Download or read book Soil Respiration in a Fire Scar Chronosequence of Canadian Boreal Jack Pine Forest written by Daniel Robert Smith and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigates soil respiration (Rs) in a boreal jack pine (Pinus banksiana Lamb.) fire scar chronosequence at Sharpsand Creek, Ontario, Canada. During two field campaigns in 2006 and 2007, Rs was measured in a chronosequence of fire scars in the range 0 to 59 years since fire. Mean Rs adjusted for soil temperature (Ts) and soil moisture (Ms) (Rs T, M) ranged from 0.56?mol CO2/m2/s (32 years post fire) to 8.18?mol CO2/m2/s (58 years post fire). Coefficient of variation (CV) of Rs adjusted for Ts and Ms ranged from 20% (16 years post fire) to 56% (58 years post fire). Across the field site, there was a significant exponential relationship between Rs adjusted for soil organic carbon (Cs) and Ts (P = 1.24*10-06; Q10 = 2.21) but no effect of Ms on Rs adjusted for Cs and Ts for the range 0.21 to 0.77 volumetric Ms (P = 0.702). Rs T, M significantly (P = 0.030) decreased after burning mature forest, though no significant (P> 0.1) difference could be detected between recently burned and unburned young forest. Rs was measured in recently burned boreal jack pine fire scar age categories that differed in their burn history and there was a significant difference in Rs T, M between previously 32 v 16 year old (P = 0.000) and previously 32 v 59 year old (P = 0.044) scars. There was a strong significant exponential increase in S R T, M with time since fire (r2 = 0.999; P = 0.006) for the chronosequence 0, 16 and 59 years post fire, and for all these age categories, Rs T, M was significantly different from one another (P
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.

Download or read book Global and Regional Vegetation Fire Monitoring from Space written by Frank J. Ahern and published by Kugler Publications. This book was released on 2001 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction Increasing conflagrations of forests and other lands throughout the world during the 1980s and 1990s have made fires in forest and other vegetation emerge as an important global concern. Both the number and severity of wildfires (accidental fires) and the application of fire for land-use change, seem to have increased dramatically compared to previous decades of the twentieth century. The adverse consequences of extensive wildfires cross national boundaries and have global impacts. Fire regimes are changing with climate variability and population dynamics. Satellite remote sensing technology has the potential to play an important role for monitoring fires and their consequences, as well as in operational fire management. In response to this need as well as to respond to other needs for more rapid progress in forest observation, in 1997 the Committee on Earth Observation Satellites (CEOS) initiated Global Observation of Forest Cover (GOFC) as an international pilot project to test the concepts of an Integrated Global Observing System. The GOFC program is currently part of the Global Terrestrial Observing System (GTOS). GOFC was designed to bring together data providers and information users to make information products from satellite and in-situ observations of forests more readily available worldwide. Fire Monitoring and Mapping was formed as one of three basic components of GOFC. This book contains eighteen contributions authored by scientists who represent the most active international research and development institutions, aiming at coordinating and improving international efforts for user-oriented systems and products. These papers were initially presented at a GOFC Fire Workshop held at the Joint Research Centre, Ispra. The volume is a contribution of the GOFC Forest Fire Monitoring and Mapping Implementation Team to the Interagency Task Force Working Group Wildland Fire of the UN International Strategy for Disaster Reduction (ISDR).

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.
Download or read book Forest fire scar Aging Using SPOT VEGETATION for Canadian Ecoregions written by and published by . This book was released on 2003 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing techniques can aid in forest fire mapping, especially in remote areas and during busy fire seasons. The SPOT-VEGETATION (SV) sensor has previously shown promise at distinguishing fire scars on the landscape. This paper evaluates the usefulness of the SV sensor to age fires in 18 Canadian ecoregions for a period of up to 50 years since fire. The SV reflectances were evaluated using the ratio of the short wave infrared band to near infrared band, compared with the Canadian large-fire database. Results show the dependence of fire-scar age prediction on ecoregion and on time following fire. Applications, limitations, & uncertainties of the SV data are discussed.
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 400 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.
Download or read book Biomass Burning and Its Inter Relationships with the Climate System written by John L. Innes and published by Springer Science & Business Media. This book was released on 2000 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of scientific papers which were presented at an international workshop held in Wengen, Switzerland, in September 1998. A number of state-of-the-art papers are presented, which discuss scientific, technological and socio-economic issues related to large forest fires which occur both in the tropics and in the extra-tropical regions. The book comprises some of the most recent research conducted in the context of the large forest fires which occurred in South-East Asia, Australia, Brazil and Africa in late 1997 and early 1998; while essentially due to human interference, these particular fires appear to have been enhanced by the particularly strong El Niño episode which prevailed at that time. This interdisciplinary volume addresses a number of topics, in particular the contribution to climatic change by the greenhouse gases and aerosols emitted by large forest fires, the monitoring of fires both during and after combustion through satellite remote-sensing techniques, and numerical studies of the perturbation to the climate system using general circulation climate models.
