This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s there were several published reports of recent, unexplained increases in mortality of red spruce in the Adirondack Mountains and the northern Appalachian Mountains of the eastern United States. These reports coincided with documentation of reductions in radial growth of several species of pine in the southeastern United States, and with the severe, rapid, and widespread decline of Norway spruce, silver fir, and some hardwoods in central Europe. In all of these instances, atmospheric deposition was hypothesized as the cause of the decline. (Throughout this volume, we use the term "decline" to refer to a loosely synchronized regional-scale deterioration of tree health which is brought about by a combination of stress factors. These may be biotic or abiotic in nature, and the combinations may differ from site to site. ) Heated public debate about the causes and possible cures for these forest declines ensued. Through the course of this debate, it became clear that information about forest health and air pollution effects on forests was inadequate to meet policymakers' needs. Ecology and Decline of Red Spruce in the Eastern United States addresses that gap for eastern spruce fir forests and represents the culmination of a great deal of research conducted in recent years. The focus is on red spruce because the decline of red spruce was both dramatic and inexplicable and because of the great amount of information gathered on red spruce.

Available in PDF, EPUB and Kindle. Book excerpt: During the second half of the twentieth century, the forest industry removed more than 300 billion cubic feet of timber from southern forests. Yet at the same time, partnerships between public and private entities improved the inventory, health, and productivity of this vast and resilient resource. A comprehensive and multilayered history, Forestry in the U.S. South explores the remarkable commercial and environmental gains made possible through the collaboration of industry, universities, and other agencies. This authoritative assessment starts by discussing the motives and practices of early lumber companies, which, having exhausted the forests of the Northeast by the turn of the twentieth century, aggressively began to harvest the virgin pine of the South, with production peaking by 1909. The rapidly declining supply of old-growth southern pine triggered a threat of timber famine and inspired efforts to regulate the industry. By mid-century, however, industrial forestry had its own profit incentive to replenish harvested timber. This set the stage for a unique alliance between public and private sectors, which conducted cooperative research on tree improvement, fertilization, seedling production, and other practices germane to sustainable forest management. By the close of the 1990s, concerns about an inadequate timber supply gave way to questions about how to utilize millions of acres of pine plantations approaching maturity. No longer concerned with the future supply of raw material and facing mounting global competition the U.S. pulp and paper industry consolidated, restructured, and sold nearly 20 million acres of forests to Timber Investment Management Organizations (TIMOs) and Real Estate Investment Trusts (REITs), resulting in an entirely new dynamic for private forestry in the South. Incomparable in scope, Forestry in the U.S. South spotlights the people and organizations responsible for empowering individual forest owners across the region, tripling the production of pine stands and bolstering the livelihoods of thousands of men and women across the South.

This book was released on 2013-11-11 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade there has been considerable interest in the effects of atmospheric deposition on forest ecosystems. This volume summarizes the results of the Integrated Forest Study (IFS), one of the most comprehensive research programs conducted. It involved intensive measurements of deposition and nutrient cycling at seventeen diverse forested sites in the United States, Canada, and Norway. The IFS is unique as an applied research project in its complete, ecosystem-level evaluation of nutrient budgets, including significant inputs, outputs, and internal fluxes. It is also noteworthy as a more basic investigation of ecosystem nutrient cycling because of its incorporation of state-of-the-art methods, such as quantifying dry and cloud water deposition. Most significantly, the IFS data was used to test several general hypotheses regarding atmospheric deposition and its effects. The data sets also allow for far-reaching conclusions because all sites were monitored over the same period using comparable instruments and standardized protocols.
