Question 1 Report
(a) Draw an outline map of Nigeria. On the map, show and name:
(i) the forest belts
(ii) an important town in each belt
(iii) the Lake Chad
(b) Describe three characteristics of any one of the forest belts shown on the map.
(c) Outline three ways in which the forest belts are of importance to Nigeria.
Answer Details
(a) Outline map of Nigeria showing the forest belts, towns and Lake Chad
Key: Mangrove (salt-water swamp) forest: Port Harcourt; Freshwater swamp forest: Warri; Tropical rainforest (high forest): Benin City. Lake Chad is shown at the north-eastern boundary of Nigeria.
(b) Characteristics of the tropical rainforest (high forest)
- It consists of very tall evergreen broad-leaved trees, commonly reaching about 60 m in height.
- There is a great variety of tree species rather than pure stands. Important species include iroko, mahogany, obeche and walnut.
- The vegetation has distinct layers, namely upper, middle and lower storeys. The closed canopy admits little sunlight to the forest floor, so undergrowth is sparse. Buttress roots, lianas, climbers and epiphytes are common.
(c) Importance of the forest belts to Nigeria
- They provide timber and poles for building, furniture making, paper production and other industries.
- They supply firewood and charcoal for domestic fuel, as well as useful products such as fruits, nuts, rubber and medicinal herbs.
- They conserve wildlife and provide sites for tourism; timber exports also earn foreign exchange for Nigeria.
