This book was released on with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire history and fire-climate relationships of upper elevation forests of the southwestern United States are imperative for informing management decisions in the face of increased crown fire occurrence and climate change. I used dendroecological techniques to reconstruct fires and stand-replacing fire patch size in the Madrean Sky Islands and Mogollon Plateau. Reconstructed patch size (1685-1904) was compared with contemporary patch size (1996-2004). Reconstructed fires at three sites had stand-replacing patches totaling>500 ha. No historical stand-replacing fire patches were evident in the mixed conifer/aspen forests of the Sky Islands. Maximum stand-replacing fire patch size of modern fires (1129 ha) was greater than that reconstructed from aspen (286 ha) and spruce-fir (521 ha). Undated spruce-fir patches may be evidence of larger (>2000ha) stand-replacing fire patches. To provide climatological context for fire history I used correlation and regionalization analyses to document spatial and temporal variability in climate regions, and El-Nił̧o Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO) and the Atlantic Multi-decadal Oscillation (AMO) teleconnections using 273 tree-ring chronologies (1732 - 1979). Four regions were determined by common variability in annual ring width. The component score time series replicate spatial variability in 20th century droughts (e.g., 1950's) and pluvials (e.g., 1910's). Two regions were significantly correlated with instrumental SOI and AMO, and three with PDO. Sub-regions within the southwestern U.S. varied geographically between the instrumental (1900-1979) and the pre-instrumental periods (1732-1899). Mapped correlations between ENSO, PDO and AMO, and tree-ring indices illustrate detailed sub-regional variability in the teleconnections. I analyzed climate teleconnections, and fire-climate relationships of historical upper elevation fires from 16 sites in 8 mountain ranges. I tested for links between Palmer Drought Severity Index and tree-ring reconstructed ENSO, PDO and AMO phases (1905-1978 and 1700-1904). Upper elevation fires (115 fires, 84 fire years, 1623-1904) were compared with climate indices. ENSO, PDO, and AMO affected regional PDSI, but AMO and PDO teleconnections changed between periods. Fire occurrence was significantly related to inter-annual variability in PDSI, precipitation, ENSO, and phase combinations of ENSO and PDO, but not AMO (1700-1904). Reduced upper elevation fire (1785-1840) was coincident with a cool AMO phase.

This book was released on 2006-05-10 with total page 456 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.
Download or read book Fire Ecology and Management Past Present and Future of US Forested Ecosystems written by Cathryn H. Greenberg and published by Springer Nature. This book was released on 2021-10-01 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.

Available in PDF, EPUB and Kindle. Book excerpt: The devastating fire that swept through Los Alamos, New Mexico, in the spring of 2000 may have been caused by one controlled burn gone wild, but it was far from an isolated event. All through the twentieth century, our national forests have been under assault from all sides: first ranchers and loggers laid their claims to our national forests, then recreationists and environmentalists spoke up for their interests. Who are our national forests really for? In this book, leading environmental historians show us what has been happening to these fragile woodlands. Taking us from lumber towns to Indian reservations to grazing lands, Forests under Fire reveals the interaction of Anglos, Hispanics, and Native Americans with the forests of the American Southwest. It examines recent controversies ranging from red squirrel conservation on Mt. Graham to increased tourism in our national forests. These case studies offer insights into human-forest relationships in places such as the Coconino National Forest, the Vallecitos Sustained Yield Unit, and the Gila Wilderness Area while also drawing on issues and concerns about similar biospheres in other parts of the West. Over the past century, forest management has evolved from a field dominated by the "conservationist" perspective—with humans exploiting natural resources-to one that emphasizes biocentrism, in which forests are seen as dynamic ecosystems. Yet despite this progressive shift, the assault on our forests continues through overgrazing of rangelands, lumbering, eroding mountainsides, fire suppression, and threats to the habitats of endangered species. Forests under Fire takes a closer look at the people calling the shots in our national forests, from advocates of timber harvesting to champions of ecosystem management, and calls for a reassessment of our priorities—before our forests are gone.

Download or read book Fire Management in the American West written by Mark Hudson and published by University Press of Colorado. This book was released on 2011-11-01 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most journalists and academics attribute the rise of wildfires in the western United States to the USDA Forest Service's successful fire-elimination policies of the twentieth century. However, in Fire Management in the American West, Mark Hudson argues that although a century of suppression did indeed increase the hazard of wildfire, the responsibility does not lie with the USFS alone. The roots are found in the Forest Service's relationships with other, more powerful elements of society--the timber industry in particular. Drawing on correspondence both between and within the Forest Service and the major timber industry associations, newspaper articles, articles from industry outlets, and policy documents from the late 1800s through the present, Hudson shows how the US forest industry, under the constraint of profitability, pushed the USFS away from private industry regulation and toward fire exclusion, eventually changing national forest policy into little more than fire policy. More recently, the USFS has attempted to move beyond the policy of complete fire suppression. Interviews with public land managers in the Pacific Northwest shed light on the sources of the agency's struggles as it attempts to change the way we understand and relate to fire in the West. Fire Management in the American West will be of great interest to environmentalists, sociologists, fire managers, scientists, and academics and students in environmental history and forestry.

Available in PDF, EPUB and Kindle. Book excerpt: This document provides managers with a literature synthesis of the historical conditions, current conditions, fire regime condition classes (FRCC), and recommended treatments for the major ecosystems in southern Utah. Sections are by ecosystems and include: 1) coniferous forests (ponderosa pine, mixed conifer, and Engelmann spruce-subalpine fir), 2) aspen, 3) pinyon-juniper, 4) big and black sagebrush, and 5) desert shrubs (creosotebush, blackbrush, and interior chaparral). Southern Utah is at the ecological crossroads for much of the western United States. It contains steep environmental gradients and a broad range of fuels and fire regimes associated with vegetation types representative of the Rocky Mountains, the Great Basin, Northern Arizona and New Mexico, and the Mohave Desert. The Southern Utah Demonstration Area consists of contiguous state and federal lands within the administrative boundaries of the Bureau of Land Management (BLM), Fishlake and Dixie National Forests, National Park Sevice, and State of Utah, roughly encompassing the southern 15 percent of Utah (3.24 million ha). The vegetation types described are similar in species composition, stand structure, and ecologic function, including fire regime to vegetation types found on hundreds of millions of hectares in the 11 western states.

This book was released on 2018-03-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prescribed burning is an important tool throughout Southern forests, grasslands, and croplands. The need to control fire became evident to allow forests to regenerate. This manual is intended to help resource managers to plan and execute prescribed burns in Southern forests and grasslands. A new appreciation and interest has developed in recent years for using prescribed fire in grasslands, especially hardwood forests, and on steep mountain slopes. Proper planning and execution of prescribed fires are necessary to reduce detrimental effects, such as the impacts on air and downstream water quality.

Download or read book Flames in Our Forest written by Stephen F. Arno and published by Island Press. This book was released on 2013-04-10 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shaped by fire for thousands of years, the forests of the western United States are as adapted to periodic fires as they are to the region's soils and climate. Our widespread practice of ignoring the vital role of fire is costly in both ecological and economic terms, with consequences including the decline of important fire-dependent tree and undergrowth species, increasing density and stagnation of forests, epidemics of insects and diseases, and the high potential for severe wildfires. Flames in Our Forest explains those problems and presents viable solutions to them. It explores the underlying historical and ecological reasons for the problems associated with our attempts to exclude fire and examines how some of the benefits of natural fire can be restored Chapters consider: the history of American perceptions and uses of fire in the forest how forest fires burn effects of fire on the soil, water, and air methods for uncovering the history and effects of past fires prescribed fire and fuel treatments for different zones in the landscape Flames in Our Forest presents a new picture of the role of fire in maintaining forests, describes the options available for restoring the historical effects of fires, and considers the implications of not doing so. It will help readers appreciate the importance of fire in forests and gives a nontechnical overview of the scientific knowledge and tools available for sustaining western forests by mimicking and restoring the effects of natural fire regimes.
