The Umatilla Pack in Northeastern Oregon is blamed for a pair of livestock attacks earlier this month.
On June 11, a cattle rancher discovered an injured cow in a timbered pasture on private land. The cow has multiple bites from what an Oregon Department of Fish and Wildlife investigator described as a large carnivore.
On June 13, less than a mile away, seven penned sheep were killed, five others were injured and one went missing in an early morning attack.
Data from a radio collar indicated that at least one Umatilla Pack wolf, OR-14, was in the area at the time of the attack. Sheep in the same pen were attacked in 2012, as well.
The attack sites are near Wildhorse Road in rural Umatilla County.
The 2013 Oregon wolf survey indicated the state had at least 64 wolves in eight known packs. Since the survey results were released, the wandering wolf known as OR-7 has found a mate in Southern Oregon and the pair have at least two pups.
Wolves are protected under the federal and state Endangered Species Acts.
