Site description Omo Forest Reserve is located about 135 km north-east of Lagos, some 20 km from the coast. The terrain is undulating and elevation reaches about 300 m on some rocky hills. The eastern border is formed by the Omo river which, with its many tributaries, drain the reserve. Omo is contiguous with five other, highly degraded, Forest Reserves, the largest of which is Oluwa Forest Reserve to the east. The vegetation is mixed moist semi-evergreen rainforest. Due to selective exploitation in the past, the forest is largely mature secondary, with pockets of primary forest along river courses and in other areas where log extraction is difficult. Average annual rainfall is over 2,000 mm.
