INTRODUCTION: All species of tigers extant are endangered. Of the world's eig ht Panthera tigris subspecies, three have been snuffed out: the Caspian, the B ali, and the Javan. Remaining (under parlous circumstances) are the Bengal (In dian), South China, Indochinese, Sumatran, and Siberian (Amur). No one knows how many wild tigers are alive today. The commonly cited estimate of 5,000 to 7,000 is a gue ss; what is certain is that if tigers are to survive in nature, they need massi ve human intervention. ------ LEGEND: The face of a snarling tiger, probably an Indian tiger (Panthera tigris tigris), at this wildlife farm.
