Boreal Forest Succession in Ontario by M. Drescher Pdf

Forest succession can be viewed, from a tree-centric point of view, as the temporal pattern of changes in tree species composition that occur following a disturbance that destroyed the existing forest cover, and includes the initial re-establishment of the forest cover. Fire is one such natural disturbance in boreal forests. The broad goal of the work reported here was to explore the body of boreal forest succession knowledge, to elucidate its strengths, weaknesses, and gaps, and to quantify its levels of uncertainty.--Document.

Identifying Uncertainty in Practitioner Knowledge of Boreal Forest Succession in Ontario Through a Workshop Approach by M. Drescher Pdf

Expert knowledge of boreal forest succession is used widely in forest management in boreal Ontario, but the level of uncertainty of this mainly implicit knowledge is unknown. Therefore, in this study expert knowledge of boreal forest succession was elicited, it's uncertainty quantified, and the sources of this uncertainty investigated. This report consists of four main parts. The introduction presents examples of the use of forest succession knowledge in forest management in boreal Ontario. The methods section provides background information about the concept of knowledge uncertainty and possible assessment methods and describes the characteristics of experts. The results section details the quantification of the various components of uncertainty and describes the distribution of uncertainty. The conclusions section presents the strengths and weaknesses of this study and discusses the implications of the study results for forest policy and management in Ontario.--Includes text from document.

Modelling Boreal Forest Succession at Broad Scales by Dennis Yemshanov,Ajith Perera,Ontario Forest Research Institute Pdf

This bibliography was produced to assist foresters and scientists interested in modelling boreal forest succession at broad scales. It contains more than 600 citations describing existing knowledge on succession in North American boreal forests, and the current state-of-knowledge in modelling succession, with particular emphasis on broad scales. References on succession in boreal forests are grouped by geographic and taxonomic categories. This bibliography also provides information on theories and concepts of succession modelling, issues of scale in modelling succession, the spatial process of propagule dispersal, and the probalistic modelling of forest succession. An author index is provided to help users located citations of interest.

Studying Successional Pathways in Forest Communities by Julie A. Elliot,David M. Morris,Ontario. Ministry of Natural Resources,Jamie L. Kantor,Ontario Forest Research Institute Pdf

Annotated bibliography whose purpose is to aid in the development of research initiatives studying forest succession in Ontario by providing a central source of relevant material. Although the focus was on northern forest ecosystems, articles that had application to studying succession in these ecosystems were also included. The bibliography is divided into succession theory, natural succession, role of fire, impacts of harvesting, relationship to nutrient cycling, and modelling. Articles are cross-referenced by subject area. Also included are a list of scientific and common names for plant species, and a list of books, conferences and proceedings associated with forest succession.

Multiple Scale Research Studies on Boreal Forest Fires Regimes to Inform Ontario's Policies for Emulating Natural Forest Disturbances by Ajith H. Perera Pdf

This prospectus presents a broad framework for a series of research studies to investigate Ontario boreal forest fire regime at multiple scales. The broad research goal is to reduce uncertainties in knowledge about boreal forest fire regimes related to policy directions in Ministry of Natural Resources' Forest management guide for natural disturbance pattern emulation. The research studies are grouped into three categories: reviews and syntheses of published literature; determining the characteristics of the broad-scale fire regime in boreal Ontario; and spatial mapping and monitoring.

Modelling Landscape-level Vegetation Dynamics in the Boreal Forests of Northwestern Ontario by Norman Charles Kenkel,Peter Wolfgang Christopher Uhlig,Paul R. Watson,Ontario Forest Research Institute Pdf

Describes a study undertaken to develop a synoptic model of forest succession (vegetation dynamics) in the north-western Ontario boreal region. Successional trends were inferred using two complementary approaches: analysis of class size distributions of trees and species vital attributes, and enumeration of stands at different post-fire ages. A sample of 1,389 plots enumerated within a study area of about 184,000 square kilometres was used. Cover values and detailed information on edaphic and landform variables were collected from each plot. Model development included classification into one of 12 vegetation stand types, summarizing of successional trajectories for each stand type, and synthesis of the trajectories to create a synoptic forest succession model that recognizes two self-perpetuating forest canopy types.

Forest Fire Size Distribution in North American Boreal Forests by Wenbin Cui,Ajith H. Perera,Ontario Forest Research Institute Pdf

The goal of this report is to investigate and summarize the current knowledge about fire size distribution (FSD), with special reference to how resource professionals and researchers use FSD, and where the gaps in FSD knowledge are. The focus of this investigation, given Ontario's vantage point, was the North American boreal forest. First, the report examines factors necessary to understand FSD; second, it summarizes what is reported on FSD in scientific literature; third, it reviews the past research on FSD, focusing on methodologies and approaches; finally, it offers a summary of the state of knowledge on FSD, including knowledge gap.--Document.

Early Successional Processes of Eastern White Pine and Red Pine in the Great Lakes-St. Lawrence Forest by Helen Maureen Kershaw,Ontario Forest Research Institute,Ontario. Ministry of Natural Resources Pdf

This report reviews the literature relating to red pine and eastern white pine succession in the Great Lakes-St. Lawrence Forest from establishment to age 50. Research areas included red and white pine autecology, early red and white pine establishment and survival, post-disturbance natural successional patterns, and the effect of past and current management practices on early red and white pine survival and establishment. Professional foresters, working in Ontario, were consulted to determine current forest management practices.
