Site details


Site description: Mont Manengouba is situated to the north-west of the town of Nkongsamba. The crater of the volcanic mountain, at 1,950 m, is a large grassy plain c.3 km in diameter with a few low hills, a marshy area to the south and two small, deep volcanic lakes. The surrounding escarpments are very steep, except on the north-western side. The peak (2,411 m), on the south-eastern rim, is forested, while the southern rim is less high (2,100 m) and gives access to extensive forested slopes to the south. Most of the forest in the caldera grows up the eastern and southern rims with a little on the edge of the lakes. It is rather scrubby, with Maesa lanceolata the dominant species and some tall Polyscias fulva locally. However, the largest expanse of forest, which is also much denser, is to be found on the wetter southern and south-eastern slopes, down to an altitude of 1,500 m (above the village of Nsong), but extending lower in the south-east (1,100 m), mainly as galleries. There is little doubt that, in the past, there was a forest continuum between the lower (southern) slopes of Manengouba and Mount Kupe, 20 km to the south-west. Most of the intermediate country is now farmed, but there are still patches of forest locally. The scrubby forest in the crater is little used by the few Fulani cattle-herders in the area and is only marginally damaged by fires.
Rationale for qualifying as KBA: This site contains the entire known populations of Arthroleptis perreti, Cardioglossa manengouba, Cardioglossa trifasciata, Leptodactylodon erythrogaster, and Phrynobatrachus manengoubensis. The White-throated Mountain-babbler and Green-breasted Bush-shrike meet B2 while an additional 112 birds and two mammals meet legacy KBA criteria and are in need of reassessment.
Manageability of the site: This site was identified as a KBA in 2001 and as an AZE during the 2015-2018 AZE project. The Mont Muanenguba Strict Nature Reserve (WDPAID: 555720257) was recently proposed and covers approximately half of the KBA boundary.
Delineation rationale: This site was identified as an IBA/KBA in 2001. An original delineation rationale is not available.
