Amur tigers are the largest wild cats, with fewer than 600 in the wild, and zoo populations play a critical conservation role — while individual welfare depends on space, solitary housing management, and cognitive enrichment.
Amur tiger welfare in zoos carries a conservation weight that shapes how welfare costs and benefits are evaluated. The small wild population means that zoo genetic diversity genuinely matters for species survival — each individual's reproductive success has conservation significance. However, this conservation rationale cannot justify inadequate individual welfare: tigers that do not thrive reproductively in poor welfare conditions undermine their conservation function as well as their personal wellbeing. Space is the dominant welfare challenge: Amur tigers evolved to range over 1,000 km2, and no zoo can provide remotely comparable movement opportunity. Enrichment that provides hunting simulation — scent trails, puzzle feeders, novel objects, varied feeding schedules — reduces the behavioural deficit from restricted ranging. Year-round outdoor access in appropriate climatic conditions allows thermoregulatory and behavioural expression suited to cold-climate adaptation. Social management must rigorously respect solitary nature while facilitating reproductively necessary contact.
