Download or read book Wildland Fire in Ecosystems written by U. S. Department Of Agriculture and published by CreateSpace. This book was released on 2012-10 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers in planning for ecosystem management and fire management, and in their efforts to inform others about the ecological role of fire. Chapter 1 presents an overview and a classification of fire regimes that is used throughout the report. Chapter 2 summarizes knowledge of fire effects on individual plants, including susceptibility to mortality of aerial crowns, stems, and roots; vegetative regeneration; seedling establishment from on-site and off-site seed sources; seasonal influences such as carbohydrates and phenological stage; and factors affecting burn severity. Five chapters describe fire regime characteristics such as fire severity, fire frequency, and fire intensity, and postfire plant community responses for ecosystems throughout the United States and Canada. Typical fuel compositions, fuel loadings, and fire behavior are described for many vegetation types. Vegetation types including Forest-Range Environmental Study (FRES), Kuchler, and Society of American Foresters (SAF) types are classified as belonging to understory, mixed, or stand replacement fire severity regime types. The severity and frequency of fire are described for the pre-Euro-American settlement period and contrasted with current fire regimes. Historic fire frequencies ranged from a fire every 1 to 3 years in some grassland and pine types to a fire every 500 to 1,000 years in some coastal forest and northern hardwood types. In many vegetation types characterized by understory fire regimes, a considerable shift in fire frequency and fire severity occurred during the past century. Successional patterns and vegetation dynamics following disturbance by fire, and in some cases related grazing and silvicultural treatments, are described for major vegetation types. Management considerations are discussed, especially for the application of prescribed fire. A chapter on global climate change describes the complexity of a changing climate and possible influences on vegetation, fuels, and fire. The uncertainty of global climate change and its interactions with vegetation means expectations for fire management are general and tentative. Nonetheless, manipulation of wildlands and disturbance regimes may be necessary to ensure continual presence of some species. The last chapter takes a broader, more fundamental view of the ecological principles and shifting fire regimes described in the other chapters. The influences of fire regimes on biodiversity and fuel accumulation are discussed. Strategies and approaches for managing fire in an ecosystem context and sources of technical knowledge that can assist in the process are described. Research needs are broadly summarized.

Book Synopsis Tropical Fire Ecology by : Mark Cochrane
Download or read book Tropical Fire Ecology written by Mark Cochrane and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.
Download or read book Vegetation Dynamics written by J. Miles and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetation dynamics is an important subject. A knowledge and under standing of it is central to the science of vegetation management-in grassland, range and nature reserve management, and in aspects of wildlife management, forestry and agricultural crop production. It is also a large and diffuse subject. In a small book such as this I had to be highly selective, and could not do equal justice to all aspects. I have had therefore to condense many examples, and more regrettably, many arguments. While I have tried to present a broad selection of topics and examples, the content inevitably reflects my own special interests and experience. The study of vegetation and its dynamics does not lend itselfto neat and tidy divisions, and the way of allotting material into different chapters here is arbitrary. I have used Chapter I to introduce a number of ideas, beginning with the nature of vegetation in space, then passing to an introduction to the nature of changes in vegetation with time, in particular those generally known as successions. The book also contains a number of asides to the text's central arguments; I hope the reader finds these interesting rather than disconcerting.

Book Synopsis The Ecology of Fire by : Robert J. Whelan
Download or read book The Ecology of Fire written by Robert J. Whelan and published by Cambridge University Press. This book was released on 1995-08-10 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildfires kill many animals, but are populations of animals affected? How do animals survive the passage of fire? Why do some tree species survive and others die in a fire? Do frequent fires cause changes in plant community composition? Answering questions such as these requires an understanding of the ecological effects of fire. Aimed at senior undergraduate students, researchers, foresters and other land managers, Dr Whelan's book examines the changes wrought by fires with reference to general ecological theory. The impacts of fires on individual organisms, populations and communities are examined separately, and emphasis is placed on the importance of fire regime. Each chapter includes a listing of 'outstanding questions' that identify gaps in current knowledge. The book finishes by summarising the major aspects of ecology that are of particular relevance to management of fires - both protection against wildfires and deliberate use of fire.
Book Synopsis Vegetation Dynamics on the Mountains and Plateaus of the American Southwest by : John Vankat
Download or read book Vegetation Dynamics on the Mountains and Plateaus of the American Southwest written by John Vankat and published by Springer Science & Business Media. This book was released on 2013-05-27 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Book Synopsis Quaternary Vegetation Dynamics of Europe by : Gerhard Lang
Download or read book Quaternary Vegetation Dynamics of Europe written by Gerhard Lang and published by Haupt Verlag. This book was released on 2023-06-12 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on palaeoecological studies by many authors, this book gives an overview of the changing history of the European plant cover during the past 2.6 million years, characterized by numerous cold and warm periods. The period of the last 20 000 years (from the Last Glacial Maximum to the present) is presented in detail, with special emphasis on the vegetation dynamics of Europe, the history of selected woody plants, the development of lakes and bogs and the emergence of European cultural landscapes under the influence of humans over thousands of years. In the analysis of the glacial and interglacial periods, the focus is on the different vegetation developments and the progressive impoverishment of the European flora. Further important topics are the spatio-temporal patterns and causes of long-term vegetation changes, the legacies of disturbances and land use on vegetation composition, the role of palaeoecology in nature conservation and its contribution to ecology and environmental sciences. In addition to recent research results, the book provides an overview of the main palaeoecological research methods. It concludes with a summary of the history of palaeoecology and Quaternary botany. For the first time, a detailed synthesis is presented of the many findings on European vegetation dynamics, which are complex and increasingly difficult to summarize. Numerous figures and tables, many of them original, accompany the text. The bibliography includes over 3000 publications. This book is primarily intended for students, researchers and practitioners in plant ecology, palaeoecology, palaeoclimatology, forestry, agronomy, Quaternary sciences, climate sciences, biogeography, geography and archaeology.
Book Synopsis The Firebgcv2 Landscape Fire Succession Model by : United States Department of Agriculture
Download or read book The Firebgcv2 Landscape Fire Succession Model written by United States Department of Agriculture and published by CreateSpace. This book was released on 2015-02-14 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire management faces important emergent issues in the coming years such as climate change, fire exclusion impacts, and wildland-urban development, so new, innovative means are needed to address these challenges. Field studies, while preferable and reliable, will be problematic because of the large time and space scales involved. Therefore, landscape simulation modeling will have more of a role in wildland fire management as field studies become untenable.
Book Synopsis Vegetation Dynamics and the Efficacy of Prescribed Fires in Restoring Oak-dominated Ecosystems in Southern Ohio by : Sheryl M. Petersen
Download or read book Vegetation Dynamics and the Efficacy of Prescribed Fires in Restoring Oak-dominated Ecosystems in Southern Ohio written by Sheryl M. Petersen and published by . This book was released on 2012 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most pryrogenic ecosystems are endangered due to encroachment of fire-sensitive species and loss of fire-tolerant species caused by altered fire regimes, especially fire suppression. Restoration of these degraded systems typically involves the reintroduction of fire via prescribed burning. I evaluated the efficacy of prescribed fire in reducing woody plant encroachment in fire-suppressed oak-dominated ecosystems in the Bluegrass Region of southern Ohio. In the first study, I tested the effects of biennial fire and a fire surrogate (clipping) on woody and herbaceous vegetation abundance in oak barrens. I found that fire and clipping produce similar responses in vegetation, and although these treatments reduce the aerial cover of shrubs, they do not lessen shrub resprouting or promote herbaceous plants. Next, I described the characteristics of oak-dominated forests prior to the reintroduction of fire. My snapshot of seedling layer vegetation in these forests highlights the variation in vegetation and environmental factors over small and large spatial scales. Despite their distinctions in composition, the structural patterns at all the forest stands provide evidence for a general shift in composition from oak (Quercus) to maple (Acer) dominance. Oaks are failing to regenerate and are being replaced by actively recruiting maples. Fires are predicted to reverse this shift by acting as a filter for maples resulting in the promotion oaks. In my final study, I tested this prediction and evaluated the effects of fire season and topkill with and without heating on forest seedling composition and abundance. I found no clear effect of fire season, or heating, and only limited support for the prediction that fires act as a filter for maples. Overall, these results indicate that fire might maintain initial vegetation conditions, but is not effective in reversing encroachment in oak-dominated ecosystems. Despite the limited spatial and temporal scale of my studies, these results are consistent with the general findings in the literature. They underscore the need to test multiple aspects of the fire regime (frequency, intensity, and season) in concert with structural manipulations. They also suggest that we may need to modify our expectation that fire will restore these highly altered systems.
Book Synopsis Fire and Climatic Change in Temperate Ecosystems of the Western Americas by : Thomas T. Veblen
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
Book Synopsis Global and Regional Vegetation Fire Monitoring from Space by : Frank J. Ahern
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).
