The mission of the San Juan Preservation Trust is to preserve and protect open spaces, scenic views, forests, agricultural lands, habitats, watersheds, riparian corridors, wetlands and shorelines in the San Juan Archipelago.

Founded in 1979, the San Juan Preservation Trust is a private, nonprofit land trust dedicated to helping people and communities conserve land in the San Juan Islands of Washington State. Together with our landowner partners, the Preservation Trust has permanently protected more than 300 properties, 47 miles of shoreline, and 18,000 acres on 20 islands, including land now managed as public parks, nature preserves, wildlife habitat, and working farms and forests.

First accredited by the Land Trust Alliance Accreditation Commission in 2012, the Preservation Trust successfully renewed its prestigious “Accredited” mark of distinction in 2017 for another five-year term.
