Specifically, they can monitor the inter-calving interval (the timeframe between births) to determine how the environment impacts black rhino reproduction. Population Status Total population size Approximately 3,140 mature individuals (Emslie 2020a) Most wild black rhinos are conserved in 4 states South Africa, Namibia, Zimbabwe, and Kenya conserve 96 of remaining wild population Populations by subspecies D. They can use this information to determine the breeding success of rhinos in Addo Elephant National Park. Toward this end, zoo researchers developed a field kit that diagnoses pregnancy using black rhino fecal samples. Understanding the factors that naturally control reproduction will help managers-in the wild and zoos-ensure that all black rhinos reach their reproductive potential. However, continued reproductive success is critical for the species’ sustainability, especially given that it is a naturally slow breeder. After a narrow escape from extinction, the black rhino is slowly repopulating its historical range. The black rhino offers a charismatic reminder of prehistoric times, and it has also become an iconic species for conservation efforts. Rhinos have a good reason for being elusive they are poached for their horns, which, in some cultures, are used in traditional medicine. The black rhino is a shy, secretive species that is difficult to observe in the wild. The resulting information helped scientists better manage and conserve this amazing endangered species. Hormone and parasite data was combined with information on behavior, ecology, predation, competition, and tourism. The black rhinoceros, Diceros bicornis, is one of the most endangered species of terrestrial mammals in the world, with an estimated 3,600 animals remaining. Sample collection is made possible by motion-activated field cameras that are used to track rhino movement and habitat usage. To form a clearer portrait of their health, zoo scientists used non-invasive field techniques-the collection of fecal samples-to monitor hormone concentrations and the presence of parasites in this population. With more than 50 individuals, Addo Elephant Nation Park currently boasts South Africa’s largest breeding population of the southwestern arid subspecies of black rhino. With help from conservationists, the rhinos have begun repopulating their historical range-recent surveys show 5,055 individuals-but because they are slow breeders, it’s important to understand the factors that naturally limit reproduction. Prior to the recovery effort, their population dropped from 65,000 to 2,000 individuals. Lincoln Park Zoo scientists assisted the recovery of endangered black rhinos, which were nearly driven extinct during the 1990s by habitat destruction and poaching.
