Ecology
The Petaluma River Watershed hosts several federally endangered animals including the Salt marsh harvest mouse (Reithrodontomys raviventris), Peregrine Falcon (Falco peregrinus anatum), California Clapper Rail (Rallus longirostris obsoletus), Winter-Run Chinook salmon (Oncorhynchus tshawytscha). Endangered flora include Soft Bird’s-Beak (Cordylanthus mollis ssp. mollis), Baker’s Stickyseed (Blennosperma bakeri), Burke’s Goldfields (Lasthenia burkei), Showy Indian clover (Trifolium amoenum), Sebastopol meadowfoam (Limnanthes vinculans).
The Steelhead trout (Oncorhyncus mykiss) that spawn and rear in the Petaluma River watershed are wild, not hatchery, stock. Chinook are seen in the main stem of the Petaluma River and The United Anglers of Casa Grande High School have seen chinook at the turning basin, near the Lynch Creek confluence. The high school students constructed a salmonid hatchery in 1993 and in 2002 74 Chinook salmon returned to spawn in the Adobe Creek tributary.
