Sonoma County has a lot of native wildlife to enjoy!  (see list below)

While all of our native wildlife is important, there are a few species that are of particular concern as their numbers are low enough to result in being classified as endangered or threatened.

 

Endangered

Behren’s Fritillary

Myrtle’s Silverspot

California Freshwater Shrimp

Coho Salmon

Tidewater Goby

California Tiger Salamander

California Clapper Rail

Salt marsh harvest mouse

 

Threatened

Chinook Salmon

Steelhead

California Red-Legged Frog

Snowy Plover

Western Snowy Plover

 

 

More coming soon!

We will group species based on habitats throughout Sonoma County, add more details and pictures of each, and add some invertebrates. In the meantime, here is a list of vertebrates in the County.

This list is a work in progress. Please contact us if you see something that needs to be added or removed.
