Wild Pig Resource Selection in an Agro-Forested Landscape of Southwestern Georgia, USA

Sus scrofa L. (Wild Pig) are invasive, found throughout much of the US, and annually cause $1.5–2.2 billion in damage to natural and agricultural resources. Understanding habitat selection by Wild Pigs may inform control efforts by allowing managers to target their removal in frequently used habitats. Therefore, we used GPS tracking collars to study resource selection by Wild Pigs within their home ranges in an agro-forested landscape in southwestern Georgia, USA, during 2021–2023. Both sexes showed a greater probability of selecting areas near forested wetlands/riparian zones during both seasons, making this the most consistently selected landcover type. During the growing season (May–October), female Wild Pigs also showed a greater probability of selecting areas near unpaved roads but a lower probability of selecting areas near upland forests; during the dormant season (November–April), they showed a greater probability of selecting areas near upland forests and paved roads but a lower probability of selecting areas near unpaved roads, cropland, and buildings. In addition to forested wetlands/riparian zones, males showed a greater probability of selecting areas near cropland and buildings during the growing season; during the dormant season, they showed a greater probability of selecting areas near buildings and unpaved roads. Males showed a lower probability of selecting areas near paved roads during both seasons. During the growing season when Wild Pig damage to crops can be severe, Wild Pigs used cropland most often in the morning crepuscular hours. In an agro-forested landscape, efforts to remove Wild Pigs should prioritize forested wetlands and riparian zones year-round, while also targeting croplands specifically during the growing season. Removal of Wild Pigs from croplands may be male biased because males, but not females, selected crops during the growing season. Efforts to control Wild Pigs during the growing season may also reinforce fear of humans, resulting in decreased selection by Wild Pigs and subsequent declines in crop damage.
