Available in PDF, EPUB and Kindle. Book excerpt: This report has been prepared in response to an identified need to provide guidance to forest managers seeking to report on a carbon budget at the scale of the forest management unit. Key concepts, tasks, and methods related to carbon budgeting are first reviewed, and a few points gleaned from research carried out in Canadian model forests are summarized. Carbon budgeting is then explained with reference to three distinct tasks: obtaining a baseline measurement of the amount of carbon in a particular forest at a given time; measuring the change to that stock over time; and evaluating the likely impact of various management activities on future changes to the carbon budget. Information needed in order to apply these steps is given, with a focus on how to use existing inventories to record carbon stocks & fluxes. The report concludes with a listing of some activities that could help to store carbon in forests.

This book was released on 2005 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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 book was released on 2010 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational-scale Carbon Budget Model of the Canadian Forest Sector 3 (CBM-CFS3) is an inventory-based carbon model that consists of a linked set of submodels for live biomass, dead organic matter, forest management, land-use change, and disturbance. The model is an integral part of Canada's National Forest Monitoring, Accounting and Reporting system. This study focuses on the verification of components of the dead organic matter submodel of the CBM-CFS3. The submodel controls the dynamics of all dead organic matter pools, the release of decayed material to the atmosphere, and the transfer of carbon to the humified organic material (the model's slow carbon pool). The study is divided into five sections, detailing the background of the experiment, its design, the parameters, the summary of results, and tables.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: The Carbon Budget Model of the Canadian Forest Sector is a national-scale model of forest sector carbon pools and fluxes. This model has been applied to conduct a retrospective analysis of the carbon budget of British Columbia forests for 1920-1989. This report details the assumptions behind the model and the data sources for historic disturbances such as wildfire, forest insects, and different types of harvesting. It then presents model results for biomass and soil carbon pools, carbon fluxes, changes in forest age-class structure, and the model's sensitivity to a change in the assumption that biomass can decline in the overmature growth phase. The appendix includes a summary of a workshop examining the retrospective analysis.

This book was released on 2000 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the use of a well-established carbon budget model for the Canadian forest sector to investigate the carbon budget of Ontario's forest ecosystems. It first reviews the model and its components, then presents results of model runs using input data mainly based on a 1985 forest biomass inventory database. Model simulations begin in 1989 with simulated initial ecosystem conditions that are the endpoint of a 70-year retrospective model run for the period 1920-1989. Results are discussed with regard to forest age structure, forest carbon distribution & stocks, and ecosystem carbon fluxes. The final section includes discussion of the contribution of Ontario forest ecosystems to Canada's carbon budgets and recommendations for further research.
Download or read book Socioeconomic Impacts and Adaptive Responses to Climate Change written by Grant Hauer and published by Canadian Forest Service, Northern Forestry Centre. This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of social science analysis of climate change is to assist policy makers in understanding the expected flows of benefits and costs of policy options over time and to improve our understanding of the human dimensions of the climate change issue. This report deals with socioeconomic criteria for assessment and with the development of methods and approaches for obtaining a better understanding of the socioeconomic impacts and adaptive responses to climate change in Canada's forest sector. Policy makers responding to the climate change issue must deal with many complex issues and unique circumstances. These issues and circumstances also have a bearing on methodologies for undertaking analysis of the future impacts of climate change. Climate change and the effects of climate change on human society spans multiple scales, which leads to the need to consider feedback's and interactions between environmental and human systems, between political systems and between different parts or segments of economies. The implications are that dynamic general or partial equilibrium models integrated with ecosystem response models will be required in order to understand the implications of climate change for land use change, future ecosystem distributions and the supply of timber from Canada's forests. In addition to affecting future timber supply and future commercial forest areas, climate change will influence the benefits Canadians receive from non-market benefits such as outdoor recreation. Currently there is limited analysis of the effects of climate change on non-market values and this area requires more work. Another factor influencing climate change analysis is that the issue spans unusually long time frames for policy analysis and economic analysis. This raises questions about suitable discount rates and accounting for social welfare of future generations. Finally, there is significant uncertainty in long term predictions of climate change and in how the integrated human/biological system will respond over time. Decision analysis, safe minimum standards, precautionary principles and maximin criterion provide some way to incorporate uncertainty into decision making. In terms of integrated assessment models, systematic consideration for the diversity of opinions and results from scientific studies regarding future climate and ecosystems shifts is required.
Download or read book The Importance of Forest Sector Adaptation to Climate Change written by T. C. Lemprière and published by . This book was released on 2008 with total page 80 pages. 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.

Technical Advisory Committee and published by . This book was released on 2001 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of scale of data must be addressed if forest managers are to minimize errors when data collected at one organizational level are used to estimate parameters at another. This paper discusses the following issues concerning scale: the issues of scale regarding the collection & aggregation of data at the subnational & national levels; the effect of scale on the interpretation of data; and the implications of the periodicity of nationally collected data on subnational application of criteria & indicators of sustainable forest management. The paper also provides examples from several countries on mechanisms for the development, identification, and implementation of subnational indicators of sustainable forest management that can be linked to national indicators.

Book excerpt: This report presents the work of the Forest Sector Table, established to analyze & evaluate forest sector greenhouse gas (GHG) reduction options to aid in implementing the Kyoto Protocol. The Table evaluated the potential for the forest sector to help reduce GHG emissions and to offset such emissions through carbon sequestration. Options presented in the report are analyzed in terms of their costs & mitigation potential as well as other considerations including implications for competitiveness, environmental & health impacts, and employment. After an introduction on the Table's analytical approach & linkages with other Tables, section 2 presents an overview of the Canadian forest sector and concerns regarding the Kyoto Protocol & international issues. Section 3 assesses forest industry energy options for improving energy efficiency, switching fuels, utilizing emerging technologies, and developing wood ethanol production. Section 4 examines carbon sequestration options currently in the Protocol (afforestation, reforestation, deforestation) and not in the Protocol (measures related to forest management & carbon stored in forest products). The final section summarizes the measures evaluated and makes recommendations for action & for policy measures.
Download or read book Carbon Management in British Columbia s Forests written by Mike Greig and published by . This book was released on 2009 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most ecosystems, the majority of the carbon is stored below ground as roots and decaying biomass or as organic carbon in the soil. [...] In both the forest and non-forest environment, when we measure the total carbon content we are measuring what is referred to as the "carbon stock." The carbon stored in forests is sequestered from the atmosphere through photosynthesis (the conversion of atmospheric CO2 into plant material using energy from the sun, releasing oxygen in the process) (Figure 1). [...] In some cases, acts of fire suppression and protection against insects lead to reductions in the affected areas and help maintain the level of carbon stored; however, uncertainty surrounds our ability to reduce the impacts of fire and insects on carbon over the long term or over large landscapes (see Section 2.2.1 below). [...] The Canadian Forest Service recently pointed out the important roles of forests and sustainable forest management in the global climate system: "forests play two important roles in the global climate system: first, they remove carbon from the atmosphere and store it in trees, litter and soil carbon, and second, they provide timber, fibre and energy to meet human demands. [...] In the February 2008 Speech from the Throne, the Premier outlined the following new or existing measures to reduce the province's carbon footprint: the zero net deforestation goal, the Trees for Tomorrow program, the restocking of all forest land, the Forests for Tomorrow program,2 the Bioenergy Strategy, the Pacific Carbon Trust, and new investments in carbon offset projects that benefit First Na.
