Together, ensuring a vibrant and healthy future for Mt. Tam

 

What We Do

What We Do

Who We Are

 

The open spaces on Mt. Tam are a mosaic of interlocking protected areas primarily managed by four public agencies: the Marin Municipal Water District, National Park Service, California State Parks, and Marin County Parks.

 

These agencies have the honor of protecting some of the most beautiful, ecologically rich, and well-loved open spaces in the region, and an important source of drinking water for Marin County residents.

 

One Tam brings these four agencies together with the nonprofit Golden Gate National Parks Conservancy to leverage the skills and resources each partner and inspired community members to support the long-term stewardship of Mt. Tam.

California State Parks

Mount Tamalpais State Park, one of 280 units under the California Department of Parks and Recreation, encompasses 6,300 acres of land on Mt. Tam.

What We Do

Like the plants and animals that live here, most people view Mt. Tam as a single, interconnected place. One Tam offers a coordinated approach that allows the mountain’s land managers to work together in a way that reflects this holistic view, and builds on the community’s long history of conservation, stewardship, and giving.

One Tam’s science and restoration work also help us understand and protect the mountain’s long-term health. Our volunteer programs engage people of all ages in caring for its treasured resources. And membership opportunities renew the spirit of philanthropy that has been so fundamental to the preservation of Mt. Tam over the past century.

Mt. Tam 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. Tam? Discover what they learned.

Is Mt. Tam in Peak Health?

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. Tam’s land managers. Learn more about how we are going further together.
