1 WEEK4 TOPIC :NIGERIAN VEGETATION, FOREST AND FOREST USES NIGERIA VEGETATIONNigeria is a large country with varying vegetation belts. The variations are found from North to South with the belts running from East to West. Climatic factors such as rainfall, temperature, and relative humidity account for these variations, other factors include topography and human activities on land. The type of agricultural activities to be engaged in a particular area depends on the environment.NIGERIAN VEGETATION BELTSThere are two major types of vegetation in Nigeria. These are the ;Forest zonesSavanna zonesFOREST ZONES : The forest vegetation is found in the southern part of the country and comprises of : a. Mangrove forestb. Rain forestMANGROVE FOREST: It is found around swamps of the coastal creeks, estuaries and lagoons of southern Nigeria- Trees found are : red and white mangroves ,palm and lianas (climbing and twining plant)- Animals found are: fish, crocodiles, snakes and birds.
3 B. RAIN FOREST: This area is characterized with rainfall of about 1500mm-2000mm within 8-9 months of rainfall- Found around Ogun ,Oyo , Ondo, Delta, Anambra, Akwa IbomTrees found in this area are oil palm ,iroko, mahogamy, rubber, walnut,obeche.Animals found in this area are, monkeys, antelopes, wart-hogs, snails,grasscutters e.t.c tSAVANNA ZONES: This covers as much as 80% of the country from the northern edge of the rain forest to the southern edge of the Sahara desert. The savanna zone is subdivided into : a. Derived savannab. Guinea savannac. Sudan savannad. Sahel savanna(A) DERIVED SAVANNA : In this zone, farming activities have combined to degrade the original forest vegetation, leaving behind some fire-tolerant savanna species and a few forest trees. Animals found in the derived savanna include antelopes, giant rats, monkey e.t.c(B) GUINEA SAVANNA : This is the largest vegetation belt in Nigeria: It covers the sparsely populated areas of the middle belts. This region is characterized by natural grassland, sparse woodland or trees. This region is dominated by tubers and grain crops. Animals found here include large animals like buffaloes, elephant, lions kept in game reserve, while smaller animals like giant rats , rabbits and wild cats etc. move about freely.
