Key Takeaways
- 63 grizzly bears have died in Yellowstone this year, with humans responsible for 71% of deaths
- Deaths are on track to exceed last year’s record of 74 fatalities
- 85% of all grizzly deaths are linked to human interactions
- About 700 bears remain in the Greater Yellowstone Ecosystem
Grizzly bears in Yellowstone National Park are dying at alarming rates, with humans causing most fatalities. At least 63 bears have been killed this year, putting 2024 on pace to break last year’s record of 74 deaths.
Human Impact on Grizzly Mortality
According to the Interagency Grizzly Bear Study Team, 85% of grizzly deaths result from human interactions. This year, 45 of the 63 documented deaths (71%) involved humans through vehicle collisions, hunting accidents, and other conflicts.
The rising bear fatalities coincide with Yellowstone’s increasing visitor numbers. The park hosted over 4.7 million tourists in 2024 and expects another record year.
Legal Protection and Penalties
Grizzlies have been protected under the Endangered Species Act since 1975. Killing one is a federal crime that can bring fines up to $100,000, loss of hunting licenses, and jail time.
Chris Servheen, former FWS coordinator, noted: “There may be a few more bears, but mortality numbers can vary from year to year. The long-term numbers are what are important.”
He added: “Most grizzly deaths are due to humans every year,” warning that actual death counts are likely higher, especially with hunting season approaching.
Troubling Case of Food-Conditioned Bear
In one incident this year, rangers euthanized a 400-pound male bear that repeatedly broke into trash bins and overturned 800-pound dumpsters.
Yellowstone officials stated: “We go to great lengths to protect bears and prevent them from becoming conditioned to human food. But occasionally, a bear outsmarts us. When that happens, we sometimes have to remove the bear to protect visitors and property.”
With approximately 700 grizzlies remaining in the Greater Yellowstone Ecosystem, conservation efforts face ongoing challenges from human-bear conflicts.
