Grand Tetons

Yellowstone and Grand Teton bison herds are prolific and multiply rapidly, range biologists say that Yellowstone can handle about 3,000 bison and Grand Teton Park can handle 600. One of the bison's few natural predators is the wolf. Wolves will usually prey on the females and calves and will rarely attack healthy bulls. It is doubtful that wolves could ever control growth of the bison herd to a level that would keep the ecosystem in balance.
