Tall Grass Prairie Research Paper

The tall grass prairie is an ecosystem native to central North America, with fire as its primary periodic disturbance. In the past, tall grass prairies covered a large portion of the American Midwest, just east of the Great Plains, and portions of the Canadian Prairies. They flourished in areas with rich loess soils and moderate rainfall of around 30 to 35 inches per year. To the east were the fire-maintained eastern savannas. In the northeast, where fire was infrequent and periodic wind throw represented the main source of disturbance, beech-maple forests dominated.

Once this prairie covered approximately 140 million acres; now only isolated remnants exist. (Heat-Moon 261). The homesteaders saw it as a nuisance to be replaced as soon
"The increase in plant diversity we see at Konza Prairie after bison are re-introduced can be related to increases with bison grazing activities." (KSU 1). The bison that once roamed these prairies numbered close to 30 million, once settlers began to encroach on the area, and began to use the land for homesteading and agriculture the numbers dipped to nearly 500 individuals. As the bison left, the domestic cattle moved in with the homesteaders, once again disrupting the natural biodiversity of the land. In addition to the loss of the bison, fire on the prairie was a key element as well.(White 88). Typically, prairie fires were naturally occurring due to lightening strikes, and were in fact beneficial. As people began to settle and live in these areas these fires were seen as a hindrance, and were extinguished as quickly as possible. (Savage 124-26). These actions were not favorable for the grasses as these fires typically helped the natural species regenerate and helped to keep trees at bay as well. As time went on, the more human interaction that took place, the more it was destroying the natural tall grass prairie as it once
