ional interest and may provide recommended survey timings and protocols specific to such species. For certain species, the agencies may request that uniquely qualified specialists conduct the surveys. Examples of potentially useful sources of information include the following: • recovery plans that FWS, NMFS, or State wildlife agencies prepared for listed species • habitat conservation plans that have been approved by FWS or NMFS • fishery landings data • government ecological reports • academic theses and dissertations • surveys conducted at nearby facilities, such as parks, research reserves, and institutional properties containing habitat types similar to those in the area to be surveyed • surveys conducted and databases maintained by non-governmental conservation and other organizations • field guides with range maps indicating species that could potentially occur in a geographic area Existing inventory data collected from the survey area may serve as a baseline for new field surveys in areas where the habitat has not changed substantially. When supplementing existing data, the analyst should consider the spatial extent, purpose, and techniques of the original data collection. Consideration of these factors may identify certain locations and groups of plants and animals omitted during the original data collection effort that should be surveyed. Existing site-specific data that no longer reflect current conditions (e.g., a habitat has substantially changed or species distribution has shifted) and areas without existing data will require reconnaissance surveys for planning purposes, followed by detailed field surveys. Fauna surveys should employ standard techniques suitable for the DG-4023, Page 15 detection and identification of the category of wildlife (i.e., mammals, reptiles, fish, and invertebrates) and any life stages of interest. Analysts should choose survey methods appropriately based on targeted species and life stage to be assessed. They
