What Marin Audubon Society Inc does

Marin Audubon Society Inc is a 501(c)(3) nonprofit environmental conservation organization founded in 1956 and based in Mill Valley, California. Its mission is to conserve and restore natural ecosystems with a focus on birds, other wildlife, and their habitats in Marin County and the broader San Francisco Bay Area. Over more than 60 years, the organization has acquired more than 1,000 acres of Marin County land — currently retaining direct ownership of roughly 500+ acres of wetlands and associated uplands — through a combination of purchase, donation, and tax-default acquisition, while transferring portions (228 acres to Marin County Open Space District, 362 acres to California Department of Fish and Wildlife) to permanent public stewardship.

The organization's core activities are property acquisition, tidal marsh restoration (five major projects completed to date, including the 632-acre Bahia restoration in 2003 and the Corte Madera Marsh Ecological Reserve in 2017), and conservation advocacy. It runs a community-led engagement program including guided field trips throughout Marin County and to the Farallon Islands, a monthly speaker series, three annual Christmas Bird Counts, and volunteer workdays for habitat enhancement, invasive species removal, and native plant installation. There is no proprietary technology product; the organization is volunteer- and staff-light (1–10 employees) and depends heavily on member labor for stewardship.

Revenue is generated through a mix of annual chapter membership dues, individual donations and bequests, foundation and government grants (with the California State Coastal Conservancy as the dominant institutional funder, including $5.8M+ in 2003 and $2M in 2024), AmazonSmile referral donations, and small field-trip/event registration fees. The organization is an independent chapter within the National Audubon Society network, governed by its own Board of Directors, and does not have a parent company, venture backing, or public listing.

Scale indicators7 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• The Nature Conservancy (California): Large national conservation NGO with California operations covering land acquisition, restoration, and policy. Operates at vastly greater scale but follows the same habitat-protection playbook.
• Ducks Unlimited: National nonprofit focused on wetland and waterfowl habitat conservation. Highly comparable mission around tidal marsh restoration and migratory bird habitat, but at national scale.
• Audubon California: State-level Audubon affiliate that channels funding (e.g., Orvis grants) to chapters and runs California-wide conservation programs. Provides capital, policy, and brand infrastructure to chapters like MAS.

Regional players

• San Francisco Baykeeper: Bay-wide nonprofit focused on wetland and water quality protection in San Francisco Bay. Operates in overlapping geography with overlapping wetland-habitat mission.
• California Native Plant Society: Statewide nonprofit focused on native plant conservation, habitat restoration, and volunteer stewardship. Comparable volunteer-driven model and overlap on habitat restoration projects like native planting at Corte Madera.
• Marin Conservation League: Marin County environmental advocacy nonprofit historically active in land-use and baylands protection. Comparable scale and geography; complementary rather than duplicative mandate.
• Madrone Audubon Society: Sonoma County Audubon chapter with similar field-trip, membership, and conservation programming. Geographically adjacent to Marin and operating an essentially identical chapter model.

Emerging players

• Point Blue Conservation Science: Bay Area-based conservation science nonprofit running citizen-science programs (similar to MAS's Christmas Bird Counts) and applied habitat research. Similar Bay Area footprint and science-driven mission.

Direct peers

• Golden Gate Audubon Society: San Francisco-based Audubon chapter offering field trips, conservation advocacy, and habitat protection programs. Closest direct comparable: same chapter model, same parent network, overlapping Bay Area geography.
• Santa Clara Valley Audubon Society: Bay Area Audubon chapter running field trips, speaker series, and habitat restoration. Closely comparable mission, programming mix, and member-based nonprofit structure.
