Hydrogeomorphic Approach to Assessing Wetland Functions: Guidelines for Developing Regional Guidebooks. Chapter 3. Developing a Reference Wetland System
Abstract
In the Hydrogeomorphic (HGM) Approach, reference wetlands are the group of wetlands selected from a specific geographic area to represent the entire range of variability exhibited by a regional wetland class. Reference standard wetlands are the subset of reference wetlands used to establish the standard or comparison for calibrating assessment model variables and functional indices under the HGM Approach. This chapter provides guidelines for selecting a set of reference wetlands to represent a regional wetland subclass. It begins with the definition of terms, and continues with discussions on the purpose of reference wetlands, selection strategies, number of reference wetland sites, designation of reference wetland standard sites, and use of historical information in reconstructing reference standard wetlands.
