This study quantified the landscape characteristics of eastern white pine and red pine forests in Ontario using a combination of LANDSAT TM imagery and aerial photographs to develop a spatial data base of 275,000 sq km. Analyses on spatial distribution, representativeness, configuration, and fragmentation were conducted in a GIS environment. Results are presented by pine type by both Hills' ecological hierarchy and the administrative hierarchy of the Ontario Ministry of Natural Resources.
In 1991, a spatial forest database over large regions of Ontario was initiated as the basis for research into forest fragmentation and biodiversity using data generated from the digital analysis of LANDSAT thematic mapper satellite data integrated into a geographic information system (GIS). The project was later extended into the the eastern segment of the Boreal forest system. This report describes preparation of the spatial forest data base over the eastern Boreal Forest Region that extends from the northern boundary of the Great Lakes-St. Lawrence Forest Region and the southern margin of the James Bay Lowland, between the Ontario-Quebec border and a point west of Michipicoten on Lake Superior. The report describes the methodology used to produce the data base and results, including mapping of water, dense and sparse conifer forest, mixed forest, dense and sparse deciduous forest, poorly vegetated areas, recent cutovers of less than 10 years, old cutovers and burns, recent burns of less than 10 years, wetlands, bedrock outcrops, agriculture, built-up areas, and mine tailings.
This annotated bibliography contains citations to all publications written, co-authored, or commissioned by Ontario Forest Research Institute staff between 1990 and 1995. Over this period, over 400 publications were produced, including 78 journal articles, 60 reports, 13 program annual reports, six guides or handbooks, 31 technical notes, 80 newsletters or newsletter articles, 34 papers in conference or workshop proceedings, and 115 abstracts of proceedings. Includes author index.
The Old Growth Forest Fragmentation and Biodiversity Program is designed to address knowledge gaps, improve communication among partners, and address the needs of the committees involved in the policy development process. This report is part of the old growth program that deals with the problem of the fauna associated with old growth pine. To provide direction to the planned study of fauna of red and white pine old-growth forests in Ontario, the opinions of 35 selected members of the scientific community who had experience in forest ecosystem ecology and expertise in a particular faunal group were surveyed via two questionnaires. Recommendations are included.
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.
