Book Description
This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km2 and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm’s plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes – brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) – an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.

Book Description
Grasslands are lands dominated by grasses, rather than large shrubs or trees. There are two main types of grasslands--tropical and temperate. Grasslands are the most widespread biome on land, covering one-fifth of the land surface. Directly or indirectly, grasses provide a very large proportion of human food--either through cultivated cereal grains such as wheat or oats, or by providing food for both wild and domestic animals that are eaten, such as deer or cattle. THE WORLD'S BIOMES series provides information on five of the most important large ecological systems in the world today: deserts, grasslands, oceans, rainforests, and wetlands. Each book in the series describes the climate, geology, vegetation, and animal life found in a particular biome, as well as the modern threats and what people can do about them. Each title in this series includes color photos throughout, and back matter including: an index and further reading lists for books and internet resources. Key Icons appear throughout the books in this series in an effort to encourage library readers to build knowledge, gain awareness, explore possibilities and expand their viewpoints through our content rich non-fiction books. Key Icons in this series are as follows: Words to Understand are shown at the front of each chapter with definitions. These words are set in boldfaced type in that chapter, so that readers are able to reference back to the definitions--building their vocabulary and enhancing their reading comprehension. Sidebars are highlighted graphics with content rich material within that allows readers to build knowledge and broaden their perspectives by weaving together additional information to provide realistic and holistic perspectives. Educational Videos are offered in chapters through the use of a QR code, that, when scanned, takes the student to an online video showing a moment in sports' history, a speech, or an instructional video. This gives the readers additional content to supplement the text. Text-Dependent Questions are placed at the end of each chapter. They challenge the reader's comprehension of the chapter they have just read, while sending the reader back to the text for more careful attention to the evidence presented there. Research Projects are provided at the end of each chapter as well and provide readers with suggestions for projects that encourage deeper research and analysis. And a Series Glossary of Key Terms is included in the back matter containing terminology used throughout the series. Words found here broaden the reader's knowledge and understanding of terms used in this field.

Book Description
"The concept of grasslands as a global resource is not new. Indeed many recognised authorities have been canvassing for a global approach to understanding, managing and exploiting this resource for many years. This is the first book that gathers together leading experts from around the world to outline our current understanding of this complex ecosystem, the ways in which it can be enhanced and utilised and where the research challenges are for the future. The following themes unite the book: - Efficient production from grassland; - Grassland and the environment; - Delivering the benefits from grassland. The reader is given an in depth understanding of the biology of the system and how grasslands are crucial for soil stabilisation and water quality. Secondly, much attention is given to how grasslands offer the possibility of increasing food supply and income generation, which is a hugely important but often ignored facet in today’s climate of extensification and biodiversity. Current advances in the grassland sciences have a proven potential to promote the economic development and environmental stability of regions, nations and peoples, particularly in some of the most resource-limited areas of the world. Approaches for achieving the most effective development and adoption of new technology are reviewed."

Book Description
This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be taken into account, notably water in all areas, and shelter in winter-cold climates. Seasonality of forage supply is a characteristic of almost all grazing lands, so the strategies for dealing with lean seasons are described. The main problems of each type are mentioned and possible strategies for their sustainable management discussed - taking into account their multiple functions, not only livestock production. The book is primarily aimed at agricultural scientists, educationalists, extensionists and decision-makers with interests in responsible use of extensive grasslands.

Book Description
Published to wide acclaim, this beautiful meditation on the fate of grassland birds has been praised for its profound wisdom and lyrical grace. Herriot, in a narrative that is at once intimate and informative, argues for the essential nature of these tiny creatures. He invites us into the unique world of dedicated scientists, passionate naturalists and such historical figures as 19th-century botanist John Macoun, the last naturalist to see the Great Plains in its pre-settlement grandeur. Grass, Sky, Song is a blending of personal experience, history, philosophy and scientific research. Filled with evocative “sidebar” descriptions of threatened birds, from the sharp-tailed grouse to the chestnutcollared longspur, this graceful book demonstrates why Trevor Herriot is regarded as one of Canada’s finest non-fiction writers.

Book Description
Forgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.
