Bison naturally wander widely, far more than cattle, even under essentially open range conditions (Pinchak et. The net effect of livestock introduction into regions where bison numbers were restricted or absent is a significant loss of native biodiversity and major shifts in ecosystem function.

National parks, including four in the Great Plains, provide a major last bastion for wild bison.

They are also very similar in their grazing habits and preferences. Factors influencing, development of cryptogamic soil crusts in Utah deserts. Field review of fish, habitat improvements projects in the Grande Rhonde and John Day River basins. Morphological adaptations of the bison to facilitate existence in a grassland environment include the downward rotation of the head relative to the vertebral column, along with the lateral placement of the eye orbits which permits maintenance of visual contact with the herd as well as predator detection while grazing. In the 1830s the only whites in the Great Plains and Rocky Mountain region were the fur trappers, whose numbers even at the height of the fur trade never exceeded 1000 across the entire West. #55. 64:329-3332.

Scientists with the North Central Climate Adaptation Science Center in Colorado partnered with the tribe for a multi-year study of how the reservation's environment will change in the next century. American bison socioecology. MEDIA RESOURCES The amount of carbon in an acre of grassland versus an acre of cropland depends on soil type, topography and other factors, but based on numerous studies researchers have determined that converting grassland to cropland results in a 30 to 40 percent loss of carbon stored in the ground.
