Atlantic forest
It occupies the first reliefs behind the coastal forest up to almost 800 m altitude but is equally found up to 1000 to 1200 m in the West. The Atlantic forest penetrates 100 to 150 km depth, and toward South, it can reach 200/250km (Nyong- and-Kelle Division). It is characterized by an abun- dance of caesalpiniaceous. More than 2/3 of the caesalpiniaceae of Cameroon’s humid dense forest are found in this specific forest.
Dja forest
The forest region of south-east Cameroon offers an aspect that brings it closer to its neighbouring Congolese one. In this sector exists a hydrogra- phic density whose main elements are constituted by the following rivers: the Dja, Boumba and Ngoko. The Dja forest can be compared to an Atlantic forest without caesalpiniaceae having a few elements of semi-deciduous forest. Among the tree species found in this forest, it is necessary to equally suitable noting the Baillonella toxis- perma (adjap), a gigantic tree 4 to 5 m diameter at it base. Lianas and rattans are equally abun- dant in the forest.
Savannah is a typical vegetation of tropical cli- mate with contrasting seasons: rainy and dry sea-
sons (1400 mm precipitations a year and at least 3-month dry season). Cameroon savannahs can be classified into 3 categories:
Sudan-Guinean wooded
and shrubby savannahs of Adamawa
These are savannahs of altitude between 900 and 1500 m. They are seriously damaged because of clearing, grazing and bush fires. Their constituting trees are Daniellia Oliveri, Lophira Lancedata or false shea.
Wooded savannahs
and dry medio-sudanian woodlands
The two types are distant from one another: the one in the south goes through the North-West Region (frontier zone with Nigeria).
The other one in the north is situated down side Benue basin. The grassy vegetations in this area are essentially made up of graminae (cymbopo- gon giganteres, Diheteropogon hagerupiti, Elgemandra androphila).
Sudano-sahelian wooded savannahs of Benue basin
These savannahs extend farther north in latitude over large areas in the Benue basin and advance up to the 10th parallel to the south of the Diamare and Mayo-Danae Divisions. The most common plant species are Boswellia dal- zielli, Asphora padonculata and Hexalobus Monopetalus.
