The black rhinoceros is one of the world's most critically endangered large mammals. Conservation efforts including anti-poaching, dehorning, and translocation raise important animal welfare considerations alongside their conservation goals.
Conservation interventions for black rhinos involve significant welfare trade-offs. Dehorning requires chemical immobilisation — a stressful and not risk-free procedure — and must be repeated throughout the animal's life. Capture and translocation causes acute physiological stress: black rhinos in particular show high rates of "capture myopathy" — muscle damage from extreme stress responses — and mortality during transport. Intensive protection programmes mean rhinos live under constant human surveillance, which itself may cause low-level chronic stress. Poaching attacks that wound rather than kill cause extreme suffering to the surviving animal. The welfare costs of conservation interventions must be carefully weighed against the conservation benefits, and welfare outcomes should be systematically monitored.
