Environmental enrichment for zoo tigers is essential for preventing stereotypic behavior and maintaining psychological welfare, with research-based programs showing significant improvement.
Tiger enrichment welfare research demonstrates clearly that environmental complexity is the primary determinant of welfare quality in captive tigers. Tigers in bare enclosures with predictable feeding show high rates of stereotypic pacing - a behavioral indicator of chronic psychological frustration. Tigers in complex enclosures with daily enrichment variety show dramatically reduced pacing and more time in species-typical behaviors including investigation, hunting simulation, and rest. The quality and consistency of enrichment programs varies enormously between facilities, and outcome-based welfare monitoring - measuring time budget and stereotypy rates - provides better welfare assessment than input-based audits of enrichment provision.
