: Human-wildlife conflict is one of the most serious threats to many wildlife species. Therefore, it is important to identify factors affecting the conflict for conservation purposes. The purpose of this study was to investigate local people's attitudes toward striped hyena and the causes of conflicts between people and hyenas of Dezful County. The study was conducted in 19 villages by 330 structured interviews to explore the influence of factors such as age, gender, hateness toward hyena, education, and knowledge on people's conservation and superstitious attitudes towards hyenas. Gender, age and education influenced the superstitious attitude of interviewees. Superstitious attitude toward hyena were more common among women and older people than men and younger ones. In addition, people with higher education had lower superstitious attitude. Interviews with local people revealed that hyena in the study area did not damage crops, but livestock (sheep and goats). Having good knowledge about the hyena had a positive impact and the experience of livestock depredation by hyenas had a negative effect on their conservation attitude.The occupation of 37% of the interviewees was livestock herding. Less than a half of the herders used predator proof corral pens to protect their livestock from predators attack. It was while; nearly all the herders who had experienced livestock depredation have not used such corral pens. Hence, training local people to establish predator proof corral pens could mitigate human-hyena conflict in the study area.
