CHEYENNE, Wyo. (AP) — The Wyoming Game and Fish Department says it documented more problems with grizzly bears last year compared to the year before.

Most conflicts occurred around Pinedale and Cody and the vast majority involved livestock. Game and Fish says it recorded 164 conflicts between grizzlies and people and human-related activities last year, up from 152 in 2013.

Brian DeBolt of the agency's wildlife division told the state Game and Fish Commission Thursday that grizzly bears continue to expand their range. More are found in the southern Wind River Range, the Wyoming Range and the Bighorn Basin.

The U.S. Fish and Wildlife Service is expected to decide this year whether it will move to lift protections for some 1,000 grizzlies scientists say live in the Yellowstone region of Montana, Idaho and Wyoming.
