West Peak Restoration

One Tam has begun an 18-month study of restoration alternatives for Mt. Tam's West Peak, the goal of which is to understand technical constraints and opportunities related to the restoration of natural habitats and processes. This will serve as the basis for developing eventual alternatives for MMWD and public review. Visit the West Peak page to learn more about this special site and ways you can participate in the process.


New Library Parks Pass Program

The County of Marin, Marin County Free Library, and One Tam are partnering on a new program that increases access for residents for whom entrance fees may pose a barrier to visiting parks. Library card holders can check out a pass for free entry to beautiful local parks, and a backpack full of information to help explore them. Available at all 10 branches of the Marin County Free Library and Bookmobile starting April 9.

Conservation Science

New Work Studying Pollinators Underway

Stemming from the Mt. Tam Science Summit held last fall, MMWD and San Francisco State University are set to begin inventorying pollinators, primarily bees, on the mountain this spring. This will be the first time this part of Marin has ever been surveyed for pollinators. The field season should start at the beginning of March, but may be delayed by rain. There will be a number of opportunities to volunteer with this project, including specimen processing events. Stay tuned on

New Inventory of Mt. Tam's Bats Begins

One of the information gaps identified during the 2016 Mt. Tam health assessment was that we don’t know very much about bats on the mountain. Marin potentially supports up to 16 species of bats. This year’s study includes a number of components that will increase our understanding of bats and their ecology in Marin, and will employ several sampling methods including acoustic monitoring and mist netting. Information collected will include bat activity and species identification. The overarching goals of the study are to understand the relationships of bats and bat diversity to the landscape, the distribution of reproductive bats, and to provide insights on roosting ecology and roost selection in both summer and winter. This kind of data will contribute to our understanding of the diversity, health, and distribution of bats in the region, and inform management around protecting these species from disease.
