What Sonoma County AG + Open Space does

Sonoma County Agricultural Preservation & Open Space District (operating as Ag + Open Space) is a special district of the County of Sonoma, California, established by voter approval in 1990 and reauthorized in 2006, with a statutory mandate to permanently protect agricultural, natural-resource, water, and scenic open-space lands within Sonoma County. The district delivers its mandate through a portfolio of programs rather than commercial products: a Conservation Easement Program that places perpetual deed restrictions on willing private landowners; a Community Spaces Matching Grant Program that funds urban parks, restoration, and recreation projects through cities, public agencies, and nonprofits; a Vital Lands Initiative long-term strategic plan; a Stewardship Assistance Program delivered in partnership with Sonoma and Gold Ridge Resource Conservation Districts; and a Buy-Protect-Sell Pilot aimed at lowering land-access barriers for farmers and ranchers.

The organization is funded primarily by a voter-approved quarter-cent sales tax that generates ongoing, dedicated revenue for land acquisition, easement purchases, and stewardship. It supplements tax receipts with competitive state and federal grants (California Strategic Growth Council, USDA NRCS RCPP, California Coastal Conservancy, Wildlife Conservation Board) and private foundation support. Core "technology" is the conservation easement legal framework and land-acquisition pipeline, supplemented by conservation planning, habitat assessment, and strategic prioritization tools under the Vital Lands Initiative. Since inception, the district has conserved over 127,000 acres, including 60 parks and preserves, 77 farms and ranches, 143 miles of salmonid streams, and more than 80,000 acres of redwood and oak woodlands, with conserved lands transferred to Sonoma County Regional Parks or local cities for long-term management and public access.

Direct peers

• Peninsula Open Space Trust (POST): Bay Area nonprofit land trust protecting agricultural, scenic, and natural lands through fee acquisition and easements; closely analogous mission, geography, and instruments, with a comparable post-perpetual stewardship obligation.
• Sonoma Land Trust: A core operating partner that co-acquires and stewards conserved properties in Sonoma County (Pole Mountain, Jenner Headlands, Weeks Ranch). Same geographic market and same easement-based model, but structured as a 501(c)(3) nonprofit rather than a government district.
• Napa County Land Trust: Adjacent-county California land trust using conservation easements to protect vineyards, ranches, and natural habitat; same North Bay agricultural conservation model and overlapping ecosystem priorities.
• Santa Clara Valley Open Space Authority: Independent special district in Santa Clara County using voter-approved funding to conserve natural and working lands; same California special-district governance structure, easement program, and stewardship mandate.
• Midpeninsula Regional Open Space District: Independent special district in the Bay Area that acquires and manages open space for public use; functionally analogous entity type and revenue model (tax-funded public agency holding conservation real estate), making it a near-direct structural peer.
• Marin Agricultural Land Trust (MALT): County-level agricultural land trust in Marin County, California using permanent conservation easements to protect working farms and ranches—same legal instrument, same agricultural preservation mandate, and adjacent geography to Ag + Open Space.

Broad incumbents

• The Trust for Public Land: National nonprofit that facilitated the Kashia Property acquisition and partners on multiple Sonoma transactions; substantially larger scope and budget than Ag + Open Space but uses the same conservation easement and land acquisition toolkit.

Emerging players

• Save the Redwoods League: Statewide nonprofit that led acquisition of the 1,517-acre Monte Rio Redwoods with Ag + Open Space as a partner; partial overlap on redwood and coastal forest protection but more narrowly focused on redwood lands rather than whole-county conservation.

Others

• Land Trust Alliance: National membership association representing land trusts including Ag + Open Space-style entities; not a direct competitor but the governing body whose accreditation standards and federal-policy advocacy shape the operating environment for all Sonoma County easement holders.

Regional players

• Mountains Recreation and Conservation Authority: California joint powers authority managing conserved lands and parks in and around Los Angeles; comparable government-agency structure focused on park and open space administration but operating in a very different geography.
