munities The ER should briefly describe the aquatic communities based on available information (e.g., present and past studies, Federal and State sources). This description should focus on a subset of representative and important species, such as those with the following characteristics—potential or reported susceptibility to impingement and entrainment; dominance, commonness, or rarity in numbers or biomass; importance to the structure and function of the ecosystem, such as keystone species, important DG-4015, Page 18 trophic links, potential for trophic cascade, or habitat formers or modifiers; indicators of water quality or “ecosystem health”; important recreational or commercial fishing and shell fishing; fish consumption advisories; and ecosystem services. Terrestrial Communities The ER should describe the terrestrial communities briefly using available information (e.g., present and past studies, Federal and State sources) and include representative species of plants, mammals, birds, reptiles, amphibians, and insects. This description should note any endemic species, sensitive or indicator species, or keystone species. The ER should also describe bird species that nest within the area, migratory species, known migratory bird rookeries, and, if applicable, the location of the site in relation to any nearby flyways. Additionally, the ER should describe the types of vegetative communities found on and in the vicinity of the site, especially any delineated wetlands or potential wetland habitat. This section should summarize any available botanical surveys conducted on or in the vicinity of the site. Invasive Species The ER should provide occurrences of invasive species in the vicinity of the plant and document any management activities undertaken by the plant to control such species. Procedures and Protocols The ER should describe wildlife management plans and best management practices (if applicable), including pesticides and herbicides used and
