CULLING DEER TO
SAVE
THE
HERD
BY
W
COURTNEY
HILE THE CONCEPT of culling
deer to save deer might seem illogical, if conducted quickly and effectively, it
can lower the probability of Chronic Wasting Disease (CWD) becoming established
in new areas.
There are two primary reasons for this.
First, reducing deer numbers in an area
where CWD exists, reduces the probability of deer encountering one another, and
as a result, reduces disease transmission.
In addition, reducing deer populations in
CWD areas helps to minimize the number
of infectious CWD prions in the environment, limiting the exposure to prions for
remaining deer.
Healthy deer can encounter the prions
either directly from other deer, or indirectly from the environment after the
prions are shed by sick deer through urine,
feces or saliva.
Since reducing deer populations will

not remove prions already in the environment, targeted removals are most effective
if conducted quickly after the detection of
a new CWD-positive.
MANAGING CWD
Since CWD first was identified in
1967, the disease - which always is fatal
to the deer and elk it infects - has spread
to 26 states and three Canadian provinces.
Management strategies in each state
vary, and each state uses hunter harvest
as part of its disease management. But
culling has been the only strategy shown
to slow the spread of CWD.
Illinois first detected CWD in 2002 and
actively began culling deer the following
year. Through culling, Illinois has been
able to hold CWD at bay, maintaining a
low CWD prevalence - about 2 percent
- ever since.
Wisconsin also detected CWD in 2002
