Not seeing deer is not an accurate way of judging the size or health of the herd IMHO. I hunted most of October and all of November archery season here in the southern zone (4F) and saw the fewest deer I've seen in years. Last year was spectacular with a heavy acorn crop which drew deer like a magnet. In September this year they were all over the place, deer in every field as I drove home from work each day, and more than ever.
Then came October, the warmest on record I am told and they just disappeared! Remember, 50 degrees to a deer with a winter coat is way too warm, not to mention 65 or 70!. There were no rubs, no scrapes opening, none of the usual stuff in the usual places. Then came last Sunday (I think it was the 15th). The temperature was down below 30 and it was frosty! Suddenly, scrapes and chasing. Then it warmed up again and the rest of the week was a bust.
I think that nobody, including the DEC, has a way to know what we have out there. There are so many factors influencing the herd in any given year. Food sources change, the encroachment of people, and this year, the weather. There was so little shooting yesterday morning on the gun season opener that it was strange, but I don't think that reflects the numbers of deer but rather the numbers and efforts of hunters. One of my neighbors came by and showed me a truly marvelous buck he took with his rifle. He works hard at it.
Just as an aside, I do think that we have to continue to protect the early archery seasons from muzzleloaders and crossbows, on principle. That seems to be a plan the DEC has for the future. They don't think the bowhunters do a good enough job on the doe population, if that tells you anything about numbers of deer.
So... maybe this belongs in the "politics" forum?
