Forest Ecosystems, Forest Management and the Global Carbon Cycle by Michael J. Apps,David T. Price Pdf
Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.
Managing Forest Carbon in a Changing Climate by Mark S. Ashton,Mary L. Tyrrell,Deborah Spalding,Bradford Gentry Pdf
The aim of this book is to provide an accessible overview for advanced students, resource professionals such as land managers, and policy makers to acquaint themselves with the established science, management practices and policies that facilitate sequestration and allow for the storage of carbon in forests. The book has value to the reader to better understand: a) carbon science and management of forests and wood products; b) the underlying social mechanisms of deforestation; and c) the policy options in order to formulate a cohesive strategy for implementing forest carbon projects and ultimately reducing emissions from forest land use.
Carbon Dioxide Mitigation in Forestry and Wood Industry by Gundolf H. Kohlmaier,Michael Weber,Richard A. Houghton Pdf
The lntergovernmental Panel on Climate Change (IPCC) has recently summarized the state ofthe art in research on climate change (Climate Change 1995). The most up to date research findings have been divided into three volumes: • the Science ofClimate Change (working group I), • the Impacts, Adaption and Mitigation of Climate Change (working group II), and • the Economic and Social Dimensions ofClimate Change (working group III) There is a general consensus that a serious change in climate can only be avoided if the future emissions of greenhouse gases are reduced considerably from the business as usual projection and if at the same time the natural sinks for greenhouse gases, in particular that of CO , are maintained at the present level or 2 preferrably increased. Forests, forestry and forestry industry are important parts of the global carbon cycle and therefore they are also part of the mitigation potentials in at least a threefold way: 1. During the time period between 1980 and 1989 there was a net emission of CO from changes in tropical land use (mostly tropical deforestation) of 2 1. 6 +/- 1 GtC/a, but at the same time it was estimated that the forests in the northem hemisphere have taken up 0. 5 +/- 0. 5 GtC/a and additionally other terrestrial sinks (including tropical forests where no clearing took place) have been a carbon sink ofthe order of l. 3 +/- l.

The Carbon Balance of Forest Biomes by Howard Griffith,Paul Jarvis Pdf
The Carbon Balance of Forest Biomes provides an informed synthesis on the current status of forests and their future potential for carbon sequestration. This volume is timely, since convincing models which scale from local to regional carbon fluxes are needed to support these international agreements, whilst criticisms have been levelled at existing empirical approaches. One key question is to determine how well eddy-flux measurements at the stand-level represent regional-scale processes. This may be related to specific management practices (age, plantation, fertilisation) or simple bias in choosing representative sites (ease of access, roughness, proximity to physical barriers). The ecology and regeneration state of temperate, tropical and boreal forests under current climatic conditions are discussed, together with partitioning of photosynthetic and respiratory fluxes from soils and vegetation. The volume considers how to integrate contrasting methodologies, and the latest approaches for scaling from stand to the planetary boundary layer.
Carbon Budget Accounting at the Forest Management Unit Level by Martin Von Mirbach,Canadian Model Forest Network Pdf
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.
Boreal Forests in the Face of Climate Change by Miguel Montoro Girona,Hubert Morin,Sylvie Gauthier,Yves Bergeron Pdf
This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth’s forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a novel framework is required to adapt forest strategies and practices to climate change. This collaborative effort draws upon 148 authors in summarizing the sustainable management of these forests and detailing the most recent experimental and observational results collected from across the boreal biome. It presents the state of sustainable management in boreal forests and highlights the critical importance of this biome in a context of global change because of these forests' key role in a range of natural processes, including carbon sequestration, nutrient cycling, and the maintaining of biodiversity. This book is an essential read for academics, students, and practitioners involved in boreal forest management. It outlines the challenges facing sustainable boreal forest management within the context of climate change and serves as a basis for establishing new research avenues, identifying future research trends, and developing climate-adapted forest management plans.
Managing Boreal Forests in the Context of Climate Change by Seppo Kellomaki Pdf
In many places in the world, forests dominate landscapes and provide various products. Future climate change could profoundly alter the productivity of forest ecosystems and species composition. Until now, climate impact research has primarily focused on the likely impacts of rise in temperature, increased atmospheric CO2 concentration, and varying precipitation on unmanaged forests. The issue that now needs to be addressed is how to sustainably manage climate change for timber production and biomass. Though climate change is a global issue, impacts on forests depend on local environmental conditions and management methods, so this book will look at the issue under varying local contexts.

The Carbon Budget of British Columbia's Forests, 1920-1989 by Werner Alexander Kurz,British Columbia. Ministry of Forests,Canada-British Columbia Partnership Agreement on Forest Resource Development: FRDA II.,Canadian Forest Service Pdf
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.
