Site characteristics

Nki National Park is located in the south-eastern Cameroon, bordering the Republic of Congo to the south and Boumba-Bek National Park to the north. The national park was established in 2005 (UNEP-WCMC 2021). Nki National Park is part of the TRIDOM conservation landscape, which is spread over three countries: Gabon, Cameroon, and Congo (WWF n.d.). The TRIDOM landscape is very rich in biodiversity, and 97% of its surface is covered by forest (WWF n.d.), representing approximately 10% of the Congo Basin rainforest (WWF n.d.). TRIDOM is also home to an indigenous Baka population of around 10,000 people (WWF n.d.). In addition to gorillas and chimpanzees, the site harbors a wide variety of mammals, including elephants, buffaloes, giant forest hogs, sitatungas, and several species of duikers (WWF n.d.).

Threats

Poaching, facilitated by the traffic of automatic weapons, has been a major threat at the site (WWF n.d., N'Goran 2017). Other human activities, such as illegal mining and logging are also a threat to wildlife and their habitat at Nki National Park (N'Goran 2017).

IUCN Threats list

Conservation activities

The site is part of WWF's Jengi programme, which supports the management of Nki National Park and other sites that are part of the TRIDOM and TNS conservation landscapes. Anti-poaching measures seem to be showing positive results, as camera traps have recently captured a large herd of elephants (WWF 2017, WWF 2020).

Table 4. Conservation activities reported for Nki National Park

Category Specific activity Description Implementing organization(s) Year of activity
2 Counter-wildlife crime 2.3 Conduct regular anti-poaching patrols Government eco-guards are permanently stationed in the park and anti-poaching patrols are regularly conducted (WWF 2017). Ongoing (2017)
2 Counter-wildlife crime 2.11 Implement monitoring surveillance strategies (e.g., SMART) or use monitoring data to improve effectiveness of patrols Wildlife monitoring team spends at least 15 days inside the park; camera traps help monitor wildlife (WWF 2017). Ongoing (2017)
5 Protection & restoration 5.2 Legally protect ape habitat The site was declared a National Park in 2005 Ongoing (2021)
