A year ago, there were 122 wolves in 22 packs with 14 breeding pairs. The state's census numbers were compiled from state, tribal, and federal wildlife specialists based on aerial surveys, remote cameras, wolf tracks and signals from radio-collared wolves. The upturn in new packs and breeding pairs sets the stage for more growth this year, said Donny Martorello, policy lead for the agency. "Packs and breeding pairs are the building blocks of population growth," Martorello said. Maletzke said five of the 27 packs in Washington last year were involved in at least one livestock death.
