In my neighborhood, there are gobs of white oak acorns early in the season, but they are mostly gone by the start of rifle season. The majority of my productive stands, therefore, are overlooking the other varieties. In short, the white oaks bring them in and the red oaks hold them.
What brings me a banner year is when the pin oaks are still dropping going into the 2nd weekend in November. It's happened now twice in 8 seasons, and it caused a dramatic increase in deer activity on top of my ridges both times. What seems to cause it is unseasonably warm temperatures. I remember the pin oaks dropping in mid September when I was little. If there is anything to this whole Global Warming hooplah, I'm for it. I'm going to be like Drew Carey and stand out with my can of freon.
