There is so much about Mount Tamalpais that binds us. Now we’ve launched an approach to the care and stewardship of the mountain that is just as unifying and all-embracing: the Tamalpais Lands Collaborative (TLC).

At 270 acres, Tennessee Hollow is the largest watershed in the Presidio. Since the late 1990s, the Presidio Trust, National Park Service, and Parks Conservancy have been working toward restoring the entire watershed from springs to bay, to restore a vibrant, contiguous, and diverse mosaic of native plant communities and wildlife habitat.

The Park Stewardship program has focused on removing invasive plants to restore the Mission Blue butterfly habitat at this site in Marin County.
