Species Ranges - Salmon and Steelhead (all West Coast)

Maps and GIS data

Salmon and steelhead range data can be downloaded as geodatabases, viewed interactively in the Protected Resources App, or accessed through map services (REST URLs).

These range data represent the locations of Endangered Species Act (ESA) listed entities called steelhead Distinct Population Segments (DPSs) and salmon Evolutionarily Significant Units (ESUs). Ranges are depicted using watershed polygons that circumscribe important spawning, rearing, and migration habitats. If ESA-listed salmon or steelhead are found outside of these boundaries, they are still protected.

Listed entity text descriptions and Federal Register (FR) document citations for listing determinations can be viewed in the electronic Code of Federal Regulations (eCFR) for threatened and endangered species.

The 2015 geodatabase was created to standardize geospatial data for salmon and steelhead listed under the Endangered Species Act. The extent is Washington, Oregon, and Idaho, with some data in British Columbia, Canada. This product integrates DPS/ESU boundary data with population boundary data (defined by Technical Recovery Teams). The zip file also contains a schema diagram (PDF), that documents the gdb structure, fields, and values. The main object in the gdb is the "fish" feature class, which can be queried and symbolized on a map. The fish feature class includes overlapping polygons due to the complexity of salmon and steelhead data (overlapping ranges, multiple run times, etc.).

The 2013 geodatabase extent is California and a portion of southern Oregon. This product includes DPS/ESU boundary data, but does not have population boundary data (defined by Technical Recovery Teams).
