Site characteristics

Altos de Nsork National Park is located in the southeastern corner of Equatorial Guinea. The park was established in 2000 and covers 700 sq. km (UNEP-WCMC 2021). Wildlife here is similar to the wildlife in the nearby forests of Gabon; the park is home to central chimpanzees, western lowland gorillas, forest elephants, black colobus monkeys, mandrills, forest buffaloes, and red river hogs (Scafidi 2015).

Threats

According to a survey of birds and mammals in 1998, the forest at the site was relatively undisturbed, although logging had taken place at the site in the past (Larison et al. 1999). Locals utilized the forest for wood for construction, gathering terrestrial plants and other products, hunting, and agriculture (Larison et al. 1999). Hunting was primarily for subsistence using traps and guns; there was little access to markets. There are no roads in the interior of the park, and only a small part of the park's border is close to roads (Larison et al. 1999). Overall, human presence and disturbance was described as relatively low, but a more recent assessment is needed.
