 Better Wetland Restoration: How Can HGM Help? Track: Environmental Management Author(s): Mary Spivey, Bill Ainslie Wetland profiling is the classification and cataloging of wetland types for a given watershed. Classification of wetland types follows the Hydrogeomorphic (HGM) Approach which emphasizes landscape position and hydrology as driving factors of wetland function. Information regarding wetland types, distribution and geospatial location aid decision makers in assessing the impacts and subsequent compensatory mitigation of wetland fill permits under Section 404 of the Clean Water Act. GIS lends itself to the efficient compilation of this wetland information over large areas. Landform descriptors are used to define the hydrographic and morphological characteristics of various hydrogeomorphic wetland types which can then be compiled by watershed. In this collaborative project, between EPA Region 4 and the U.S. Fish and Wildlife, wetland profiles are created for several watersheds in the southeastern United States. Creation of the wetland profiles involved taking the U.S. Fish and Wildlife Service=s Wetland and Deepwater Habitat classification, also known as the Cowardin Classification, and modifying it to fit the Hydrogeomorphic Classification.
