The Mt. Tamalpais watershed is home to 400 species of wildlife, and includes rare, threatened, and endangered species. We are committed to sustaining the ecological health and biological diversity of the watershed, with programs to monitor wildlife such
as the northern spotted owl, osprey, the yellow-legged frog and the western pond turtle.

Long-term monitoring is an important tool in wildlife conservation as it provides a wealth of useful information about ecosystem health, species presence, and population trends over time. The district supports long-term monitoring programs for a number of wildlife species. The district has also conducted a limited number of targeted inventories, short term surveys designed to determine the presence or absence of target species.

Marin Water is fortunate to have strong community partnerships that help us care for our watershed. We work together through volunteer programs, educational programs with our local schools, and partnerships like One Tam—a coalition of agencies working to preserve and protect Mt. Tamalpais that includes Marin Water, the National Park Service, California State Parks, Marin County Parks, and Golden Gate National Parks Conservancy.
