The 12 states of Nigeria comprise 356,700 sq mi. The six northern states (North-Western, North-Central, North-Eastern, Kano, Benue-Plateati, and Kwara) cover 79% of total area, but, with the exception of Kano State, have relatively low population densities. The three eastern states (East-Central, South-Eastern and Rivers) account for 8% of total area, and in some locations have more than 1,000 persons per sq mi. The Western State, with 8% of total area, averaged 326 persons per sq mi in 1963, and Mid-Western State 170 persons.

The land rises gradually from the low-lying coastal areas of the south as mangrove and freshwater swamps give way to tropical high forests and successive belts of savanna land. The Niger river, flowing from north- west in Dahomey, and the Benue, flowing from Cameroon on the east through this savanna, converge at Lokoja, and flow about 250 mi southward into the great Niger Delta and the Atlantic Ocean. North of these river valleys, the park-like savanna predominates into Sudan savanna over the northern border and into the Sahara desert. In the north-central part of the country, a great plateau rises as a steep escarpment from the riverain plains of the Niger-Benue to an average height of 2,000 ft above sea level, with ranges of hills 5,000-6,000 ft around Jos. There also are highlands in the east along the Cameroon border. The amount of highlands, however, is limited. More than 90% of total area is less than 2,000 ft above sea level; almost one-half is less than 800 ft. Climate 3. Nigeria's climate is tropical -- humid tropical in the south and dry tropical in the north. Temperatures along the southern coastal area vary from 70° to 90°F, but in the north range more widely, reaching over 1000 F and sometimes dropping below 500F. Annual rainfall ranges from more than 160 in in the south-east to 20 in and lower in the north-east. There are two weather seasons: the rainy season, which usually lasts from April to November in the south and from May to October in the north, and the dry season during the rest of the year. The north has periods of up to seven months with less than one inch of rain (see Map of Ecological Zones, Volume I). During the dry months, north-east trade winds blow from the Sahara, bringing a dry, dustladen wind known as the harmattan. For a few days each year, the wind is felt as far south as the coast. In the wet months, a south-west monsoon blows from the Gulf of Guinea, bringing, rain. Vegetation 4. Vegetation can be broadly divided into east-west parallel bands, ranging from mangrove and fresh-water swamp forest along the coast to closed high forest in the south and open thorn savanna in the north. There is some grassland on the Jos Plateau in the center of the country and some mountain forest and grassland on the Mambilla Plateaiu in the south-east along the Cameroon border. About 80% of the country is covered by savanna of different types. Table 2 below lists the vegetation zones and approximate areas of each, moving from mainly north to south, and see Map of Ecological Zones.
