This wide-ranging and accessible contribution to the study of risk, ecology and environment helps us to understand the politics of ecology and the place of social theory in making sense of environmental issues. The book provides insights into the complex dynamics of change in `risk societies′.
This book examines the ecology and management of kangaroos and shows how they interact with their own environment and with that shaped by sheep grazing and the wool industry. It presents the results of intensive and detailed studies of feeding behaviour, movement and habitat utilisation, body condition and population dynamics, weather and plant growth.
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.

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.
In this how-to guide, ecologist and forest farmer Steve Gabriel explores the philosophy and techniques behind silvopasture - the integration of trees, animals, and forages in a whole-system approach that creates a number of benefits for livestock, farmers, and the environment. This system not only provides a sustainable farm income, but also holds the key to restoring land, building soil carbon, and creating climate resilience.--COVER.
Dreaming of Sheep in Navajo Country offers a fresh interpretation of the history of Navajo (Diné) pastoralism. The dramatic reduction of livestock on the Navajo Reservation in the 1930s -- when hundreds of thousands of sheep, goats, and horses were killed -- was an ambitious attempt by the federal government to eliminate overgrazing on an arid landscape and to better the lives of the people who lived there. Instead, the policy was a disaster, resulting in the loss of livelihood for Navajos -- especially women, the primary owners and tenders of the animals -- without significant improvement of the grazing lands. Livestock on the reservation increased exponentially after the late 1860s as more and more people and animals, hemmed in on all sides by Anglo and Hispanic ranchers, tried to feed themselves on an increasingly barren landscape. At the beginning of the twentieth century, grazing lands were showing signs of distress. As soil conditions worsened, weeds unpalatable for livestock pushed out nutritious native grasses, until by the 1930s federal officials believed conditions had reached a critical point. Well-intentioned New Dealers made serious errors in anticipating the human and environmental consequences of removing or killing tens of thousands of animals. Environmental historian Marsha Weisiger examines the factors that led to the poor condition of the range and explains how the Bureau of Indian Affairs, the Navajos, and climate change contributed to it. Using archival sources and oral accounts, she describes the importance of land and stock animals in Navajo culture. By positioning women at the center of the story, she demonstrates the place they hold as significant actors in Native American and environmental history. Dreaming of Sheep in Navajo Country is a compelling and important story that looks at the people and conditions that contributed to a botched policy whose legacy is still felt by the Navajos and their lands today.
Grazing management might seem simple: just put livestock in a pasture and let them eat their fill. However, as Sarah Flack explains in The Art and Science of Grazing, the pasture/livestock relationship is incredibly complex. If a farmer doesn't pay close attention to how the animals are grazing, the resulting poorly managed grazing system can be harmful to the health of the livestock, pasture plants, and soils. Well-managed pastures can instead create healthier animals, a diverse and resilient pasture ecosystem, and other benefits. Flack delves deeply below the surface of "let the cows eat grass," demonstrating that grazing management is a sophisticated science that requires mastery of plant and animal physiology, animal behavior, and ecology. She also shows readers that applying grazing management science on a working farm is an art form that calls on grass farmers to be careful observers, excellent planners and record-keepers, skillful interpreters of their observations, and creative troubleshooters. The Art and Science of Grazing will allow farmers to gain a solid understanding of the key principles of grazing management so they can both design and manage successful grazing systems. The book's unique approach presents information first from the perspective of pasture plants, and then from the livestock perspective--helping farmers understand both plant and animal needs before setting up a grazing system. This book is an essential guide for ruminant farmers who want to be able to create grazing systems that meet the needs of their livestock, pasture plants, soils, and the larger ecosystem. The book discusses all the practical details that are critical for sustained success: how to set up a new system or improve existing systems; acreage calculations; paddock layout; fence and drinking water access; lanes and other grazing infrastructure; managing livestock movement and flow; soil fertility; seeding and reseeding pastures; and more. The author includes descriptions of real grazing systems working well on dairy, beef, goat, and sheep farms in different regions of North America. The book covers pasture requirements specific to organic farming, but will be of use to both organic and non-organic farms.
This text presents edited key papers from the International Symposium on Grassland Ecophyisiology and Grazing Ecology held in Curitiba, Brazil in August 1999. It considers how plants within grasslands respond to and are adapted to grazing animals.
