Protect and sustain the unique lands, waters, and biodiversity of West Marin. 


Our work strives to provide long-term protection and conservation of the unique ecosystems and rural communities of West Marin, and serves as a foundation of environmental protection for future generations.

Guiding Principles


Use grassroots strategies to research and publicize local environmental issues facing our community to inform, empower, and educate stakeholders and our members.


Respect the complex ecology and intrinsic value of the natural world.


Partner with local communities, organizations, governments, businesses, and members to ensure maximum public participation around local environmental issues.


Provide opportunities to learn about the environment through events, community workshops, outreach, and publications. 


Engage our community in activities that promote a healthy environment, including stewardship through membership, events, citizen science and volunteer opportunities. 


Use science, law, and policy to make ethical decisions around complex environmental issues in a dynamic environmental and political landscape.

Not every place is fortunate enough to have its own environmental watchdog. Here in West Marin we do, but only for as long as we ensure that it continues.
