FACTS ON BAITING
Disease
1
In Michigan, where bovine TB exists in wild deer, scientists believe
that the maintenance of bovine TB in white-tailed deer is directly related to
supplemental feeding/baiting and the increased focal densities these
practices create. Inhalation of bovine TB bacteria or consumption of feed
contaminated with the bacteria from deer coughing and exhalation is much more
likely to occur.
2
Chronic Wasting Disease (CWD) has been observed in free-ranging deer
and elk in Colorado and Wyoming. Evidence suggests infected deer and elk
probably transmit the disease through animal-to-animal contact and/or
contamination of food or water sources with saliva, urine and/or feces. This
disease has not been reported in the Southeast, however, due to its spread in
the western U.S., it remains a potential problem.
3
A study in Texas revealed that 44% of the deer corn sold for baiting
purposes tested positive for excessive levels of aflatoxin, a harmful
biological toxin from a fungus which can pose a deadly threat to wildlife,
especially avian species (e.g. wild turkeys, quail, and songbirds).
4
In 1993, a Southeastern Cooperative Wildlife Disease Study (SCWDS)
survey of bait piles in North and South Carolina revealed that over 50% of the
bait piles tested contained excessive levels of aflatoxin.
5
In Georgia in 1997, samples were taken from corn sold as wildlife feed
and analyzed for aflatoxins. Ten (10%) of the samples tested positive for
aflatoxins.
6
Other diseases of concern in North America are anthrax, blackleg,
brucellosis, hemorrhagic disease, vesicular stomatitis, leptospirosis,
listeriosis, demodectic mange, tularemia, anaplasmosis and brainworm.
7
Although it is difficult to attribute the spread of disease to deer
density alone, it is true that some disease problems occur more commonly in
areas of high density such as would occur around baited areas.
8
Animals are attracted to artificial feed in higher densities than would
otherwise naturally occur. This attraction to such feed results in more
frequent contact among individuals, thereby facilitating the opportunity for
disease transmission among individuals.
9
Ruminants, such as deer, that are exposed to concentrated grain diet
(e.g. corn) can suffer from grain overload or lactic acidosis. Lactic
acidosis can kill them. In Saskatchewan from 1995-2001, 50% of deer submitted
each year to the Canadian Wildlife Health Centre were diagnosed as dying from
grain overload. Given the small likelihood of finding wild deer that are
either dying or recently died from grain overload, it is likely that a number
of wild deer that succumb to this disease go undetected.
10
In Maine, white-tailed deer at feeding stations have suffered from
outbreaks of demodectic mange caused by the spread of mites while at feeding
stations.
Deer Movement Patterns
Another behavioral change in deer frequently
attributed to deer baiting is increased nocturnal activity.
1
A Mississippi study noted that 90% of bucks’ use of bait stations was
during non-legal shooting hours. Over 84% of total use occurred during the
hours of darkness.
2
Normal diurnal: nocturnal movement ratios averaged 2.22 for bucks and
2.03 for does in a Georgia study.
3
A Texas study of baited and non-baited stands showed that deer use of
baited stands became more nocturnal as the hunting season progressed.
4
A Michigan study documented that most feeding at bait stations occurred
at night and daytime feeding was non-existent.
Habitat and Ecological Impacts
Deer baiting affects surrounding habitats and can
cause ecological damage that affects a wide variety of wildlife dependent on
those habitats.
1
In Michigan, changes in tree species composition, retarded forest
regeneration, and delayed development of stands have resulted from the
increased density of deer near bait stations because the deer continue to feed
on natural browse.
2
In Wyoming, moose suffered a reduction in the carrying capacity of
their habitat because elk maintained on artificial feed had reduced the amount
of willow trees in the area.
3
A study investigated the effects on the structure of an eastern
deciduous forest from 27 years of artificial feeding of ungulates, including
deer. Populations of deer, elk and sheep were maintained at higher densities
in feeding areas than in areas where feeding did not occur. In the areas
where feeding occurred, understory vegetation was decreased, little ground
cover existed and forest regeneration was hampered. Ground nesting birds,
including wild turkeys were less abundant in the feeding areas.
4
Providing supplemental feed or bait may negatively impact populations
of wild turkeys and other ground nesting birds by concentrating potential nest
predators, such as raccoons and opossums, near feeders. Consequently the
population of predators near the feeding sites increases.
5
Concentrating deer near bait sites causes overbrowsing of beneficial,
high-quality native plant species and increases the presence of less
desirable, low-quality plant species within the vicinity (< 1 mile
radius) of bait sites.
Baiting and Hunter Success
1
A 1999 Michigan phone survey revealed 44% of deer hunters were
successful using bait while 52% were successful without bait.
2
A 1984 Michigan survey found hunters using bait were no more effective
in harvesting deer (2.4 deer per 100 hunter days) than those who did not use
bait (2.2 deer per 100 hunter days).
3
A 1993 Wisconsin survey showed that hunting with bait does not increase
a hunter’s success rate. In the survey, 50% of hunters who used bait during
the 1992 gun hunts bagged a deer while 54% not using bait bagged a deer.
4
In a Texas study, 77% of bucks harvested from baited stands were
yearlings. Most deer harvested at bait sites are yearlings; older, mature
bucks are less likely to be seen near bait sites during the daylight hours.
5
In South Carolina, hunters in the low country, where baiting occurs,
are less successful than hunters in the upstate, where baiting is illegal.
Hunters in the upstate harvested 15.4 deer per square mile whereas hunters in
the low country harvested 11.0 deer per square mile, though hunters in the low
country average 30% more time afield.
Social, Ethics, Perception Issues
1
A 2004 survey of Georgia residents, landowners and hunters showed
opposition to legalizing the hunting of deer over bait among all groups.
Among the general population 59% opposed baiting and 29% supported. Among
landowners, 54% opposed baiting and 34% supported baiting. Among hunters, 49%
opposed baiting and 45% supported.
2
A 2003 survey of Georgia hunters revealed that 53% opposed baiting and
40% supported it.
3
The 2001 Georgia Poll revealed that 72% of Georgians opposed baiting
and 19% supported baiting.
4
A basis for opposition to baiting seems to be one of ethical judgment.
Survey respondents opposed to baiting believed that baiting was unethical or
that baiting threatened to decrease the quality of deer hunting in Michigan.
5
Fair chase is an ethical concern. Fair chase is a set of hunting
conditions in which the individual judges the taking of prey as acceptably
uncertain and difficult for the hunter. Fair chase issues draw non-hunters
attention to the baiting controversy. Non-hunters’ perceptions of
“unsporting” behaviors can also create a poor image of those who participate
in or allow such practices, and thus erode the credibility of the agency and
its hunting constituents.
6
In a 1994 telephone survey of random households, if respondents opposed
to all hunting (12%) were dropped from analysis, 58% of non-hunters found deer
hunting with bait to be unacceptable. Baiting could cause a backlash on
hunting.
7
In areas dominated by small land ownerships, baiting impacts
surrounding landowners and hunting clubs by changing deer movements. Baiting
would become an issue of “self-defense” across much of the deer range with
adjoining clubs attempting to “hold deer on our property”. Baiting on public
lands is definitely detrimental since it creates real hunter conflict
problems.
Legal and Enforcement Issues
1
Nationally, hunting deer over bait is currently illegal in 30 states.
2
In the southeast, baiting is legal in Florida, North Carolina, and the
low country of South Carolina (actually not even addressed in the low
country). Whereas, it is illegal in Alabama, Georgia, Tennessee, and
Mississippi.
3
Use of bait may facilitate illegal activities such as shooting deer at
night over bait or shooting turkeys out of season. The nocturnal movements
associated with baiting enhance the likelihood of late shooting or even the
establishment of lighted bait sites.
Public Safety
1
Deer baiting sites located near well-traveled roadways may increase
deer-vehicle collisions.
2
In South Carolina, deer vehicle collisions are 9% greater in the low
country, where baiting occurs, than in the upstate where baiting is illegal,
despite the fact that human population densities in the low country are 31%
less than human population densities in the upstate.
3
Deer conditioned to human food sources can lose their wariness of
people.
In summary, the overriding issue may be the
opinions of non-hunters, not hunters or biologists. The consistent opinion of
Georgians toward hunting deer over bait is opposition to this activity. The
practice of baiting lends ammunition to anti-hunting groups. Animal rights
activists claim that hunters are only interested in the kill and baiting
provides credibility to that statement.
Despite the overwhelming perception,
there is no evidence that deer baiting increases the overall success rate.
Baiting provides a concentrated source of food, thus reducing deer activity.
This causes deer to be less vulnerable to hunter harvest, which will lower the
success rate as it does for other factors, like the weather. High
carbohydrate foods used as bait are known to have harmful effects on deer
health under certain circumstances due to lactic acidosis, which also
contributes to reduced deer activity. As browser, white-tailed deer cannot
readily digest grain and hay as well as parts of forbs, shrubs, and trees.
The cumulative effects of baiting (and feeding) deer can change natural deer
productivity and survival rates to unmanageable levels. Deer baiting is not as
innocuous as some claim. Deer baiting affects the hunting experiences of all
hunters, and is increasingly disruptive to hunters who choose not to bait.
Based on other states experiences, legalizing hunting deer over bait in
Georgia would result in less deer sightings and a reduction in the deer
harvest. It would also increase conflicts among hunters, increase the spread
of diseases and have a negative impact on the public perception of hunting.
