The Save the Rhino Trust (SRT) has launched an internal investigation after it was presented with a letter in mid-December outlining possible collusion between some staff members and poachers who have killed at least 18 critically endangered Kunene black rhinos since late 2012. The crisis at the SRT is however just part of a larger one in anti-poaching law enforcement and natural resource management in the so-called “Big Three” communal conservancies - Palmwag, Abenab and Sesfontein - in southern Kunene.
