It’s through community support that Mt. Tamalpais has been protected for 100 years, and it’s through One Tam that we can protect and steward it for 100 more. But we need your help. Individuals, community organizations, and local businesses can all help support our restoration, stewardship, and education efforts.
Share your time and talents with Mt. Tamalpais! One Tam supports the volunteer efforts of all of our partners and also offers a number of special opportunities to give back to the mountain that gives us all so much.
Teaching and inspiring future Mt. Tamalpais stewards and supporters is essential if we are to continue its long legacy of community care. One Tam youth programs use the mountain as a diverse and expansive classroom to teach young stewards restoration practices, science, and leadership skills, and to create meaningful experiences that will last a lifetime.
Mt. Tamalpais’ diverse wildlife, important habitats, and much-loved trails are the focus of a wide array of restoration and stewardship work. One Tam brings together the expertise and resources of its partners with additional funding and community support to protect, restore, care for Mt. Tamalpais in a way that none of us could do alone.
Mt. Tamalpais is an ecological treasure trove; however, climate change, invasive species, forest diseases, and other challenges affect its plants, animals, water, and air. While we all have a role to play in helping keep this place healthy and resilient, how do we know what we need to do? In 2016 a team of scientists and managers came together to find out: how healthy is Mt. Tamalpais? Discover what they learned.
Landscape-scale stewardship is how we work together across boundaries to care for the places we love, enjoy, and depend upon, and how we continue to renew and sustain these places for current and future generations. The One Tam partnership embodies this approach by creating a more seamless network among Mt. Tamalpais’ land managers. Learn more about how we are going further together.
