While
some bears in western states may prey on livestock, there
have been no reports of livestock depredation by the
Louisiana black bear in recent history. Bears will enter
livestock enclosures to feed on livestock food and several
complaints have been received in Louisiana where bears were
in hog or goat pens, eating feed and excluding the livestock
from the feeders. As the bear population expands into new
areas, however, owners of crops and livestock in or close to
occupied bear habitat should employ preventative measures to
exclude or minimize the potential for bear damage.
Crops
and livestock should be inspected frequently so that any
damage can be discovered quickly, and preventive control
measures can be implemented. Gardens, small fields and
pastures should be protected with bear-resistant fences if
bear damage is anticipated. Farmers should harvest crops as
quickly as possible and consider planting crops that are not
attractive to bears.
There
are several alternatives to control bear damage to crops and
livestock. Intensive herding practices can lessen the chance
that bears will prey on livestock. Carcasses of dead animals
should be hauled to an approved landfill or destroyed by
deep burial or incineration to prevent bears from scavenging
near susceptible livestock.
Fields
or pastures susceptible to bear damage can employ gas
exploders, noise-making pyrotechnics, strobe lights,
electronic sirens and noise generators, or scarecrows to
temporarily repel bears. Long-term and repetitious use of
these devices, however, may render them ineffective.
Livestock guardian dogs (LGD’s) such as Anatolian Shepherds
or Great Pyrenees are becoming more popular with goat,
sheep, and chicken farmers, mostly as a deterrent to fox,
coyote, and feral dog depredation. But the LGD’s should also
be effective in dissuading bears from investigating the
livestock area. At some point, if damage occurs, USDA
Wildlife Services or the state wildlife agency should be
contacted for further control strategies. |
