Book Description
From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.

Book Description
One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.

Book Description
Biodiversity is the extraordinary variety of life on Earth -- from genes & species to ecosystems & the valuable functions they perform. Life as we know it will not be the same if our rich biodiversity heritage is dramatically altered. And the signs indicate that this is precisely what is happening. Biodiversity is threatened, & not because of catastrophic events. The current threat to biodiversity, & thus to the tapestry of life, stems primarily from expanding human populations & increased human consumption of natural resources. Fortunately, we can take steps to protect our rich biodiversity. This report explains what biodiversity is, why it is so important, why it is threatened, & what can be done to conserve this valuable resource. Illustrations.

Book Description
In response to increasing conservation activity at the large landscape scale, leaders from the public, private, and nongovernmental sectors participated in two national landscape management policy dialogues and many other informal discussions in 2009. Convened by the Lincoln Institute of Land Policy and the Center for Natural Resources and Environmental Policy at The University of Montana, the intent of the dialogues was to synthesize what we know about large landscape conservation and to identify the most important needs as we move forward.

Book Description
A flock of Pinyon Jays arrive in a flash of blue, and leave again just as suddenly. This once mysterious bird is now the subject of over 20 years of intensive research involving over one thousand colour-marked jays by Russell Balda, John Marzluff and their colleagues and helpers. This plain blue bird has turned out to be anything but plain in its biology and behaviour. Uniquely dependent on the seeds of the Pinyon Pine for food, they have developed a number of behavioural and morphological adaptations to best utilise this resource, above all caching enough seeds each autumn to supply their needs throughout the winter and fuel their unusual habit of nesting in late winter. Fluctuations in pine-seed supply, both by season and between years, poses special problems for these birds and has led to their extremely flexible and complex social system in which learning and memory play an unusually large part. They store pine seeds and retrieve them with uncanny accuracy; they form lifelong pair bonds and nest colonially, occasionally involving younger birds to help established pairs rear the young; and they use their large vocabulary to coordinate activities within one of the largest known avian societies. This intriguing story will fascinate both the enthusiastic amateur birder and the professional alike. Packed with information, it presents Pinyon Jay biology in a readable form and places them into the wider context of studies on bird ecology and evolution. Fine illustrations by Tony Angell, with additional pictures by Caroline Bauder, complete this attractive addition to any birder's bookshelf.
