OUTDOORS FEATURE: Deer management through culling: Feasible or not?

#The deer-hunting public's
interest in deer management increases each year,as
evidenced
by countless print articles and video productions that
discuss
management-related topics. Ongoing needs
for increased doe kill, protection of young bucks, and
improved deer habitat are extensively detailed.
#Many deer hunters have grasped these concepts and
implemented them on their
hunting properties. They have improved the habitat on
their leases or landholdings
as well as the quality of their deer herds.

#Their herds are in balance with the habitat, the
buck-age structure is much improved
, and the adult buck-to-doe ratio is well balanced.
Many groups are completely satisfied
with their progress, but some hunting organizations
want to go farther.

#One of the main reasons for dissatisfaction with
a deer management program is the
size and shape of antlers on the bucks observed
and killed each year. Bucks that do
not possess what are deemed "normal" antlers
are judged inferior by many deer hunters and
managers.

#In their opinions, any buck that does not meet a
specific minimum for antler size must surely be
genetically inferior since it is subjected to the same
environmental and habitat conditions as bucks with
bigger, better-formed antlers.

#Removing these deer as "culls" to improve a
herd's
antler genetics is the logical next step in many
hunters'
and managers' minds. According to wildlife
biologist Chris
Cook, there are two important questions to
answer before
proceeding with a culling program: "Are the
problem antler
traits genetically caused?" and "Will culling
correct the
problem?" The answers to both questions
are difficult, if not
impossible, to answer in most situations.

#"Determining the cause of a free-ranging
buck's antler
'abnormality' or 'deficiency' by looking at the
live deer on
the hoof is practically impossible," Cook said.

things that carry

#Injuries, drought, and poor habitat quality
all can cause
a buck's antlers to develop abnormally. Many
of these factors
are completely out of managerial control, even
for an expert
. For these reasons, most bucks, especially
those 2 ½ years
old and younger, should as a rule be given
the benefit of the
doubt when having the quality of their antlers
judged."

#"Some types of injuries, such as those affecting
the antler pedicle,
can cause malformed antlers every year following
the injury," Cook

cases, there is
nothing genetically 'wrong' with the buck."

#Another argument against culling bucks is a lack
of understanding
about white-tailed deer genetics. By and large, the

#"What some people don't understand is that the
dam (doe) provides
as much or more genetic influence for antler
development as does the
sire," Cook explained. "If it is possible to impact a
deer herd's antler
genetics by removing specific deer, one would also
have to identify
and remove the doe that produced the cull buck

#According to Cook, most culling "experts" tend to
target bucks with
unbalanced or abnormally shaped antlers rather
than bucks with antlers
that are smaller and well formed. These bucks are
habitually labeled as
"genetically inferior" or "limited potential" bucks,
although their supposed
antler abnormalities may have absolutely nothing
to do with genetics.
On the other hand, most well formed but smaller-antlered
bucks are judged
to be young, but with good potential.

#Conversely, many of the well-formed, smaller-antlered

to be young are actually average 3 ½ years old or
older and have grown
their best antlers. Thus, deer that may actually have
a genetic abnormality
may not be culled."

#The causes of abnormal antler development in
white-tailed deer are
numerous and difficult to understand. Unfortunately,
nearly none of the
contributing factors can be identified simply by
observing free-ranging
bucks in the field.

#"In nearly all situations," Cook concluded,
"the effort expended on
trying to improve the genetics of a deer herd
would be much better
spent on practices that can return tangible
results, such as continuing
to concentrate on habitat improvement and
shooting more antlerless
deer each season."

program on your hunting property. You might
just be defeating your purpose.
