This book was released on 2008 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting the effect of climate change on insect populations can be used to estimate the costs and benefits of protecting forests from potential damage. In this report, the authors present an analysis of potential changes in the distribution of spruce budworm (Choristoneura fumiferana Clem.) defoliation under climate change in Ontario. They use an empirical model that relates defoliation to historical bioclimatic variables, and then apply climate change data to this model to predict potential changes in the distribution of defoliation.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: On- strategies organized according to the need to understand climate site land use planning and management techniques must be change, mitigate the impacts of rapid climate change, and help designed to protect the ecological and social pieces, patterns, Ontarians adapt to climate change: and processes. [...] Given the uncertainty in the amount of emissions and associated effects, natural resource management agencies around the world are using a number of climate models and scenarios of human behaviour to depict a range of potential climatic conditions and impacts that may appear in the next 100 years. [...] It is notable that the countries attending the 2005 climate change conference in Montreal to review and discuss future programs under the auspices of the United Nations Framework Convention on Climate Change and the Kyoto Protocol agreed that the development of adaptation tools and techniques should receive significant attention during the next 5 years. [...] Species Distribution and Abundance in Response to Climate Change The distribution and abundance of a species across its geographic range is related to both biotic (e.g., food, competition, and disease) and abiotic (e.g., climate and substrate) factors. [...] There are several ways to examine the effects of climate on terrestrial fauna, and to determine how climate change may affect species and their habitat in the future.

Download or read book Climate Change and United States Forests written by David L. Peterson and published by Springer. This book was released on 2014-01-10 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a scientific assessment of the effects of climatic variability and change on forest resources in the United States. Derived from a report that provides technical input to the 2013 U.S. Global Change Research Program National Climate Assessment, the book serves as a framework for managing U.S. forest resources in the context of climate change. The authors focus on topics having the greatest potential to alter the structure and function of forest ecosystems, and therefore ecosystem services, by the end of the 21st century. Part I provides an environmental context for assessing the effects of climate change on forest resources, summarizing changes in environmental stressors, followed by state-of-science projections for future climatic conditions relevant to forest ecosystems. Part II offers a wide-ranging assessment of vulnerability of forest ecosystems and ecosystem services to climate change. The authors anticipate that altered disturbance regimes and stressors will have the biggest effects on forest ecosystems, causing long-term changes in forest conditions. Part III outlines responses to climate change, summarizing current status and trends in forest carbon, effects of carbon management, and carbon mitigation strategies. Adaptation strategies and a proposed framework for risk assessment, including case studies, provide a structured approach for projecting and responding to future changes in resource conditions and ecosystem services. Part IV describes how sustainable forest management, which guides activities on most public and private lands in the United States, can provide an overarching structure for mitigating and adapting to climate change.

Download or read book Patterns and Processes Affecting Northward Migration of Tree Species in a Changing Climate written by Laura Boisvert-Marsh and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Northern limits of species distributions are at the 'leading edge' of studies on biological response to climate change, and therefore examining changes in species distributions is a crucial step in quantifying species' potential to track climate through poleward migration. Tracking distributional changes over large geographic areas remains a challenge, however, and the abiotic and biotic contexts under which these changes are occurring are unclear. The overall objective of this thesis is to understand the patterns and processes of range shifts in relation to rapid environmental change, focusing on forest tree species of Eastern North America to inform sustainable forest management. In the first study, I aimed to identify migration pathways from northern temperate to boreal forests for species showing range expansion. In the second study, I focused on climate change and natural and anthropogenic disturbances to assess their relative influence on observed patterns of species range shifts. In the third study, I developed a modelling framework to evaluate the potential for range shift for 10 tree species in response to climate change by integrating information on life history and dispersal ability to improve projections. These three studies improve our knowledge about tree species responses to climate change across time and space, showing how local biotic and abiotic factors translate into responses at broader scales and which processes underlie the observed patterns. Species are showing evidence of migration in response to warming especially toward their northern range limit, with some taking advantage of migration pathways that involve disturbances disrupting priority effects and associated species facilitating establishment in challenging environmental conditions. Species that can benefit the most from novel biotic interactions and disturbances in the boreal forest, and whose dispersal and establishment is relatively effective are likely to expand their range without assistance while others could require some intervention. Developing management strategies that consider the potential for species to track their suitable climate is an important step toward sustainable forest management, and this thesis can help incorporate ecological knowledge into the planning process"--

This book was released on 2012 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The vulnerability of the forest vegetation of Ontario's northern Clay Belt region to climate change was assessed using forest tree species composition and forest productivity as indicators. Changes in species composition were examined using the modelled bioclimatic niche of 15 tree species under current and future climate projected for three periods using four general circulation models and two emissions scenarios. Using climate projections from an ensemble model for these same scenarios and periods as inputs to climate-based site index and genecological models, changes in height growth were examined for several major tree species of the region as a measure of effects of climate on forest productivity. Major northward geographic shifts in species bioclimatic niche were projected, resulting in suitable climatic habitat decreasing for boreal forest species of the region, and becoming more favourable for species currently associated with more southern, i.e., Great Lakes-St. Lawrence, areas."--Document.
