The Old-Growth Forest Network is the only national network in the U.S. of protected, old-growth, native forests where people of all generations can experience biodiversity and the beauty of nature.


Our Work

Identify and Preserve

Our goal is to locate and designate at least one protected forest in every county in the United States that can sustain a native forest. We estimate that to be approximately 2,370 out of 3,140 total counties. To achieve this aim we work to identify forests for the Network, ensure their protection, and inform people of the forest locations. We are building not only a network of forests, but also an alliance of people who care about forests.
