Book Description
A troubling story of the devastating and compounding effects of climate change in the Western and Rocky Mountain states, told through in–depth reportage and conversations with ecologists, professional forest managers, park service scientists, burn boss, activists, and more. Climate change manifests in many ways across North America, but few as dramatic as the attacks on our western pine forests. In Trees in Trouble, Daniel Mathews tells the urgent story of this loss, accompanying burn crews and forest ecologists as they study the myriad risk factors and refine techniques for saving this important, limited resource. Mathews transports the reader from the exquisitely aromatic haze of ponderosa and Jeffrey pine groves to the fantastic gnarls and whorls of five–thousand–year–old bristlecone pines, from genetic test nurseries where white pine seedlings are deliberately infected with their mortal enemy to the hottest megafire sites and neighborhoods leveled by fire tornadoes or ember blizzards. Scrupulously researched, Trees in Trouble not only explores the devastating ripple effects of climate change, but also introduces us to the people devoting their lives to saving our forests. Mathews also offers hope: a new approach to managing western pine forests is underway. Trees in Trouble explores how we might succeed in sustaining our forests through the challenging transition to a new environment.

Book Description
Fire, in conjunction with landforms and climate, shapes the structure and function of forests throughout the Western United States, where millions of acres of forest lands contain accumulations of flammable fuel that are much higher than historical conditions owing to various forms of fire exclusion. The Healthy Forests Restoration Act mandates that public land managers assertively address this situation through active management of fuel and vegetation. This document synthesizes the relevant scientific knowledge that can assist fuel-treatment projects on national forests and other public lands and contribute to National Environmental Policy Act (NEPA) analyses and other assessments. It is intended to support science-based decisionmaking for fuel management in dry forests of the Western United States at the scale of forest stands (about 1 to 200 acres). It highlights ecological principles that need to be considered when managing forest fuel and vegetation for specific conditions related to forest structure and fire hazard. It also provides quantitative and qualitative guidelines for planning and implementing fuel treatments through various silvicultural prescriptions and surfacefuel treatments. Effective fuel treatments in forest stands with high fuel accumulations will typically require thinning to increase canopy base height, reduce canopy bulk density, reduce canopy continuity, and require a substantial reduction in surface fuel through prescribed fire or mechanical treatment or both. Long-term maintenance of desired fuel loadings and consideration of broader landscape patterns may improve the effectiveness of fuel treatments.

Book Description
This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)-- illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy.

Book Description
Climate change poses a huge threat to the West. The current mountain pine beetle epidemic with over 50 million acres of dying trees in western North America has created a powerful “teachable moment” across the region. A primary goal of the Forests At Risk symposium was to reframe the nation’s climate change dialogue by making the issue both personal and real to many who may not appreciate its connection to the immediate world around them. While some may have difficulty relating to rising sea levels, falling water tables, imperiled polar bears and melting glaciers in far-off places, they are still shocked by the sight of vast dying forests around their homes. The Forests At Risk symposium explored the statement by Andy Jacobson, a carbon cycle scientist at the National Oceanic and Atmospheric Administration in Boulder, that “this is the kind of feedback we're all very worried about in the carbon cycle ... a warming planet leading to, in this case, an insect outbreak that increases carbon dioxide into the atmosphere, which can increase warming.” The overwhelming scientific consensus holds that climate change is one of the most serious threats facing humankind today. We have a soberingly short time in which to reduce atmospheric greenhouse gases if we are to preserve our quality of life and environment. In addition to the global urgency, the American West is deeply dependent on the health of its forests, mountains and streams for both its quality of life and its economy. Put simply, if global warming shortens our winters, diminishes our recreation, and unleashes wildfires, diseases and insect epidemics that devastate our forests, the regional damage would be incalculable. NOW is the perfect time to learn more in this ebook. The Forests At Risk symposium represented the first substantial public forum focused directly on the connection between climate change and forest health in the American West. In the wake of millions of acres of pine beetle devastation across our continent, this is the ideal moment to highlight the climate change connection and focus on the question of what happens when our forests transform from carbon sinks into carbon sources.

Book Description
"Frightening...Firestorm comes alive when Struzik discusses the work of offbeat scientists." —New York Times Book Review "Comprehensive and compelling." —Booklist "A powerful message." —Kirkus "Should be required reading." —Library Journal For two months in the spring of 2016, the world watched as wildfire ravaged the Canadian town of Fort McMurray. Firefighters named the fire “the Beast.” It acted like a mythical animal, alive with destructive energy, and they hoped never to see anything like it again. Yet it’s not a stretch to imagine we will all soon live in a world in which fires like the Beast are commonplace. A glance at international headlines shows a remarkable increase in higher temperatures, stronger winds, and drier lands– a trifecta for igniting wildfires like we’ve rarely seen before. This change is particularly noticeable in the northern forests of the United States and Canada. These forests require fire to maintain healthy ecosystems, but as the human population grows, and as changes in climate, animal and insect species, and disease cause further destabilization, wildfires have turned into a potentially uncontrollable threat to human lives and livelihoods. Our understanding of the role fire plays in healthy forests has come a long way in the past century. Despite this, we are not prepared to deal with an escalation of fire during periods of intense drought and shorter winters, earlier springs, potentially more lightning strikes and hotter summers. There is too much fuel on the ground, too many people and assets to protect, and no plan in place to deal with these challenges. In Firestorm, journalist Edward Struzik visits scorched earth from Alaska to Maine, and introduces the scientists, firefighters, and resource managers making the case for a radically different approach to managing wildfire in the 21st century. Wildfires can no longer be treated as avoidable events because the risk and dangers are becoming too great and costly. Struzik weaves a heart-pumping narrative of science, economics, politics, and human determination and points to the ways that we, and the wilder inhabitants of the forests around our cities and towns, might yet flourish in an age of growing megafires.

Book Description
Wildland fires are one of the most devastating and terrifying forces of nature. While their effects are mostly destructive they also help with regeneration of forests and other ecosystems. Low-intensity fires clear accumulating biomass reducing risk of catastrophic crown fires and can be used as an effective management tool. This book presents current understanding of wildland fires and air quality as well as their effects on human health, forests and other ecosystems. in the first section of the book the basics of wildland fires and resulting emissions are presented from the perspective of changing global climate, air quality impairment and effects on environmental and human health and security. in the second section, effects of wildland fires on air quality, visibility and human health in various regions of the Earth are discussed. The third section of the book deals with complex issues of the ecological impacts of fires and air pollution in forests and chaparral in North America. The fourth section discusses various management issues facing land and fire managers which are related to wildfires, use of prescribed fires, and air quality. This section also presents various modeling systems used for describing fire dangers and behavior as well as smoke and air pollution predictions applied in the risk assessment analysis. The book concludes with a series of expert recommendations for wildland fire and atmospheric research.
