Common grasses were the big bluestem (Andropogon gerardii) and switch grass (Panicum virgatum). 40 States in the Southern Great Plains import over 20% of their food-related items from Arizona, and El Sandhill grasses have spreading root systems near the surface, which not only assure maximum water-gathering ability but also bind the soil and reduce erosion. term used to describe a big chunk of land in the central United States Those along that river do not generally follow its windings but cut off points of land and pursue a direct course. One fourth of Nebraska consists of the Sandhills. Fossils|Mapmaking|Medicine The first white settlers of Indiana, Illinois and Missouri also saw them, then promptly plowed them up and planted crops. The Central Great Plains are a semiarid prairie ecoregion of the central United States, part of North American Great Plains.The region runs from west-central Texas through west-central Oklahoma, central Kansas, and south-central Nebraska.. The climate of the plains is harsh, with temperatures far below freezing in the winter and harsh, hot, direct sunlight in the summer. One study of prairie plant life conducted near Lincoln, Nebraska located 237 different species of plants within one square mile of prairie. Daniel B. Botkin, Our Natural History: The Lessons of Lewis and Clark The great plains cover an area 7,74,000 km 2 (3,00,000 square miles) having west-east length of 2400 km and north- south width of 144 km.

Science of the Expedition, In the 16th century Spanish explorers first saw the vast expanse of the grasslands, calling them a "sea of grass." Some of the dunes rise to 200 feet tall. The grasses were unaffected by these fires, since they rushed quickly over the surface of the land but did not touch the roots underground. If dead vegetation builds up, it smothers the growth of new grass in the spring; this is the single greatest natural factor in stopping the growth of tallgrass. Ancient inland seas grew and waned across the continent's midsection, depositing layer upon layer of sediments. Pronghorns are the only living animals with branched horns which shed sheathes over the horns annually. (LogOut/ It is estimated that as many as 25 billion prairie dogs once inhabited the plains. Through it all run the rivers, slow, lazy rivers winding through the flat plains, shallow and muddy. The eastern boundary is harder to define because it is not as visible.

When the plows of the white farmers, the "sodbusters" broke through and destroyed this root system, the stage was set for disaster as loose soils could be blown away by the winds. For example, the bush morning glory's roots may reach down 10 feet or more, with laterals fanning out 15 to 25 feet in all directions. Comparing the seven maps that follow shows the challenge of defining the Great Plains.

Southeastern Oklahoma is home to the Ouachita Mountains, with the Wichita and Arbuckle mountain ranges in the the southern portion of the state. But unlike Africa's grasslands, where many species evolved together and continue to coexist, the grasslands of North America developed incredible populations of a single animal, the bison, with smaller numbers of elk and deer.

There is a subtlety about the geography in the Great Plains region. The neighboring Southwest region is especially vulnerable to climate change due to its rapidly increasing population, changing land use and land cover, limited water supplies, and long-term drought (Ch. Box 880214 Lincoln, NE 68588-0214. The mightiest among them is, of course, the Missouri-Mississippi system. In the historic period of the Indian occupation of the plains, before white intrusions, the prairies covered more land in what is now the United States than any other kind of vegetation - more area than the green deciduous forests of the east which spread from Maine to Georgia; more area than the deserts of the southwest; more area than the boreal forests of the north.
