The Changing Nature of the Maine Woods
The ecology of the ever-changing Maine forest
Forests Adrift
A captivating analysis of the past, present, and future of northeastern forests and the forces that have shaped them The northeastern United States is one of the most densely forested regions in the country, yet its history of growth, destruction, and renewal are for the most part poorly understood—even by specialists. In this engaging look at both the impermanence and the resilience of the northeastern forest ecosystems, Charles D. Canham provides a synthesis of modern ecological research and explores critical threats that include logging, fire suppression, disease, air pollution, invasive species, and climate change. Providing a historical perspective on how northeastern forests have changed since the arrival of European settlers, Canham also utilizes new theoretical models to predict how these ecosystems will change and adapt to an uncertain future. This is an informed and accessible investigation of an endangered natural landscape that examines the ramifications of the scientific controversies and ethical dilemmas shaping the future of northeastern forests.
Where the Great River Rises
A lavishly illustrated, comprehensive, interdisciplinary study of the natural and human elements that comprise the Upper Connecticut River watershed
Ecology and Decline of Red Spruce in the Eastern United States
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 ...
White Pine
America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation’s ships and houses, barns, and bridges. It became a symbol of independence, adorning the Americans’ flag at Bunker Hill, and an economic engine, generating three times more wealth than the California gold rush. Yet this popularity came at a cost: by the end of the 19th century, clear cutting had decimated much of America’s white pine forests. In White Pine: The Natural and Human History of a Foundational American Tree, ecologist and writer John Pastor takes readers on walk through history, connecting the white pine forests that remain today to a legacy of destruction and re...
Rediscovering the Maine Woods
The Maine Woods, vast and largely unsettled, are often described as unchanged since Henry David Thoreau's journeys across the backcountry, in spite of the realities of Indian dispossession and the visible signs of logging, settlement, tourism, and real estate development. In the summer of 2014 scholars, activists, members of the Penobscot Nation, and other individuals retraced Thoreau's route. Inspired partly by this expedition, the accessible and engaging essays here offer valuable new perspectives on conservation, the cultural ties that connect Native communities to the land, and the profound influence the geography of the Maine Woods had on Thoreau and writers and activists who followed in his wake. Together, these essays offer a rich and multifaceted look at this special place and the ways in which Thoreau's Maine experiences continue to shape understandings of the environment a century and a half later. Contributors include the volume editor, Kathryn Dolan, James S. Finley, James Francis, Richard W. Judd, Dale Potts, Melissa Sexton, Chris Sockalexis, Stan Tag, Robert M. Thorson, and Laura Dassow Walls.
Biogeochemistry of a Forested Ecosystem
The goal of this Third Edition is to update long-term data presented in earlier editions and to generate new syntheses and conclusions about the biogeochemistry of the Hubbard Brook Valley based on these longer-term data. There have been many changes, revelations, and exciting new insights generated from the longer data records. For example, the impact of acid rain peaked during the period of the HBES and is now declining. The longer-term data also posed challenges in that very marked changes in fluxes occurred in some components, such as hydrogen ion and sulfate deposition, calcium and nitrate export in stream water and biomass accumulation, during the almost 50 years of record. Thus, prese...
