Wildlife Crossings: Protect the Legacy of 399
On October 22, 2024, Grizzly 399, a beloved and iconic bear, was fatally struck by a vehicle on Highway 26/89 in Snake River Canyon. At 28 years old, she was the oldest known reproducing grizzly in the Greater Yellowstone Ecosystem, renowned for raising 18 cubs and captivating wildlife enthusiasts worldwide. Her frequent presence near roads in Grand Teton National Park made her a symbol of the delicate coexistence between wildlife and humans.
The collision, deemed accidental, highlights the critical need for safer roads in wildlife corridors. Between 2009 and 2023, 49 grizzlies were killed by vehicles in the region. Grizzly 399’s death underscores the urgency of mindful driving and wildlife-friendly infrastructure to prevent future tragedies.
Let her legacy inspire action. Slow down, stay alert, and advocate for wildlife crossings to protect these magnificent creatures and their habitats. Together, we can honor her story and safeguard the future of wildlife.
