Central Africa > Cameroon > Lobéké National Park
Summary[edit]
- Central chimpanzees (Pan troglodytes troglodytes) & western lowland gorillas (Gorilla gorilla gorilla) are present in Lobéké National Park.
- It has been estimated that 2,658 gorillas and chimpanzees occur in the site.
- The great ape population trend is decreasing.
- The site has a total size of 2,153 km².
- Poaching is a key threat to chimpanzees and gorillas.
- The site forms part of the Sangha Trinational transboundary conservation landscape.
Site characteristics[edit]
Lobéké National Park is situated in the southeast corner of Cameroon. The park forms part of the Sangha Trinational (TNS) transboundary conservation landscape, which also includes Dzanga-Ndoki National Park in the Central African Republic, and Nouabalé-Ndoki National Park in the Republic of Congo (N'Goran 2017; BirdLife International 2020). With at least 305 bird species recorded, Lobéké National Park is a designated Important Bird Area (BirdLife International 2020). The saline swamps found in Lobéké attract large numbers of elephants and bongos, and the park contains a significant proportion of untouched primary forest (BirdLife International 2020). The park has one of the highest concentrations of gorillas and elephants in the continent (Sangha Tri-national Trust fund).
