California’s Wolves

OR-7, affectionately named “Journey”, was the first confirmed wolf in California since 1924. He traveled over 4,000 miles back and forth from California to Oregon in 2012-13 and has since sired five litters in the Rogue-Siskiyou National Forest. At least three of OR-7’s pups and two of his siblings have been documented in California.


The Lassen Pack is California’s second confirmed wolf pack. Their territory lies within Lassen and Plumas counties. The alpha male (CA08M) was born into the Rouge Pack in 2014, sired by OR-7. The alpha female (LAS01F) was collared in June of 2017. The pair has had two litters and currently consists of two yearlings and five pups.


OR-54 was born into the Rogue Pack, likely in 2016. She was 83 pounds when collared in October 2017. In early 2018 the young female traveled over 500 miles through four counties in one month before retuning to Oregon. She returned to California in April 2018, traveling through six counties and spent most of her summer near the Sierra Valley. By January 2019, OR-54 had traveled over 4,325 miles.


The Shasta Pack was the first contemporary wolf pack in California. The alpha female was the younger sister of OR-7. The all black pack occupied a portion of Siskiyou County and produced five pups in spring 2015. The family was last seen together in late 2015. There were no sightings until May 2016, when a solo yearling male (CA07M) was detected near pup-rearing sites used in 2015. He is thought to be the only know survivor from the pack. In November 2016, CA07M was the first wolf to return to Nevada in nearly 100 years. While it’s believed the pack no longer exists, some evidence suggests at least one wolf was roaming within the Shasta Pack territory in 2017.


OR-44 was born into Oregon’s Chesnimnus Pack in 2016 and was collared in December that year. He entered CA in March 2018 into Siskiyou County where he was last located due to his collar failing. His current whereabouts are unknown.


CA10F is a female wolf born into the Rouge Pack in 2014. She is a sister to the alpha male of the Lassen Pack. She was tracked moving southeast through Siskiyou County in January 2017. She has no collar and her current whereabouts are unknown.


R.I.P — OR-59, a 1.5-year-old male, entered California on September 29, 2018. On December 5, in Lassen County, he was detected in the vicinity of a dead calf that had died of natural causes. On December 9th his collar sent a mortality signal and he was found dead. The action is now under criminal investigation.


R.I.P — OR-25, was a full brother to OR-7. He traveled through Washington’s Columbia Basin, Mt. Hood National Forest and down the length of the Oregon Cascades. In late 2015 and early 2016, he made four separate trips to California, where he roamed Modoc, Lassen, Shasta and Siskiyou counties. In late October 2017, at four years old, he was killed illegally in Klamath County, Oregon.


R.I.P — An uncollared wolf was found dead in Lassen County on September 5, 2018. The mortality is under investigation.


Wolves need your help! The U.S. Fish and Wildlife Service is proposing to remove wolves from the federal Endangered Species Act across the continental United States. The comment deadline for wolf delisting is May 14th 2019. Act now to defend wolves across the country! Click here to sign the petition.
