A comprehensive view of vegetation types, distribution, and the natural forces that influence plant succession in Yellowstone.
This beautifully illustrated volume on the Yellowstone Wolf Project includes an introduction by Jane Goodall and an exclusive online documentary. The reintroduction of wolves to Yellowstone National Park was one of the greatest wildlife conservation achievements of the twentieth century. Eradicated after the park was first established, these iconic carnivores returned in 1995 when the US government reversed its century-old policy of extermination. In the intervening decades, scientists have built a one-of-a-kind field study of these wolves, their behaviors, and their influence on the entire ecosystem. Yellowstone Wolves tells the incredible story of the Yellowstone Wolf Project, as told by the people behind it. This wide-ranging volume highlights what has been learned in the decades since reintroduction, as well as the unique blend of research techniques used to gain this knowledge. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, and the rippling ecosystem effects wolves have had on Yellowstone’s wild and rare landscape. Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is an informative and beautifully realized celebration of the extraordinary Yellowstone Wolf Project.
Our modern idea of what a healthy landscape looks like and how it functions is distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. Goldfarb shares the powerful story about one of the world's most influential species. He explains how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. -- adapted from jacket
Established in 1872, Yellowstone National Park is the oldest and one of the largest national parks in the world. In this remarkable book, scientists Mary Meagher and Douglas B. Houston present 100 sets of photographs that compare the Yellowstone of old with the park of today. Most of the photo sets include three pictures-not the usual two-with many of the original views dating back to the 1870s and 1880s. From the same photo points used by early photographers, Meagher and Houston rephotographed the scenes in the 1970s, and then, following the great fires of 1988, again in the 1990s. The result is an illuminating record of Yellowstone's dynamic ecosystem and its changes over time. Through close analysis of the photos and reference to the vast amount of available data, Meagher and Houston describe changes in vegetation, growth of wildlife populations, the effect of beaver occupancy on wetland areas, and geothermal and elevational shifts. At the same time they point out the extent to which many sites have not changed-despite important switches in park policy and an increase in human activity. Yellowstone National Park has long been the focus of major ecological debates. Should managers allow wildfires to burn? Should the elk and bison populations be controlled? Are too many people visiting the park? Yellowstone And The Biology Of Time offers a wealth of information to help us answer these questions. A visual treasure, this book will be of value to scientists from various disciplines as well as to the many people who care about Yellowstone and other protected wilderness areas around the world.
Chase asserts that Yellowstone is being destroyed by the very people assigned to protect it: the National Park Service. Named as one of "ten books that mattered" in the 1980s by Outside magazine and a book of continuing crucial relevance. Index; map.
Emigrant Creek cattle allotment is located 48 km northwest of Burns, Oregon. It was photo sampled at nine original sites, starting in 1975. Photos were taken three times per year: June 15 prior to cattle grazing, August 1 at pasture rotation, and October 1 at the end of grazing. An additional four photopoints were established following disturbance from flooding and beavers. Results reported here cover 30 years, 1975 to 2005. Cattle did not significantly impact the riparian area. Beavers (Castor canadensis) arrived in 1984 and departed in 1994. They seriously reduced aboveground willow biomass by harvesting stems for food and dam construction. Dams raised the water table causing a dry meadow to become moist, and increased water in a wet meadow that inhibited willow growth. Beaver departure in 1994 left dams unmaintained. A 50-year flood event in February 1996 eroded dams and created a new channel. The water table was reduced below that of the 1984 levels, causing a dry meadow to revert to pre-1984 conditions and permitting willows to vigorously expand in a wet meadow. Dynamic riverine riparian environmental conditions seriously challenge the typical range management concepts of S2condition and trend. S3 There is no S2climax good condition. S3 Instead a S2state-and-transitionS3 concept seems a more apt range management concept to describe range conditions resulting from beaver dams and flooding over a 30-year period on Emigrant Creek cattle allotment.
The Beaver: Its Life and Impact is designed to satisfy the curiosity and answer the questions of anyone with an interest in these animals, from students who enjoy watching beaver ponds at nature centers to homeowners and land managers. Color and black-and-white photographs document every aspect of beaver behavior and biology, the variety of their constructions, and the habitats that depend on their presence. A second edition of The Beaver: Ecology and Behavior of a Wetland Engineer, published by Cornell University Press under its Comstock Publishing Associates imprint in 2003, this book has been revised throughout and includes a new section on population genetics and features updated data about the beaver's range in North America, reintroduction efforts in Europe, and information about the world's largest beaver dam, discovered in northern Alberta in 2010 and visible from space, as well as the most current bibliography on the subject. As this book shows, the beaver is a keystone species—their skills as foresters and engineers create and maintain ponds and wetlands that increase biodiversity, purify water, and prevent large-scale flooding. Biologists have long studied their daily and seasonal routines, family structures, and dispersal patterns. As human development encroaches into formerly wild areas, property owners and government authorities need new, nonlethal strategies for dealing with so-called nuisance beavers. At the same time, the complex behavior of beavers intrigues visitors at parks and other wildlife viewing sites because it is relatively easy to observe.
