One Mountain, One Team

With its sweeping views, miles of trails, and ancient forests, Mt. Tam is a beloved local treasure. But the mountain also faces many challenges such as invasive weeds, forest diseases,
and the effects of climate change. 

One Tam transcends boundaries to inspire deep connections to Mt. Tam and to mobilize the skills and resources of our five partners and the community to care for its long-term health.

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