The Harl Butte wolf pack killed a calf and injured another in attacks investigated by Oregon Department of Fish and Wildlife Sept. 29 and Oct. 1.
ODFW shot four pack members in August in what it described as an incremental response to repeated depredations.
Cattle ranchers in the area predicted the department’s response wouldn’t work and now are likely to renew their call to have the entire pack killed. ODFW has confirmed 10 attacks on cattle by the pack since July 2016, all within nine miles of each other. As of Oct. 4, ODFW had not announced how it will respond to the latest attacks. Even with four killed in August, the pack is thought to consist of six adults and three pups, according to ODFW reports.
On the morning of Sept. 29, a volunteer range rider found a dead 425-pound calf on private grazing land in the Marr Flat area of Wallowa County. An estimated 40 percent of the carcass had been consumed, according to an ODFW report. Tracking collar data showed a wolf designated OR-50, the only pack member wearing a collar, was at the carcass about 90 minutes before the range rider found it.
The injured calf found Oct. 1 had a large open wound on the inside of its upper left rear leg, according to ODFW, which estimated it had been attacked Sept. 25. The calf weighed 570 pounds.
The attack also happened on private land in the Marr Flat area. OR-50 was in the area Sept. 23-25, according to ODFW.
