14 Wolves Re-Introduced To A National Park Have An Unbelievable EffectAndrea Powell
Wolves are a well-known predator, but they are also necessary for a balanced ecosystem.
Yellowstone National Park is one of the largest parks in the US with over 3500 square miles of wilderness. In 1995, 14 grey wolves were released into Lamar Valley of Yellowstone National Park and Idaho, according to We Love Animals. Previous to this, wolves were almost non-existent, with the occasional exception of a lone wolf passing through.
No one imagined the positive effect that the wolves would have on the ecosystem. Within 6 short years, the park has transformed with a more balanced and healthier ecosystem, all thanks to the wolves.
Before the wolves were re-introduced, the deer population had grown immensely. Without larger predators, the deer were taking over the park, leaving most of the valleys bare of vegetation from overgrazing. When the wolves returned, the deer population declined to a more natural number. Also, the deer changed their behavior to not go to the valley where they were easier for the wolves to catch. This allowed the valleys to re-grow their vegetation.
The return of lush vegetation brought more animals back to the park. The soil and vegetation entered a healthy state, which even affected the flow of the river. Instead of the banks eroding, they held firm so the river could flow strong and fluid.
The wolves made a huge impact on other animals and the entire ecosystem. We have a lot to learn from watching how nature and animals co-exist and thrive together.
