Photographer Tim Palmer presents hundreds of images of the U.S.'s rivers and discusses their protection and the life within them.

Rivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. - Provides a single source of information on North America's major rivers - Features authoritative information on more than 200 rivers from regional specialists - Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system - Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.

From the cliffs of Big Sur to the dunes at Cape Hatteras, from the bogs of the Boundary Waters to the deserts of the Rio Grande, the landscape of America has shaped us into the people we are. Not only is it central to ecological health and essential to the economy, it has helped form our culture and serves as a basis of national pride. The heart of America lies in the rock and soil, the mountains and the plains that surround us.In this illuminating portrait of America at the threshold of the new millennium, author Tim Palmer explores and assesses the landscape of the United States -- both timeless wonders of natural beauty and lost places scarred by human exploitation. He takes the reader on an informative and inspirational tour of our most vital landscapes, including mountains, forests, grasslands, deserts, rivers, lakes, wetlands, and seashores. He introduces us to the basic geography and ecological value of each landscape, describes historical patterns of land use, considers the most serious threats, and discusses what is being done to protect the landscape for future generations. Throughout, he instills a deeper understanding of the importance of the land, a sense of outrage at the damage that has been done, and a feeling of hope that those working to correct past abuses will succeed.Weaving together geographical, historical, and ecological information and insights, Palmer draws on thirty years of professional experience as a writer, photographer, conservationist, planner, landscape architect, and veteran traveler to present a fresh look at the past, present, and future of our land.Resounding in its account of these landscapes, compelling in the force of its information and the hope of its timely message, The Heart of America offers a fascinating measure of the land around us and a unique look at the place we call home.
