Book Description
It is a widely held belief that a climax vegetation of closed forest systems covered the lowlands of Central and Western Europe before man intervened in prehistoric times to develop agriculture. If this intervention had not taken place, the forest would still be there, and if left the grassland vegetation and fields now present would revert to a natural closed forest state, although with a reduced number of wild species. This book, which an updated and expanded version of the author's 1997 thesis (presented to the Wageningen University, Netherlands), challenges the traditional view, using examples from history, pollen analyses and studies on the ecology of tree and shrub species such as oak and hazel. It tests the hypothesis that the climax vegetation is a closed canopy forest, against the alternative hypothesis that species composition and vegetational succession were governed by large herbivores, and that the Central and Western European lowlands were covered by a park-like landscape consisting of grasslands, scrub, solitary trees and groves bordered by a mantle and fringe vegetation. Comparative information from the eastern USA is also included throughout the book (this was not present in the thesis), because the forests there are commonly regarded as being analogous to the primeval vegetation in Europe. The book is arranged in 7 chapters: (1) General introduction and formulation of the problem; (2) Succession, the climax forest and the role of large herbivores; (3) Palynology, the forest as climax in prehistoric times and the effects of humans; (4) The use of the wilderness from the Middle Ages up to 1900; (5) Spontaneous succession in forest reserves in the lowlands of Western and Central Europe - including examples from France, Germany, Austria, Slovenia, Sweden, Poland; (6) Establishment of trees and shrubs in relation to light and grazing; and (7) Final synthesis and conclusions. Twelve appendices are included giving further information, and there are 67 pages of references and a subject index.

Book Description
In this comprehensive book, the critical components of the European landscape – forest, parkland, and other grazed landscapes with trees are addressed. The book considers the history of grazed treed landscapes, of large grazing herbivores in Europe, and the implications of the past in shaping our environment today and in the future. Debates on the types of anciently grazed landscapes in Europe, and what they tell us about past and present ecology, have been especially topical and controversial recently. This treatment brings the current discussions and the latest research to a much wider audience. The book breaks new ground in broadening the scope of wood-pasture and woodland research to address sites and ecologies that have previously been overlooked but which hold potential keys to understanding landscape dynamics. Eminent contributors, including Oliver Rackham and Frans Vera, present a text which addresses the importance of history in understanding the past landscape, and the relevance of historical ecology and landscape studies in providing a future vision.

Book Description
The New Forest in southern England is an area of mixed vegetation set aside as a Royal Hunting Forest in the eleventh century and since that time subjected to heavy grazing pressure from large herbivores. The entire structure of the Forest and its various communities has been developed under this continued history ofheavy grazing, with the estab lishment of a series of vegetational systems unique within the whole of Europe. The effects of large herbivores in the structuring of this eco system in the past, and the pressure of grazing continuing to this day, have in turn a profound influence, indeed the dominating influence, on the whole ecological functioning of the Forest system. Because of its assemblage of unique vegetation types, the area is clearly of tremendous ecological interest in its own right. In addition, its long history of heavy grazing ani the continued intense herbivore pressure make the New Forest an ideal study-site for evaluation of both short-term and long term effects of grazing upon temperate ecosystems. The N ew Forest (some 37,500 ha in total area) currently supports a population of approximately 2,500 wild deer (red, roe, sika and fallow); in addition 3,500 ponies and 2,000 domestic cattle are pastured on the Forest under Common Rights.

Book Description
Livestock grazing is the most widespread commercial use of federal public lands. The image of a herd grazing on Bureau of Land Management or U.S. Forest Service lands is so traditional that many view this use as central to the history and culture of the West. Yet the grazing program costs far more to administer than it generates in revenues, and grazing affects all other uses of public lands, causing potentially irreversible damage to native wildlife and vegetation. The Western Range Revisited proposes a landscape-level strategy for conserving native biological diversity on federal rangelands, a strategy based chiefly on removing livestock from large tracts of arid BLM lands in ten western states: Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming. Drawing from range ecology, conservation biology, law, and economics, Debra L. Donahue examines the history of federal grazing policy and the current debate on federal multiple-use, sustained-yield policies and changing priorities for our public lands. Donahue, a lawyer and wildlife biologist, uses existing laws and regulations, historical documents, economic statistics, and current scientific thinking to make a strong case for a land-management strategy that has been, until now, "unthinkable." A groundbreaking interdisciplinary work, The Western Range Revisited demonstrates that conserving biodiversity by eliminating or reducing livestock grazing makes economic sense, is ecologically expedient, and can be achieved under current law.

Book Description
The early luxury of free forage on unclaimed western public domain allowed the building of fortunes in cattle and sheep and offered opportunities to successive waves of settlement. But the western public lands could not last. The range became overgrazed, overstocked, overcrowded. Animals were lost, much range was irreversible damaged, and even violence occurred as cowmen, sheepmen, and settlers competed for the best forage. Congress intervened by designating the U.S. Forest Service as the pioneer grazing control agency. The Forest Service's controls represent not only attempts to protect a resource but also a social experiment designed to prevent the monopolization of rangelands by large outfits and to encourage small enterprises. The Forest Service has become the undisputed leader in bringing order, rationality, and economic use to the range resources under government supervision. The problems and continuing challenges of the task emerge in these pages.

Book Description
This volume investigates how large herbivores not only influence the structure and distribution of the vegetation, but also affect nutrient flows and the responses of associated fauna. The mechanisms and processes underlying the herbivores' behavior, distribution, movement and direct impact on the vegetation are discussed in detail. It is shown that an understanding of plant/animal interactions can inform the management of large herbivores to integrate production and conservation in terrestrial systems.

Book Description
Most prairies exist today as fragmented landscapes, making thoughtful and vigilant management ever more important. Intended for landowners and managers dedicated to understanding and nurturing their prairies as well as farmers, ranchers, conservationists, and all those with a strong interest in grasslands, ecologist Chris Helzer’s readable and practical manual educates prairie owners and managers about grassland ecology and gives them guidelines for keeping prairies diverse, vigorous, and viable. Chapters in the first section, "Prairie Ecology," describe prairie plants and the communities they live in, the ways in which disturbance modifies plant communities, the animal and plant inhabitants that are key to prairie survival, and the importance of diversity within plant and animal communities. Chapters in the second section, "Prairie Management," explore the adaptive management process as well as guiding principles for designing management strategies, examples of successful management systems such as fire and grazing, guidance for dealing with birds and other species that have particular habitat requirements and with the invasive species that have become the most serious threat that prairie managers have to deal with, and general techniques for prairie restoration. Following the conclusion and a forward-thinking note on climate change, eight appendixes provide more information on grazing, prescribed fire, and invasive species as well as bibliographic notes, references, and national and state organizations with expertise in prairie management. Grasslands can be found throughout much of North America, and the ideas and strategies in this book apply to most of them, particularly tallgrass and mixed-grass prairies in eastern North Dakota, eastern South Dakota, eastern Nebraska, eastern Kansas, eastern Oklahoma, northwestern Missouri, northern Illinois, northwestern Indiana, Iowa, southwestern Wisconsin, and southwestern Minnesota. By presenting all the factors that promote biological diversity and thus enhance prairie communities, then incorporating these factors into a set of clear-sighted management practices, The Ecology and Management of Prairies in the Central United States presents the tools necessary to ensure that grasslands are managed in the purposeful ways essential to the continued health and survival of prairie communities.

Book Description
The understanding and management of land resources used by grazing animals are of major importance to ecologists and agricultural and environmental scientists. This book fills a major gap in the market by synthesising a range of perspectives on grazing systems, drawn from plant science, animal science and ecology. It outlines the principles of herbage growth and competition; of animal nutrition and grazing behavior; and of the interactions of plant and animal factors that are central to an understanding of grazing systems. Chapters on the management of grazing systems cover both intensive and extensive systems (including rangelands) from all major agroecological zones of the world. The book is written by leading authorities from the USA, UK, Australia, New Zealand, South Africa, Israel and France. It represents a major contribution to the literature for advanced students and research workers concerned with plant science (especially grasslands), animal science (especially ruminants), and natural and agricultural ecosystems.

Book Description
An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.

Book Description
Forest is the natural vegetation of most of Europe. Although the majority has been destroyed by human activity over the centuries, a considerable amount remains and has been managed to varying degrees and for a wide variety of reasons. This has resulted in a large number of natural and semi-natural landscapes and habitat types over the region and a high diversity of plant and animal communities adapted to them. The growing interest in natural history and the environment in recent years has resulted in a greater demand for information on the complex ecological history of European forest. This book is unique in providing wide ranging and detailed case studies on specific aspects, including grazing, management practices and conservation and overviews, from recognized authorities, of the latest research on the ecological history of forests and woodland in Europe. It consists of selected papers given at an international conference of forest historians organized in association with the British Ecological Society and the International Union of Forest Research Organizations at Nottingham University in September 1996. Contributions come from the UK, Ireland, Scandinavia, the Low Countries, Germany, France, Spain, Italy and Turkey. This book is essential reading for ecologists, conservationists, landscape historians, foresters and geographers. It will also be of interest to advanced students in these areas.
