<P> Bison hunting (hunting of the American bison, also commonly known as the American buffalo) was an activity fundamental to the economy and society of the Plains Indians peoples who inhabited the vast grasslands on the Interior Plains of North America, prior to the animal's near - extinction in the late nineteenth century . Even a number of Indians west of the continental divide crossed the Rocky Mountains in traditional tribal hunts on the Northern Great Plains . The species' dramatic decline was the result of habitat loss due to the expansion of ranching and farming in western North America, industrial - scale hunting practiced by non-indigenous hunters, increased indigenous hunting pressure due to non-indigenous demand for bison hides and meat, and even cases of deliberate policy by settler governments to destroy the food source of the native Indian peoples during times of conflict . Bison have always been hunted for their meat and the coats . Part of quality conservation is thinning out in certain areas . This helps in the overall health and wellness of the herds . When the forest service has to come in and capture and / or kill the bison it is always utilized to help the herd and is often given to the Native Americans in the area to help feed them . </P> <P> The steppe bison (Bison priscus) was found in North America more than a million years ago, well before the first humans are believed to have arrived . It is believed to have evolved into the giant Ice Age bison (Bison latifrons) which lived from 200,000 years ago to 30,000 years ago . It was in turn replaced by Bison occidentalis, which is believed to have come from Eurasia, and Bison antiquus which evolved separately from B. priscus . The first human arrivals in North America, the Paleo - Indians, are believed to have hunted these last two species (occidentalis and antiquus), but did not rely on them to the exclusion of other large herbavorous mammals such as mammoths, mastodons, camels, horses, and ground sloths . Around 11,000 - 10,000 years ago, however, the majority of the large game species in North America became extinct, possibly due to climate change, overhunting, or some combination of these and other factors . One of the few large survivors was B. antiquus, but its average size declined until it evolved into the smaller modern American bison around 5,000 years ago . </P>
