Welcome to Marin Audubon Society
For more than 50 years Marin Audubon has worked to protect wildlife habitat in Marin, sometimes stepping in to buy land that is slated for development. We need your help today to purchase a 5.2 acre property that will fill a critical gap in the 300 acre Corte Madera Ecological Reserve.
MAS also provides its members and the public many opportunities to experience the birdlife and nature of Marin County and beyond through Field Trips and Events, our monthly MAS newsletter The Clapper Rail, and the annual Christmas Bird Counts. For a listing of many of our activities and events please check our Calendar.
After 20 years of negotiation, Marin Audubon Society has reached an agreement to purchase a critical 5.2-acre former tidal marsh that is key to the survival of the endangered Ridgway's Rail (formerly California Clapper Rail) and other wildlife. This campaign will protect and restore, in perpetuity, coastal wetlands in the Corte Madera Creek watershed, filling a critical gap in the 300-acre Corte Madera Ecological Reserve. The Ecological Reserve includes one of the few marshes around the Bay that has never been diked, as well as 200 acres of restored marsh. Ancient marshes have complex channel systems and vegetation, and support greater diversity and numbers of wildlife. These rare and valuable characteristics will be protected, enhanced and expanded by this acquisition.
Update August 2015 - Thank you to our donors!
As of early August, we have received funds and pledges for the full purchase amount of $1,075,000. Many, many thanks to our donors and to government agencies who have responded to our call. This five-plus acre parcel is an integral piece of the remaining marshland in Central Marin. We look forward to updating you as we move ahead to restore the tidal marsh and create upland refugia for an important population of endangered Ridgeway’s Rail, as well as other wildlife that inhabit the Corte Madera Ecological Reserve.
Surrounded by development, the Corte Madera marshlands are critical wildlife habitat as well as a buffer against sea level rise. The new acquisition is the smaller of the two filled and bright green parcels. Photo by Robert Campbell.
