The American bison roamed Northern America in great herds years before America was even founded. They were almost hunted to extinction because of the fur trade and commercial hunting. Recent recovery efforts have helped the numbers grow so there are roughly 31,000 in national parks and reserves today. The American bison is the national mammal of the United States.
