“Our bear population was increasing quite fast
during the 1980s and ’90s, and the only way to
control it was to increase the number of hunters,’’
said Karen Noyce, DNR bear research biologist
in Grand Rapids.

Minnesota’s black bear population — which now numbers 10,000 to
15,000 after peaking around 25,000 — appears
to have stabilized

To do that, the DNR made more hunting permits

It worked. Maybe too well.
In 1985, those 3,700 hunters killed 1,340 bears,
but in 1995, the number of hunters had jumped to
11,600, and they harvested nearly 5,000 bears.
Over the next 10 years, hunters averaged 3,500
bears yearly.

Last year and this fall, the DNR offered just
3,750 permits, the fewest in 30 years. (Hunters
don’t need those permits in some areas.)
Hunters killed just 1,618 bears this fall, the
lowest in 26 years. About 6,200 people hunted
bears, the lowest since 1989. The season
ended Oct. 12.

Fewer bear hunters in the woods is OK,
officials say. When hunter numbers were
at a peak, Noyce said, hunters complained
the woods were too crowded and the quality
of the hunt fell. Though bear hunter numbers
have fallen because of the reduced availability
of permits, interest remains high: More than
18,000 people applied for permits last year.

Estimating the population of bears — and
managing that population — is tricky business.
The DNR puts out baits laced with tetracycline,
an antibiotic. The chemical is deposited in the
teeth and bones, and can be detected later
in bears killed by hunters.

Successful bear hunters are required to
submit two teeth from their animals to the
DNR. The percentage of those bears with
tetracycline allows researchers to estimate
the population. The DNR also uses the teeth
to age bears, which also provides a way to
estimate the population.

The amount of natural food in the woods can
vary dramatically, and that has a big impact
on whether bears will be lured to hunters’ baits
and killed.

“The harvest fluctuates a lot each year for

Noyce said.
“In 1995, we shot nearly 5,000 bears. The
very next year we shot less than 2,000 bears
with similar number of hunters.’’ The difference
was the availability of food. Lack of natural food
in the woods also triggers more nuisance bear
complaints as bruins seek out food at bird
feeders or garbage cans.
