This silvicultural guide is one of several, each of which provides a description of the silvicultural characteristics of the working group species and describes silvicultural practices for the working group. The guide reflects relevant literature and research, and the knowledge and experience of forestry staff in the management of the working group in Ontario and elsewhere. The guide covers the range and commercial importance of white pine and red spruce, siting, and wildlife and environmental considerations. Management prescriptions include such silvicultural systems as shelterwood and clear cut systems, harvesting considerations, forest renewal, stand maintenance, conversion and management intensity. Data is also given on the age-class distribution, historical harvest, average roundwood receipts, and biological rotation ages.
