Protected Resources App

Displays spatial data for marine and anadromous species listed under the Endangered Species Act (ESA) in the West Coast Region. The core datasets are ESA-listed species’ ranges and critical habitat.

ESA-Listed Species’ Ranges - Under the Endangered Species Act, the term “species” can refer to a taxonomic species, subspecies, Distinct Population Segment (DPS), or an Evolutionarily Significant Unit (ESU) for a DPS of Pacific salmon. Salmon ESUs and steelhead DPSs are depicted as ranges using watershed polygons that circumscribe important spawning, rearing, and migration habitats.

ESA Critical Habitat - ESA critical habitat is depicted as lines to represent protected rivers and streams and as polygons to represent protected waterbodies, marine areas, estuaries, and marshes.

These datasets are intended to assist the public and our partners with visually interpreting federal regulations. However, these data do not constitute legal definitions. Please refer to NOAA Fisheries’ Federal Register rules and the electronic Code of Federal Regulations (eCFR) for legal definitions of threatened or endangered species and critical habitat.
