In summer, due to the long sunshine time, the coat will become shorter and darker. In winter, the hair is long, pale and yellowish. In order to blend into the snowy habitat, Siberian tigers have white fur in winter, unlike tigers in warm areas with red stripes. In order to resist the low temperature of MINUS 45 degrees, it has thick fur, which is the most hair per square inch of all tigers.

Siberian tigers often live alone, and only in the breeding season do males and females live together. There are no fixed nests, and most of them wander in the mountains for food. Can swim and climb trees. Due to the development of forest areas and the surge of population, remote areas have developed into villages and towns in the past, and tigers often forage near forest settlements. Tigers are more active at dusk, more dormant during the day and rarely come out without being disturbed. Tigers have a wide range of activities, and their daily foraging activities can reach dozens of kilometers in the north.
How to protect the Siberian tiger?
1. Establish a reserve.
At present, the Northeast Tiger is close to extinction in China, and two places connected with Russian population, Hunchun and its surrounding areas and Dongwandashan, have become the only hope to save the Northeast Tiger. Since the establishment of Hunchun Nature Reserve in 2001(upgraded to national level in 2005), the range and frequency of tiger activities have been on the rise. Although there is no nature reserve in Dongwandashan area, the frequency of tiger activities has obviously increased in recent years due to the decrease of human activities.
2. Absorb the experience of Russian protection.
Russia has created a very successful example. In the past 50 years, the number of tigers in Russia has increased by 10 times. In the late 1930s, there were only 20 to 30 Siberian tigers in Russia. However, due to the active measures taken by the Russian government, the population of Siberian tigers has recovered rapidly. There were 240~250 Siberian tigers in the winter of the mid-1980s, and the number of them reached 4 15~476 in the census of 196. At present, there are 428~502 Siberian tigers, which are basically saturated. The greatest experience of successful tiger protection in Russia is the realization of a wide range of protection.
3. Strengthen law enforcement, put an end to poaching and expand the scope of tiger habitat protection.
The Siberian tiger does not have high requirements for the forest itself. It is not necessarily a virgin forest. A sub-forest with a large number of ungulates can survive as long as there is drinking water and a hidden and safe area. Therefore, in addition to strengthening law enforcement and resolutely putting an end to poaching tigers and their prey, the most important task is to expand the protection scope of tiger habitats.
