Wild boar battues reduce crop damages in a protected area

Abstract

Agricultural damages caused by wild boar Sus scrofa have given farmers a negative impression of protected areas and their management. To mitigate those damages and the social conflicts that they create, hunting battues involving experienced local hunters were used as a lethal population control method in a protected Iberian wetland. In the Ebro Sotos and Galachos Nature Reserve, Spain, between 1994 and 2011, 259 wild boars were culled during 476 battues. On average, battues involved six hunters and ten dogs, and culling efficiency (number of animals killed per animals seen during battues) was 39 %. The number of battues per year and the area of crop damages caused by wild boar were significantly negatively correlated, demonstrating battue efficiency to decrease damages. Moreover, intermittent population control through culling led to a substantial increase in the wild boar population, with an increase in crop damages. This underlines the importance of constant control. The numbers of hunters and dogs and the number of wild boar seen during battues were strongly correlated. To minimize the conflicts between farmers and the management of protected areas, we suggest that the inexpensive, volunteer-based population control program could be enhanced by incorporating stalking and mobile electric fences.
