Old-growth forests in Ontario are incredibly varied, from thousand-year-old cedars that hang from cliffs to pine trees towering over 13 storeys tall. Written by Mike Henry and Peter Quinby, Ontario's Old-Growth Forests is a guidebook that leads explorers through these tree colonies with maps and directions, while providing readers with a deep understanding of old-growth forest ecology.

The long-anticipated second edition is now available. This edition introduces more sites in southern Ontario, including urban old-growth forests, existing only a bus or bike ride from millions of people. Also included is an expanded chapter on forest conservation, which offers solutions in the face of today's many threats to our forests.
