Book Description
This report updates a review of literature about the effects of global climate change on forest plants and communities published in 1998. The focus is on changes in Ontario predicted for forest fires, insect outbreaks, disease, forest growth, species composition, harvest rates, wood supply, genetics and regeneration, and carbon-based forest management.--Includes text from document.

Book Description
Reviews literature concerning the effects of global climate change on forest plants and communities, and provides opinions on the potential impacts that climate change may have on Ontario forests. Sections of the review discuss the following: the climate of Ontario in the 21st century as predicted by climate models; forest hydrology in relation to climate change; insects and climate change; impacts on fungi in the forest ecosystem; impacts on forest fires and their management; plant physiological responses; genetic implications of climate change; forest vegetation dynamics; the use of models in global climate change studies; and forest management responses to climate change.

Book Description
Assisted migration of tree species populations, or seed sources, is one of few adaptive strategies available to mitigate the projected effects of climate change on the structure, productivity, and distribution of forest ecosystems. In this report, the authors present the goals and objectives of a study intiated in 2008 to assess the potential of assisted migration as an adaptation strategy to manage for climate change in Ontario. In support of this study, they conducted a literature search on assisted migration and genetic variation in climatic response of forest tree species, through which were identified several hundred related scientific and technical publications. Citations and keywords for publications of greatest significance to using assisted migration as a climate change adaptation strategy are presented in the accompanying bibliography.--Document.

Book Description
"This report examines how forest management can affect the carbon (C) balance of Ontario's forests. Ten forest management activities organized in four themes were examined: stand establishment (site preparation, planting, and vegetation management), growth enhancement (thinning, fertilization, and genetic improvement), forest protection (from forest fires, and insect and disease infestations), and harvesting (controlling the area occupied by roads, skid trails and landings, and reducing the area disturbed by harvesting)."--Document.

Book Description
"Forest carbon and how it changes over time provides an indicator of the sustainability of forest management. It is also a sign of sequestration or emission of carbon dioxide between forests and the atmosphere that can affect the mitigation of atmospheric greenhouse gas accumulation and global climate change. To address the need for information on Ontario's forest carbon budget, a large-scale forest carbon modelling project was initiated. The background and objectives of this project are described in this report. Three complementary approaches are being used to estimate large-scale forest carbon storage in Ontario's forests: (1) the Carbon Budget Model of the Canadian Forest Sector (CBMCFS), (2) a modified version of FORCARB, which is the model developed by the United States Department of Agriculture (USDA) Forest Service to estimate carbon in U.S. forests, and (3) direct estimation of forest biomass carbon using Ontario's growth and yield and forest resources inventory data (CAM, the Carbon Allometry Method)."--Docment.

Book Description
This report summarizes current knowledge about recent changes in the climate of Canadas forests and projects further changes over this century based on scenarios of future global greenhouse gas emissions developed by the Intergovernmental Panel on Climate Change. Even with sustained reductions in global emissions the future climate is predicted to be quite different, meaning that adaptation will be essential. Impacts on the forest are already occurring and will be substantial in the future. The current upward trend in area burned annually is expected to continue. Forests will be prone to widespread stress induced by the changing climate, increasing the likelihood of pest outbreaks in the short to medium term. Recent outbreaks of several pests have exceeded in scope all previous known epidemics of these pests and are associated with the crossing of a climatic threshold. Invasion of the boreal forest by the mountain pine beetle, Dendroctonus ponderosae (Hopkins), appears likely, although the effect of this range expansion would likely be less severe than that observed recently in British Columbia, and outbreaks of the spruce budworm, Choristoneura fumiferana (Clemens), are predicted to be longer and more severe in the future. Future forest growth in response to climate change is expected to be variable, with growth reduction because of drought in parts of Canadas western forests perhaps the most dramatic short- to medium-term outcome, though modestly increased growth in the east is predicted. Such impacts have implications for the cost and characteristics of timber supply, and climate change will also affect forestry operations, recreation opportunities, biodiversity, and carbon storage. Planning based on past approaches will need to be reconsidered. Current objectives for sustainable forest management may not be attainable in the future, although there may be some new opportunities. Climate change may produce public safety risks, significant economic and social dislocation in forest-dependent communities including Aboriginal communities, and impacts on the competitiveness of companies as well as on the actions and policies of all levels of government. These effects can be reduced through early identification and implementation of actions to reduce vulnerabilities or take advantage of new opportunities. The key needs associated with adaptation in the forest sector include awareness building and debate, improved knowledge and information, vulnerability assessments, planning frameworks and tools, and enhanced coordination and cooperation among governments and other forest sector participants. Meeting the challenge of adaptation will require sustained effort for many years.

Book Description
The increased fi re load is expected to increase the cost of fi re management in the province 16% by the year 2040 and 54% by the year 2090 over year 2000 costs, exclusive of infl ation or other factors. [...] In addition to increases in seasonal fi re severity indices, a number of these studies also predict increases in the frequency of occurrence of extreme fi re danger in some areas of the country (e.g., Stocks et al. [...] This study uses lightning- and people-caused fi re occurrence models developed specifi cally for Ontario with GCM projections of future climate and Ontario's level of protection analysis software, LEOPARDS (see McAlpine and Hirsch 1999) to estimate the impacts of climate change on the fi re management organization both in terms of numbers of escaped fi res and with respect to changes in operationa [...] The sites of the GCM grid cell centres and OMNR weather stations used are shown in Figure 1. Fire Weather and Fire Danger To create the fi re climate of a future decade, the monthly anomalies were applied to the daily data from the OMNR fi re weather station archive from the years 1992-2001 (corresponding to the period over which lightning records were available). [...] The Fire Behaviour Prediction (FBP) System (Forestry Canada Fire Danger Group 1992) was used in conjunction with the Initial Spread Index (ISI), the Build-up Index (BUI) (calculated on the detection date of the fi re using the FWI System), and the fuel type associated with the fi re to estimate an initial rate of spread for each fi re.

Book Description
Forest managers can expect the unexpected and they can expect that change will be ongoing and unrelenting. Some general recommendations for beginning to address climate change in Canada's forest sector include enhancing the capacity to undertake integrated assessment of vulnerabilities to climate change at various scales; increasing resources to monitor the impacts of climate change; increasing resources for impacts and adaptation science; reviewing forest policies, forest planning, forest management approaches, and institutions to assess our ability to achieve social objectives under climate change; embedding principles of risk management and adaptive management into forest management; and maintaining or improving the capacity for communicating, networking, and information sharing with the Canadian public and within the forest sector."--Pub. website.
