the vicinity (or some other meaningful subset of the landscape surrounding the site). • A qualitative discussion of terrestrial habitat in the region. Wetlands Wetlands are specialized habitats with properties intermediate between terrestrial and aquatic. The Federal definition of wetlands is presented in 33 CFR 328, “Definitions of Waters of the United States” (Ref. 32), but not all areas meeting this definition are subject to Federal regulatory jurisdiction. Unregulated areas meeting the Federal definition are termed non-jurisdictional wetlands. Some states and localities regulate wetlands independently using definitions that may vary from the Federal definition. Wetland information presented in the terrestrial ecology portions of the ER should not conflict with wetland information presented in the aquatic ecology portions. Regulatory Guide 4.11 provides additional guidance on wetlands. In general, the ER should include the following information with respect to characterizing wetlands: • An indication of whether a wetland delineation has been completed for the site and offsite parcels, what areas were addressed, and what wetland procedure was used. • A wetland delineation map and identification of each wetland using a classification system such as that used in the U.S. Fish and Wildlife Service (FWS) National Wetlands Inventory (Ref. 33), for those areas addressed by wetland delineation. • A description and estimate of the area of each wetland falling under each National Wetlands Inventory classification • Wetland mapping data from a published source (e.g., the National Wetlands Inventory maps or state wetland maps) or identification of the terrestrial habitats on the site, if any, that may contain wetlands for those project areas where no wetland delineation was performed. • A discussion of the functions and values of each wetland or cluster of interrelated wetlands (sometimes referred to as an “assessment area”) on the site or offsite
