The Foundation for Deep Ecology, The Conservation Land Trust, and Conservacion Patagonica have offices at Fort Cronkhite in the Marin Headlands in Sausalito, California. Together, these organizations are dedicated to the preservation of wild nature.

In recent years, the Foundation for Deep Ecology has been active in publishing large-format books on diverse environmental topics. These include Wildfire: A Century of Failed Forest Policy, Fatal Harvest: The Tragedy of Industrial Agriculture, Welfare Ranching: The Subsidized Destruction of the American West, and Clearcut: The Tragedy of Industrial Forestry.

The Conservation Land Trust works to protect wildlands, primarily in Chile and Argentina. Pumalin Park, a project of the Conservation Land Trust, is comprised of more than 700,000 acres and functions as a national park under a private initiative. While most of the park is pristine wilderness, it has extensive public access and is a popular destination.

Created in 2000, Conservacion Patagonica has already placed 450,000 acres of critical Patagonian habitat into permanent protection. Conservacion Patagonica has successfully created one Argentine national park, and is in the process of creating a second in Chile.
