Local opposition to large carnivores is a frequent source of conflict and a major obstacle for large carnivore conservation worldwide. The aim of our study is to understand hunters' reasons for opposing large carnivores, paying particular attention to the social dimension of the conflict. In an area where a vigorous conflict about lynx (Lynx lynx) exists without there actually being individuals of this species resident, we conducted group discussions with hunters, a group that includes many lynx opponents. Results were interpreted using the theories of social identity and psychological reactance. We found that, despite the absence of large carnivores, hunters' perceptions and reasoning resembled those present in areas with resident large carnivores. This underlines the significance of the social dimension. Results show that the hunters' position in the lynx conflict is shaped by past experiences with pro-lynx groups (forestry and nature conservation). In this interaction, hunters see their social identity as being threatened which in turn leads to group discrimination and reactance processes — the latter possibly resulting in illegal shootings of lynx. Thus, hunters' opposition is not solely about the impacts of the lynx, but also about defending their social identity and withstanding impairment of their perceived freedoms by other interest groups. We argue that actively dealing with such group dynamics could serve as a missing link between large carnivore protection and conflict management. Future large carnivore management should focus more on shaping the quality of the interaction between the managers, advocates and opponents of large carnivores in order to overcome group-conflict and reactance processes.
