Welcome to the Great Lakes Silviculture Library

The Great Lakes Silviculture Library was conceived with the idea that every silviculture treatment is an experiment, every forest manager both a teacher and a learner. This site is designed to help forest managers from Michigan, Minnesota, Ontario, and Wisconsin exchange silviculture prescriptions and outcomes of actual on-the-ground management activities.
