Wolf found dead in California was OR-7 progeny

An endangered gray wolf that was found dead Wednesday in Northern California was a daughter of OR-7 that had been collared in Oregon in 2017 to help gather evidence of the Rogue Pack’s livestock kills before she lit out on her own in 2018.

The wolf, OR-54, who was the 54th gray wolf fitted with a GPS-transmitting collar, was found dead Wednesday in Shasta County. It wasn’t immediately made clear by California wildlife officials whether she died of natural causes or was killed.

The wolf was estimated to have been born in 2016, and she was trapped and fitted with the GPS collar Oct. 3, 2017, in western Klamath County in the hopes that she would help state and federal biologists track the whereabouts of the Rogue Pack.

The pack was suspected of numerous attacks on livestock in northeastern Jackson County, which is the heart of the pack’s home range, according to the Oregon Department of Fish and Wildlife.

Her collar’s GPS readings helped document three livestock kills at Ted Birdseye’s Butte Falls-area ranch during the first two weeks of January 2018, before she apparently split from the pack.

After she dispersed from the Rogue Pack, she crossed into California Jan. 23, 2018, and toggled between Oregon and California several times after that, according to ODFW data.

She also briefly entered Nevada in 2019 and roamed more than 8,700 miles throughout much of northeastern California last year, according to data from the California Department of Fish and Wildlife.

OR-54’s GPS collar put her on the site of several livestock killings in California’s Plumas County last year, according to California authorities.

In Oregon, state and federal biologists have been unable to trap and collar a Rogue Pack wolf since OR-54 left the area.

Wolves throughout California and all of western and southeastern Oregon are protected as endangered species under the Federal Endangered Species Act.
