Jelaskan Wolves dari Taman Negara Yellowstone dalam bahasa melayu

Starting in 1914, the U.S. Congress gave funds for the purposes of "destroying wolves, prairie dogs, and other animals injurious to agriculture and animal husbandry" on public lands. After the wolves were gone from Yellowstone, the coyote became the park's top canine predator. However, the coyote cannot bring down large animals. The result was a great increase in lame and sick megafauna.

By the 1990s, the Federal government had reversed its views on wolves. In a controversial decision by the U.S. Fish and Wildlife Service, wolves, imported from Canada, were reintroduced into the park. A survey conducted in 2005 showed there were 13 wolf packs, totaling 118 individuals in Yellowstone and 326 in the whole ecosystem.

The recovery of populations throughout the states of Wyoming, Montana and Idaho has been so successful that they are no longer on the endangered species list.
