lopment Board, which works with the various river authorities in Texas. Also, some regions have organizations that may involve more than one state; examples include the Delaware River Basin Commission and the Susquehanna River Basin Commission. The NRC also recommends informally speaking with interested local agencies, such as county or municipal planning organizations and town conservation commissions. • Invasive species. Invasive species are alien species whose introduction does, or is likely to, cause economic or environmental harm or harm to human health. Invasive aquatic species include, but are not limited to, plant species, such as water hyacinth, and animal species, such as lionfish and zebra mussel. Analysts should use, among other resources, the National Invasive Species Information Center (at www.invasivespeciesinfo.gov) for this analysis. The baseline studies described in the text sections above should form a generally adequate basis for identifying important species and habitats. However, it may be necessary for analysts to conduct specialized field surveys to establish the presence or absence of certain important species. FWS has established specific field protocols for investigating sites for the presence of some threatened or endangered species and specific qualifications for field surveyors. Analysts can obtain information on suitable methods for surveying other important species from NMFS, FWS, State agencies, or from the scientific literature. Surveys should enumerate or estimate, where feasible, the numbers of individuals observed for Federally listed species, species proposed or that are candidates for federal listing, state- listed species, and species considered rare by the state. Aquatic Environmental Impact Analyses Professional judgment is necessary to determine the types of aquatic environmental impact analyses appropriate to an NRC decision or action. Analysts need to consult recent scientific literature and natural resource regulatory
