In the last decade a trend has been sweeping the
South. More and more people are becoming interested in quality deer
management (QDM). They want the opportunity to observe and harvest mature
white-tailed deer. QDM entails managing the entire herd to produce
healthy bucks and does in accordance with existing habitat conditions.
This involves exercising restraint in harvesting young bucks and active
participation in harvesting antlerless deer (particularly adult does).
Hunters practicing QDM become managers by allowing yearling bucks to
survive to maturity, harvesting adequate numbers of does, and keeping
detailed records on deer harvested and observed. Three components are
vital for a successful QDM program: age, nutrition and genetics.
Age
Age is usually the most important
factor in producing quality deer. In many areas, more than 80 percent of
bucks harvested annually are yearlings. How can you expect the bucks on
your area to grow large when they are only 1½? As one writer put it,
“There is no such thing as a big spike, and a dead one won’t grow!” A
common response by hunters regarding QDM is: “If I let a small buck walk
by, someone else will shoot it.” That may be true, especially if the area
you hunt is relatively small (<1000 acres) or linear in shape.
Cooperation is the key. If the property you hunt is relatively small,
talk to your neighbors and encourage them to form a QDM cooperative with
adjoining properties. Many landowners have reported that when they began
harvesting larger deer, QDM became contagious and adjoining landowners
wanted to know how they could get in on the action! The old adage,
“Nothing ventured, nothing gained” certainly applies here. For every
movement away from tradition, there has to be a leader and for your area
that may be you.
Nutrition
Habitat management is an essential
part of a successful QDM program and the best way to ensure that your herd
receives optimum nutrition. The most common method used to improve
nutrition is the establishment of food plots. However, to provide any
real nutritional benefit to a deer herd, typically two to three percent of
a management area must be planted in warm- and cool-season food plots
properly distributed across the property. This strategy helps prevent
overgrazing and provides nutrition to the herd on a year-round basis,
especially during stress periods (i.e., late summer and late winter).
Other ways to increase available forage include timber stand improvement
and natural vegetation fertilization. Practices such as thinning, burning
and using selective herbicides are excellent ways to improve the quantity
and quality of vegetation utilized by deer throughout the year.
Providing adequate nutrition to
your deer herd also requires maintaining the population in balance with
its habitat. Some people believe the doe is sacred and should be spared
from harvest. This mentality was prevalent when deer numbers were low and
populations were being restocked. Harvesting antlerless deer in areas
where populations are established is not detrimental—it is necessary!
Today, hunting is the primary means of keeping populations in check and
establishing social balance within herds.

bucks (3.5+) in the harvest increased from 21 percent in 1993 to 67
percent in 1996. The percentage of fawns and yearling bucks in the
harvest dropped from 41 percent to only 5 percent. |
Concern often is expressed that
harvesting does will reduce the number of bucks in an area. This is
primarily a function of habitat quality and deer density. Depending on
the relationship of the population with the carrying capacity, an “optimum
sustained yield” can be achieved. Healthy adult does normally produce two
fawns per year. A doe in poor physical condition will have only one fawn,
if she gives birth to any at all. When the population is reduced on areas
where the carrying capacity has been reached, more nutritious forage is
available; thus most does are able to carry two fawns. Since fawns are
born at approximately a 1:1 sex ratio, more bucks may be born each year.
This can result in more bucks to hunt on your property.
Deer density affects the number of
bucks on a property in other ways as well. As the number of female deer
with established home ranges on a property increases, the number of areas
open for bucks to establish home ranges decreases. In other words, with
too many does, there is no room left for bucks. Displaced bucks typically
set up home ranges on nearby areas with lower deer densities—perhaps on
your neighbor’s property!
Genetics
Genetic traits are determined by both sexes, not just
the bucks. Factors influencing genetic quality are complex. Studies have
shown that most yearling bucks with small antlers are able to produce
quality antlers at maturity, and these “inferior” bucks are the result of
overpopulation rather than genetics. When yearling bucks comprise the
majority of the harvest, the buck age structure is most vigorous bucks as
nature intended.
Putting it all together
A key goal of QDM is to establish
and maintain the sex ratio as close to 1:1 as possible. This mimics a
population limited by natural predation and results in a greater
percentage of does being bred during their first estrous or breeding
cycle, which can bring about a shortened, more intensive rut.In many areas
traditional hunting practices (i.e., buck-only or a limited doe harvest)
have resulted in deer populations heavily skewed in favor of females.In
such populations, many does are not bred during their first estrous cycle
which results in a prolonged breeding season and, consequently, a
prolonged fawning season.These late-born fawns are handicapped by poor
quality nutrition during late summer and a shorter period for growth
before winter.

QDM not only promotes a
well-balanced, healthy deer herd, for many hunters it ensures a quality
hunting experience. The ability to hunt a deer herd with a well-balanced
adult sex ratio and good numbers of mature bucks is an exciting and unique
experience—one that is being realized by an increasing number of hunters
and landowners. However, QDM is not for everyone. Some hunters are more
interested in deer quantity than deer quality. But for those who desire an
opportunity to become a deer manager and to hunt mature bucks, QDM should
be considered.
QDM
at work: The Fairchild Creek Cooperative
Located in southwestern
Mississippi, the Fairchild Creek Cooperative was initiated in 1992 by a
dedicated group of local sportsmen. After seeking assistance from the
Mississippi Department of Wildlife and Fisheries, Deer Management
Assistance Program (DMAP) and collecting deer harvest data for one year,
the group contacted adjoining landowners and formed a cooperative.
After a couple of years, the data
began to reveal some positive trends (Figures 1 and 2). Herd health,
reproduction and recruitment were excellent and older bucks began showing
up in the harvest with increasing regularity. Through commitment and hard
work, the members of this cooperative attained their goal of creating a
quality hunting experience. Mature bucks are present now in huntable
numbers, which makes it even easier for hunters to pass young bucks. Big
rubs and scrapes have become commonplace and hunters have noticed
increased rutting activity. Some courtship chases witnessed by hunters
have involved as many as five bucks in pursuit of one doe. As you might
expect, each hunting season results in a large number of bucks being taken
to the taxidermist. Although this is not a paradise, deer hunting for
the members of the Fairchild Creek Cooperative has truly become a quality
hunting experience.

The percentage of mature bucks
(3.5+) in the harvest increased from 21 percent in 1993 to 67
percent in 1996. The percentage of fawns and yearling bucks in the
harvest dropped from 41 percent to only 5 percent. |
In 1993, the group harvested only
0.9 mature bucks per square mile. By 1996, that number had
increased to 3.3 mature bucks per square mile. |
How did they make it happen?
Making a QDM program work does not happen overnight.
It requires diligence and determination. In addition, it is essential to
work with others successfully. Suggesting a new idea to people who have
deeply ingrained opinions can be frustrating and demands persistence and a
considerate attitude toward those who do not share your opinion initially.
Two additional clubs joined the Fairchild Creek
Cooperative during the 1993-94 hunting season, thus increasing their area
for collecting harvest data to over 4,000 acres. Prior to the 1994-95
season, neighboring landowners were invited to attend a meeting. Since
1992 this dedicated group had gradually established friendships with
neighboring property owners through repeated visits and discussions
concerning QDM. So by the time the meeting was held, a positive
relationship had been established and meeting attendance was good. To
further encourage attendance, club members telephoned their neighbors
after mailing invitations to make the invitation more personal. During
the meeting, landowners were informed that participation in the
cooperative was voluntary; however, there were a few guidelines that
member clubs must follow if they wished to participate.
It was explained that any club
wishing to participate in the cooperative must follow a few basic rules.
Rule one was to collect deer harvest data under the DMAP program. Rule
two was to establish some type of club policy ensuring compliance with the
data collection program. Note that the only “rules” were to collect and
submit data.
Once this was accomplished, each club was encouraged to
adopt QDM guidelines which included: (1) shooting more does than bucks,
and (2) restricting buck harvest to those bucks that had at least one
antler 15 inches long. In this particular area, the 15-inch guideline
would eliminate 90 percent of the yearling bucks from harvest. Methods
used in other areas to restrict harvest of young bucks include antler
spread restrictions (e.g., 15 or 16-inch outside spread) and antler point
restrictions (e.g., 6 or 8-point rule).
Next, a goal was established to
maintain the percentage of yearling bucks in the harvest below 20
percent. Buck fawns then were added to this category. This was necessary
to account for buck fawns mistakenly shot as does and to allow a few bucks
to be taken by young or inexperienced hunters. New hunters were allowed
to harvest a “first buck” before being bound by the tighter restrictions.
However, many of these hunters chose not to shoot a small buck even when
allowed to do so.
Following the meeting, more
properties joined the cooperative, and during 1995 harvest data were
collected on nearly 7,000 acres. By 1996 the group had expanded to 9,000
acres. Obviously, the Fairchild Creek Cooperative is a model for others
to follow. This QDM success story was accomplished by average hunters in
an average situation. If you desire the opportunity to observe and hunt
mature white-tailed deer, give QDM a try. A little cooperation can go a
long way!
