We seek to balance the herd with the available habitat, and balance the buck age structure.
Which only works on a local, micro level.
The problems occur when some want to take 1 or 2 facets of true QDM, apply them statewide on a mandatory level, and call it QDM and claim it's only for herd health they advocate it.
Hunters benefit immensly from QDM. The main way hunters benefit is through the incresead likelihood of encountering a mature buck (4.5+).
While encountering a true mature buck is truly exciting and special, it is only a benefit to a hunter if that is their goal. And if you mandate limitations on all else that brings them to the woods, there is no benefit at all to many.
