Book Description
"Since the early 1960s, the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire has been one of the most comprehensively studied landscapes on earth. This book highlights many of the important ecological findings amassed during the long-term research conducted there, and considers their regional, national, and global implications." -- P.2 of cover.

Book Description
S2Two even-age management systems, progressive strip cutting and block clearcutting, have been studied since 1970 on small watersheds at the Hubbard Brook Experimental Forest, New Hampshire. In the strip cutting, all merchantable trees were harvested in a series of three strips over 4 years (1970-74). In the block clearcutting, all trees were harvested in a single operation in 1970. This paper contrasts progressive strip cutting and block clearcutting for the 10-year period after initiation of harvest in terms of hydrologic response, erosion losses, stream water ions, nutrient leaching, nutrient removals in harvested products, and natural regeneration of vegetation.S3.

Book Description
A comprehensive guide to effective hardwood forest management Extending 235,000 square miles from New York to Georgia and fromVirginia to Missouri, the Central Hardwoods Region harbors the mostextensive concentration of deciduous hardwoods in the world. Asharvests in the Pacific Northwest decline and timber prices rise,the maturing stands of mixed species in this central U.S. regionare a rich and valuable resource that is increasingly vulnerable toexploitation. This timely book examines all of the key ecological,social, and economic management considerations essential to utilizeand sustain these vital woodlands effectively. First, it develops the background necessary to understand whatmakes the hardwood eco-system function, with a thorough examinationof the physiography, geology, soils, and climate of the region anda historical overview of its evolution and development frompre-European settlement to the present. Then, species by species,the book details the silvical characteristics of 34 important treespecies. Next, it offers expert recommendations for effectiveforest treatment and management, from specific concerns such astimber production, pollution, and financial planning to broaderissues, including the role of the natural resource manager and thebiological potential of the entire region. Generously supplemented with graphs and photos, Ecology andManagement of Central Hardwood Forests is important reading forforesters, natural resource managers, regional planners,environmental scientists, governmental officials--everyone with astake in the future of this critical living resource.

Book Description
The advent of ecosystem ecology has created great difficulties for ecologists primarily trained as biologists, since inevitably as the field grew, it absorbed components of other disciplines relatively foreign to most ecologists yet vital to the understanding of the structure and function of ecosystems. From the point of view of the biological ecologist struggling to understand the enormous complexity of the biological functions within an ecosystem, the added necessity of integrating biology with geochemis try, hydrology, micrometeorology, geomorphology, pedology, and applied sciences (like silviculture and land use management) often has appeared as an impossible requirement. Ecologists have frequently responded by limiting their perspective to biology with the result that the modeling of species interactions is sometimes considered as modeling ecosystems, or modeling the living fraction of the ecosystems is considered as modeling whole ecosystems. Such of course is not the case, since understanding the structure and function of ecosystems requires sound understanding of inanimate as well as animate processes and often neither can be under stood without the other. About 15 years ago, a view of ecology somewhat different from most then prevailing, coupled with a strong dose of naivete and a sense of exploration, lead us to believe that consideration of the inanimate side of ecosystem function rather than being just one more annoying complexity might provide exceptional advantages in the study of ecosystems. To examine this possibility, we took two steps which occurred more or less simultaneously.

Book Description
About 15 years ago we began the Hubbard Brook Ecosys tem Study with the development of an ecosystem model and the conception of a method whereby some major parameters of the model could be directly measured under field conditions. The method, called "the small watershed technique," allowed measurement of input and output of chemicals and the construction of ecosystem nutrient bud gets. Although the Hubbard Brook study of nutrient cycling originated with ideas developed by F. H. Bormann and G. E. Likens, its early growth was aided by the remaining authors of this volume-Robert Pierce, forest hydrologist; Noye Johnson, geochemist; and John Eaton, forest ecologist. Donald W. Fisher of the United States Geological Survey also cooperated in the early phases of the project and provided numerous data on the chemistry of precipitation and stream water. Particular credit is due the United States Forest Service, whose scientists chose the Hubbard Brook Valley as a hydrologic study site, selected particular watersheds for intensive measurement, carried out a variety of basic hydrologic studies, and in general cooperated with us in many ways to make the Hubbard Brook Ecosystem Study a reality. The initial part of the ecosystem study was concerned primarily with nutrient flux and cycling and it was done slowly and deliberately. The entire effort during the first few years of study was carried forward by three of us at vi Preface Dartmouth College with the cooperation of the United States Forest Service.

Book Description
Tongass Odyssey is a biologist’s memoir of personal experiences over the past four decades studying brown bears, deer, and mountain goats and advocating for conservation of Alaska’s Tongass National Forest. The largest national forest in the nation, the Tongass encompasses the most significant expanse of intact old-growth temperate rainforest remaining on Earth. Tongass Odyssey is a cautionary tale of the harm that can result when science is eclipsed by politics that are focused on short-term economic gain. Yet even as those problems put the Tongass at risk, the forest also represents a unique opportunity for conserving large, intact landscapes with all their ecological parts, including wild salmon, bears, wolves, eagles, and other wildlife. Combining elements of personal memoir, field journal, natural history, conservation essay, and philosophical reflection, Tongass Odyssey tells an engaging story about an enchanting place.
