Abstract Recovered and recovering carnivore populations in Europe and North America can pose risks to some human livelihoods like livestock ranching. These risks can motivate wildlife managers to lethally remove carnivores—decisions that are often controversial and poorly understood. We used a 13-year dataset on gray wolves (Canis lupus) in the northwestern United States (Montana, Idaho, Washington, and Oregon) to analyze how social, demographic, and environmental variables influence lethal removal of wolves at the county and state levels. We found that state-level differences are a major driver of lethal removal decisions at the county level. The percentage of federally owned and protected lands was also positively correlated with lethal removal. Predation of livestock by wolves was not significantly correlated with wolf removals in Idaho, but was in Montana, Washington, and Oregon. Our results stress the need to make transparent the process by which recovering populations of carnivores are managed to enhance the legitimacy of management policies.
