All five rhinoceros species face extinction pressures. Their captive management plays a conservation role, but welfare challenges related to social housing and space must be carefully addressed.
Rhinoceros welfare in zoos is shaped by species-specific social requirements that differ markedly between white and black rhinos. White rhinos can be socially housed in compatible groups; black rhinos are more solitary and territorial. Aggressive encounters between incompatible individuals cause injury and chronic stress. Substrate management is critical — hard concrete floors cause foot pathology that can become life-threatening. The extraordinary conservation situation of the northern white rhino — where captive individuals may be the last hope for the species through assisted reproduction — adds unique pressure to captive management programmes. For all rhino species, field protection through anti-poaching investment remains the most cost-effective conservation strategy.
