    As the days get longer and the snow starts melting, both hunters and bears are becoming more active in the Upper Snake Region. "Whether you are pursuing bears, turkeys, or just out enjoying the spring weather, people need to be aware that they are in bear country," says Jeremy Nicholson, Bear Biologist for the Idaho Fish and Game. "Both grizzlies and black bears have been seen on trail cameras in the Island Park area recently and lots of people have been seeing tracks."

    Information Sought in Panhandle Grizzly Bear Shooting, reward available

    An adult female grizzly bear was shot and killed near Spruce Lake in northern Boundary County over Labor Day weekend. Grizzly bears are protected by both state and federal law and the loss of a breeding female is a major setback to the great bear’s recovery in the Cabinet-Yaak Ecosystem.

    Young grizzly trapped and relocated in Eastern Idaho

    On Aug. 8, Idaho Fish and Game personnel captured a yearling grizzly bear in a research trap near Big Springs. Grizzly bears typically stay with their family group until they are two years old. Biologists were uncertain why this young bear was not with its mother, but it was in good condition and making it on its own.

    This was not a management or conflict capture, but the young bear had been seen near Mack’s Inn on a couple of occasions and it was always alone. Biologists fitted it with a GPS collar and relocated it to an area with less human activity.

Health Issues Which May Affect This Animal

What Causes This Disease?

Trichinosis is a disease caused by a nematode parasite, Trichinella spiralis.

Where Is The Disease Found?

Trichinosis occurs throughout North American and can be found in grizzly bears, polar bears, black bears, feral swine, mountain lions, wolverines, wolves, coyotes, and foxes. Trichinosis has been documented in black bears and mountain lions in Idaho. Trichinosis has been documented in humans associated with consuming home-made jerky made from a cougar and a black bear in Idaho.

Signs of Disease

Animals infected with trichinosis generally appear healthy. Trichinosis is hard to detect when butchering because there are few lesions and the cysts are very small. The cysts are most common in the muscles of the jaw, tongue, and diaphragm. Animals that are infected with adult worms may have swollen intestines with small bruises on the intestinal wall. Affected muscles and associated lymph nodes may be soft and swollen.
