Tongass National Forest

The Tongass National Forest /ˈtɒŋɡəs/ in Southeast Alaska is the largest national forest in the United States at 17 million acres (69,000 km). Most of its area is part of the temperate rain forest WWF ecoregion, itself part of the larger Pacific temperate rain forest WWF ecoregion, and is remote enough to be home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains. An international border with Canada (British Columbia) runs along the crest of the Boundary Ranges of the Coast Mountains. The forest is administered from Forest Service offices in Ketchikan. There are local ranger district offices located in Craig, Hoonah, Juneau, Ketchikan, Petersburg, Sitka, Thorne Bay, Wrangell, and Yakutat.
