The grizzly bear delisting saga continues . . .
Grizzly bears in the greater Yellowstone ecosystem have a varied diet and are minimally affected by the decline in the number of whitebark pine trees, federal research found.
The findings were presented Thursday in Bozeman at a meeting of the Yellowstone Ecosystem Subcommittee of the Interagency Grizzly Bear Committee. The subcommittee voted 10-4 to accept the research findings. It also gave preliminary approval to a motion that recommends the U.S. Fish and Wildlife Service remove federal protections for the bears, currently listed as “threatened.”
The USFWS delisted the bears in 2007, but a federal judge returned the protection two years later, saying the effect of the decline in whitebark pine trees on bears wasn’t given adequate consideration. Whitebark pine nuts are a key food source for grizzlies as they prepare for hibernation.
Research found that grizzly bears eat more than 200 types of food, 75 of them frequently. That means when one food source is low, as the whitebark pine is, they find another, said Frank van Manen, interagency study team leader.
