The ecology of the Great Plains is diverse, largely owing to their great size. Differences in rainfall, elevation, and latitude create a variety of habitats including short grass, mixed grass, and tall-grass prairies, and riparian ecosystems. [1] The Great Plains extend from Mexico in the south through the central United States to central ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

The Great Plains smallpox epidemic of 1837 spanned thousands of miles, reaching California, the Pacific Northwest coast, and central Alaska before finally subsiding in 1840. [12] The epidemic is estimated to have killed more than 17,000 people along the Missouri River alone. [ 2 ]
The Central Great Plains are a 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. It is designated as the Central and Southern Mixed Grasslands ecoregion by the World Wide Fund for Nature.
The shortgrass prairie is an ecosystem located in the Great Plains of North America.The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula).
The High Plains ecology region is designated by 25 on this map. Childress County, Texas, June 1938.. The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains.
Among the Hidatsa, typical of Great Plains farmers, fields were cleared by burning which also fertilized the soil. The three implements used by Indian farmers were the digging stick, hoe, and rake. The digging stick was a sharpened and fire-hardened stick, three or more feet long, that was used to loosen soil, uproot weeds, and make planting holes.
Prairie madness was caused by the isolation and tough living conditions on the prairie. The level of isolation depended on the topography and geography of the region. Most examples of prairie madness come from the Great Plains region. One explanation for these high levels of isolation was the Homestead Act of 1862. This act stipulated that a ...
