(JACKSON, Wyo.) – Wildlife biologists are unsure as to what might be causing an abnormally high amount of grizzly bear deaths in Yellowstone National Park this summer. Officials say that at least 10 of the 16 deaths came from natural causes. A major increase in grizzly deaths could have an impact on future policies. They say the natural aging of the overall bear population could be a factor. They plan to continue to assess the mortality trends until the final total at the end of the year.
