<P> During the 20th century, tigers became extinct in Western and Central Asia, and in a number of Sunda Islands, and were restricted to isolated pockets in the remaining parts of their range . They were extirpated on the island of Bali in the 1940s, around the Caspian Sea in the 1970s, and on Java in the 1980s . This was the result of habitat loss and the ongoing killing of tigers and tiger prey . Today, their significantly fragmented and depopulated range extends eastward from India to Bangladesh, Bhutan, Nepal, Myanmar, Thailand, Cambodia, Laos, Vietnam, China, Malaysia, Indonesia, North Korea and Russia . The northern limit of their range is close to the Amur River in southeastern Siberia . The only large island they still inhabit is Sumatra . Since the beginning of the 20th century, tigers' historical range has shrunk by 93% . In the decade from 1997 to 2007, the estimated area known to be occupied by tigers has declined by 41% . </P> <P> The tiger occupies a wide range of habitat types, but will usually require sufficient cover, proximity to water, and an abundance of prey . It prefers dense vegetation, for which its camouflage colouring is ideally suited, and where a single predator is not at a disadvantage compared with the multiple cats in a pride . A further habitat requirement is the placement of suitably secluded den locations, which may consist of caves, large hollow trees, or dense vegetation . The Bengal tiger in particular lives in many types of forests, including wet, evergreen, and the semi-evergreen forests of Assam and eastern Bengal, swampy mangrove forests of the Ganges Delta, deciduous forest in the Terai, and thorn forests in the Western Ghats . In various parts of its range it inhabits or had inhabited additionally partially open grassland and savanna as well as taiga forests and rocky habitats . </P> <P> Adult tigers lead largely solitary lives . They establish and maintain territories but have much wider home ranges within which they roam . Resident adults of either sex generally confine their movements to their home ranges, within which they satisfy their needs and those of their growing cubs . Individuals sharing the same area are aware of each other's movements and activities . The size of the home range mainly depends on prey abundance, and, in the case of males, on access to females . A tigress may have a territory of 20 km (7.7 sq mi), while the territories of males are much larger, covering 60 to 100 km (23 to 39 sq mi). The range of a male tends to overlap those of several females, providing him with a large field of prospective mating partners . </P> <P> The tiger is a long - ranging species, and individuals disperse over distances of up to 650 km (400 mi) to reach tiger populations in other areas . </P>
