Salmon and Steelhead Ranges

August 22, 2019

Spatial data (zipped geodatabase) to be downloaded and used in a geographic information system (GIS). Metadata is included within the gdb. The zip file also contains a schema diagram, in pdf format, 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 salmon and steelhead range geodatabase can be viewed interactively in the Protected Resources App or accessed through a REST map service. 


This geodatabase was created in 2015 to standardize geospatial data for salmon and steelhead listed under the Endangered Species Act. The extent is NOAA Fisheries' West Coast Region, with some data in British Columbia, Canada. This product integrates DPS/ESU boundary data with population boundary data (defined by Technical Recovery Teams).

*More ranges and populations will be added to this gdb over time as data are standardized and integrated.
