Quick Answer: When Did Wolves Go Extinct In Yellowstone?

Why did wolves go extinct in Yellowstone?

Much of the wolves’ prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range.
