Site characteristics
UFA 10-011_ZICGC1, is part of the TNS (Tri-National de la Sangha) landscape, a UNESCO World Heritage site known for its exceptional biodiversity. It hosts a range of endangered and endemic species, including the western lowland gorilla and chimpanzee, both of which are critical species in conservation efforts. The area’s ecological importance lies in its dense tropical forests, which act as a significant carbon sink and support high levels of biodiversity. The site is rich in cultural value, with local communities relying on the forest for sustainable resources, though conservation efforts aim to reduce pressure from hunting and land encroachment. Special designations include its role as part of a larger transboundary conservation initiative, promoting cross-border cooperation between Cameroon, Congo, and the Central African Republic.

Research activities
The primary focus of research at the site includes ecological monitoring, biodiversity assessments, and the monitoring of key species including gorillas and chimpanzees. These activities are part of larger efforts to track population dynamics, habitat health, and threats to wildlife, such as poaching and habitat destruction.
The research is primarily driven by WWF, with support from various academic and conservation partners. Field surveys, including distance sampling and habitat surveys, are regularly conducted to gather data on species density and distribution. Additionally, long-term monitoring is implemented to track the effectiveness of conservation strategies and to adapt management practices accordingly. WWF's Jengi-TNS program is heavily involved in these efforts, with collaboration from local institutions and international research teams.
The research activities are crucial for informing adaptive management strategies and ensuring the effectiveness of conservation interventions. The scientific references in the document, such as Beuko et al. (2019), highlight the ongoing efforts to monitor and assess biodiversity within the area and provide evidence for the development of more effective conservation policies.
