The Amur leopard is the rarest large cat on Earth, with fewer than 100 individuals in the wild. Intensive conservation efforts are slowly reversing its decline.
Amur leopards at population numbers under 100 face severe inbreeding depression that compromises immune function and reproductive success, creating welfare problems at the population level. Individual leopards in fragmented forests experience stress from insufficient territory and prey. Poaching for skins — each individual loss represents an enormous proportion of the total population — causes acute welfare harm with disproportionate conservation impact. Reintroduction planning requires careful welfare consideration of translocated individuals from zoo populations who must adapt to wild conditions. The species exemplifies how individual welfare and population conservation are inseparable at extreme rarity.
