The brown bear population in Yellowstone National Park is part of the Greater Yellowstone Ecosystem (GYE) population, which has seen significant recovery over the past few decades. As of recent estimates, the GYE is home to approximately 1,063 grizzly bears. Within Yellowstone National Park itself, about 150-200 of these bears have home ranges that overlap with the park boundaries.

This remarkable recovery is a testament to the conservation efforts that have been in place since grizzlies were listed as threatened under the Endangered Species Act in 1975. At that time, the population had dwindled to just 136 bears. Today, the population has stabilized and is considered to be at or near the ecosystem’s carrying capacity.

For visitors to Yellowstone, this means there is a higher likelihood of encountering these magnificent animals, making it all the more important to respect their space and follow park guidelines to ensure both human and bear safety.
