Abstract

This report analyzes 17 highway wetland mitigation projects in 14 States, comparing them to natural control wetlands to evaluate the effectiveness of the mitigation to perform wetland functions and values. Field biologists used two functional assessment methods in the field to compare mitigation sites and controls. Conclusions and recommendations for mitigation are included. Volume II: Field Data Sheets, contains WET 2.0 and Hollands-Magee data sheets, as well as plant species lists from sites studied.

Abstract

A product of the Hydrogeomorphic (HGM) Wetlands Functional Assessment Program, this document provides the basic outline and guidance for regionalization of functional assessment models applicable to riverine wetlands under the HGM methodology. It explains the basis and principles behind the HGM method, describes the riverine wetland classes, and gives general functional models for different wetland functions performed by riverine wetlands that should be evaluated under the Section 404 Permit Program. Other products are being developed by the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency with continued FHWA support.
