The effect of wolves on Yellowstone Park

[Catherine]

I knew they had introduced wolves to the Yellowstone park area. I did not realise how much of a difference they would make for the ecosystem.
This is a really interesting example of how nature can regenerate and revitalize when the natural balance is restored.

Let us hope that they cherish and protect these wolves. They have clearly brought life to the park.
