Oh Deer!

4. Without predators, the population will increase wildly

Their natural predators would be wolves, cougars, and coyotes. Their natural defense against predators is to reproduce, if there are none, they will severely damage the ecosystem by overgrazing. There is a well documented case of this in an area of northern Arizona.

Without natural predators or hunters, things get very bad. Massive starvation and disease are common. I’ve seen what happens when a herd of deer are trapped in a stand of trees by a blizzard,they eat all the grass,then the tree branches, then the bark, then they starve to death, after having killed the trees. It is a terrible thing to come across.

Invasive species cause problems.
