The habitat of Siberian tigers ranges from the birch forests of eastern Russia to China and North Korea, although the majority of the population is located in Russia. It is estimated that there are 400 to 500 Siberian tigers living in the wild as of 2014.
Of all the tigers, the Siberian's habitat is the furthest north, and it's much harsher than the environment of its counterparts. The harshness of the climate and remoteness of the habitat mean that less people are present and the ecosystem is more intact, a luxury other tiger subspecies do not have. The Siberian tiger is the largest of all the tiger subspecies, weighing in at 660 pounds, and about 10 feet long. Like all tigers, the biggest threat to the Siberian tiger is habitat destruction and hunting. As of 2014, all five tiger subspecies are listed as endangered, and many conservation measures are in place to protect them. Most tigers avoid humans, and some have been known to become man eaters, but this usually occurs when the tiger is too sick or injured to hunt its normal prey. Female tigers give birth to two to six cubs that they raise for two to three years.
