The near extinction of the species during the 19th century unraveled fundamental ties between bison, grassland ecosystems, and indigenous peoples’ cultures and livelihoods. English speakers used the word buffalo for this animal when they arrived. [1] Bison was used as the scientific term to distinguish them from the true buffalo.
An adult European bison. Although they are superficially similar, the American and European bison exhibit a number of physical and behavioral differences. Adult American bison are slightly heavier on average because of their less rangy build and have shorter legs, which render them slightly shorter at the shoulder. [43]
The practice has proven to be beneficial in moderation in restoring and maintaining grassland and heathland ecosystems. Conservation or monitored grazing has been implemented into regenerative agriculture programs to restore soil and overall ecosystem health of current working landscapes. The optimal level of grazing and grazing animal will ...
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 ...

The destruction of the bison had serious consequences for the ecosystems of the great bison belt. The resilient short grasses were dominated by the less stable but aggressive tall grasses. Cattle soon replaced the bison as the primary consumers of the grasslands. By 1900, about 30 million livestock subsisted on the bison belt. [18]
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.
The ecosystem was maintained by a pattern of disturbance caused by natural wildfire and grazing by bison, a pattern which is called pyric herbivory. [ 3 ] Before the 1800s, bison were a keystone species for the native shortgrass prairie habitat as their grazing pressure altered the food web and landscapes in ways that improve biodiversity . [ 4 ]
