[12] In 2006, plains bison from Elk Island National Park in Alberta were released into Saskatchewan's 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]
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.
The bison coexisted with elk, deer, pronghorn, swift fox, black-footed ferrets, black-tailed prairie dogs, white-tailed jackrabbits, bears, wolves, coyotes, and cougars.
