Rhinoceroses are critically endangered megaherbivores whose zoo populations serve as genetic reservoirs for wild conservation, requiring specialized habitat design and management for their specific behavioral and social needs.
Rhinoceros welfare in zoo settings requires understanding the behavioral ecology of each species — the social black rhino differs substantially from the more social white rhino in management requirements. White rhinos in well-designed zoo environments with appropriate social groupings show reasonable behavioral welfare indicators, while black rhinos require more careful territorial management. The welfare significance of dehorning — performed in wild and sometimes zoo populations to deter poachers — deserves attention: the horn is used in social interactions, digging, and defense, and its removal represents a loss of functional behavioral capacity. The urgent conservation situation for rhinoceros species gives zoo welfare investment particular importance — well-managed zoo populations are the last resort for species where wild populations face extinction risk.
