The peat of the rut may well be 7 days prior to November 15th, but it will be due to photoperiodism, not QDM.
QDM can produce a more balanced herd(buck/doe ratio), but it cannot eliminate early breeding and late breeding, which is a major factor in a drawn out rutting period.
Well I humbly disagree because photoperiodism doesn't change from year to year. The amount of sunlight for each day is an annual constant. For example, the amount of sunlight on Oct 30th 2008 is the same as it was in 2007, 2006, 2005, etc.
So I don't see how that can be a factor.
As we regain a more healthy balance, the deer are attempting to breed earlier because competition is high. We have more older class bucks and less does and that's directly due to QDM practices in the state.
