We have gotten several properties to agree to the same rule. The tip to tip ear spread runs about 15 inches in our area, so we go with a minimum of a 15-inch spread. We are estimating that this minimum is protecting 100% of the 1.5-year old bucks and about 70% of the 2.5-year olds. We do not allow any culling. At this point, we feel that any spike or small racked buck on our property is most likely a young buck or a late born buck that will develop normally if given time.

Even though our requirement is a minimum spread of 15 inches, that does not mean that we do not have any bucks that ever make it past 15 inches. It is just a tool to give the bucks a fighting chance.

Depending on your level of management, you may choose a minimum score for bucks as some have stated. Be aware that basic QDM philosophy is to protect bucks until they reach 2.5 years of age. Going beyond this requires more investment in the property and more space. On average, you are going to lose up to 25% of the bucks due to natural mortality per year. That means that a typical QDM property will produce 1 buck in the 150 class or better (5.5-year old) per 1,000 acres per year (if managed extensively). You can increase your odds through intensive management, but that also requires more resources.

Remember that the ultimate goal of QDM to bring balance back to the deer herd. Your doe harvest is just as important as your buck harvest and will be a major factor in your success. If you are not taking does off your property, you are not practicing QDM.
