Wedands wcrc identificd on thc basis of thrcc <br /> criteria: (1) hydrophytic vcgctation, (2) hydric soils, and (3) evidcnce of �vetl:u�d hydrology as <br /> described in the It�ns/ting(a� Stnte IVedrmrls/rlei�lificntion and Delinenlion Mmu�n/(�cology, 1997) <br /> and thc U.S. Arnry Co�Ps ojEngineers �Verlcr�uls Delineatio�r tiln�runl (Environmental Laboratory, <br /> 1987) and subsequent Corps guidance. llydrophytic vegetation (i.e., plants adapted to saturated soil <br /> conditions) �vas identified as prescnt when dominanl cover of plants observed had an indicator <br /> status of facultative (PAC), fxuitative wedand (PACW), or obligate wetland (OBL) (Tablc 1) <br /> (Reed, 1988). Pl:uit spccics �vere identificd following Hitchcock and Cronquist (1973), but updated � <br /> nomenclaturc was used �vherc kno���n. I lydric soils were detcmiined on the basis of organic matter <br /> contcnt, appropriate chroma, and presencc of redoxymorphic feahues or other hydric characteristics <br /> as stated in the methodology. <br /> Tablc 1: <br /> Ucfinition of Plant Indicator Status <br /> Indicator ` .�.�"� � <br /> Indicator Category.
