Ancient Forest Exploration and Research

This website is about forests in their natural condition; including what we can learn from them, and threats that they face. 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.

You can learn more about forest ecology, forests threats, or read articles about old-growth forests, on our blog.

Learn about conservation corridors, old-growth white and red pine forests, and ancient forest landscapes in Ontario, from our research page or our publications.

Or explore old-growth forests in Canada and the U.S. using our database, which includes maps, directions, hiking and canoeing guides, and ecological information. Start your explorations using the map below.
