Tigers can live in a variety of habitats. Mostly they need to hide, to be near a water source, and have enough prey to eat. Tigers are solitary and they all control large amounts of territory, the size of which depends on the availability of food and prey. According to Tigers-World, a male tiger may live and hunt in an area of 60 to 100 square kilometers (23 to 39 square miles). A female tiger may have 20 square kilometers (8 square miles). According to the United States Fish and Wildlife Service, a single tiger can live in a territory as small as 21 square kilometers (8 square miles) to as large as 995 square kilometers (385 square miles). Bengal tigers in particular live in many types of forests. These include the wet, evergreen of Assam and eastern Bengal; the swampy mangrove forest of the Ganges Delta; the deciduous forest of Nepal, and the thorn forests of the Western Ghats.
