(a) Sketch map of Nigeria showing vegetation areas

The vegetation changes mainly from wetter conditions in the south to drier conditions in the north. Therefore, mangrove swamp occurs around the Niger Delta coast; rain forest occurs inland in southern Nigeria; Guinea savanna occurs in the Middle Belt; and Sudan savanna occurs in the far north.

(b) Three trees found in the forest zone of Nigeria

• Mahogany
• Iroko
• Obeche

Other acceptable examples include African walnut, opepe, sapele and silk cotton.

(c) Four contributions of forest vegetation to Nigeria’s economic development

1. Supply of industrial raw materials: forests provide timber for sawmills, furniture and plywood industries, as well as materials such as latex for rubber production.
2. Employment: forestry provides work for lumbermen, hunters, sawmill workers, carpenters, transporters and people involved in forest-product trade.
3. Construction and export earnings: wood is used for building houses and making furniture. Timber can also be exported, earning foreign exchange for Nigeria.
4. Food, medicine and tourism: forests provide fruits, nuts, herbs and medicinal plants. They also support wildlife and attractive natural areas, which can promote tourism.

Examination reminder: For economic contributions, state both the forest product or service and how it helps the economy, such as providing jobs, supplying an industry, supporting construction or earning foreign exchange.
