Rain Forest







Mangrove and Fresh Water Swamp Forest

1.

Mangrove and fresh water swamp forest


This occupies the delta part of Nigeria with heavy rainfall of up to 200 cm and more per annum.
The major activities in this region include lumbering (felling of timbers) and fishing.

Swamp rice can also be grown in the area.

2.

Rain forest

This occurs in the Southern part of Nigeria lying above the mangrove and fresh water Swamp Forest. The annual rainfall of this one is about 150 cm to 200 cm.

This region consists of tall woody trees and strong undergrowth. Examples of trees found here include iroko, obeche, opepe, mahogany, afara, etc.

There is a high degree of farming activity in this region. Crops commonly grown are yam, coco yam, cassava, maize, rice, plantain, tocoa, rubber, oil palm, kola, mango, citrus, etc.

Animals include dwarf goat, sheep, pigs, cattle and poultry. Fish ponds are also kept. Guinea savanna This zone is cutting deep into the rain forest due to continued cultivation.

Such areas are now referred to as derived savanna. The Guinea Savanna area is made up of tall strong grasses Interspersed with trees of moderate heights. Aanual rainfall is about 100cm to 150cm.







This zone is the largest vegetation zone in Nigeria. It is an area of intensive agricultural activity. Crops grown include all cereals, legumes such as cow-peas and groundnuts, cotton, yam, cassava and potatoes Livestock include cattle, goat, sheep, poultry and others.

4.

Sudan savanna

This zone is covered with more grasses and short scattered trees and has an annual rainfall of 50 cm to 75 cm. Agricultural activity in this area centres mainly on cattle, sheep and goat rearing. Poultry is also kept while donkeys, camels and horses are equally reared.

Crops grown are mainly sugar cane, millet and sorghum.
Vegetables particularly carrot and tomatoes are grown along river beds, streams and in areas with irrigation facilities.

5.

Sahel savanna

This occupies the extreme north-east of Nigeria with an annual rainfall of about 15 cm to 50 cm.

It is characterized by feathery grasses and highly scattered spiny shrubs (thorn bushes).
Animals are mostly reared here during the rainy season while drought' resistant crops like dwarf sorghum and millet are cultivated.r
