From Removal to Selective Control: Perspectives on Predation Management in Spanish Hunting Grounds

Historically, predator control has been a frequent practice conducted in the hunting grounds of Spain. After the approval of Law 42/2007 on Natural Heritage and Biodiversity, and the enforcement of international regulations, predator control methods are required to be selective, non-massive, and conducted by trained specialists when traps are used; however, there is a lack of research on the current status of predator management. Data was gathered from 16 regional wildlife departments and from 373 questionnaires from hunting grounds targeting the conservation of small game species. Seven predatory species were included in the regional game species lists, the most frequently controlled being the red fox (Vulpes vulpes, 90.4%), wild boar (Sus scrofa, 78.3%), and Eurasian magpie (Pica pica, 51.5%), with control intensity differing among regions. In total, 87% of the questionnaire respondents declared controlling at least one predator species, while 49.3% employed gamekeepers to perform the control. In all surveyed regions, shooting was authorized, and it was the most frequent control method in hunting grounds for the aforementioned species (ranging from 76 to 100%), while the use of approved restraint methods was allowed in 11 regions but only used in 7 for foxes (8%) and magpies (25%). The control intensity (animals culled/km²) for foxes was higher when conducted by full-time keepers, while for magpies and wild boars, it was higher when conducted by hunters. The implementation of habitat management (agricultural and forest measures) that helps to reduce predation was higher in hunting grounds not conducting predator control. Based on our results, we propose a national predation management framework focused on controlling rather than removing predators.
