Site description The site, in the far north of the country, comprises the Nouabalé–Ndoki National Park sensu stricto (386,600 ha) plus some of the peripheral zone from its western border, the Ndoki river, to Bomassa and the immediate surroundings, including sandbars on the Sangha river, south to the village of Bounda and north to the international border with the Central African Republic, where it is contiguous with Dzanga–Ndoki National Park (CF008). The park contains 3,866 km² of undisturbed forest within the basin of the Nouabalé and Ndoki rivers, mainly between 340–400 m. The forest is of three types: swamp-forest along the main rivers, closed-canopy monodominant Gilbertiodendron dewevrei forest (often in narrow strips bordering the swamp-forest) and dryland forest, by far the most extensive. The latter is semi-evergreen with an open, mixed canopy (Sterculiaceae and Ulmaceae are important) and the understorey is usually very dense and dominated by Marantaceae and Zingiberaceae. This Sterculiaceae/Ulmaceae forest-type is characteristic of the northern fringes of the Guineo–Congolian forest block. There is also some secondary forest around Bomassa camp (the park headquarters) and village; human impact in the buffer zone is minimal today. Most of the peripheral zone to the west and south of the park has been logged once, at an intensity of about one tree per hectare. Finally, there are some small natural clearings in the forest in marshy depressions dominated by various types of herbaceous vegetation, including Cyperaceae swamps, locally called ‘bai’.
