Orangutans are the world's largest arboreal mammals with sophisticated cognitive and social needs. Zoo management must provide environments that support their unique behavioural requirements.
Orangutans present significant welfare challenges in captivity. Their arboreal lifestyle requires three-dimensional space that most zoo facilities cannot adequately provide. Their intelligence and semi-solitary nature mean that boredom and inappropriate social housing are real welfare risks. Cognitive enrichment — foraging puzzles, novel materials, complex environments — must be extensive and varied to meet their needs. Welfare monitoring should include behavioural diversity, use of vertical space, and absence of stereotypic behaviours. Conservation education is essential: every visitor should understand the connection between their consumer choices and orangutan survival.
