Wolves Were Reintroduced To Yellowstone In 1995 And The Impact They've Had Is Unbelievable
The events that have occurred in Yellowstone National Park over the last 20+ years are nothing short of miraculous. Even though as humans we tend to think that we are the only ones who are capable of saving the environment. The truth is, if we would stop destroying it, eventually Mother Nature would take care of and restore itself in ways we would never be able to replicate.
Back in 1995, a small group of wolves was reintroduced to Yellowstone.
The park hadn't had a wolf population for nearly 70 years, which resulted in increased deer populations and decreased vegetation from their grazing.
The reintroduction of the wolf not only had a surprisingly quick impact on deer numbers, but it also ended up being a textbook example of an ecological process called "trophic cascade."
Trophic cascade is a process that starts at the top of a food chain and works its way to the bottom of it. So, even though as predators wolves survive by taking life, they also have the ability to create it.
