Tigers thrive in areas where there are lots of foliage and prey. According to the Seaworld and Busch Gardens Animal Information Database, they can be found in tropical forests, evergreen forests, riverine woodlands, mangrove swamps, grasslands, savannas and rocky country. However, fragmentation and habitat loss have greatly contributed to the decline in the tiger population.
Tigers existed throughout Asia, from Turkey to the Sea of Okotsk in the Far East, and even on the islands of Sumatra, Java and Bali.
Today, tigers no longer live west of India and do not exist on Java or Bali. The tiger population is now fragmented into parts of Southeast Asia, China, and the far eastern part of Russia.

Tigers depend on two things to survive, which ultimately decide their environment. The first is foliage in order for them to stalk and stay hidden. The second is prey--where there is plentiful prey, they can survive.
Habitat loss is a major factor to the decline in tiger populations. Deforestation not only destroys their environment, but also the environment of their prey.
Tigers migrate 50 to 1,000 square km based on their habitat, prey, gender, and the season. This is called their home range.
