Listing white rhinos as endangered could save all rhinos, conservationists say

The measure will put under the act’s protection the last remaining unprotected species of rhinoceros, a move that the organization says could help protect the other four highly endangered species of rhinos – black, Sumatran, Indian, and Javan – from poaching.

The southern white rhino is not as close to extinction as its four cousins, with about 20,000 white rhinos in protected areas and private game reserves in four countries: South Africa, Namibia, Zimbabwe, and Kenya. (The southern white rhino is actually a subspecies of white rhino; its northern counterpart is believed extinct in the wild.)
