In Yellowstone National Park over the last 20+ years the events have occurred. Even though as humans we tend to think that we are the only ones who are capable of saving the environment. Its Unbelievable Wolves Were Reintroduced To Yellowstone In 1995 And The Impact They’ve Had
The increase in vegetation provided berries for the bears too, and they reinforced the impact of the wolves by hunting deer calves.
To top it all off, the wolves also had a dramatic impact on the rivers of Yellowstone. The waterways meandered and eroded less, channels narrowed, and pools formed. And because of the newly formed forests, river banks were able to stabilize themselves, which prevented premature collapsing.
Back in 1995, a small group of wolves was reintroduced to Yellowstone.
The park hadn’t had a wolf population for nearly 70 years.
When they were reintroduced to Yellowstone, the wolves began killing the deer, which not only helped with population control.
The deer began avoiding certain areas of the park — mainly valleys and gorges — which allowed the vegetation to regenerate itself.
It also caused the height of certain trees to increase, which attracted birds and beavers.
In turn, the niches and dams created by the beavers became habitats for other species, like muskrats, ducks, and fish.
The reintroduction of the wolf not only had a surprisingly quick impact on deer numbers”
So, even though as predators wolves survive by taking life, they also have the ability to create it.
Not only did the wolves hunt deer,
Also, the leftovers from the wolves became food for ravens, bald eagles, and bears, so their numbers rose!
In two decades, one species was able to not only transform the ecosystem of Yellowstone, but also its physical geography.
