I will try to keep this brief and vaguely understandable.
Pennsylvania is going through now what we went through in NJ about 25 years ago.
When NJ started becoming more liberal with the number of deer, especiallly does, that you could take in one season and increased the number of days you could hunt them, the old schoolers lost their minds.
I think Wisbang is old enough to remember gun clubs in NJ banding together and applying for doe permits and then burning them.
Well the biology behind keeping doe numbers low appears to work and there has never been more deer in NJ than there is now.
I have my grandfather's NJ hunting licenses and game laws from 1910 up through the early 1920's and the deer season was 4 Wednesdays and the limit was one deer.
Pennsylvania, still to this day, allows only one buck per year (no matter what you took it with) and only recently allowed doe hunting during their rifle season. They recently added an antlerless only early muzzleloader season in October 3 years ago.
They have also added antler restrictions (3 points or better to one side) to encourage more mature breeding deer.
This has reduced the kill during their most popular 2 weeks of rifle season and is one of the reasons the complaints about the lack of deer are proliferating.
The long time PA. hunters think that allowing the extra doe kills will decimate the populations.
The outgoing head of the PA. game Commission Gary Alt is blamed for bringing in all of the new "science" and contributing to the decline in deer numbers.
I have a friend in Lycoming County who believes Alt is the Antichrist.
There is a whole big picture out there that has to be analyzed objectively and there is no doubt deer numbers are down in some of the ecologically stagnant forested areas where there is limited food sources.
Where I hunt it is always tough. No agricultural areas, no people and hundreds of square miles of mature maple, black cherry and a few oak.
In other areas of Pa., deer numbers are way up but most Pa. hunters, including me, don't change there hunting area beyond the limits of their camps that have been established for generations.
There is a great article in this month's Pennsylvania Game News that speaks to this whole issue.
With Alt gone you may see some regressive changes this year.
To summarize: The deer aren't gone, give the "new science" a chance and if you really need to kill a deer, change your location within Pa. or come to NJ.
