Founded in 1979, the San Juan Preservation Trust is a private, non-profit land trust dedicated to helping people conserve land in the San Juan archipelago. Noted for its $18.5 million acquisition of Turtleback Mountain on Orcas Island, the organization has permanently protected more than 240 properties, 30 miles of marine shoreline, and 13,000 acres on 18 islands, including land now managed as public parks, private nature reserves, and working farms and forests.
