The West Coast has the Black-tailed and Mule Deer, the White-tailed Deer being mainly east of the Rocky Mountains. There are some in Montana, northern Idaho and northeastern Washington State, as well as a few localized herds, but they are the exception in the West.

We have the totally cute Black-tailed which probably would catch its hoofs on a 4 foot fence. Mule Deer have huge ears and look a bit weird. Also bigger.

You seldom hear about overpopulation of deer out west. They are watched and managed rather carefully and hunting tags issued based on management needs.
