Berryessa Snow Mountain National Monument


The Berryessa Snow Mountain area is the heart of northern California’s wild Inner Coast Range. Once covered by ocean waters, it is a landscape shaped by geologic forces of staggering power overlain with bountiful but fragile biodiversity.

In 2015, President Barack Obama permanently protected 330,780 acres of federal public land in order to preserve its prehistoric and historic legacy and maintain its diverse array of scientific resources, ensuring that the prehistoric, historic, and scientific values remain for the benefit of all Americans. In 2024, President Joseph Biden expanded Berryessa Snow Mountain National Monument to include Molok Luyuk, a rugged ridge on the border of Colusa and Lake County. MORE

In October, Tuleyome hosted a community walking tour showcasing Mare Island’s southwestern coastal wetlands, a notable potion of the six distinct parcels proposed to be included in The San Pablo Bay National Wildlife Refuge Expansion Act. By law, National Wildlife Refuges overseen by U.S. Fish and Wildlife Service (USFWS), are legally mandated to conserve migratory bird and endangered species habitat while allowing for public access and recreation compatible with those mandates. This boundary expansion legislation is expected to be introduced in the 119 th Congress by Representative John Garamendi (D-CA-08), Jared Huffman (D-CA-02) and Mike Thompson (D-CA-04) and Senator Alex Padilla (D-CA). Approximately 6,934 new acres would be included in the boundary expansion. The boundary expansion aims to enhance the existing refuge’s 24,390 acres of essential wetland habitats along the coastlines of Sonoma, Solano, and Napa Counties. These tidal marshes, mud flats, and seasonal wetlands all host migratory birds, small mammals, and form the nursery grounds to sensitive fish species. Some iconic species include the California clapper rail, salt marsh harvest mouse, San Pablo song sparrow, and Suisun shrew. Current owners of the parcels that are proposed to be included within the refuge boundaries are the State Lands Commission, the State Coastal Conservancy, and the Sonoma Land Trust, all who support the proposal.

It’s been a decade since the Berryessa Snow Mountain National Monument was designated in 2015, and just last year we celebrated the expansion of the Monument to include Molok Luyuk. Now we’re in an exciting new phase: working alongside our community to shape how this incredible landscape will be protected for generations to come. Throughout 2025, Tuleyome has been collaborating with the Bureau of Land Management to submit detailed information about the many “objects of interest” that make our National Monument so special, from unique soils, to native plants, breathtaking geology and the rich cultural heritage of the indigenous people who have called this plan home for thousands of years. This information will help BLM develop the Monument’s resource management plan. But we’re not stopping there. We’re doing something that reflects the very best of what public lands protection can be: we’re creating a Community Alternative Management Plan (CAMP).
