Ancient Forest Exploration and Research

CRW_2821This 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.

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