This information is useful in identifying regions at greatest risk if wild pigs become established, which can assist in prioritizing management actions aimed at controlling or eliminating this invasive species across broad to local scales.Īnderson A, Slootmaker C, Harper E et al (2016) Economic estimates of feral swine damage and control in 11 US states. Regions in the western, northern, and northeastern United States contain no or few wild pig populations, but could potentially support large numbers of these animals if their populations become established. We demonstrate which states have experienced recent population growth of wild pigs and are predicted to experience the greatest population increase in the future without sufficient management actions and policy implementation. In addition, we estimated potential population size if wild pigs were present at equilibrium conditions in all available habitat in each state. We intersected these two data sets to estimate the population size of wild pigs in 1982, 1988, 2004, 2010, 2013, and 2016. In addition, recent research has predicted potential population density of wild pigs across the United States by evaluating broad-scale landscape characteristics. Between 1982 to present, the Southeastern Cooperative Wildlife Disease Study mapped the distribution of wild pigs in the United States. We used two national-scale data sets to estimate historical, current, and future potential population size of invasive wild pigs ( Sus scrofa hereafter wild pigs) in the United States. This information is critical for informing management actions and allocating resources. To control invasive species and prioritize limited resources, managers need information about population size to evaluate the current state of the problem, the trend in population growth through time, and to understand the potential magnitude of the problem in the absence of management actions.
