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.

This study represents an analysis of regeneration processes for eastern white pine (Pinus strohus L.). The objective is to develop an integrated approach to evaluate the influence of factors that, alone and in combination, determine regeneration outcomes. This study is composed of three sections. The first chapter is a literature review of white pine regeneration dynamics. The purpose is to present a process for understanding the regeneration process of a single species and present a conceptual approach to integrated evaluation of influential variables. Six interrelated ecological factors (seed tree density, competition, disturbance, seedbed conditions, soils, and damage agents) were identified and their impact on the regeneration process is evaluated. A conceptual model of the integration approach and two examples of how this approach can be utilized in assessing regeneration operations are presented.
