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 (CM025), 20 km to the south-west. Most of the intermediate country is now farmed, but there are still patches of forest locally.

Other biodiversity The massif shares, with a few other localities, three Cameroon endemic mammals: Crocidura manengubae, Myosorex okuensis (VU) and Dendromus oreas (VU), although there is no reason to suppose the last two are endangered. The forest on the southern slopes holds two montane frogs that are apparently endemic: Leptodactylodon erythrogaster and Cardioglossa trifasciata, while one or two others are found only here and on nearby Mount Kupe (CM025) and the Bakossi mountains (CM022). Among Cameroon–Nigerian endemic forest butterflies present are Charaxes obudoensis and C. tectonis.
