Large numbers of grizzly bears once roamed the praries. They were driven to near extinction by humans during the 1900s, and nothing can be done to bring them back.
In areas where people and grizzly bears share the same habitat, humans start killing the bears. Human related mortality is the greatest threat to the persistence of grizzly bears today. The recovery of the bear to the Prairies is not feasible due to a lack of habitat and an inability to mitigate threats.
