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.

Presents a study of the growth and changes in the grassland areas of the desert Southwest.

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.

Readers will learn about the two main types of grassland biomes, which are tropical grasslands (savannas) and temperate grasslands. The text will focus on the climate, plants, and animals that are found on grasslands around the world. Aligned to Common Core Standards and correlated to state standards.
