dc.description.abstractThe Hydrogeomorphic (HGM) Approach is a suite of concepts and methods used collectively to develop functional indices and apply them to the assessment of wetland functions. A National Action Plan (NAP) to implement the HGM Approach has been cooperatively developed by the U.S. Army Corps of Engineers (USACE), U.S. Environmental Protection Agency (USEPA), Natural Resources Conservation Service (NRCS), Federal Highways Administration (FHWA), and U.S. Fish and Wildlife Service (USFWS). Implementation of the Hydrogeomorphic Approach is accomplished in two phases: a Development Phase and Application Phase. The Development Phase is achieved by an interdisciplinary team of regional experts responsible for developing a regional guidebook by classifying wetlands, characterizing a regional subclass, developing assessment models for that subclass, and calibrating the models with data from reference wetlands. This guidebook provides a template for developing regional HGM guidebooks for wetlands belonging to the tidal fringe class.US_en
