It could be, whitetails are easily pushed. Up here many areas hold moose, elk, deer, bear, etc with no issues. That saidI have seen mule deer move into a former whitetail haven and the whitie's vamoosh for a period. The good thing is they do adapt!In time, if the moose have caused the deer to pick new ground some what you'll find them come back if the area holds what they want/need.
