OR7: In 2009, a male wolf was born into northeastern Oregon’s Imnaha Pack and later collared by ODFW in February 2011. In September 2011, OR7 dispersed from his pack and crossed into Siskiyou County in December 2011. In 2012 and part of 2013, he traveled through Butte, Lassen, Modoc, Plumas, Shasta, Siskiyou, and Tehama counties before returning to Oregon in April 2013. He made several brief visits back to California in the fall of 2013 and early 2014 before settling down with a female wolf in southwest Oregon in the spring of 2014 to form the Rogue Pack. Several of his offspring have been detected in California over the years. They include CA08M/LAS02M (the original breeding male of the Lassen Pack), CA10F (a female detected in 2017 in eastern Siskiyou County who was a sister to CA08/LAS02M), OR54, who was likely born into the Rogue Pack in 2016, and YOW01F (the founding breeding female of the Yowlumni Pack). ODFW reported OR7’s absence from the Rogue Pack in late 2019 and has suggested that by spring of 2020, he had likely died. His mate from the Rogue Pack was found dead of natural causes in Oregon in February of 2021.
CA10F: A female wolf who was tracked in eastern Siskiyou County about 20 miles from the Oregon border in January 2017. Genetic analysis of her scat determined she was born into the Rogue Pack in Oregon in 2014 and is a littermate of CA08M, the breeding male of the Lassen Pack. Her current location is unknown.
OR25: A male wolf who was radio-collared in Oregon by ODFW in May 2014 and dispersed from the Imnaha Pack in March 2015. During his dispersal, OR25 traveled through the Columbia Basin, Southern Blue Mountains, and Northern and Central Cascade Mountains. Beginning at the end of May 2015, he used an area in the Sprague and Silver Lake Units in Klamath County, Oregon. Starting in mid-December 2015 and on into spring of 2016, OR25 crossed the border repeatedly into California, spending some of his time in Klamath County in Oregon, and other times roaming within California’s Modoc and Lassen Counties. In October 2017, OR25 was found illegally killed by gunshot near Fort Klamath, Oregon. A law enforcement investigation into his death remains open and the case unsolved.
OR54: A female wolf wearing an Oregon tracking collar, she crossed into eastern Siskiyou County in January 2018. She was born into the Rogue Pack, likely in 2016. She went back to Oregon twice, visited Nevada once, toured at least 9 California counties and traveled at least 8,712 total miles! She was known as a disperser, searching but not settling. Sadly, her body was found on February 5, 2020 in Shasta County, CA. Her cause of death has never been made public by CDFW, but her death is under investigation by wildlife officials.
OR44: A male, born into Oregon’s Chesnimnus Pack in 2016. He was fitted with a satellite collar by ODFW in December 2016 and dispersed from his pack in fall 2017. He crossed the Oregon border into eastern Siskiyou County in March 2018. His collar failed in May 2018, while he was in Siskiyou County. His current location is unknown.
OR59: A young (1.5 year) male wolf, who entered Modoc County from Oregon in December 2018. A week later, Oregon wildlife officers notified CDFW that OR-59’s collar was emitting a mortality signal; he was found dead by gunshot shortly thereafter. His death is currently the subject of a criminal investigation.
OR93: Born in 2019 to the White River Pack, whose territory partly includes reservation lands of the Warm Springs Indian Tribe, southeast of Portland, OR93 was collared by tribal biologists in June 2020. Soon after, he dispersed southward towards California. In January of 2021, he entered Modoc County, briefly returned to Oregon, then re-entered Modoc County before travelling through Lassen, Plumas, Sierra, Nevada, Placer, El Dorado, Amador, and Calaveras counties before entering Alpine County. Continuing his journey, OR93 entered Mono County later in February. In March, he was observed in western Tuolomne County, Fresno County, then San Benito County after crossing Highway 99 and I-5. In early April, he was in Monterey County and San Luis Obispo County before his last collar transmission on April 5. In mid-May, a trail camera in Kern County detected a wolf likely to be OR93, and in late September there were eyewitness sightings of a wolf that appeared to be OR93 in northern Ventura County. OR93 was found dead on November 10, 2021, near the town of Lebec in Kern County. Evidence indicated he died from a vehicle strike. When his collar stopped transmitting on April 5, he had traveled at least 935 air miles in California, a minimum average of 16 air miles per day.
OR103: OR103, a wolf born in 2019 or 2020, entered northeastern Siskiyou County on May 4, 2021. Except for a brief foray into northern Trinity County in early March 2022, he remained in Siskiyou County until early July 2022, when he returned to Oregon. OR103 was collared by ODFW in Deschutes County, Oregon. OR103 was illegally killed near Upper Klamath Lake, OR in October 2022 and his pack origin remains unknown. In late 2024, a male wolf was identified through genetic analysis in Lassen County along with LAS32F. This male’s genetic profile suggests that he is a sibling (subsequent litter) of OR103. In October of 2022, OR103 was found illegally killed near Klamath Falls, Oregon, and his death remains under investigation by law enforcement officials.
OR158: OR158, a male wolf who was collared in Baker County, Oregon while traveling alone, briefly entered California in December 2024. OR158 spent only a week in Modoc County, before returning north to Oregon. In February of 2025, OR158 was killed by federal agency staff following his involvement in multiple livestock conflicts.
BEY10M: A male wolf from the Beyem Seyo Pack who dispersed into Lassen County in early 2025.
Uncollared black wolf: An unknown black wolf was photographed by private trail cameras in northern Lassen County and in southern Modoc County in April 2018. Likely the same wolf was then photographed in by another private trail camera in northern Lassen County in both August and September 2018. In September, CDFW observed what appeared to be wolf tracks nearby in southern Modoc County. CDFW is working to obtain further info on this wolf.
Additional uncollared wolves: Uncollared dispersing wolves have been detected since 2011. Most of the detections have occurred in Modoc, Lassen, Plumas, and Siskiyou counties.
Detections include:
- DIS01F (Siskiyou County, January 2017): a female wolf from the Rogue Pack, confirmed by DNA analysis
- DIS02M (Lassen County, October 2017): a male wolf from Oregon’s Meacham Pack, confirmed by DNA analysis
- DISO3M (Modoc County, May 2020): a male wolf related to Oregon’s former Walla Walla Pack, confirmed by DNA analysis
- DIS04M (Lassen County, October 2024): a male related to OR103, confirmed by DNA analysis
- DIS05M (Southern Plumas County, spring 2025): an unknown male wolf confirmed by genetic analysis
