With its sweeping views, miles of trails, and ancient forests, Mt. Tamalpais is a beloved local treasure. But the mountain also faces many challenges such as invasive weeds, forest diseases,
and the effects of climate change.
The One Tam partnership mobilizes the resources of the National Park Service, California State Parks, The Marin Municipal Water District, Marin County Parks and Golden Gate National Parks Conservancy to ensure a vibrant future for Mt. Tamalpais.
A bioblitz is a quick, intense survey of the species present.
