Content:
d 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 parcels. • Citation and summary of any jurisdictional determination issued by an agency. For project areas lacking a jurisdictional determination, a description of the anticipated process for acquiring one. • Identification, when possible, of whether each wetland is under the jurisdiction of the Clean Water Act or applicable State or local wetland protection laws. DG-4026, Page 34 • An estimate of the approximate extent of wetlands in the vicinity using National Wetland Inventory maps or another source and a separate estimate for each National Wetland Inventory class or for each mapping unit used. • An estimation of the wetland losses in the context of their relative abundance in the surrounding landscape. • A qualitative discussion of wetlands in the region including the typical landscape positions commonly occupied by wetlands in the region (e.g., stream valleys, estuarine or lacustrine fringes, and topographic depressions), and the history of wetland disturbance in the region. Wildlife Guidance on identifying terrestrial wildlife is provided in RG 4.11. The ER should include the following: • Tables of wildlife species observed in each habitat (upland or wetland) on the site (and each offsite parcel or corridor) based on a minimum of one year of observations, if available. See RG 4.11 for additional direction. • A discussion of the potential value of each habitat to each major wildlife grouping: mammals, birds, reptiles, amphibians, and insects. The discussion can be qualitative and should have an ecological focus; discussions individualized to species are not usually necessary. • A discussion of wildlife activities that have the potential to substantially alter the composition or distribution of terrestrial habitat (e.g., overbrowsing or burrowing).
