Although grizzly bears don’t inhabit the Bitterroot Valley in numbers like they do in many other parts of western Montana, grizzlies are dispersing into more places. Activity in the Bitterroot Valley has steadily increased over the past 10 years.
Montana Fish, Wildlife & Parks bear specialist, Jamie Jonkel, said the recent sightings serve as a reminder of the bears’ natural expansion and possibility to be present in more places.
“We have established populations of grizzly bears to the northwest and southeast of us, so seeing bears moving through the greater Missoula area and Bitterroot is becoming more common,” Jonkel said.
Two sub-adult grizzly bears were first noted in the lower Blackfoot Valley earlier this month before beginning to move south. The Blackfoot sits on the southern end of the Northern Continental Divide Ecosystem, an established population of grizzly bears, and is a fairly typical spot to see grizzlies. The Greater Yellowstone Ecosystem, home to another established population of grizzly bears, sits several hundred miles to the southeast.
After moving out of the Blackfoot, the pair began venturing further south, where it is less common to see grizzlies. FWP linked together a series of sightings, photos, and video, which showed they first crossed Interstate 90 just east of Missoula, near Turah, around Aug. 4. They then traveled south into the Sapphire Mountains and were sighted again near Florence, in the northern Bitterroot Valley, a few days later.
The bears are believed to be around two years old, which is a natural time for some bears to begin venturing out and exploring new territory.
Although the bears were reported to cross U.S. 93 and spend a little time on the west side of the Bitterroot, they are now believed to be back on the east side of the valley. The grizzlies were most recently seen in the Bitterroot River bottom, just south of Lolo, on Aug. 18. The tracks of a possible third grizzly bear have also been reported in the same area.
Jonkel says that although the bears are active and near human activity enough to be noticed, he hasn’t heard of any conflicts with people or livestock so far. They seem to be exploring but naturally trying to keep their distance.
“We’d like to do all we can to keep it this way,” Jonkel says. “This time of year, our valleys draw bears looking for berries and other food sources. If we can keep them away from unnatural foods like garbage, bird and pet food and other attractants, they’ll hopefully keep on moving along and exploring their natural habitat.”
Black and grizzly bears can be found throughout much of the western half of Montana, so it is important to review bear safety tips and keep the areas around your home free from bear attractants to prevent issues for bears and people. Consider these tips:
- Be aware of your surroundings and look for bear sign.
- Read signs at trailheads and stay on trails. Be especially careful around creeks and in areas with dense brush.
- Carry bear spray, have it close at hand and know how to use it.
- Travel in groups whenever possible and make casual noise, which can help alert bears to your presence.
- Stay away from animal carcasses, which often attract bears.
- Follow food storage orders from the applicable land management agency.
- If you encounter a bear, never approach it. Leave the area when it is safe to do so.
Keeping bear attractants secure, out of a bear’s reach, is especially important. When out, keep clean camps, store food and any other scented attractants securely away from sleeping areas and follow all food storage regulations. Around home, be sure to keep garbage indoors until the day of collection; remove bird feeders when bears are out and active; consider using electric fencing around chickens, garden areas and compost piles; and move other attractants such as pet food, dirty barbecue grills and ripe fruit indoors or into a secure building.
