The grasslands of the western plains were the core of the great bison belt. The grasslands consisted primarily of blue grama ( Bouteloua gracilis ) and buffalo grass ( Bouteloua dactyloides ). These grasses have deep and dense root structure and retain large amounts of water, making them well suited to survive dramatic environmental fluctuations.
Grasslands occur where there is insufficient rain to support trees, thus only grasses and a few shrubs can survive. 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.

A bison mother and calf grazing on the prairie. Today, cattle, pronghorn and white-tailed deer are the most abundant mammals on the shortgrass prairie. Domestic cattle were placed in the prairie and have essentially replaced the native species that used to live in the shortgrass prairie such as bison and elk.
The bison coexisted with elk, deer, pronghorn, swift fox, black-footed ferrets, black-tailed prairie dogs, white-tailed jackrabbits, bears, wolves, coyotes, and cougars. [8] [9] The bison scoring the trees with their horns kept them from taking over the open grasslands. As bison grazed, they dispersed seeds by excreting them. [7]
Once home to free-roaming herds of bison and leaping pronghorn, the Great Plains is now a shadow of its former self, embodying the story of disappearing wilderness in North American grasslands.
The heaviest wild bull for B.b.bison ever recorded weighed 1,270 kg (2,800 lb) [34] while there had been bulls estimated to be 1,400 kg (3,000 lb). [35] B.b.athabascae is significantly larger and heavier on average than B.b.bison while the number of recorded samples for the former was limited after the rediscovery of a relatively pure herd. [23]
At a population around 300 animals, they form a free herd able to wander where they please. The bison are spread throughout Prince Albert National Park's southwestern corner, as well as some crown and private land in the area. [12] In 2006, plains bison from Elk Island National Park in Alberta were released into Saskatchewan's Grasslands ...
