Book Description
This guide provides silvicultural and ecological information for the management of black spruce, jack pine, and aspen within the context of sustainable forest management in Ontario. Section I introduces and explains the ecological and management interpretations of Section II, the terms and graphical conventions used, how the interpretations were derived, the limitations to their application, and data sources. This section also includes a comparative cross-reference of selected central ecosites and northeast forest ecosystem classification site types. Section II delivers a suite of ecological and silvicultural information within the framework of general standard forest ecosystem classification site types for north-east Ontario.

Book Description
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.

Book Description
Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Book Description
Begins with an introduction on the boreal mixedwood forest in Ontario and a literature review of the habitat, reproduction, and growth of white spruce and black spruce. This is followed by a review of artificial regeneration of spruce after harvesting and an outline of spruce management considerations. Concludes with a report on a case study from the Seine River Demonstration Forest in north-west Ontario. The study was conducted to demonstrate the interaction of site productivity and hardwood competition in the establishment of white and black spruce on a mixedwood site.

Book Description
Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.

Book Description
Guide to assist in the recognition of vegetation and soil features of forest ecosystems in north-western Ontario using a classification system that enables the allocation of any forest ecosystem to one of 40 vegetation types and one of 22 soil types. Provides an orientation to the vegetation classification; describes the vegetation types and their determination, including a key and factsheets for classifying stands to vegetation types; provides keys and factsheets for classifying soil types; and gives a brief overview of the relationships among vegetation and soil types in north-western Ontario as well as background information on potential applications of the classification. Also contains aids for describing or recognizing important soil features and many of the plant species used in the allocation keys and factsheets.
