- 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
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).

Research activities
Several studies have been conducted at Lobéké National Park. A recent study found that changes in land cover from 2001 to 2014 influenced great ape nest distribution (Yuh et al. 2019).
