By the 1980s, the Amur tiger population had increased to around 500. Although poaching increased after the collapse of the Soviet Union, continued conservation and antipoaching efforts by many partners have helped keep the population stable at around 540 individuals.
The Amur tiger’s habitat is now restricted to the Sikhote-Alin range in the Primorski and Khabarovsk provinces of the Russian Far East, small pockets in the border areas of China and possibly in North Korea. The high latitude means long winters and that the sun does not rise far above the horizon.
Amur tigers have the largest home range of any tiger subspecies because they have to search over large areas to find food due to low prey densities. They represent the largest unfragmented tiger population in the world.
