USA HISTORY

Detailed explanation-1: -The Great Plains is the grasslands of the central United States, but precise delineation of this region has evaded agreement due to the transition between Great Plains grasslands and forests of the eastern United States.

Detailed explanation-2: -There are three kinds of grasslands on the great plains, short grass prairie, mixed grass, and long grass prairie. In each of these, grass species serve all the keystone roles. They provide food, shelter, act as larval hosts for numerous species and acted as the primary food for buffalo.

Detailed explanation-3: -Parts of 10 U.S. states lie within the Great Plains. They are Montana, North Dakota, South Dakota, Wyoming, Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico. The Great Plains also extend into Canada, into portions of Manitoba, Saskatchewan, Alberta, and the Northwest Territories.

Detailed explanation-4: -The Northern Great Plains comprises five states: Montana, Nebraska, North Dakota, South Dakota, and Wyoming. Although it is home to only about five million people, the region is an integral part of the nation’s food supply, with vast tracts of land devoted to dryland and irrigated crops and livestock grazing.
