Amur (Siberian) tiger recovery has been one of conservation's success stories, with population growth dependent on continued prey restoration and habitat protection in the Russian Far East.
Individual Amur tiger welfare depends on adequate prey availability to maintain the body condition needed for successful hunting and reproduction. Tigers in areas with depleted prey populations show reduced body condition, smaller territory sizes, and increased livestock depredation that leads to conflict and retaliatory killing. The welfare recovery of Amur tigers has been inseparable from prey restoration programs - as wild boar and deer populations recover, tigers' nutritional needs can be met without the welfare and conservation costs of conflict with humans.
