What you’re actually talking about happened in the 1920s on the Kaibab plateau.

It’s the classic example of human interference in a biological niche that resulted in exactly the opposite of what was intended.

One of my parent's neighbors in the 1970’s was contracted to capture as many Puma's as he could at the Grand Canyon. He was one of several trapper/hunters doing this. It lasted about two years. I can remember visiting the folks and then going down to his dairy (his real job) and seeing the cats in their heavy cages. At one visit he had three. They were transplanted around the Rockies. I do know that it really upset the predator/prey balance for a while.
