Species are often viewed as either beneficial or detrimental. The determination of beneficial or detrimental depends on the evaluator, often with disagreement within disciplines such as agriculture or wildlife biology. One common argument against a species revolves around its status as native or non-native, with the latter as a negative characteristic. Defining native and non-native is highly subjective, with a common North American delineation as an introduction before and after Columbus, respectively (Nelson 2010). However, in the past, native species such as the American buffalo (Bison bison) have been targets of eradication campaigns and even today white-tailed deer (Odocoileus virginianus) and Canadian geese (Branta Canadensis) populations are managed to limit the damage they inflict on agriculture. It is also acknowledged that these example species have intrinsic value in the ecosystem and value as a recreationally hunted species in the case of white-tailed deer and Canadian geese. Non-native species can be viewed beneficially, as most agricultural species are introduced, for recreational use, and even as a replacement for extirpated native species (Schlaepfer, Sax and Olden 2011; Zivin, Hueth and Zilberman 2000). In the US, one contentious species is feral swine (Sus scrofa). Federal removal and control efforts are underway as some private landowners encourage their growth on their property (Bevins et al. 2014; Bannerman and Cole 2014). Feral swine are a vector for diseases, cause ecosystem damage, and inflict physical losses to agriculture (Pimentel, Zuniga and Morrison 2005; Cozzens 2010; Seward et al. 2004). However, feral swine are a valuable recreational species. With benefits and costs often accruing to different people, conflict over management is inevitable. As in most externality problems, property lines do not inhibit damage. Unique to most externality problems is the way the damage causing agent can multiply and spread unaided once introduced. Stakeholders include agricultural landowners, ...
