The Mount Kei Forest Reserve is a former white rhinoceros sanctuary along the Uganda-South Sudan Border. It covers parts of Yumbe and Koboko districts in North Western Uganda and is bordered by Lynia County on the South Sudan side. The forest reserve lost its rhino population and much of its the wildlife to poaching, and the Uganda Wildlife Authority has since handed management to the National Forestry Authority. While the reserve remains a rich biodiversity habitat, cross-border criminals roam its boundaries and evade law enforcement, and opportunist farmers till its land.
