ancf assi�ned each a hydropltytic status {described belo�v and includes t7ve major <br /> classes of probability of a plant occurring within a wetland). <br /> � <br /> j [n ternis of delineation there is a gradient of pla►it species that are adapted to '`growing in �vater <br />� or on substrate that is at least periodically deticient of oYygen". Fieldwock associated �vith <br />� �vetland delineations includes a procedtire (the 50/20 Rule, for determinakion of dominance), <br /> j whicf� is also outlined in the 1937 �tanual, by which to deteimine if hydrophytic plant species <br />� dominate the vegetation at a given location. This procedure has been used for the wetlanct <br />� delineation at ti�e su6ject parcel of this report. <br />� <br />; Hydric Soil <br />; Detined in the 1937 Manual as "A soil that is sat�irated, tlooded, or ponded lon; enough during <br />; tlle gro�ving season to develop anaerobic conditions tl�at favor the growth and regeneration of <br /> hydrophytic vegetation. Hydric soils that occue• in areas having positive indicators of <br /> hydrophytic vegetation and wetiand hydrology are �vetland soils." <br />� <br />� <br />� For the pu�poses of delineation of wetlands, soils cannot be viewed �vithout digging pits or <br />: e.ctracting soil using an auger. Therefore, transects of soil samples are taken fi�om perceived <br />� upland to perceived wetlands along a transitional boundary. There are specitic color indicators, <br /> i teYttu•es, and depth requirements in the soil that are revie�ved in order to determine wltether <br /> hydcic soils occ�ir at a given point or not. After a transect oF soil samples has been taken, upon <br /> consideration oP ve�etation and indicators oF appropriate hydrology a �vorking prototype for the <br /> given �vet(and is developed by the delineator. The wetland delineator then uses this �vorking <br />; pc•ototype to complete t1�e location of the remaindei•of the �vetland boundary, unless the wetland <br />� is large enough or the landscape features (vegetation or topography) change enough to �va�7•ant <br />� additional transect samples. <br /> i <br />� <br /> i i <br /> i <br />{ i <br /> i <br /> I <br />� <br /> A-3 <br /> I <br /> i <br /> I <br />
