This amazing video describes how the wolves brought balance back to the environment…they actually changed a river!

 

In 1995, 14 gray wolves were released into Yellowstone National park amid 15 years of controversy called the Wolf Wars.  Today, that release has been considered a major success.

In the late 1800’s farmers and ranchers expanded into the range of wolves.  As the buffalo, the primary food source, were killed off, the wolves began to prey upon the domestic herds.  Tradition for the time period was to eliminate species that endangered livestock or human life.  By 1924 the last living gray wolves in Yellowstone had been eliminated.

Over the next 10 years, elk herds grew exponentially.  Park officials instituted a management program that consisted of culling herds by relocation and hunting by the public and officially by park rangers.  Over the next 40 years, the ecosystem became unbalanced.  Coyotes had no competition from wolves.  As populations of small animals and rodents became smaller, other small carnivores such as foxes and birds of prey began to shrink.  During this time though, the country began to understand land management and the critical balance of our ecosystems.

In 1973, the United States passed the Endangered Species Act which not only protected endangered species but also the environment in which they lived.  The planning of the reintroduction of the Rocky Mountain gray wolf began in 1980 with the creation of the Rocky Mountain Recovery Team.  When the first report was released in 1980 it was the beginning of the 15 year Wolf Wars.
