01 / In Africa, Southern white rhinos, once thought to be extinct, now thrive in protected sanctuaries and are classified as Near Threatened. But the Northern white rhino subspecies is believed to be extinct in the wild and only a few captive individuals remain in a sanctuary in Kenya. Black rhinos have doubled in number over the past two decades from their low point of 2,480 individuals, but total numbers are still a fraction of the estimated 100,000 that existed in the early part of the 20th century.

02 / A small population of the Javan rhino still clings for survival on the Indonesian island of Java. Successful conservation efforts have helped the third Asian species, the greater one-horned (or Indian) rhino, to increase in number. Their status was changed from Endangered to Vulnerable, but the species is still poached for its horn.
