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.

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.

"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.

"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.

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.

'Ironically, the threat of global warming damage provides us with one of the most powerful arguments for avoiding the worst excesses of another global problem - deforestation. Dore and Guevara have assembled a very impressive set of essays that show just how important our forests are as carbon stores and sinks. Let us hope someone is listening.' - David Pearce, University College London, UK 'Global carbon emissions from the burning of fossil fuels seem destined to rise with adverse consequences for global warming and for sea-level rise. This book explores how and to what extent conservation and re-growth of tropical forests can ameliorate this problem, as well as placing economic values on such strategies. Individual contributions draw on the Americas experience to examine biophysical aspects of forestry relevant to sustainability, evaluate the economics of forest retention giving particular attention to non-market values, and assess forest policies in terms of their impacts on environmental conservation. . . . a readable holistic book accessible to a wide audience of economists, non-economists and policymakers, highlighting a major problem which refuses to go away.' - Clem Tisdell, University of Queensland, Australia The UN Framework Convention on Climate Change recognises that, in the formulation of a global strategy for reducing global emissions of carbon (the main factor in global warming) forests could play an important role. This book highlights that role and demonstrates how the forests of the world may be harvested judiciously and sustainably. The authors argue that the forests are more than just a source of timber and wood; they discuss the role that forests play in reducing global warming, in preventing soil erosion and in helping to minimise the loss of biodiversity. Drawing on the expertise of contributors associated with the analysis of forests, this book is an in depth and fascinating discussion as well as a policy guide for the sustainable management of forests.
