This website is about forests in their natural condition. Ancient forests have never been cleared or transformed by humans; while old-growth forests have been free of disturbance (natural or human) long enough for trees to grow old. We discuss the definition of old growth forests in our post what is old-growth forest?
You can learn more about forest ecology, history, and threats, or read articles about old-growth forests, by reading our forest journal.
Explore old-growth forests in Canada and the U.S. using maps, or hiking and canoeing guides. Start your explorations using the map below, or check back in a few weeks when an improved version of this map and an old-growth forest database will be available.
