Tigers have been revered, feared, and pursued by hunters across their historic ranges. Each subspecies went extinct for similar reasons with slight variations. The Bali tiger & Javan tigers were closely related. Genetic testing shows both subspecies once shared a common ancestor. These two subspecies were smaller than other tigers. This was an adaptation to being on an island where prey was smaller and more limited in quantity. They ate many things but preferred hunting wild boar, rusa deer and banteng. The Bali & Javan tigers also ate smaller animals like ducks and reptiles. After Dutch colonization, the Bali tiger was hunted as a sport. The last confirmed sighting of a Bali tiger was in 1937. The West Bali National Park was created in 1947. There were unconfirmed sightings in 1952, 1970, & 1972. By 1940, the Javan tigers were mostly found in zoos throughout Indonesia. After WWII those zoos were shut down. Then plantations for coffee, rubber, and teak began further fragmenting the remaining wild Javan tigers' habitat. The population plummeted in the mid-1950's due to the rusa deer population decrease. At that time the total population was 20 - 25 individuals. In 1965, civil unrest took more habitat from the tigers. By 1972, only 7 Javan tigers were known to exist. The last confirmed evidence of tiger presence were footprints found in the Mount Betiri Reserve in 1976. There have been unconfirmed sightings of Javan tigers since then. The Caspian tiger had a much larger range that through much of eastern Turkey, the area around the Caspian Sea, Iran, and as far east as the Xinjiang region in China. The first population decline for the Caspian tiger began in the late 1800's when the Russians took over Turkestan. Parties of hunters killed tigers, but when the Russian military began killing the wild boars that the tigers depended on, their numbers declined quickly in that region. During WW I, military groups were hired to clear out large predators and clear forested areas. Its prey was killed by the military and its habitat was further fragmented. Even though Russia, Iran, and Turkey placed bans on Caspian tiger hunting, it was too little too late. The last confirmed sighting of a Caspian tiger was in Turkey near Uludere Hakkari Province in 1970. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Bali tiger, Caspian tiger, and Javan tigers might be good candidates. Scientists would potentially use DNA from the remaining skins and specimens at museums around the world. If these three tiger subspecies were brought to life, could they ever be reintroduced to their native homelands? There have been efforts in all three tigers' former ranges to protect lands through wildlife refuges, national parks, and increased local awareness. Even with these efforts, poaching continues to be a threat to animals living there. With limited habitat and increased human populations could tigers and people coexist once again? There are current efforts to bring Siberian tigers into the former ranges of the Caspian tiger.
