The largest remaining intact part of an 1843 Mexican land grant in California’s Cuyama Valley has been permanently protected from future commercial development after a successful grassroots conservation campaign. The 5,650-acre Spanish Ranch, managed by the Doiron family, is now protected by a permanent agricultural conservation easement through a partnership with the California Rangeland Trust. The agreement was completed after a $1 million fundraising campaign.
The project protects a continuous farming and ranching tradition that began before California became a state, according to an official announcement from the California Rangeland Trust. The agreement guarantees that the historic cattle ranch will remain working agricultural land forever, preventing future subdivisions or industrial development. It protects important wildlife corridors, native oak forests, and headwater habitats across San Luis Obispo and Santa Barbara counties.

To pay the remaining costs, the California Rangeland Trust launched a $1 million fundraising campaign. More than 140 private donors and seven charitable foundations gave money to the campaign, providing nearly 54 per cent of the project’s total funding. The organization now protects more than 150,000 acres of working land across Santa Barbara and San Luis Obispo counties, according to records published by the California Rangeland Trust. This represents 34 per cent of its conservation portfolio across the state.

Protecting the land required money from several sources, including federal grant programs, charitable foundations, and individual donors. Federal support came from the United States Department of Agriculture’s Natural Resources Conservation Service through its Agricultural Conservation Easement Program. The program provides matching funds to protect working agricultural land. A major leadership grant from the John S.

“Spanish Ranch represents what is possible when landowners, conservation partners, and communities come together around a shared vision for the future,” Delbar stated. “We are not just conserving acres, we are helping ensure that these working landscapes remain whole, productive, and connected for generations to come.” Beyond its historical value, Spanish Ranch provides an important natural buffer between the Los Padres National Forest and the Cuyama River basin. The property offers important habitat for native wildlife, including the California condor, tule elk, pronghorn, and several species of special concern. Under the legal agreement, the Doiron family keeps full private ownership and control of the cattle ranch. However, the easement permanently removes all future commercial development rights. This ensures that the soil, watershed, and vegetation can remain protected. Michael Delbar, Chief Executive Officer of the California Rangeland Trust, pointed to the wider importance of the agreement for protecting land in the region.
