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
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
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
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.

Book Description
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.

Book Description
This report summarizes the most recent literature describing the impacts of current climate and the potential effects of anticipated climate change on the environment and on those social and economic sectors in Ontario most likely to undergo significant changes. After the introduction, chapter 2 describes the physical and socio-economic resources of Ontario. Chapter 3 details current climatic conditions in the province, including variability and recent trends. Chapter 4 reviews the impacts of the current climate on the following sectors: water resources, human and ecosystem health, the built environment, and industries such as energy, transportation, tourism and recreation, agriculture, forestry, construction, and finance. This chapter also examines the relationship between climate and regional air issues. Chapter 5 surveys future climate scenarios and assesses the impacts and opportunities arising from these scenarios for the same sectors addressed in chapter 4. Chapter 6 reviews the research and application of adaptive measures in five areas: water resources, human and ecosystem health, the built environment, industry, and regional air issues. The chapter also reviews Ontario's adaptation capacity with respect to these sectors. The final chapter summarizes knowledge gaps and research priorities for Ontario in the areas of climate variability and change, impacts and adaptation.
