Sumatran tigers are critically endangered with fewer than 400 remaining in the wild. Zoo populations play a vital conservation role, but excellent individual welfare is essential to justify captive management.
Sumatran tiger welfare in captivity is deeply connected to their conservation value: a tiger who thrives and reproduces in a well-managed program contributes to genetic diversity that may one day support wild population restoration. Individual welfare requires meeting the needs of a large, solitary predator with wide-ranging instincts — complex hunting enrichment, large naturalistic spaces, and respect for their solitary nature. Stereotypic pacing in tigers is one of the most recognized public indicators of inadequate captive welfare. Modern facilities that provide rich, dynamic environments significantly reduce stereotypic behavior and enable tigers to express species-typical repertoires.
