      Biosphere Reserve Information
     

Nigeria

OMO

 
       
  General Description   This biosphere reserve is situated about 135 km north-east of Lagos in the south of Nigeria. Major habitats are dry evergreen mixed deciduous forests in the north and wet evergreen forests in the south. However, plantations and agricultural land can also be found. Main plant species of the area are for instance Diospyros spp., Dracaena manni, Khaya ivorensis and Cordia millenii. Animal species include the grasscutter (Thryonomys swinderianus), the pangolin (Manis tetradactyla), the tree hydrax (Dendrohyrax arborea) and the elephant (Loxodonta cyclotis).
About 6,000 people live within the biosphere reserve boundaries (1998). Their major economic activities are taking place in the transition area: timber exploitation, fuelwood harvesting, cultivation of arable crops, establishing plantations of indigenous and exotic tree species, hunting and fishing. Loss of biodiversity and soil erosion are the main threats to the biosphere reserve. There are several research programmes in place such as climatic measurements and soil changes with different land use practices, bio-productivity studies, and indigenous knowledge and practise in hunting and fishing as well as the utilisation of non-timber forest products.
