Endangered and Threatened Wildlife and Plants; Listing the Southern White Rhino (Ceratotherium simum simum) as Threatened

We, the U.S. Fish and Wildlife Service (Service), are adopting as a final rule an interim rule to list the southern white rhino (Ceratotherium simum simum) as threatened under the authority of section 4(e) of the Endangered Species Act of 1973, as amended (Act), due to the similarity in appearance with the endangered Javan (Rhinoceros sondaicus), Sumatran (Dicerorhinos sumatrensis), Indian (Rhinoceros unicornis), black (Diceros bicornis) and northern white rhino (Ceratotherium simum cottoni). The interim rule was necessary, as differentiating between the horns and other products made from the southern white rhino and the endangered Javan, Sumatran, Indian, black, and northern white rhino is difficult for law enforcement to determine without genetic testing, decreasing their ability to enforce and further the provisions and policies of the Act. This similarity of appearance has resulted in the documented trade of listed rhinoceros species, often under the guise of being the unprotected southern white rhinoceros, and this difficulty in distinguishing between the rhino species protected under the Act and the southern white rhino constitutes an additional threat to all endangered rhinoceros species. The determination that the southern white rhino should be treated as threatened due to similarity of appearance will substantially facilitate law enforcement actions to protect and conserve all endangered rhino species. Therefore, for the reasons given in the interim rule and in this document, we are adopting the interim rule as a final rule without substantive change.
