The Amazing Impact of 14 Wolves Released in Yellowstone Over 20 Years Ago

Wolves were once a mainstay in the Yellowstone National Park, the first national park in the United States and one of the first ever in the world. However, by 1926 their population in the region had gone extinct, leaving the park wolf-less for almost seven decades.

By 1995, a joint effort between the US Fish and Wildlife Service and Canadian biologists saw wolves released into Yellowstone for the first time since their disappearance, with 14 wolves relocated from Canada to the national park.

As was expected, the population of wolves in the area slowly increased, but there were other changes to Yellowstone that were not as expected. In fact, the difference made by the original 14 wolves is nothing short of staggering, as they have had a huge impact on the park’s ecosystem.
Take a look at the video below explaining the incredible changes that have taken place since wolves were reintroduced into Yellowstone National Park.
