"In February 1994, the National Marine Fisheries Service (NMFS) received a petition seeking protection under the Endangered Species Act (ESA) for 178 populations of steelhead (anadromous Oncorhynchus mykiss) in Washington, Idaho, Oregon, and California. At the time, NMFS was conducting a status review of coastal steelhead populations (O. m. irideus) in Washington, Oregon, and California. In response to the broader petition, NMFS expanded the ongoing status review to include inland steelhead (O. m. gairdneri) occurring east of the Cascade Mountains in Washington, Idaho, and Oregon. This report summarizes biological and environmental information considered by the Biological Review Team (BRT) that conducted the West Coast Steelhead Status Review"--Exec. summary.
