Marin Audubon Society (MAS) is one of the most respected environmental organizations in Marin. Our commitment to protect valuable habitat and endangered species is second to none.

We began restoring wetland habitat in 1985 and started an active program of acquiring wetlands in the mid 1990’s. These efforts provide natural habitat for native wildlife, flood protection, improved air and water quality, education and recreation opportunities. The permanent protection of at risk wetland and adjacent upland habitats also serves to expand populations of birds and other wildlife.

MAS owns and manages more than 500 acres on 25 parcels throughout Marin, stretching from Mill Valley to Novato. We have deeded significant acreage to the California Department of Fish and Wildlife and to Marin County Open Space District, and we will continue to donate additional acreage to these agencies for long-term protection and management.   With our partner Marin Baylands Advocates, we are currently focusing on acquiring a parcel that is part of the Corte Madera marsh habitats.

Our dedicated group of volunteers maintains habitats on properties we own at Bahia in Novato, Petaluma Marsh and Simmons Slough in unincorporated Novato, Triangle Marsh in Corte Madera, and Arroyo Corte Madera in Mill Valley.

As strong supporters of citizen science, we sponsor three Christmas Bird counts: Southern Marin, Pt. Reyes and Cheep Thrills in Northern Marin. Our annual programs include 10 presentations by experts in their field, focused on bird identification and habitat, field trips to such special places as the Farallon Islands, the Wildlife Refuge near Sacramento and the Delta, as well as local sites. We also offer a birding class conducted by Meryl Sundove and Roger Harris and sponsor Junior Bird Watchers. Our outstanding newsletter The Clapper Rail is published ten times a year.

MAS advocates for wildlife locally as well as regionally by participating in meetings, commenting on management and planning documents, and constant attention to any development threats to Marin’s priceless resources.  MAS provides its members and the public many opportunities to enjoy, protect and restore the natural habitat of Marin County and beyond.
