ronp,
I was speaking specifically about SC, since that's wehre most of my hunting takes place nowadays.
The severe winter I'm talking about is really unrelated to snow since we rarely get that, although we had a really unbelievable 5 or 6 inch snow event last March 25th!
What I'm talking about is this-
Historically, our winter is about 4 weeks long- and we'd have maybe 5 days of sub 32 degree weather that would be a single day, then followed by three to four days or more of over 50 degree weather, and very little rain. So we tend to have an 11 month growing season, so food is almost always available to deer.
Our deer are much smaller in stature,80-90 lb live weight does are the norm, they have shorter hair, and are unused to living in a place that now has a 2 month or longer winter where temps are staying sub 20 degrees for several days in a row- having 5-6 inches of snow at the end of March, and two ten inch rains within a 10 day period in 2009,with very low but not freezing temperatures. We have also, with teh exception of those two enormous rain events, been plagued by multi-year severe, record breaking droughts during the last 10 years.
We don't have agriculture....so our critters depend on wild browse and grasses in those lean months with a sprinkling of corn from feeders.
2009 we lost our entire turkey hatch due to floods of record proportions ...I don't know how much impact its really having on deer- the two multi-year droughts and all the rest, I'm just speculating, but I would say two months of almost nothing to eat alone during the time the does are carrying those fawns would tend to impact fawn production where in the absence of such tribulations in the past would have favored fawn production more?
In Georgia, where I live, I know the deer herd is down - I was a member of the GA Dept of Natural Resources Whitetail Deer Management Committee that developed a 10 year plan for herd management.
They aggressively addressed the reduction in the herd they wanted to see- our auto insurers and farmers lobbies were adamant they wanted to see the numbers reduced- 12 tags a year and lengthened seasons-( the addition of crossbows to bow season-done prior to the committee formation) are all evidence of their aggressive approach to herd reduction.
If you kill more deer, and with 10 doe tags per hunter plus cull permits etc I think that would tend to work in that direction, you're going to see less deer.
On the other hand, with the addition of QDMA style selective buck harvest in many counties, and also that being implemented on many WMA's and private property as well, the 125-170 class of buck deer have virtually exploded with more and better deer being taken year after year.
