One Tam: many ways to give back to the mountain that gives us so much

Community Science & Stewardship

Community Stewardship

Through its awe-inspiring landscape, rich biological diversity, and proximity to the communities that surround it, Mt. Tamalpais offers exceptional potential to connect people to the mountain and their natural surroundings. One Tam partners tap into this potential through programs that celebrate Mt. Tamalpais, inspire people, and engage them in the care of Mt. Tamalpais. From naturalist walks and talks, volunteer workdays, immersive summer high school programs, community science opportunities and internships for local youth, we aim to care for Mt. Tamalpais while engaging and deepening the community's relationship to the to the mountain.

The stewardship program, established in the spring of 2015, engages thousands of individuals each year from all walks of life, with a particular focus on under-represented communities and youth. Relationships developed through these programs will provide a foundation for community dialogue, increased public awareness, and support for Mt. Tamalpais that will extend our legacy of conservation and endure through the generations.

Community Science

One Tam's community science program blends landscape-scale science with community engagement and education. Community members participate in large-scale studies to inventory and monitor natural resources in the Mt. Tamalpais region, helping to fill gaps in our knowledge about local natural resources. These volunteer programs are an opportunity to learn new skills and to connect to our local public lands through participating in science. Current programs include Marin Wildlife Watch, Tamalpais Bee Lab, and bioblitzes (check our calendar for opportunities).
