Site characteristics

Minkébé National Park is situated in northeast Gabon, bordering Cameroon to the north and Republic of Congo to the east. The forest in Minkébé is extremely rich in bird biodiversity, and has been designated an Important Bird Area (BirdLife International 2020). Minkébé is the name of an ancient village and colonial post that was built on a ridge and abandoned in the 1930s (BirdLife International 2020). The site forms part of the Tri-National Dja-Odzala-Minkébé (TRIDOM) transboundary conservation landscape, spread across Gabon, Cameroon, and the Republic of Congo (WWF).

Threats

Poaching is a major threat, not just to great apes- between 2004 and 2014, more than 25,000 forest elephants were killed for their ivory in Minkébé, representing a 78-81% population decline (Poulsen et al. 2017). Gold mining has also been a major threat. In 2011, the Gabonese National Parks Agency (Agence Nationale des Parcs Nationaux / ANPN) and the Gabonese military expelled over 6,000 gold miners; illegal mining camps had grown exponentially as a result of soaring gold prices over the previous 2-3 years. Severe elephant poaching and other illegal activities were linked to these camps (ANPN 2013).

Category Specific threats Threat level Description Year of threat
10 Geological events Absent
12 Other threat Absent
3 Energy production & mining 3.2 Mining & quarrying High (more than 70% of population affected) Gold extraction and presence of several illegal gold camps, in the park and in its buffer zone (BirdLife International 2020; ANPN 2013). Ongoing (2020)
5 Biological resource use 5.1 Hunting & collecting terrestrial animals High (more than 70% of population affected) Commercial hunting for local bushmeat trade (BirdLife International 2020). Hunting camps and huntings signs (gun shots, trails, elephant carcasses) present at the park during a 2012 survey (ANPN 2013). Ongoing (2020)
8 Invasive & other problematic species, genes & diseases 8.4 Pathogens High (more than 70% of population affected) Extremely low densities of gorillas and chimpanzees were found between 1998-2000, compared to data collected before 1994. The decline resulted from Ebola outbreaks in 1994 and 1996 in the area (Huijbregts et al. 2003; Walsh et al. 2003). 1994, 1996
5 Biological resource use 5.3 Logging & wood harvesting Present (unknown severity) Logging (BirdLife International 2020). Ongoing (2020)
1 Residential & commercial development Unknown
2 Agriculture & aquaculture Unknown
4 Transportation & service corridors Unknown
6 Human intrusions & disturbance Unknown
7 Natural system modifications Unknown
9 Pollution Unknown
11 Climate change & severe weather Unknown
