Book Description
This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Book Description
A full description of computer-based methods of analysis used to define and solve ecological problems. Multivariate techniques permit summary of complex sets of data and allow investigation of many problems which cannot be tackled experimentally because of practical restraints.
Managing Forest Ecosystems: The Challenge of Climate Change
Author: Felipe BravoPublisher: Springer Science & Business Media
ISBN: 1402083432
Category : Science
Languages : en
Pages : 334
Book Description
Climate changes, particularly warming trends, have been recorded around the globe. For many countries, these changes in climate have become evident through insect epidemics (e.g., Mountain Pine Beetle epidemic in Western Canada, bark beetle in secondary spruce forests in Central Europe), water shortages and intense forest fires in the Mediterranean countries (e.g., 2005 droughts in Spain), and unusual storm activities (e.g., the 2004 South-East Asia Tsunami). Climate changes are expected to impact vegetation as manifested by changes in vegetation extent, migration of species, tree species composition, growth rates, and mortality. The International Panel on Climate Change (IPCC) has included discussions on how forests may be impacted, and how they may be used to mitigate the impacts of changes in climate, to possibly slow the rate of change. This book provides current scientific information on the biological and economical impacts of climate changes in forest environments, as well as information on how forest management activities might mitigate these impacts, particularly through carbon sequestration. Case studies from a wide geographic range are presented. This information is beneficial to managers and researchers interested in climate change and impacts upon forest environments and economic activities. This volume, which forms part of Springer’s book series Managing Forest Ecosystems, presents state-of-the-art research results, visions and theories, as well as specific methods for sustainable forest management in changing climatic conditions.

Multi-Source National Forest Inventory
Author: Erkki TomppoPublisher: Springer Science & Business Media
ISBN: 1402087136
Category : Technology & Engineering
Languages : en
Pages : 383
Book Description
Building on more than a decade of innovative research into multi-source forest inventory (MS-NFI) this book presents full details of the development, outputs and applications of the improved k-NN method. The method, which was pioneered in Finland in 1990, is rapidly becoming a world standard in forest inventory, having been adopted as standard in Finland and Sweden, and recently introduced in Austria and across the US. The book describes in detail the full MS-NFI process, and the input data used – including field data, satellite images, and digital map data, as well as coarse-scale variation of forest variables. It also presents comprehensive information on the types of outputs which can be derived, including maps and statistics, describing, for example, stock volumes and development, dominant tree species, age-class distribution, and large and small-scale variation. The book will provide an invaluable resource for those involved in forest inventory, including government departments and bodies involved in forest policy, management and monitoring, forest managers, and researchers and graduate students interested in forest inventory, modelling and analysis. It will find an additional market among those interested in Earth observation, ecology and broader areas of environmental and natural resource management. Erkki Tomppo was the winner of the 1997 Marcus Wallenberg Prize for his work on the k-NN method.
