Sylvain CORDIER/Gamma-Rapho via Getty Images The Oregon Department of Fish and Wildlife killed two wolf pups from a helicopter Sunday following "chronic" cattle depredation in eastern Oregon. "We want to see the pack persist and endure in this area, but we have a responsibility to address this chronic depredation," Oregon Fish and Wildlife spokesperson Michelle Dennehy told SFGATE. Dennehy said the Lookout Mountain wolf pack killed four cows and injured one calf in a 14-day period in July, which qualifies as chronic depredation. On July 29, Fish and Wildlife approved a kill permit that enabled the livestock producer to kill up to four un-collared wolves within a designated area.
