To counter that risk, a robust Yellowstone population is critical for the species to establish itself along that corridor, said David Mattson, a former member of the Interagency Grizzly Bear Study Team who has researched Yellowstone's grizzlies for decades.
The GYE grizzly bear population is one of the best studied bear populations in the world thanks to the longstanding efforts of the Interagency Grizzly Bear Study Team (IGBST).
Biologists with the Interagency Grizzly Bear Study Team (IGBST) fitted eight Wyoming grizzlies with GPS collars last summer and followed their movements throughout hunting season.
Members of the Interagency Grizzly Bear Study team say in a new study that data collected on the threatened bruins over the past several decades contradict claims that the animals could be in serious trouble.

"Our population is strong, our counts of females are high," said Chuck Schwartz, a US Geological Survey scientist, who heads the Interagency Grizzly Bear Study Team.
"No other terrestrial mammal in North America has more demanding habitat requirements than the grizzly," says Chuck Schwartz, leader of the federal Interagency Grizzly Bear Study Team. Despite the continuing threats to its survival, the bear is being considered for delisting because of increased development pressure in Wyoming, Montana and Idaho.
Grizzly bears are five times more likely to die in an area with roads or trails, according to a 1991 study by Dave Mattson and Richard Knight of the Interagency Grizzly Bear Study Team. The researchers also determined that grizzly bears in the Greater Yellowstone Ecosystem tend to avoid habitat within 2.4 miles of a road.
The Individual Grizzly Bear Histories and Annual Reports of the Interagency Grizzly Bear Study Team databases (see Appendix A) explicitly distinguish between trappings done for management and research purposes.
The bear has a number for a name because he's been trapped by the Interagency Grizzly Bear Study Team, a brigade of federal and state bear biologists that has been radio-collaring and studying grizzlies in Yellowstone since 1975.
The new program comes at a critical time for Yellowstone grizzly bears, which in spring and fall feed almost exclusively on whitebark seeds, says Dave Mattson, a habitat specialist for the Interagency Grizzly Bear Study Team. Drought and the fires of 1988 wiped out up to 25 percent of Yellowstone's cone-producing trees, and a blister-rust epidemic would be a major catastrophic event here for the grizzly-bear population.
