The Bison of the Greater Yellowstone Region

By Daryl L. Hunter

The Greater Yellowstone ecosystem is the only place in the lower 48 states where an endemic population of wild bison has survived since prehistoric times. Perhaps no other animal symbolizes the American West like the American bison. In prehistoric times millions of these quintessential creatures of the plains roamed the North America from northern Canada, south into Mexico and from Atlantic to the pacific. No one knows how many bison were in America before Columbus arrived but the guesstimate is about sixty million. They were the largest community of wild animals that the world has ever known. For a good part of the 1800s bison were considered to be in limitless supply.

After the Civil War the push to settle the west was on, new army posts were established, coinciding with the westward push of the railroads. The army and railroads contracted with local men to supply buffalo meat to feed the troops and construction laborers.

Bison were hunted nearly to extinction in the late 1800’s ---------------------------> More
