Book Description
Deciduous forests have been remarkably resilient throughout their history, recovering from major shifts in climate and surviving periods of massive deforestation. But today the world’s great forests confront more ominous threats than ever before. This visionary book is the first to examine forests consisting of oaks, maples, hickories, beeches, chestnuts, birches and ecologically similar animals and plants on three continents—East Asia, Europe, and North America—to reveal their common origin back in time, the ecological patterns they share, and the approaches to conservation that have been attempted on their behalf. Although these forests face common problems, threats due to human activities vary. Different land use and agricultural practices on the three continents, as well as different attitudes about what is worth preserving, have led to strikingly different approaches to forest conservation. Robert Askins explores the strengths and weaknesses of conservation efforts across the continents and concludes that the ideal strategy for the future will blend the best ideas from each.

Book Description
The treetops of the world's forests are where discovery and opportunity abound, however they have been relatively inaccessible until recently. This book represents an authoritative synthesis of data, anecdotes, case studies, observations, and recommendations from researchers and educators who have risked life and limb in their advocacy of the High Frontier. With innovative rope techniques, cranes, walkways, dirigibles, and towers, they finally gained access to the rich biodiversity that lives far above the forest floor and the emerging science of canopy ecology. In this new edition of Forest Canopies, nearly 60 scientists and educators from around the world look at the biodiversity, ecology, evolution, and conservation of forest canopy ecosystems. Comprehensive literature list State-of-the-art results and data sets from current field work Foremost scientists in the field of canopy ecology Expanded collaboration of researchers and international projects User-friendly format with sidebars and case studies Keywords and outlines for each chapter

Book Description
From the East Coast to the Mississippi River, from southern Canada to northern Florida, the eastern deciduous forest of North America is home to a wonderfully diverse range of wildlife and ecosystems. Richard H. Yahner integrates basic biological principles into an account of the ecological consequences of society's actions. As Yahner traces the history of conservation of the forest, he discusses relevant issues such as the loss of biodiversity, acid deposition, ozone depletion, and global climatic change. This new edition includes the most up-to-date information on the forest and its wildlife, with special attention given to contemporary conservation issues. The result is a timely and useful tool for anyone who wants to know or hopes to help one of North America's great natural resources.

Book Description
Before 1910 the American chestnut was one of the most common trees in the eastern United States. Although historical evidence suggests the natural distribution of the American chestnut extended across more than four hundred thousand square miles of territory—an area stretching from eastern Maine to southeast Louisiana—stands of the trees could also be found in parts of Wisconsin, Michigan, Washington State, and Oregon. An important natural resource, chestnut wood was preferred for woodworking, fencing, and building construction, as it was rot resistant and straight grained. The hearty and delicious nuts also fed wildlife, people, and livestock. Ironically, the tree that most piqued the emotions of nineteenth- and early twentieth-century Americans has virtually disappeared from the eastern United States. After a blight fungus was introduced into the United States during the late nineteenth century, the American chestnut became functionally extinct. Although the virtual eradication of the species caused one of the greatest ecological catastrophes since the last ice age, considerable folklore about the American chestnut remains. Some of the tree’s history dates to the very founding of our country, making the story of the American chestnut an integral part of American cultural and environmental history. The American Chestnut tells the story of the American chestnut from Native American prehistory through the Civil War and the Great Depression. Davis documents the tree’s impact on nineteenth-and early twentieth-century American life, including the decorative and culinary arts. While he pays much attention to the importation of chestnut blight and the tree’s decline as a dominant species, the author also evaluates efforts to restore the American chestnut to its former place in the eastern deciduous forest, including modern attempts to genetically modify the species.

Book Description
Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.
