Managing timber to promote sustainable forests: a second-level course for the Sustainable Forestry Initiative of Pennsylvania

At least 80 percent of the raw material used for wood products by the forest industry is from privately owned woodlands. This publication provides material for a course designed to help landowners, foresters, and loggers work together to assess whether a planned timber harvest will retain the diversity of species on site. It includes methods for collecting overstory and understory data, inspecting these data, and assessing sustainability.
