Lee et al.: Maximum entropy modeling of farmland damage caused by the wild boar (Sus scrofa) -1101 -APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 16(2):1101-1117. Abstract. Farmland damage caused by wild boars was modeled by the Maxent model using the fieldinspecting data surveyed in Gyeongnam Province of South Korea during 2012 and 2013. A total of 3,854 cases (2,286 in 2012 and 1,568 in 2013) were chosen for the model after the field inspection. The Maxent model obtained quite high AUCs

The variable 'distance from forest boundary (d_forest)' revealed a higher probability for damaged areas located closer to forest boundaries. The areas damaged by wild boars were also located much closer to agricultural areas, including paddies and fields. Overall, areas located within 500 m of other agricultural areas showed a higher likelihood of damage by wild boars. Based on the predictions in Maxent, damage to farmland caused by wild boars was more closely related to distance from its habitat (i.e., forest) and use of land as food resources (i.e., rice paddies and fields) than topographical factors such as elevation and slope.
