Human-wolf-livestock coexistence efforts in Washington rely on sustaining wolves' fear of people, often described as "innate" even as it is reproduced through human-wolf interactions.• Mitigating wolf-livestock conflict requires managing human social norms, values, and assumptions about wolf behaviour that are interwoven with ecological fear dynamics. • Interdisciplinary dialogue between the social and biophysical sciences, inspired by critical physical geography, can enhance the study of socioecological processes, including human-wildlife conflict dynamics.Animal fear can be an important driver of ecological community structure: predators affect prey not only through predation, but also by inducing changes in behaviour and distribution-a phenomenon evocatively called the "ecology of fear." The return of wolves to the western United States is a notable instance of such dynamics, yet plays out in a complex socioecological system where efforts to mitigate impacts on livestock rely on manipulating wolves' fear of people. Examining Washington state's efforts to affect wolf behaviour to reduce livestock predation, we argue that this approach to coexistence with wolves is predicated on relations of fear: people, livestock, and wolves can arguably share landscapes with minimal conflict, as long as wolves are adequately afraid. We introduce the "socioecology of fear" as an interdisciplinary framework for examining the interwoven social and ecological processes of human-wildlife conflict management. Beyond frequently voiced ideas about wolves' "innate" fear, we examine how fear is (re)produced through human-wolf interactions and deeply shaped by human social processes. We contribute to the critical physical geography project by integrating critical social analysis with ecological theory, conducted through collaborative interdisciplinary dialogue. Such integrative practice is essential for understanding the complex challenges of managing wildlife in the Anthropocene.
