There used to be as many as 8 different subspecies of tigers in the world. Hunting and habitat loss have driven three subspecies to extinction. The Bali, Javan and the Caspian tigers are gone from the earth. The Bengal, Indo -chinese, South chinese, Sumatran and Siberian tigers remain, but their numbers are declining .
Siberian Tigers live in Russia. The main threat to the Siberian tiger in Russia is logging which causes loss of habitat for the tigers and illegal hunting known as poaching. All tigers are listed as endangered. Once tigers numbered 50,000 to 80,000 world wide. Now primarily because of hunting and loss of habitat the numbers are estimated as low as 5,000 to 7,000.
