Anadromous Fish

Spending part of their lives in freshwater streams and part in the ocean, anadromous fish like coho salmon (Oncorhynchus kisutch), steelhead trout (O. mykiss), and threespine stickleback (Gasterosteus aculeatus) are good indicators of riparian habitat quality, hydrological conditions, and ocean health. Anadromous fish are also an important food source for many species, as well as a source of marine-derived nutrients for riparian communities.

The Overall Health of Mt. Tam's Fish

Endangered populations of coho salmon and threatened steelhead trout live in Redwood and Lagunitas creeks in the One Tam area of focus. The land management agencies on Mt. Tam and their partners have been monitoring these species for decades, counting adult spawners, estimating the number of juveniles, and (since 2006) monitoring smolts heading to the ocean. These long-term data sets provide ample information to make an assessment of the condition and trends of these species.
