The Siberian tiger, also known as the Amur tiger, is the largest tiger subspecies and is native to the Russian Far East and northeastern China.

The Siberian tiger distribution by country:

1. Russia: The primary range of the Siberian tiger is in the Russian Far East, particularly in the Amur region and surrounding areas. This includes territories such as the Sikhote-Alin Biosphere Reserve, Lazovsky Nature Reserve, and Land of the Leopard National Park. The largest population of Siberian tigers is found in Russia.
2. China: Historically, the Siberian tiger also roamed across parts of northeastern China, including provinces like Heilongjiang, Jilin, and Hebei. However, due to habitat loss and poaching, their range in China has greatly diminished. Efforts are underway to reintroduce them to suitable habitats in China, particularly in the Changbai Mountains along the China-Russia border.

Siberian tigers inhabit temperate forests, coniferous woodlands, and mountainous regions, where they prey on deer, wild boar, and other large ungulates. They are critically endangered, with only a few hundred individuals estimated to remain in the wild. Conservation efforts focus on protecting their remaining habitat, combating poaching, and mitigating human-wildlife conflicts to ensure the survival of this majestic big cat.
