Panthera tigris altaica The Amur Tiger, the largest of all the tigers, comes from the taiga or snowy forests of the Russian far east. Adapted to live in temperatures of minus 46 degrees celcius, the tiger has 3000 hairs on every square centimetre of its body.
They hunt mainly for deer and boar. Today, this population inhabits mainly the Sikhote Alin mountain region in southwest Primorye Province in the Russian Far East. In 2005, there were 331–393 adult and subadult Siberian tigers in this region, with a breeding adult population of about 250 individuals.
The population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the Russian tiger population was declining. An initial census held in 2015 indicated that the Siberian tiger population had increased to 480–540 individuals in the Russian Far East, including 100 cubs.
This was followed up by a more detailed census which revealed there was a total population of 562 wild Siberian tigers in Russia. As of 2014, about 35 individuals were estimated to range in the international border area between Russia and China.
