Bali Tiger The Bali tiger, native to a small island in Indonesia named Bali, is the smallest of the three subspecies of tigers found in Indonesia. The deforestation caused due to human encroachment was the major factor which affected the basic existence of the Bali tiger. This was followed by extensive hunting of this species, especially during the World War II, which had a serious impact on the tiger population and by the end of the World War II the animal was virtually extinct. The last documented sighting of a Bali tiger was in form of an adult female that was killed in West Bali in September 1937.
