To date, there is no systematic research on the overlapping challenges of wildlife conservation and security in South Sudan, where the wildlife service (WLS) has institutionally survived for over a century while contending with poor state capacity and responsibility for protected areas (PAs) that cover vast territories characterized by chronic insecurity and food scarcity. Integrated into the country’s “Organized Forces,” South Sudan’s park rangers play roles beyond conservation as armed actors in complex conflicts. Data obtained from archival research and field interviews shows that South Sudan’s wildlife authorities have persisted since the colonial period in spite and because of chronic warfare.
