The problem with QDM is that people use that for an excuse to kill does. QDM clearly states that you need to kill does if your buck to doe ratio is out of kilter but you can also accomplish this by killing fewer bucks. The only other reason is if you deer density is at or above the carrying capacity of the land. That is it no other reason. If you believe in or practice QDM and you are killing does for any other reasons you are not practicing QDM you are using it as a ploy to satisfy your needs/wants to kill does. So if you are just please don't say you are doing it for the sake of QDM because you are corrupting the minds of young hunters and causing them to kill deer for the wrong reason. Just be honest with them and tell them we are killing all theses does because we can and that is what we like to do.

Myth 2: QDM Requires Killing Numerous Does

Many QDM pioneers have been quoted as saying, �Shoot every doe you can, and then shoot three more.� Such statements were generally true when spoken, but times and situations change, and as managers we need to adapt to current conditions. In the past, many programs benefitted from aggressive antlerless deer harvests, hence the recommendation to shoot all available does. However, as deer herds are reduced, similarly aggressive harvests are less necessary or advised. In addition, predator populations are increasing in many areas of the U.S. and Canada. Expanding coyote, black bear, bobcat and wolf populations are important mortality sources, and in some cases new mortality sources, for deer herds.

The take-home message is the appropriate antlerless harvest for a property should be determined locally. The local deer density, habitat quality, mortality factors (predators, winter severity, vehicle kills, etc.) and landowner goals all impact the number of antlerless deer that can or should be harvested. These factors vary annually and thus antlerless harvest goals should also be determined on an annual basis. Based on the above factors, some QDM programs will require large antlerless harvests, some will require moderate antlerless harvests, and some will require minimal or even no antlerless harvests. It�s as incorrect to state that all QDM programs require large antlerless harvests as it is to state that all hunters hunt from a vehicle, or over a food plot, or in a swamp.
