This book was released on 2011-07 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the use of high resolution aerial photography as an alternative to traditional field sampling methods for assessing post-fire residual structure. High resolution photography (HRP), also termed large scale photography (LSP), refers to aerial photographs interpreted at scales of 1:25,000 or larger. Eleven fires were selected for sampling across boreal Ontario in 2005. Within fires, HRP was used to sample residual structure, i.e., trees, snags, and downed wood, in point samples of 0.05 ha circular points within one to four months post-fire ignition. Fifty field plots were established in four of the sample fires for error assessment of photo-interpretation and to allow short-term monitoring of changes in post fire residual structure. Methods used to select fires, capture and interpret sample photographs, and establish and assess field sample plots are described. The two sampling methods are compared in terms of feasibility and cost--Document.

Book Synopsis An Assessment of Tree, Snag and Downed Wood Residuals in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance by : Ajith Perera
Download or read book An Assessment of Tree, Snag and Downed Wood Residuals in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance written by Ajith Perera and published by . This book was released on 2008 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to residual tree mortality, the complement of snag and downed wood residuals increased in time. After three years, abundance of large diameter residual trees was very low, and congruent with directions provided in the NDPE guide for retaining residual trees post-harvest. Local fire intensity appeared to be the most important global determinant of occurrence of residual trees, but with an inverse relationship. Our results do not support the hypotheses that pre-burn forest cover and site conditions are reliable global predictors of residual tree occurrence."--Abstract

Book Synopsis A Proposed Method to Rank the Intensity of Boreal Forests Fires in Ontario Using Post-fire High-resolution Aerial Photographs by : T. Smith
Download or read book A Proposed Method to Rank the Intensity of Boreal Forests Fires in Ontario Using Post-fire High-resolution Aerial Photographs written by T. Smith and published by . This book was released on 2008 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire intensity is a crucial descriptor of fire behaviour that may also be an important determinant of many types of ecological dynamics. However, fire intensity has proven challenging to measure directly. Indirect estimates of fire intensity are often confounded with the ecological effects of the fire, precluding further study of the relationships between intensity and population or community dynamics. In this report, the authors describe a novel method for estimating the intensity of fires in the boreal forest of Ontario using high resolution imagery taken soon after fire. This method relies on an empirical relationship between the branch structure of fire-killed trees (crown fraction burned) and fire intensity rankings provided by the Canadian Forest Fire Behaviour Prediction System (FBP) and its field guide for fire managers. The results of the application of this method to 660 high resolution aerial photography sample plots, each 25 m in diameter, dispersed among 11 fires that occurred in the boreal forest of Ontario in 2005 are described.--Document.

Book Synopsis Fire Effects on Soil Properties by : Paulo Pereira
Download or read book Fire Effects on Soil Properties written by Paulo Pereira and published by CSIRO PUBLISHING. This book was released on 2019-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are occurring more frequently and affecting more of Earth's surface than ever before. These fires affect the properties of soils and the processes by which they form, but the nature of these impacts has not been well understood. Given that healthy soil is necessary to sustain biodiversity, ecosystems and agriculture, the impact of fire on soil is a vital field of research. Fire Effects on Soil Properties brings together current research on the effects of fire on the physical, biological and chemical properties of soil. Written by over 60 international experts in the field, it includes examples from fire-prone areas across the world, dealing with ash, meso and macrofauna, smouldering fires, recurrent fires and management of fire-affected soils. It also describes current best practice methodologies for research and monitoring of fire effects and new methodologies for future research. This is the first time information on this topic has been presented in a single volume and the book will be an important reference for students, practitioners, managers and academics interested in the effects of fire on ecosystems, including soil scientists, geologists, forestry researchers and environmentalists.

Book Synopsis Permafrost Ecosystems by : Akira Osawa
Download or read book Permafrost Ecosystems written by Akira Osawa and published by Springer Science & Business Media. This book was released on 2010-01-04 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing from a decade-long collaboration between Japan and Russia, this important volume presents the first major synthesis of current knowledge on the ecophysiology of the coniferous forests growing on permafrost at high latitudes. It presents ecological data for a region long inaccessible to most scientists, and raises important questions about the global carbon balance as these systems are affected by the changing climate. Making up around 20% of the entire boreal forests of the northern hemisphere, these ‘permafrost forest ecosystems’ are subject to particular constraints in terms of temperature, nutrient availability, and root space, creating exceptional ecosystem characteristics not known elsewhere. This authoritative text explores their diversity, structure, dynamics and physiology. It provides a comparison of these forests in relation to boreal forests elsewhere, and concludes with an assessment of the potential responses of this unique biome to climate change. The book will be invaluable to advanced students and researchers interested in boreal vegetation, forest ecology, silviculture and forest soils, as well as to researchers into climate change and the global carbon balance.
Book Synopsis Old-Growth Forests by : Christian Wirth
Download or read book Old-Growth Forests written by Christian Wirth and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many terms often used to describe old-growth forests imply that these forests are less vigorous, less productive and less stable than younger forests. But research in the last two decades has yielded results that challenge the view of old-growth forests being in decline. Given the importance of forests in battling climate change and the fact that old-growth forests are shrinking at a rate of 0.5% per year, these new results have come not a moment too soon. This book is the first ever to focus on the ecosystem functioning of old-growth forests. It is an exhaustive compendium of information that contains original work conducted by the authors. In addition, it is truly global in scope as it studies boreal forests in Canada, temperate old-growth forests in Europe and the Americas, and global tropical forests. Written in part to affect future policy, this eminently readable book is as useful for the scientist and student as it is for the politician and politically-interested layman.
Book Synopsis Alaska's Changing Boreal Forest by : F. Stuart Chapin
Download or read book Alaska's Changing Boreal Forest written by F. Stuart Chapin and published by Oxford University Press. This book was released on 2006-01-12 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at how this cold-adapted, fire-prone forest adjusts to change. This volume synthesizes current understanding of the ecology of Alaska's boreal forests and describes their unique features in the context of circumpolar and global patterns. It tells how fire and climate contributed to the biome's current dynamics. As climate warms and permafrost (permanently frozen ground) thaws, the boreal forest may be on the cusp of a major change in state. The editors have gathered a remarkable set of contributors to discuss this swift environmental and biotic transformation. Their chapters cover the properties of the forest, the changes it is undergoing, and the challenges these alterations present to boreal forest managers. In the first section, the reader can absorb the geographic and historical context for understanding the boreal forest. The book then delves into the dynamics of plant and animal communities inhabiting this forest, and the biogeochemical processes that link these organisms. In the last section the authors explore landscape phenomena that operate at larger temporal and spatial scales and integrates the processes described in earlier sections. Much of the research on which this book is based results from the Bonanza Creek Long-Term Ecological Research Program. Here is a synthesis of the substantial literature on Alaska's boreal forest that should be accessible to professional ecologists, students, and the interested public.

Book Synopsis National Forest Inventories by : Erkki Tomppo
Download or read book National Forest Inventories written by Erkki Tomppo and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest inventories throughout the world have evolved gradually over time. The content as well as the concepts and de?nitions employed are constantly adapted to the users’ needs. Advanced inventory systems have been established in many countries within Europe, as well as outside Europe, as a result of development work spanning several decades, in some cases more than 100 years. With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the reports wider. Some of the agreements made at the international level have direct impacts on national economies and international decisions, e. g. , the Kyoto Protocol. Thus it is of utmost importance that the forest information supplied is collected and analysed using sound scienti?c principles and that the information from different countries is comparable. European National Forest Inventory (NFI) teams gathered in Vienna in 2003 to discuss the new challenges and the measures needed to get data users to take full advantage of existing NFIs. As a result, the European National Forest Inventory Network (ENFIN), a network of NFIs, was established. The ENFIN members decided to apply for funding for meetings and collaborative activities. COST– European Cooperation in Science and Technology - provided the necessary ?n- cial means for the realization of the program.
Download or read book Root Ecology written by Hans de Kroon and published by Springer Science & Business Media. This book was released on 2003-05-21 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
