SIERRA VALLEY, CA – California wildlife officials announced Friday they euthanized four gray wolves from the Beyem Seyo pack following an unprecedented surge in livestock attacks that killed 70 animals in Northern California’s Sierra Valley region over a six-month period.
The decision came after extensive efforts to break the wolves’ pattern of targeting cattle proved unsuccessful, according to the California Department of Fish and Wildlife. Between late March and early September, the four wolves were responsible for nearly two-thirds of all wolf-related livestock deaths in California during that timeframe.
Despite deploying various non-lethal deterrents including noise makers, protective flagging around grazing areas, and vehicle-based herd protection, wildlife officials could not stop the attacks. The wolves had become so dependent on cattle for food that breaking the cycle became impossible.
“We could not break the cycle, which ultimately is not good for the long-term recovery of wolves or for people,” said CDFW Director Charlton Bonham in a statement explaining the difficult decision.
The Beyem Seyo pack’s behavior represented an unusual pattern in California’s growing wolf population. Wildlife officials determined that euthanization was necessary to prevent further livestock losses and protect the broader recovery effort for gray wolves in the state.
Gray wolves were nearly eradicated from California by the 1920s but have been making a comeback in recent years. The state now hosts 10 confirmed wolf packs, all of which naturally dispersed from Oregon populations as part of the species’ broader recovery across the Western United States.
The wolf resurgence has sparked ongoing tensions between conservation advocates who celebrate the species’ return and rural ranchers who face significant economic losses when wolves target their livestock. Similar conflicts have emerged in other states that have seen wolf populations rebound.
Wildlife officials emphasized that the euthanization decision was made only after all non-lethal options were exhausted. The removal of the four wolves aims to protect both the remaining wolf population’s reputation and the livelihoods of Sierra Valley ranchers.
California continues to monitor its wolf packs as the species establishes itself in new territories across the state. Officials say they remain committed to both wolf recovery and protecting agricultural interests through science-based management decisions.
