Relief and Climate of Eyumojock

The Northern part of the Eyumojock area is undulating with knife-edge ridges which forms the watershed around the Akwaya region, with an elevation between 135 m to 237 m above sea level. As one moves towards the Center and South, the area becomes more broken and hilly, with an elevation which ranges from 200 m to 800 m above sea level. The topography towards the East forms a river bed escarpment with Munaya River which continues with gentle slope with granitic out-crop.

   Eyumojock consist of two main seasons which is the rainy season and the dry season season. The long rainy season of about seven months starts from April to October with record of the highest monthly rainfall indicated in July. The short dry season of about five months begins from November to March.

In 2005 and 2007, mean monthly temperature ranged from 25c to 29.3c with a maximum monthly record of 27.9c in March and a minimum record of 20.4c in August. Highest temperatures are experienced in the dry seasons due to constant sun light.


The drainage system of Eyumojock is characterised by many small streams which take their rise from the Forest Management Unit. The streams in this area eventually empty themselves into Rivers Awa, Munaya, Badi, Ma’a and Manyu. The main rivers in the Central Ejagham include Rivers Badi, Munaya, Manyu and Bakogo with streams like Bawan, Bakip, Akolayip and Moniem.

Dumort description of soils in the south west Region in 1965 showed that Precambian gneiss and cretaceous sedimentary sandstones which form old basement complex decomposes in situ in to old sandy soils. The soils in the South of the area is highly leached due to heavy rainfall, while the soils in the North East are very fertile due to the alluvial deposit, making the sedimentary soils to be good for the cultivation of oranges, cassava and palms. Due to excessive heat during the dry season, soils loose almost all moisture making farming less productive except during the wet season.


Eyumojock vegetation is classified as lowland of the Guinea Congolian type (White, 1993). It is a moist lowland evergreen forest rich in families of moracae and Cesalpinaceae. Lejoly (1996) described the forest more as an ‘Atlantic lower-Guinea domain to emphasis the influence of the Atlantic ocean. The southern and northern part of Eyumojock are characterised by a mixture of primary and secondary rainforest which decreases in intensity as one moves towards the east or west. They have a higher diversity of flora and richer in species than any other part. Plant species include, Iroko, Bubinga, Poga, Doussie and Moabi.
