Turtle Observer Program

The western pond turtle, Actinemys marmorata, is a federally listed vulnerable species. These are the only fresh water turtles native to California, and they can be found around Phoenix, Lagunitas, and Alpine Lakes in the Mt. Tamalpais Watershed.

MMWD has enlisted the help of volunteers to protect this vulnerable animal by monitoring habitat conditions, recording their behavior, and educating the public during the spring when they are most vulnerable. Volunteers have collected valuable data on native and non-native turtles that is helping to direct the management of these species.
