    Description

    A recent publication and an article in Wetland Science & Practice (Lichvar and Gillrich 2014b, 2014a) discuss two metrics for determining if vegetation is hydrophytic for purposes of U.S. wetland delineations, the Prevalence Index (PI) and a proposed Hydrophytic Cover Index (HCI). Based on Wentworth et al. (1988), the PI is a weighted average of ordinal scores (1-5) for species in five wetland-indicator categories (defined in Table 1). 􀀐 􀁌􀁑􀁇􀁌􀁆􀁄􀁗􀁒􀁕􀀃􀁆􀁄􀁗􀁈􀁊􀁒􀁕􀁌􀁈􀁖􀀃􀀋􀁇􀁈􀂿􀁑􀁈􀁇􀀃􀁌􀁑􀀃􀀷􀁄􀁅􀁏􀁈􀀃􀀔􀀌􀀑􀀃􀀶􀁆􀁒􀁕􀁈􀁖􀀃􀁒􀁉􀀃􀀔􀂱􀀖􀀃
