This book was released on 2012-11 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 (2011-2040, 2041-2070, 2071-2100) using four general circulation models and two emissions scenarios (A2, B1). 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."--publisher.

Available in PDF, EPUB and Kindle. Book excerpt: The authors assessed the vulnerability of furbearers in the Clay Belt to climate change. They identified four processes leading to vulnerability: the introduction of southern competitors and pathogens, increased extinction risk of cold-adapted species, selection for early breeding, and reduced synchrony. Potential indicators of these processes include the distribution and abundance of temperate species, such as the raccoon (Procyon lotor) and the distribution and abundance of cold-adapted species, such as the American marten (Martes americana) and Canada lynx (Lynx canadensis). Other indicators include changes in the seasonal timing of breeding in rodents such as the muskrat (Ondatra zibethicus) and changes to the frequency and amplitude of the lynx-snowshoe hare (Lepus americanus) cycle. Overall, they anticipate that climate change will result in the Clay Belt and its constituent furbearer species becoming more temperate in character.--Document.

Book excerpt: 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.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Projected climate change in the Toronto, Ontario, Canada area could greatly alter tree composition within the urban forest. Investigating biological change as a result of climate change is complicated due to the variability among climate model outputs and non-climatic influences on local vegetation. This study approaches the issues of composition change in tree species in Toronto through three interdependent studies. The first study is a comparison of Global Climate Models (GCMs) available through the Intergovernmental Panel on Climate Change's Fourth and Fifth Assessment Reports, AR4 and AR5 respectively. Using a performance metric based on how well the GCMs simulate climate relative to observation, GCMs GFDL-CM3, IPSL-CM5A-LR and MPI-ESM-LR were determined to provide the best Canada-wide coverage for annual average temperature and precipitation changes. The second study correlates a series of biologically-relevant climatic variables to tree distributions of 134 North American trees east of the 100th meridian. The geographical absence or presence of a species was correlated to concurrent climate data, creating a species' climate envelope. Using climate projections from an ensemble of the GCMs GFDL-CM3, IPSL-CM5A-LR and MPI-ESM-LR for the year 2050, a suite of statistical regression and machine-learning techniques were used to predict a likelihood of suitability of trees in the Toronto area based on the derived climate envelopes. While the dominant beech-maple communities are largely projected to stay intact, future climate suitability is likely to shift away from conifers and northern hardwoods into more southerly deciduous trees. The third study evaluates using projected tree suitability whether an assisted migration through the translocation of tree species would be effective in the Toronto area. Of particular interest is the increasing climate suitability that likely will be beneficial to Ontario's Species at Risk trees. However, the conservation of Ontario's Species at Risk trees cannot be based solely upon projections of climate, a vulnerability assessment conducted in this study indicate that current pest and diseases threats coupled with and the loss of genetic diversity are also cause for concern.
Download or read book Assessing Social Vulnerability to the Impacts of Climate Change on Forest Ecosystems written by Joseph E. Reber and published by . This book was released on 2015 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is expected to alter the composition and distribution of earth's forests. The impacts of these ecological changes will have many social consequences. The individuals and households that will be most affected will likely be those that derive value from forest resources. This thesis proposes a methodology for identifying human populations that may be differentially impacted by forest related climate changes with the use of a social vulnerability framework. Dynamic vegetation change models were used to quantify exposure to climate change related forest changes. Sensitivity and adaptive capacity were calculated using an indicator-based approach. The social (sensitivity and adaptive capacity) and biophysical (exposure) systems were related with a measure of economic forest dependence. The components were combined to produce a measure of vulnerability to forest related climate changes. The results of this assessment are useful for informing management decisions and the proposed methodology allows for the assessment of spatially indirect hazards.

Book excerpt: "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 excerpt: This report is the third in the series. Through a review of literature this part of the FVA project was established to identify the potential socio-economic impacts of climate change and develop a framework for thinking about coordinated responses to socially and economically adverse outcomes. This report is based predominantly on a literature review of relevant economic, social and policy studies. In addition some original work was carried out on the development of a model of plantation decision-making under climate change and a small-scale survey of respondents in two towns in timber growing regions with a good mix of forest types (Bombala in the Eden/Gippsland region; and Scottsdale in north-eastern Tasmania) to determine their response to climate change.
