Seeing
hungry deer in the winter can tug at anyone's heartstrings. However,
is feeding deer helpful or hurtful to them in the long run. The best
survival strategy for deer in the winter is to have plenty of natural food
and cover. However, early and deep snow coupled with cold temperatures
can threaten their survival. In the interest of stimulating this debate,
we surveyed state wildlife agencies and others to identify both supplemental
feeding guidelines and concerns. Here is a summary of some of the information
we uncovered.
Factors
affecting feeding:
-
Alfalfa hay and pellets are the most commonly available feed for
deer, but it takes time for the animals' digestive systems to adjust to
the change in diet from their natural browse. If deer don't have enough
fat reserves to carry them through the adjustment period, they can die of
starvation with a belly full of alfalfa.
- Can
cause scours in fawns.
- Feeding
deer in heavily traveled areas can increase deer-vehicle collisions.
- High
concentrations of deer in one area can increase vulnerability to predation
of poaching.
- High
concentrations of deer can increase transmission of disease (especially
eye and respiratory infections).
- Wildlife
will continue to eat other forages even in areas where they are fed, and
the high concentration of animals will cause the range in that area to be
overused.
- When
the expense of feeding causes feeding areas to shut down, deer are left
searching for food in urban areas where they can cause damage to crops,
shrubs and trees.
- Intense
competition for food in a limited space will often cause higher death rates
for fawns than under more natural dispersed conditions.
- Starvation
primarily happens to animals that enter the winter in poor body condition,
according to careful biological studies. Deer research has shown that animals
in good condition can survive the winter on reduced feed levels. Supplemental
feeding can be virtually irrelevant to survival.
- Deer
accustomed to a feeding station will need food at least through March or
April.
- Even
the most aggressive feeding programs save only a small percentage of the
population and are very expensive.
-
There
is no substitute for healthy four-season range. Though it may seem cruel
or unkind, it is perfectly natural that 10-15 percent of deer and elk
will not survive a mild winter; more die in a harsh winter. Animals ill-equipped
to survive are taken from the herds by starvation, accidents, predators,
exposure (freezing), diseases and parasites. Feeding may save a few from
starvation but does nothing to halt losses from other causes.
What
Do You Think?
MuleDeerNet.org would like to hear from you regarding your stories and
experience, both good and bad, with supplemental feeding of mule deer
during the winter.
Should it be done at all?
If it is being done, when should it start? When should it end?
What guidelines should be followed?
Should it be regulated and if so, by whom?
Some state and provincial agencies have adopted official big game feeding
policies, while others have not.
