A tiger is a solitary animal, which means it is the only tiger in its territory. The territory of a tiger is averagely 2.5 square kilometers. However, the system is a little bit more complicated: the males have a bigger territory that often overlaps with the territory of several females. Moreover, mothers often keep sharing their territory with their daughters (but never with their male descendants, they got chased away by the ruling male).
The distribution of the territories and their size are dependent on the availability of prey. The territories of Siberian tigers for example, that are often covered with snow, is much bigger than the territory of e.g. their brothers in the South of Asia (Bengal tiger and South China tiger).
The vegetation and soil of the territory are very varied: dry forests, rainforests and mangrove. The Siberian tiger lives mainly in the snow. The variation in biotopes also implies that their prey is also varied.
The main part of his live, a tiger lives in the forest, but fields can also belong to his territory.
The tiger occurs in whole South East Asia. Because the subspecies are mainly subdivided by their occurrence (and some different genetic characteristics), you can find their geographical occurrences at the subspecies respective pages.
