Missouri bears growing in number, now awake from winter slumber
A study estimates there may be more than 200 bears in southern Missouri, and conservation are getting many more hard facts about the state's bear population.

MISSOURI BLACK BEAR STUDY
To date, MDC biologists have
fitted 61 adult bears with radio
collars. They have also set 785
hair snares in 11 counties in the
southern part of the state. These snares are small wire enclosures that collect small tufts of fur
from bears crossing the wire to get to the bait in the center. These tufts of fur, and the tiny skin
follicles attached to them, can reveal valuable genetic information about the bears. Hair
samples have been collected from 141 bears.
MDC Resource Scientist Jeff Beringer is the project leader of the research study. He said that
information gathered so far has led to a state-wide population estimate of approximately 225
black bears, although much work remains to validate this preliminary estimate.
Home ranges of female bears show that most are in four separate reproducing populations
ranging over 10 counties in south-central Missouri.
DNA evidence suggests the largest of these populations, located in Webster and Douglas
counties, may be a remnant of Missouri's original black bear population. Those elsewhere in
the state are presumably descended from bears brought to Arkansas from 1958 through the
late 1960s as part of a re-introduction program and later dispersed into Missouri.
Beringer believes that the other populations in Missouri developed when female bears brought
to Arkansas travelled north after being released in an effort to return to their birth areas in the
upper Midwest.

upper Midwest.
Research data has also revealed
valuable information about the
annual life cycle of a Missouri
bear. Bears in Missouri spend
nearly all their time in forested areas and use wooded corridors when moving cross-country.
Adult bears can consume as much as 20,000 calories per day – mostly in the form of acorns –
in preparation for winter dormancy. Females den earlier than males and males emerge from
winter dormancy earlier than females. The exact timing of this emergence depends on weather
and on how much fat they are able to accumulate before denning.

June is the peak month for breeding. This is also the peak month for dispersal of young male
bears. Young females tend to remain near or even with their mothers in their home ranges. The
study is an example of how the Missouri Department of Conservation works with people and
for people to sustain healthy forests, fish and wildlife.
The study isn't completed yet. Beringer said there's still more to be learned about the black
bear in this state. "We think we know how many bears we have now," he said. "Our next project
is to figure out how fast our population is growing. We want to learn female survival rates, how
old are they when they have their first litter, how many litters do they have in a lifetime, how
many cubs do they have and what is the survival rate of the cubs."
As a way of reducing the number of bear-human conflicts occurring in Missouri, one of the
outcomes of Missouri's bear study might be the institution of a limited bear-hunting season. If
the data supports a hunting opportunity, Beringer said it would be a highly regulated season
favoring the harvest of males and would take place in the winter when females are in their dens
. However, before recommending a hunting season, Beringer said he needs enough
information to predict how an annual harvest will affect the overall population.
In the meantime, Missourians should keep in mind that early spring is the time of year when
bear activity increases in Missouri. This period, which begins in spring and stretches into early
summer, is when black bears may appear around farms and rural outbuildings in search of
food. Black bears are inquisitive and intelligent and that's what can get them into trouble.
Like any wild animal, black bears are constantly searching for their next meal. When they are
successful at finding food, they remember where it came from. Most problems people have with
bears come from them raiding campgrounds, garbage bins, bird feeders, orchards and
beehives.
Missourians care about conserving forests, fish and wildlife, but some people's fascination with
bears over-rides their conservation-oriented instincts. This happens when bears are purposely
fed by people who think they're helping them survive or are trying to lure them into range for a
good photo. If a bear visits an area and is rewarded with food, it will very likely return. Though
they are generally not aggressive, they are powerful and can cause substantial damage to
buildings, trailers, vehicles, and just about anything else that they view as an obstruction in their
search for food.
"We have had an increase in bear/human conflicts in recent years," Beringer said. "Most
conflicts can be prevented if folks do not give bears access to food or garbage."
