Book Description
"Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice age forests that existed in these areas before the climate dried and the trees vanished, and how the intensity and frequency of fire can influence the plant and animal species of the grassland.

Book Description
The mixed grass and shrub vegetation known to scientists as desert grassland is common to the basins and valleys that skirt the mountain ranges throughout southwestern North America, extending from Arizona, New Mexico and Texas down through thirteen Mexican states. This variegated ground cover is crucial to life in an arid environment. The Desert Grassland offers the most comprehensive study to date of these flora and the rich biotic communities they support. Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice-age forests that existed in these areas before the climate dried and the trees vanished and how the intensity and frequency of fire can influence the plant and animal species of the grassland. They also document how the influence of humans—from Amerindians to contemporary ranchers, public land managers, and real estate developers—has changed the relative abundance of woody and herbaceous species and how the introduction of new plants and domesticated animals to the area has also affected biodiversity. The book concludes with a review of the attempts, both failed and successful, to reestablish plants in desert grasslands affected by overgrazing, drought, and farm abandonment. Meticulously researched and copiously illustrated, The Desert Grassland is a major contribution to ecological literature. For advanced lay readers as well as students and scholars of history, geography, and ecology, it will be a standard reference work for years to come.

Book Description
More than forty percent of our country was once open prairie, grassland that extended from Missouri to Montana. Taking a critical look at this little-understood biome, award-winning journalist Richard Manning urges the reclamation of this land, showing how the grass is not only our last connection to the natural world, but also a vital link to our own prehistoric roots, our history, and our culture. Framing his book with the story of the remarkable elk, whose mysterious wanderings seem to reclaim his ancestral plains, Manning traces the expansion of America into what was then viewed as the American desert and considers our attempts over the last two hundred years to control unpredictable land through plowing, grazing, and landscaping. He introduces botanists and biologists who are restoring native grasses, literally follows the first herd of buffalo restored to the wild prairie, and even visits Ted Turner's progressive--and controversial--Montana ranch. In an exploration of the grasslands that is both sweeping and intimate, Manning shows us how we can successfully inhabit this and all landscapes.

Book Description
During the last 150 years, two species of mesquite trees in the Southwestern United States have become increasingly common in what formerly was desert grassland. These trees have spread from nearby watercourses onto relatively xeric upland areas, decreasing rangeland grass production. Management attempts to limit or reverse this spread have been largely unsuccessful. This paper reviews studies regarding mesquite natural history and management strategies, emphasizing studies published during the past decade. Mesquite possess a deep root system and are capable of fixing atmospheric N, rendering them capable of accessing resources unavailable to other plants in open rangeland. Their seeds, which remain viable for decades, have a hard exocarp and require scarification before germination. Consumption by cattle provides a means of scarification and seed dispersal, and is a major factor contributing to the spread of mesquite in open rangelands. Increases in atmospheric CO2 and winter precipitation during the past century also contribute to enhanced seed germination. Removal techniques have included herbicides, prescribed burning, grazing reduction, and mechanical removal. For increased effectiveness of these techniques, management goals must be clearly articulated; these goals include complete removal, no removal, and limited removal. Of these, limited removal appears the most feasible, using an initial herbicide application followed by periodic prescribed burning.

Book Description
This volume describes one of the most extensive grassland ecosystems and the efforts of Chinese scientists to understand it. Leading Chinese scientists attribute the decline in China's grasslands to overgrazing and excessive cultivation of marginal areas and discuss measures to limit the damage. The book gives its view on the Chinese approach to the study of grasslands and the relevance of this activity in China to global scientific concerns.
