摘要

This report outlines an approach for assessing wetland functions in the 404Regulatory Program as well as other regulatory, planning, and management situations. Reference wetlands are selected to represent the range of variability exhibited by the regional subclass in a reference domain, and assessment models are constructed and calibrated by an interdisciplinary team based on reference standards and data from these reference wetlands. The functional indices resulting from the assessment models provide a measure of the capacity of a wetland to perform functions relative to other wetlands in the regional subclass. The application phase of the approach, or assessment procedure, includes the characterization of the wetland, assessing its functions, analyzing the results of the assessment, and applying them to a specific project. The assessment procedure can he used to compare project alternatives, determine the impacts of a proposed project, avoid and minimize impacts, determine mitigation requirements or success, as well as other applications requiring the assessment of wetland functions.
