Native Species

Status of 32 kinds of salmon, steelhead, and trout

The science-based report is clear - if we don't act, we risk losing our native salmon, steelhead and trout species.

45% of species are likely to be extinct in the next 50 years if present trends continue.

This includes 11 of 21 anadromous species (52%) and 3 of 10 of its inland species (30%).  Under present conditions, 23 of the remaining 31 species (74%) are likely to be extinct in the next 100 years.

The SOS II report recognizes 32 distinct salmonids in California: one for each kind of native salmon, steelhead, and trout.  Of these salmonids, 22 are endemic to California and only five are shared with neighboring states.

Each account has been distilled from comprehensive, peer-reviewed life history accounts and scoring rubrics prepared by Dr. Peter B. Moyle, Dr. Robert Lusardi, and Patrick Samuel, and will be published as Salmon, Steelhead, and Trout in California: Status of Emblematic Fishes, Second Edition. Readers interested in learning more about the diverse salmonid species in California, report methods, science underlying the scoring in the accounts, and obtaining references for further reading should review the full report.
