I found this excerpt in one of our grant proposals and thought it provided some good background on the local ecosystem.
Oban Hills, Cross-Sanaga bioregion
Hot moist tropical climate. A distinct wet season (April to November) and dry season (December to March) season, with average annual temperature of approximately 30 degrees and 80-90% humidity; humid forest (lowland rainforest).Very high rainfall of approximately 3000 mm per annum
The area is mountainous (the Oban Hills) characterized by deeply dissected terrain consisting of steep river valleys, low lying hills, flood plains, maximum altitude approximately 500m. There are two extinct volcanoes in the area that reach a height of 800 and 900 m above sea level.
The vegetation of the Oban Hills is mostly undisturbed primary lowland rainforest, with some areas of farmland, secondary forest, farm bush and selectively logged forest. Apart from the nearest city of Calabar with a population of 500,000, the area is characterised by small relatively remote scattered forest communities population between 300 and 5000. For these villages, farming is the primary source of income, but hunting, some small scale logging and the collection of non timber forest products is also economically important. Ethnically, all peoples in the area come from ethnic minorities. Tribal allegiances are strong and the traditional chieftaincy system is an important institution in most villages.
