Laramie, WY – Grizzly bears in the region in and around Yellowstone National Park have suffered unusually high mortality rates so far this year.
Interagency Grizzly Bear Study Team leader Chuck Schwartz says a dearth of food is most likely to be the cause.
Schwartz says officials tallied 25 known and probable grizzly mortalities. Twenty-two of those mortalities were human-caused, two of the deaths resulted from natural causes, and the cause of one death was undetermined.
For every bear that was reported dead, Schwartz says two more deaths likely went unreported.
Schwartz spoke to a group of wildlife managers and conservationists at the annual meeting of the Yellowstone Grizzly Coordinating Committee at Jackson.
