Species: Bear
| Protection Level
|
The black bear is a large mammal with powerful limbs, a relatively
small head, small ears, and black fur, although several less common
color phases (e.g., cinnamon) can occur in this species (Figure
1). Its muzzle or snout is light brown or tan in color and
some bears may have a small, white chest blaze. This species has
five toes, each with a well developed claw, on both the front
and hind feet and has teeth adapted for feeding on plants and
animals. Adult females typically weigh 100-200 lbs. whereas adult
males are larger, weighing 150-400 lbs.
When natural foods are scarce, bears will turn to whatever food
resources are most available. As a result, conflicts between bears
and agricultural producers, homeowners, outdoor recreationists,
and other affected parties may arise where bears cause damage
to personal property (Figure
2) or crops (Figures
3 and 4) as they search for food. Even so, because of their
inherent value, every effort should be made by Virginians to co-exist
with bears.
Unlike other species of bears, black bears rarely attack humans
and very few deaths have been attributed to them. However, black
bears can become aggressive, particularly those animals that have
become conditioned to humans (e.g., bears that frequent campgrounds
or landfills), and such encounters can result in serious injury
or death. Therefore, it is best not to provoke a bear, tempt one
with food, or encourage bears to remain around the home, farmstead,
or campsite.

In Virginia black bears are deemed a game species. Black bear
can only be taken during the designated hunting season §29.1-100,
§29.1-513.
If the preventative measures outlined below do not prove fruitful
in deterring black bears from causing damage to a homeowners property,
the homeowner can contact the Virginia Department of Game and
Inland Fisheries (VDGIF) to have a Game Warden visit their property who
will deem the best course of action for dealing with the problematic
animal. The contact for a local game warden can be found on the
Who to Call page.
In Virginia it is illegal to
• trap bear at any time. 4VAC15-50-100
• kill a bear anytime other than during a defined bear hunting
season. §29.1-100,§29.1-513
• poison any animal (including bear) other than rats and
mice on your property. 4VAC15-40-50
In Virginia it is legal to
• contact VDGIF to access damage and determine if a damage
permit is warranted. The VDGIF reserves the right to trap and
move problem bear. §29.1-529

To reduce the potential for damage to personal property, precautions
should be taken before a bear develops an interest in or gains
access to potential food sources. As with most wildlife damage
problems, no single technique exists that will provide absolute
protection from bear depredations. However, certain measures that
are initiated in a timely fashion, maintained properly, and applied
with an understanding of the habits or behaviors of bears can
reduce the likelihood of significant damage. Individuals residing
within the bear's range should remember that although bears generally
are shy creatures, they are intelligent and possess good long-term
memory. Additionally, these are wild animals; they will react
to threatening situations accordingly. Therefore, any proposed
damage management program for bears must take these traits into
account.
Preventive Measures:
To reduce the potential for damage by black bears around the
farm or home, don't encourage their presence or attract them to
your property. Methods to accomplish this include:
- exercise good husbandry practices on the farm and around
the home (i.e., be neat and clean),
- remove all potential sources of supplemental food, such as
readily available garbage or refuse, pet foods, bird feeders
(especially suet after late-March), or animal carcasses,
- move domestic farm animals into protected areas and away
from areas with heavy cover,
- maintain well-mowed, cleared corridors (of up to 50 yards
where feasible) around beehives, agricultural crops, and livestock
holding areas, and
- alternate or strip plant row crops, particularly sweet corn,
to provide less protective or hiding cover for bears.
Outdoor recreationists should never feed bears or improperly
store foods in or near the picnic or camp site -- this will only
attract bears and habituate them to humans. Campers should learn
how to properly hang food well above the ground and between two
trees -- remember, black bears are excellent tree climbers.
Non-lethal Controls:
Non-lethal controls are used to prevent or deter a bear from
gaining access to property or a commodity. Examples of non-lethal
measures include use of:
- loud noises (e.g., horns, clapping, shouting, pyrotechnic
salutes), bright lights, or other harassment measures,
- temporary or permanent electric or heavy woven-wire fencing
(Figure
5). The effectiveness of electric fencing often can be enhanced
by baiting it with peanut butter, bacon grease, or sardine oil,
- bear hounds or guard dogs to ward off depredating bears,
- habitat manipulation (e.g., removal of protective cover)
to make a site unsuitable for or unattractive to bears, and
- state wildlife personnel to capture (Figure
6) and relocate an offending bear, where appropriate and
feasible (note: it is illegal for homeowners or private individuals
to capture a live bear without special authorization. Consult
the nearest Virginia Department of Game and Inland Fisheries
Regional Office for technical assistance or additional information
relating to the translocation of problem bears).
Currently, only Capsaicin (concentrated hot pepper spray) is
registered for use on bears as a personal protection repellent.
Spray canisters used to propel this material have a maximum range
of about 30 feet, so effective use of this material demands that
an applicant be in close proximity to a bear. However, recent
research has shown that bears may actually be attracted to the
taste of weathered Capsaicin residue, so care is needed in how
and where this material is applied. There are no fumigants or
toxicants registered by the Environmental Protection Agency for
use on black bears.
Lethal Controls:
If all attempts to deter bear depredation with preventive or
non-lethal measures fail, removal of an offending animal may be
necessary. Where damage to fruit trees, crops, livestock, or personal
property has occurred, the owner or lessee of the property may
receive authorization to destroy an offending bear, but only after
such damage has been reported to and verified by the local game
warden. The warden will then issue a written permit that clearly
states any limitations on taking the bear (e.g., length of time
permit is valid, authorized methods of kill, disposition of carcass)
and establishes how and when any successful take must be reported.
To report suspected damage by a bear, to receive help in removing
a troublesome bear, or to request a permit to take a bear, contact
your local game warden by calling the Virginia Department of Inland
Fisheries regional Office. This number can be obtained from the
Who to Call page.

Life History
Back
to Top
Black bears are present throughout much of Alaska, Canada, and
the western and north central United States. In the East, they
occur primarily along the Appalachian mountains from Maine to
Florida. Virginia has a healthy, resident black bear population,
the bulk of which is located west of the Blue Ridge Mountains,
while another smaller segment exists in the southeastern corner
of the state, centered around the Dismal Swamp. The distribution
of bears in the commonwealth is expanding and bears are being
observed more frequently in many areas within the Piedmont Region.
An exact figure for the bear population in Virginia is not known,
but current estimates place it between 3,500 and 4,500 individuals
statewide.
Black bears can be found in a variety of habitats, ranging from
mature hardwood forests to 1- or 2-year old clearcuts comprised
of thick, brushy regeneration intermixed with open weedy areas.
They also use riparian and wetland areas as sources of food and
cover, and particularly as travel corridors. Although black bears
have a digestive system typical of a carnivore, by necessity they
pursue an omnivorous existence; that is, they feed on a variety
of both plants and animals. Bears work very hard to acquire sufficient
food to survive and to prepare for the physiologically demanding
overwintering period. The diet generally is a reflection of the
foods available at a particular time of year. For example, bears
may feed on skunk cabbage, squawroot, and tender grasses in spring;
berries, fruits, and sedges in summer; and hard mast, such as
acorns, beechnuts, and hickory nuts in fall. Insects, small mammals,
and deer fawns also may be consumed when available. Bears will
seek out and use alternate and readily available food sources,
such as agricultural crops, the contents of beehives, and occasionally
livestock, particularly when natural foods are not abundant.
Except for females with young and during the breeding season,
black bears are solitary animals. During spring, summer, and fall,
and especially during the breeding season, bears are active throughout
daylight hours, but most commonly they are active around dawn
and again at dusk. However, they rarely are seen because they
are quite secretive and, for such a large animal, very quiet.
Bears often become nocturnal where contact with humans is frequent.
Individuals of both sexes will establish overlapping home ranges;
those used by females are smaller (about 10-15 sq. mi.) than those
of the more far-ranging males (about 20-30 sq. mi., but as much
as 120 sq. mi.). Females typically do not breed until they are
3-5 years old, and then they reproduce only every other year.
Breeding occurs during June or July, but embryonic development
does not begin until late November or early December, a process
known as delayed implantation. Two to four cubs are born in late
January or early February while the female still is denning. These
cubs will remain with the female throughout the next winter denning
period and disperse the following spring. At that time, young
males will move out of their mother's home range whereas
young females usually establish a range close to or overlapping
with that of the mother. Mortality is highest among dispersing
yearlings, especially males, as they travel considerable distances
in search of suitable, unoccupied habitat. Although bears more
than 20 years old have been captured in Virginia, such advanced
ages are not common. The average age of a female bear is about
5 years whereas males average about 3 years.
Bears will den (overwinter) in brush piles or logging slash,
large hollow trees, rock outcrops, the upturned root mass of a
blown-down tree, or simply at the base of a large standing tree.
The onset of and emergence from denning is dependent upon food
availability, but often begins in early November and extends until
mid-March and early April. Black bears do not enter a state of
"true" hibernation, given that a bear's heart and respiration
rates and body temperature decline only slightly while denning.
A denning bear will "wake up" if disturbed or may move
to a new site if the winter den they selected is not ideal or
if it is subject to disturbance. Bears do not urinate or defecate
throughout the entire winter.

Wildlife Information Service Web page.
