Odzala-Kokoua has approximately 100 mammal species,and one of the continent's most diverse primate populations.Odzala-Kokoua was once home to nearly 20,000 gorillas.In 2005, Ebola killed approximately 5,000 gorillas within a 1,042 sq mi (2,700 km2) area of the park, according to the United States Fish and Wildlife Service.The number of gorillas in Odzala-Kokoua has since increased, following efforts by conservation organizations and at least one tourism company to preserve and rehabilitate the park.
A survey of diurnal primates, conducted during the mid 1990s, showed significant monkey populations in Republic of the Congo's forest region.Odzala-Kokoua had the highest densities of western lowland gorilla and chimpanzee in Central Africa recorded to date.High forest productivity and decreased poaching is thought to have contributed to this success.
The results of a survey conducted in clearings within the northern part of the park, published in 1998, showed the presence of thirteen large mammals, the most frequent of which were the bongo, buffalo, African elephant, forest hog, giant forest hog, gorilla, and sitatunga.Other mammal species recorded include the African civet,African forest elephant, black-and-white colobus, and common chimpanzee.Poaching has been attributed to the park's elephant population decline.There were approximately 9,600 elephants, as of 2014.
Spotted hyenas were reportedly abundant in the park's savanna area in 2007.In 2013, the lion was considered locally extinct, as the species has not been recorded for fifteen years.But at least 46 hyenas were recorded in the park's savanna ecosystem. Also, African golden cat, leopard, and serval were recorded. The decline of lion and spotted hyena populations are thought to b caused by overexploitation.Antelope species include the bay duiker, black-fronted duiker, Peters' duiker, and white-bellied duiker.
Several authors noted the importance of forest clearings for the park's mammal populations.
Approximately 440 bird species have been recorded in the park. #congobrazzaville #discovercongo #visiterlafrique #congo #242
