Problem: The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot.

Conservation efforts have allowed the population to increase, but the bison remains near-threatened.
What did large herds of bison attract?
