Because there were too many deer, they were thinning the forest. When the wolves were released into Yellow Stone they began killing the deer, because of this the deer’s behavior began to change cause them to avoid certain parts of the forest. Life began to flourish, the trees begun growing and because of this the birds returned as well as the beavers.
