This book was released on 2005 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large body of research has documented evidence of climate change impact already occurring on different systems on earth, future impacts can be expected. Accordingly, research is urgently needed to analyze the potential impacts of climate change on forest ecosystems in order to contribute to better landscape planning and management. This thesis investigates how climate change affects landscape change, and how to use this understanding in the analysis of land-use and landscape planning and management to adapt to climate change impacts. In particular, this study examines how climate change may impact a managed forest in terms of timber availability, and the regional community that relies on it for its survival. I hypothesized that the Boreal forest in north western Ontario will change in the short term (i.e. 60 years) in species composition and will produce less available timber as a result of human-induced climate change as modeled by different General Circulation Models plus harvesting, compared to a baseline climate. The study objectives were (a) to evaluate the degree of change in land cover (species composition) under forest harvesting and various climate change scenarios; (b) to analyze timber availability under different climate change scenarios, and harvesting; (c) to describe possible scenarios of land cover change as a result of climate change impact and harvesting to assist in policy-making related to land-use and landscape planning; and (d) to identify possible sources of both land-use conflicts and synergies as a result of changes in landscape composition caused by climate change. The study area was the Dog-River Matawin forest in north western Ontario (̃8 x 104 ha). It is currently under harvesting. I used the Boreal Forest Landscape Dynamic Simulator (BFOLDS) fire model to simulate landscape change under different climate change scenarios (CCSRNIES A21, CGCM2 A22), which were then compared to simulations under a baseline climate scenario (1961-1990). I also developed an algorithm for the geographic information systems Arc View©, that selected useful stands, and simulated harvesting and regeneration rules after logging, processes not currently included in BFOLDS. The studied period covered 60 years to analyze impacts in the medium term in the landscape change. Results obtained were the following. (1) There will be a shortage in timber availability under all scenarios including the baseline. The impacts of climate change will cause a deficit in timber availability much earlier under a warmer scenario with respect to the baseline. The combined impact of climate change and harvesting could diminish timber availability up to 35% compared to the baseline by year 2040 under the CCSRNIES A21 scenario mainly due to an increase in fires. Deficits will occur 10 years before in the same scenario compared to the baseline (by year 2035). (2) In both scenarios and the baseline, there will be a younger forest. In 60 years, there will not be mature forest to support ecological, social and economic processes, as the forest will only have young stands. (3) Results obtained indicated that species composition will not change importantly among the scenarios of climate change and the baseline every decade, but there will be a change in dominance along the 60 years of the simulation under each scenario including the baseline. Softwood increased in dominance and hardwood decreased in all scenarios. The period length used in the simulation of 60 years appeared to be too short to reveal conspicuous changes in species composition. Increases observed in softwood over hardwood related to the increase in fires which promoted the establishment of species such as jack pine as well as the application of regeneration rules after logging. This finding did not agree with the hypothesis. Results of timber availability were consistent with what I expected. Warmest climate change scenarios (CCSRNIES A21) impacted both the amount of timber available (less availability every ten years) from the beginning of the simulation and the time when deficits occurred. There are important economic, social and environmental implications of the results of this study, namely a future forest that would be young and would supply much less timber. For the forestry industry, production goals would be hindered in the medium term, falling short of industry demands. For a society that depends heavily upon the forest to survive, declining production can imply unemployment, thus affecting the welfare of the community. For the environment, such a young, fragmented forest could be unable to sustain important key species and ecological processes, leading to a loss of biodiversity, Land-use and landscape planning should be used to regulate how the land is used to minimize climate change impact. They should be further used as adaptation tools, to help in ameliorate those climate change impacts that do occur.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Interactions between forests, climatic change and the Earths carbon cycle are complex and represent a challenge for forest managers they are integral to the sustainable management of forests. In this volume, a number of papers are presented that describe some of the complex relationships between climate, the global carbon cycle and forests. Research has demonstrated that these are closely connected, such that changes in one have an influence not only on the other two, but also on their linkages. Climatic change represents a considerable threat to forest management in the current static paradigm. However, carbon sequestration issues offer opportunities for new techniques and strategies, and those able to adapt their management to this changing situation are likely to benefit. Such changes are already underway in countries such as Australia and Costa Rica, but it will probably take much longer for the forestry sector in the Pacific Northwest region of North America (encompassing Oregon, Washington, Montana, Idaho, British Columbia and Alaska) to change their current practices.

Available in PDF, EPUB and Kindle. Book excerpt: As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: "The climate in Canada's north has changed over the past 70 years. Indeed, mean annual temperature in the Northwest Territories has increased by 2°C to 4°C since record keeping began in 1950. Annual precipitation amounts and patterns have also changed during this period. These and other changes have already noticeably affected the appearance and function of northern forested ecosystems and will continue to do so into the future. As such, the Government of Northwest Territories and the Canadian Forest Service have collaborated to produce this baseline report summarizing the current ecological conditions of forested ecosystems in the Northwest Territories and identifying gaps in our understanding of northern forests and ecosystem processes"--Abstract, page iii.

Book excerpt: Nearing the end of a lifetime in the boreal forest, a retired forester writes a passionate plea for rational, science-based forest management. The boreal forest is constantly changing, often dramatically. We like to picture it as a stable, balanced system. Really, it is anything but stable. The boreal forest is dynamic. For over sixty years, forester Malcolm F. Squires has seen mature forests within protected areas devastated by insects, moose, wind, and wildfire. While the forests often return from this destruction, they are never quite the same. A naturally balanced boreal forest is a human notion that does not match the reality of nature. If we don’t soon recognize and accept that reality and stop making irrational demands that a forest be “protected” from change or human management, we may be dooming them to disaster.
