Marin Open Space
Marin Open Space Trust

MOST is an independent non-profit organization that works with individuals, organizations, and governmental agencies to acquire and protect open space in Marin County.



Fairfax Open Space
Fairfax Open Space Committee

FOSC is our sister organization in Fairfax, founded in 2004. Since we share common goals and some of the properties we are trying to protect lie on the borders between Fairfax and San Anselmo, the two OSC’s have worked closely together and coordinated our efforts since their inception.


Friends of Corte Madera Creek
Friends of Corte Madera Creek Watershed

The Friends works throughout the Ross Valley to protect the watershed, ensure water quality, and encourage the aquatic life of the streams. Since this involves maintaining clean runoff and natural filtration of the water, they support our efforts to preserve open space in the Ross Valley.
