Sumatran tigers are Critically Endangered with fewer than 400 individuals in the wild, and zoo management must balance conservation breeding goals with the welfare of these highly territorial solitary predators.
Sumatran tigers in zoos face the fundamental challenge of being adapted for vast solitary territories in inherently space-constrained environments. Pacing stereotypies indicate chronic frustration of ranging and territorial needs. Large, complex enclosures with varied terrain, water features, elevated platforms, and olfactory enrichment (prey scent, novel objects) can partially mitigate these deficits. Social management is challenging — tigers must be separated except for carefully managed breeding introductions. From a conservation perspective, zoo populations serve as genetic insurance; from a welfare perspective, each individual's quality of life matters independently. Best practice facilities invest in both dimensions simultaneously.
