F&G begins annual grizzly bear research trapping in the Caribou-Targhee National Forest

Captured bears are immobilized and handled in accordance with strict protocols developed by the Interagency Grizzly Bear Study Team. Bears that meet the criteria are fitted with a radio collar. By observing radio-collared females, biologists can document age of first reproduction, average litter size, cub and yearling survival, and how often females produce a litter. Data collected from both sexes provides the estimated survival among different sex and age classes, causes of mortality, and a better understanding of habitat use and food habits.
