In West Africa, high deforestation rates and poaching have induced dramatic declines of mammal’s populations and local extinctions. Due to their isolation, island species are more vulnerable than mainland species. The premises of that scenario are perceptible in the Ehotilé Islands National Park, south-eastern Côte d’Ivoire, but have not been documented. This study aimed to update the diversity and conservation status of medium and large mammals in that protected area. Several surveys were conducted between 2019 and 2021, using ethno-zoological interviews and individual surveys with local populations, as well as reconnaissance walks and camera trapping to collect data on the presence or absence of mammals. From interviews with local populations and literature review, a list of 27 species of mammals that were potentially present in the park in the past was established. Most “lost” species are large mammals, especially primates that are globally threatened. A total of 11 species were pictorially identified, including two Near threatened species (Aonyx capensis and Hydrictis maculicollis) and one Vulnerable species (Cercopithecus lowei). The study confirms a trend of population decline and the erosion of mammal diversity in the park, hence highlighting the need for urgent conservation actions.
