Over the past six decades, volunteers have shared their love of nature with generations of schoolchildren, cleared trails, removed invasive plants, become field observers, maintained trail cameras, led tours, managed the M.F.K. Fisher Last House library, and even sung in a choir. ACR would be nowhere without its volunteers!

Join us today and start connecting with the beauty of our preserves, make new friends, and know you are helping protect the wildlands and wildlife of Marin and Sonoma counties.
