Marin Open Space Trust works to preserve Marin’s most important
remaining open space lands at risk of development.

Thank you for passing Measure A. Your support protects and maintains parks, open space and farmland right here in Marin County – without increasing tax rates!

Marin Open Space Trust preserves open space by purchasing and receiving donations of land and conservation easements. We work collaboratively with parks agencies and other local land conservation organizations. Please contact us about any potential open space projects.
