Translocation of black rhinos between populations is essential for genetic management, but carries significant welfare risks from capture, transport and release stress.
Rhino capture with M99 (etorphine) requires precise dosing and rapid reversal to minimise physiological stress. Capture myopathy — fatal muscle breakdown from exertion — is a documented risk in stressed animals. Transport in crates causes claustrophobic stress for large territorial animals. Release into unfamiliar habitat requires careful site preparation to reduce territorial conflict with established animals. Despite these welfare costs, translocation is a net benefit for population welfare compared to genetic isolation.
