So much of Borneo is still uninhabited by man—it must be the leaśt densely populated part of tropical Asia—that it is difficult to imagine its wild fauna being endangered. Much the larger part of the island is still jungle, visited only (if at all) by nomadic groups. But a few species, conspicuous and attractive to humanity for size, food, medicine or beauty, are to-day in danger in all the four territories (Indonesian Borneo, and the British western section comprising North Borneo, Sarawak and Brunei).
