Threats to the Siberian tiger are: Poaching, disappearing forests and habitats by deforestation, bad weather conditions that cause their prey not to be able to find food which in turn causes scarcity in the tiger's food supply.
Other carnivores such as the brown bear will steal their food right out from under them.
密猟、森林伐採、悪天候と並ぶ脅威がヒグマ等の肉食獣に獲物を目の前から横取りされる事である。
