A report from the International Union for Conservation of Nature has shown that the population of critically endangered African black rhinos is increasing. According to the IUCN, the total number of African Black rhinos increased from 4,845 in 2012 to 5,630 in 2018. Dr. Grethel Aguilar, acting director general of the IUCN, said that these rhinos are still not safe from extinction. The southwestern black rhino population, a subspecies of the black rhino, has been growing over the last three generations. While poaching is still the main danger to these species, the IUCN said that the countermeasures have improved the conditions.
