The First Release of Bears
for the Black Bear Radio-Telemetry Research Project!

Returning to the Forest
Mike Gappa, Wildlife Manager, Wisconsin DNR, has an opportunity. Two black
bear cubs are orphaned and need assistance to survive. In the past these
types of bears are raised in captivity, given to zoos, or even just dropped
off in the woods in hopes they will survive. These bears are different,
they will be raised to yearling age, and released back into natural habitat.
The catch is; they will be radio collared and tracked to see what happens
to black bears which are reintroduced to the wild. A long list of questions
could be answered about reintroducing bears if this project succeeds.
The story begins at the prerelease meeting at Beaver Creek Reserve outside
of Fall Creek, Wisconsin,where Gappa introduces Dan Mautz, the biologist
who raised the bears for the last several months. Phase one, raise the
bears in captivity.
The bears were brought to Mautz at the Makenzie Environmental Center near
Poynette directly from the den site where they were found abandoned. The
mother bear was injured by logging equipment and did not return. The new
cubs needed care if they were to survive. All efforts were made not to
imprint the bears with human contact. Special handling was used to keep
a distance from the bears so they wouldn't associate humans with "food".
Unlike two other yearlings which were released last year, these two bears
would be kept as "wild" as possible. Last year's experiment ended with
both of the bears dropping their collars, and one becoming a nuisance animal.
This year everyone involved hopes for a different story to develop.
Mautz tells the students, teachers and press in the group the about the
problems of raising bear cubs. They really have to work at not imprinting
them. This past year these two bears were kept in an enclosure, shrouded
with dark cloth so they would not be exposed to the unnatural environment
of the Makenzie Center where they were being raised. However, they were
still in a civilized environment; that was the unknown factor. They were
bottle fed for a couple weeks when they first arrived. For a couple weeks
the cubs were fed and then placed immediately back into the makeshift den.
Shortly after that they began taking food out of a pan. When that happened,
the staff did not have any need for close contact with the bears. Mautz
says his focus is to not only try to avoid physical and feeding imprinting,
but visual imprinting as well.
The bears reacted with apparent "fear" of humans during their captive period
and Mautz hopes that reaction will continue so they adapt to their wild
surroundings and avoid humans as most bears do.
Mike Gappa is asked several questions by the students who are going
along
on the release trip. Much of what is discussed is about last years project
and the failed attempt to track those first two bears. Gappa's feeling
is the collars were not on tight enough and the bears were too imprinted
on humans. After they emerged from the den both bears found their way to
human settlement in search of an easy meal of garbage or handouts. This
year things should be different. Everyone receives instructions for the
day and its off to the vehicles for the drive to the den site. Phase two,
reintroducing the bears to the wild.
Several four wheel drive vehicles are needed to get the bears and the crew
back to the den site. The crew includes teachers and three students from
each of Augusta, Altoona, and Fall Creek High Schools, media crews, Makenzie
Center personnel, Beaver Creek personnel and Gappa. The snow is deep and
pushing trucks is the order of the morning. After blazing a trail through
deep snow the bears and the people finally arrive at a site close to the
den. The bears are still in the den box which they have called home since
they arrived in the care of the DNR last spring. Awake and probably shaken
up from the rough trip in, they peer curiously out of the box door as Gappa
and Mautz open it and peer curiously in. Everyone in the group gets their
first look at the newest inhabitants of the Eau Claire County Forest.
Gappa takes what looks like a tackle box from his truck and explains to
the students, "this is my bear box, it has everything I need to work with
bears in the field." After explaining about several of the items in the
box he prepares a sedative which will relax the voluntary muscles of the
bears. While still allowing the bears to maintain other bodily functions
like breathing, heart beat etc.., the sedative will keep the bears "sleeping"
long enough to prepare them and get them to the den site. After sedating
both bears, the little male bear is removed from the box and laid on a
blanket for examination. Gappa explains how to age bears using their teeth.
He says, "there is no need to do that to these bears because we know how
old they are, but with other bears in the field a tooth is removed and
aged much like a tree. The tooth is cross-sectioned and annual rings are
counted." The students are recording all the data on the bears for the
project.
A student then helps put an ear tag on the bear for numerical identification.
The tag will stay with the bear for its entire life. Then the students
weigh the bear, 100 pounds on the money. Throughout this whole process
the snap of cameras can be heard from the press and teachers who are along
documenting the event. The bear is then collared and readied for the trip
to the den. The same process is followed for the female, however she requires
a second attempt with the sedative, Gappa says he hit fat on the first
try, the drug needs to be injected into muscle to be effective. She weighs
in at 45 pounds.
Both bears are now ready to be moved to the den site. The den site is approximately
a quarter mile from where the bears are prepped. Students pull the sedated
bears to the den on small plastic sleds. Through knee to thigh deep snow
the students pull both bears to the den. The straw and vegetation, which
lined the den box during the past months, are also brought along to line
the new den. This will hopefully provide some familiarity when the bears
awake.
Two students crawl into the den which was constructed from a large pine
tree which uprooted and fell over. The roots still had many feet of soil
attached to them forming a natural wind break. The tree trunk was covered
with pine boughs to shelter the bears in what was now very much like a
small cave. The students prepare the den by spreading the den materials
out on the ground. Then its time for the new residents.
Both bears, still sedated, are brought one by one to the den. Two students
are in the den to help position the bears. As the male is passed to the
students one girl asks, " when will the sedative wear off?" Gappa replies,
"any time now". Which is followed by the comment from the girl in the den,
"I think he's waking up right now!" Without hesitation Gappa reaches into
his hatband, removes the syringe and injects a booster dose into the bears
hind leg muscle. The girls in the den are relieved and continue their work
putting both bears together on the den materials.
As the girls emerge from the den everyone in the crowd is trying to get
a good angle to see into the den and check on the bears. The job is done.
Now its time to think about the job ahead, tracking and locating the bears
throughout the rest of this season. Hopefully ending with locating them
when they den again next winter, then returning to them and removing the
radio collars. However, that is many months into the unpredictable future.
The experiment has begun, the bears are home. The group makes its way back
to the trucks with a sense of accomplishment. Time to start phase three,
tracking the bears.
