However, South African success at large predator reintroduction is largely the result of ubiquitous fencing that generally prevents predator conflict with people and livestock (see Gusset et al. 2008).enAmerican Institute of Biological SciencesFencesProtected areasWildlife refugesPredatory animalsArticle
