A descriptive study of poisoners and users of other indiscriminate means to illegally control wildlife in Spain

Abstract

Abstract Poison and other indiscriminate means are used illegally for wildlife control worldwide. This pervasive phenomenon can significantly damage ecosystems overall and be particularly harmful to certain species (endangered or otherwise) that are susceptible to poisoned baits. Poisoning (and co‐occurring poaching) jeopardizes public administration efforts to reintroduce or support the populations of certain species, while the favored toxic substances used pose a major threat not only to the biodiversity of habitats but also to human health. Both alleged and actual harm to crops and hunting resources are the main driver of illegal vermin and predator control. Previous studies on poisons and other nonselective methods of wildlife elimination have focused on the means used and the species affected. We have instead taken a global empirical approach, also analyzing contextual aspects, what motivates perpetrators and, eventually, the characteristics of the poisoners and users of various indiscriminate means for illegal wildlife control in Spain. This analysis is derived from a thorough examination of incidents based on the investigation of perpetrator by police and judicial records. Furthermore, this work provides a methodological framework that serves as first approach to this issue, gaining insight into the formulation of preventive policies and improving decision taking by law enforcement agencies.
