As part of ongoing efforts required under the Endangered Species Act to monitor the population of grizzly bears in the Greater Yellowstone Ecosystem, biologists with the Interagency Grizzly Bear Study Team will conduct pre-baiting and trapping operations in Grand Teton National Park from May 1st through July 15th.
When bear trapping activities are being conducted, the area around the site will be posted with bright warning signs to inform the public of the activities occurring. For bear and human safety, the public must respect these closures and stay out of the posted areas.
Once trapped, the bears are sedated to allow wildlife biologists to collar the bears and collect samples and data for scientific study. The bears are then released on site, often with a collar that transmits their location to study how bears use the landscape. Such trapping operations are conducted annually.
