Tragic Loss of Iconic Grizzly Bear 399 Shakes Conservation Community

A well-known grizzly bear, referred to as “Grizzly Bear 399,” was killed by a vehicle at Grand Teton National Park in Wyoming. The incident occurred on Tuesday evening on Highway 26/89 in Snake River Canyon, just south of Jackson, Wyoming. Park officials confirmed her identity via ear tags and a microchip.

Grizzly Bear 399 had a yearling cub with her, whose current location is unknown. Authorities stated there is no indication that the cub was involved in the incident, and the U.S. Fish and Wildlife Service is monitoring the area for updates.

Vehicle collisions with wildlife, including grizzly bears, are a common occurrence. Between 2009 and 2023, there have been 49 grizzly bear deaths due to vehicle strikes in the Greater Yellowstone Ecosystem. The National Park Service is collaborating with state and local authorities to gather further details regarding this latest case.

Hilary Cooley, Grizzly Bear Recovery Coordinator for the U.S. Fish and Wildlife Service, noted that Grizzly Bear 399, at 28 years old, was the oldest known reproducing female grizzly bear in the area and had a following of admirers worldwide. Angi Bruce, Director of the Wyoming Game and Fish Department, expressed gratitude that the vehicle’s driver was unharmed, though the community is mourning the loss of the beloved bear.

This year, two grizzly bear fatalities from vehicle strikes have been recorded in the Greater Yellowstone Ecosystem. On average, the region has seen approximately 3.3 grizzly bear deaths per year due to such incidents from 2009 to 2023.

Grand Teton National Park Superintendent Chip Jenkins highlighted Grizzly Bear 399’s role as a symbol for the species, stating she has inspired many to engage in conservation efforts globally and will be deeply missed.

No further information has been released, and the investigation into this incident is ongoing.
