Sumatran tigers are critically endangered with fewer than 400 individuals remaining in the wild, making captive breeding programmes at once urgent and complex from a welfare perspective.
Sumatran tiger welfare requires enclosures that allow expression of natural behaviours including hunting simulation, swimming and scent marking across varied terrain. Chronic stress from inadequate space or monotonous environments leads to stereotyped pacing. Conservation value is maximised when welfare is prioritised, as healthy, behaviourally competent tigers are better breeding candidates.
