Ontario's old-growth forests are ecological marvels where dwarf cedars can live for over a thousand years, and centuries-old pine trees can grow a breathtaking 14 stories tall. Incredibly, many of these wonders are just a daytrip away.

The second edition of Ontario's Old-Growth Forests builds on the original guidebook, with detailed directions and maps for almost 70 old-growth forests throughout Ontario, including more forests in and around the GTA, and improved maps for all sites. It contains a wealth of information about the history and ecology of old-growth forests, and a revised chapter on the current state of old-growth forest conservation.

Michael Henry is the author of ONTARIO’S OLD GROWTH FORESTS. He is is a botanist and forest ecologist who has spent over two decades studying, writing about, and working to conserve Ontario's old-growth forests. He compiled and maintains the list of Ontario's oldest trees; he designed and constructed the Blueberry Lake Ecology Trails in Temagami; he confirmed that the Jackson Creek forest in Peterborough is an old-growth forest; and he has worked to protect threatened old-growth forests within Algonquin Park, where he and Nate Torenvliet found unprotected forest over 400 years old. He is currently working on a book about old-growth forests in Ontario's Greenbelt. Michael has also worked as a natural builder and is lead author of the book Essential Natural Plasters: A Guide to Materials, Recipes, and Use.

He has written numerous journal articles, technical reports, and educational pieces. He is most familiar with the forested landscapes of Algonquin and Temagami, located in central Ontario. He has held positions at a number of universities including the University of Pittsburgh and Wilfrid Laurier University. Currently, he is employed as a senior environmental scientist with Knight Piesold Ltd. in North Bay, Ontario, where he works primarily on environmental impact assessment projects in the Canadian arctic.
