Answers
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.
The Great Plains extend from Mexico in the south through the central United States to central Canada. Many sub-regions exist within the area.
The region is home to many animals, including American bison, pronghorn, mule, and white tailed deer, and birds such as ducks, hawks, and sparrows, along with many invertebrate species.
Settlement of "America's breadbasket" led to ecological destruction. Widespread agriculture led to the near-complete extermination of the American bison in the late 1800s and the reduction of the tallgrass prairie to less than 1% of its former extent. The plains are now largely agricultural, with large ranches and farms. However, restoration efforts in some areas, like Montana's American Prairie Reserve, are leading to the gradual expansion of the threatened ecosystem.
