Around the greater Pittsburgh area, they just had an interview on the news a couple weeks ago with the local Wildlife Conservation Officer about an EHD die off. Apparently, a number of deer have turned up dead around the Ohioville/Industry area (Southwest Pennsylvania). They say that it generally runs in cycles of 5 to 10 years. Several deer that have been exposed manage to survive and actually develop an immunity. However, once those deer die off (natural causes, predators, hunters, etc.) the "new crop" coming in do not have their immunity and the cycle starts all over again. All it takes is a hot, dry summer at that point. The deer have to congregate tighter and tighter at limited water sources and the midge flies that carry the disease have themselves a smorgasbord. Thankfully, the first real, good frost of the fall usually takes care of the flies and halts the disease 'til next summer. Today was opening day of PA archery white-tail season, but I'm laid up with a bum knee. So, I haven't been out to see how things are doing in person.
