(the last remaining habitat of the species) found none, but efforts to locate any surviving individuals continued. The illegal poaching, limited anti-poaching efforts, failure of courts to hand down sentences to punish poachers and more all contributed to the species' eventual demise. No animals are known to be held in captivity. On November 10, 2011, the subspecies was declared extinct by the International Union for Conservation of Nature.

Population and decline
The Western Black Rhinoceros was heavily hunted in the beginning of the 20th century, but the population rose in the 1930s after preservation actions were taken. As protection efforts declined over the years so did the number of Western Black rhinos. By 1980 the population was in the hundreds. Poaching continued and by 2000 only an estimated 10 survived.
