Siberian Tiger
Overview
The Siberian tiger (Panthera tigris altaica) is the largest subspecies of tiger, inhabiting the northern Korean Peninsula, the Russian Far East, and northeastern China. Its population drastically declined in the early 20th century due to overhunting and habitat destruction, leading to its designation as an endangered species. However, thanks to conservation efforts by Russia and the international community, its numbers are gradually recovering. Currently, it is primarily found in the coniferous and mixed forests of Primorsky Krai and Khabarovsk Krai in Russia.

Morphology and Ecology
The Siberian tiger reaches a body length of 2.7–3.3 m and a weight of 180–306 kg for males and 100–167 kg for females. In winter, it develops thick fur and a layer of fat, enabling survival in extreme cold of -40°C. Its fur is orange with black stripes, and the belly is white. Compared to other tiger subspecies, it has fewer stripes, longer fur, and a mane-like growth around the face. It is nocturnal and solitary, with a home range of 800–1,000 km² for males and 300–500 km² for females.
Diet and Hunting
Its main prey includes large ungulates such as wild boar, deer, and roe deer. Occasionally, it attacks predators like bears or lynxes. It requires an average of 9–10 kg of meat per day, and after a successful hunt, it feeds and rests for several days. When hunting, it approaches stealthily and uses a strategy of biting the nape or throat to suffocate the prey.
Reproduction and Lifespan
The breeding season can occur year-round but is concentrated mainly in December to January. The gestation period is 95–112 days, and a litter typically consists of 2–4 cubs. Cubs are born blind, weighing around 1 kg, are weaned after 6–8 weeks, and stay with their mother for 18–24 months. In the wild, their lifespan is 10–15 years, while in captivity they can live over 20 years.
Habitat and Distribution
Historically, the Siberian tiger ranged across the northern Korean Peninsula, Manchuria, the Russian Far East, and eastern Mongolia. Currently, it is concentrated in the Sikhote-Alin mountain range in Primorsky Krai and Khabarovsk Krai, Russia. A small number also inhabit the Changbai Mountain region in northeastern China. Its habitat primarily consists of mixed coniferous and deciduous forests, preferring mountainous areas at elevations of 500–1,500 m.
Conservation Status
The Siberian tiger is classified as Endangered (EN) on the IUCN Red List and is listed in the Russian Red Book. It is included in CITES Appendix I, which completely bans international trade. As of 2024, the wild population is estimated at about 500–600 individuals, a significant recovery from the 20–30 individuals in the 1940s.
Latest Trends
As of 2024–2025, conservation efforts for the Siberian tiger show the following achievements and challenges. Russia has strengthened habitat protection in areas such as the Sikhote-Alin Nature Reserve and Land of the Leopard National Park, and has introduced monitoring systems using satellite tracking and camera traps. In 2024, the Russian Ministry of Natural Resources and Environment announced that the tiger population had exceeded 600 individuals, approximately double the number in 2010. China is establishing the Northeast China Tiger and Leopard National Park to promote habitat connectivity in border areas with Russia. Meanwhile, habitat reduction due to climate change and poaching (especially for traditional Chinese medicine) remain ongoing threats. In 2025, Russia and China agreed to strengthen joint tiger conservation cooperation, and research on population management through genetic analysis is actively underway.
