I agree the map is understating the spread. However, natural predators are not long gone. Coyotes are spreading like crazy and bears are another huge deer predation species. Hunting may be limited in Massachusetts, etc. but I assure that is not true in NY or PA. In PA, schools are closed for the first day of deer season and ~500K people head off to the woods trying to find a deer.
