Managers from the state, tribal, and federal agencies responsible for recovery of the grizzly bear in the Yellowstone Ecosystem heard good news at their recent meeting in Bozeman, Montana.  Despite being a poor cone production year for the already beleaguered whitebark pine trees, managers heard reports of surprisingly few conflicts between humans and grizzly bears, even though a record count of 58 unduplicated females with cubs were observed in the ecosystem this year.  Especially promising was that a female with cub was documented in each of the 18 bear management units used to keep track of the bear population.

In addition to reports of minimal conflicts from all of the states and national parks, managers also heard a report on the annual population status from the Interagency Grizzly Bear Study Team. Utilizing existing statistical  methods the population estimate for the Yellowstone Ecosystem in 2013 is 629. Idaho Fish and Game Spokesman, Greg Losinski: "Our extensive analysis of existing research and monitoring has shown us that grizzly bears are resilient and resourceful in the face of changing food resources. Our findings indicate that the decline in whitebark pine trees due mostly to mountain pine beetles is not a major threat to the future of  the Yellowstone grizzly bear population. Data show the observed slowing of population growth since 2002 is  a result of  increased grizzly bear population density and resulting declines in subadult survival."
