Public acceptability of measures to prevent from predation on commercial fish by the endangered Eurasian otter (Lutra lutra) in Natura 2000

Abstract The influence of humans on aquatic habitats, along with extensive hunting, has caused a decrease in the population of the Eurasian otter ( Lutra lutra ) in Central Europe. Although, in recent decades, the status of otters has improved as a result of conservation efforts. However, their increasing numbers have led to increased human-animal conflict (damage from predation on commercial fish). It is necessary to take continuing conservation measures to maintain the otter population and mitigate human-otter conflict. The purpose of this study was to identify attitude dimensions in Goricko Landscape Park (GLP) Slovenia that affect the acceptability of measures for otter management and to identify the differences in attitudes among different groups of GLP residents. Understanding the public perception of otters will provide wildlife managers a better understanding of the public attitude towards these animals and towards the acceptability of measures for otter management, an understanding on which they can prepare management decisions and education programmes. A research model from variables in a survey was tested with Structural Equation Modeling and ordinal regression analysis. The acceptability of measures was influenced by various attitudes--scientistic, moralistic and naturalistic--in interaction with two moderator variables: living in the Natura 2000 conservation area; and, having a business connection with fish breeding. Most residents have a positive attitude towards otters; therefore, conservation should not be a problem. Those who have a business connection with fish breeding should be educated about feasible and effective measures for otter management, to be able to act appropriately in this type of conflict involving the endangered otter species and the prevention of economic damage.
