A Focus On Deserts And Grasslands

FACT! Australia has the worst mammal extinction rate in the world. Many of our native bird, reptile, fish and amphibian species are endangered. AUSTRALIA'S ENDANGERED ANIMALS… AND THEIR HABITATS is an exciting new series that takes a look at some of Australia's most threatened animal species and their unique habitats. Learn about: • Dozens of Australia's most vulnerable creatures • The habitats where Australia's animals live, feed and breed • Identifying characteristics that make a species vulnerable • Australian and international classification systems • Threats animals face and what is being done to save them • What YOU can do to make difference Inside each book you'll find current information, maps, statistics, fun facts, and photographs. Every book is a valuable resource designed to support Australian students and teachers, and meet Australian National Curriculum requirements.

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.

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.
