A Grizzly Biologist's Journal

For the past 20 years, I have been conducting grizzly bear research or management
for Montana Fish, Wildlife & Parks along the Rocky Mountain Front. Since
the mid- 1970s, when the species was listed as threatened under the Endangered
Species Act, the population of Northern Continental Divide Ecosystem grizzly
bears has been slowly growing and expanding. Now they are spilling east from
the Rockies into their historic low-elevation native prairie habitat, where
they were exterminated in the early 1900s. As they reoccupy their traditional
range, grizzlies are increasingly coming into conflict with ranchers and
others living along the Front. My job as one of FWP’s four grizzly
bear management biologists is to better understand grizzlies and find ways
to reduce those conflicts. These photos, which I’ve taken over the
past two decades, document some aspects of bear-human conflict issues. I
hope they help people better understand why these conflicts occur and what
ranchers, FWP, and the grizzlies themselves are doing to help people and
bears coexist on the landscape.

Grizzly bears, like this female I photographed at left, are intelligent,
mysterious, and captivating creatures. But people haven’t always thought
so. Grizzlies were hunted, trapped, and poisoned nearly to extinction 100
years ago. By the 1930s, even seeing a track along the Rocky Mountain Front
was rare. Over the decades, however, grizzly numbers began to grow. Below
left is the Front overlooking Blackleaf Creek, 20 miles northwest of Choteau.
It shows the diverse mosaic of habitat where the foothills turn into prairies,
with riparian shrubfields and hay meadows. These low-elevation grassland
habitats, also seen in the photo of sibling yearling bears below, are where
grizzlies lived before white settlement. Now grizzlies have begun to reoccupy
these areas, which
are often private ranchlands. That’s where many conflicts occur.
I
took the picture at right by crawling into a large den where a massive 465-pound
female grizzly and three yearlings had hibernated the previous winter. Above
right is biscuitroot, an important plant food dug up by grizzlies in subalpine
areas.
As grizzlies expand their home range, they move into areas used by humans. That’s where the bears get into trouble, such as by tearing up bee hives for honey and larvae. Elsewhere, grizzlies have learned to feed on garbage, birdseed, and pet food left outside, putting them in close contact with people.
Many conflicts are between bears and ranchers along the Rocky Mountain Front.
Dusty Crary (left), who raises cattle near Choteau, is a typical Montana
rancher learning to deal with grizzlies. His land has some terrific wildlife
habitat that naturally attracts grizzlies. Unfortunately, grizzlies occasionally
prey on livestock, with young calves being the most vulnerable. Defenders
of Wildlife, a national conservation group, has been helping Crary and other
ranchers by compensating them for the market value of livestock lost to grizzlies.
Each spring, newborn calves die of natural causes. Their carcasses become bear magnets. We encourage ranchers to remove any dead animals to remote areas of their ranch, away from homes, barns, and corrals. For ranchers who don’t have remote areas, we bring in a specially outfitted FWP truck (below right) and redistribute carcasses onto other lands. Another way of reducing conflicts is with aversive conditioning. We use rubber bullets or cracker shells (fired from shotguns), propane-operated scare guns, Karelian bear dogs, and electric fences, like the one above right erected around a sheep bedding ground. These scare tactics help bears learn to avoid human dwellings and areas where livestock frequent.
If removing food attractants doesn’t work and aversive conditioning
fails, we trap and relocate problem bears. In the photograph above is a female
grizzly and her two cubs, which were trapped near bee hives they had been
damaging. We tranquilized the bears, took tissue and blood samples, attached
a radio collar to the mother so we could track her movements, and then relocated
them to a remote site.
We once thought it was best to take bears as far as
possible from where they caused problems. But we found they usually returned.
Now we relocate them in a remote portion of their home range, where they
are familiar with the territory and can get back into natural feeding patterns.
When coupled with preventive measures such as electric fences, this method
seems to work. In the photo at left, we are transporting a grizzly to a short-distance
relocation site along Dupuyer Creek.
Ranchers, biologists, outfitters, and others who deal with bears are always
learning new ways to reduce conflicts between bears and humans. They have
to. Grizzlies will continue to expand into more and more areas as they reoccupy
historic habitat. The better we can anticipate and prevent bear-human conflicts,
the easier it will be for people and grizzlies to coexist.
