Six tiger subspecies remain, each with distinct conservation needs. Zoo management must balance individual welfare with subspecies genetic diversity conservation.
Tiger subspecies conservation in zoos presents a welfare tension between genetic conservation goals and individual animal welfare. Tigers managed for conservation breeding may be paired or transferred based on genetic value rather than individual compatibility - a management decision driven by population genetics rather than the preferences of individual animals. The majority of captive tigers - the hybrids of unknown subspecies - have no conservation value but require the same welfare investment as pure subspecies animals. Their welfare should not be treated as less important because of their genetic status. The conservation rationale for zoo tiger programs is strongest for the most endangered subspecies (Amur, Sumatran) where captive populations provide a meaningful insurance against wild extinction, and weakest for programs that primarily serve display purposes with hybrid animals.
