JACKSON, Wyo. (AP) — Federal biologists will begin trapping and tagging grizzly bears in Grand Teton National Park this coming week. The effort by the Interagency Grizzly Bear Study Team is aimed at keeping tabs on the Greater Yellowstone Ecosystem's grizzlies. The grizzly trapping in the Tetons will continue until mid-October. All trapping operations are located in the backcountry and away from hiking trails and campsites. The precise locations where the study team sets its traps are not publicized. Grand Teton spokeswoman Jackie Skaggs tells the Jackson Hole News & Guide that biologists don't want people interfering with their work. Skaggs said bears were last targeted in Teton park either two or three years ago.
