Togo ecological zones.

Ecological Zone 1: Refers to the Northern Plains. It enjoys a Sudanese climate characterized by an average of 6 to 7 months of drought. Rainfall varies from 800 to 1000 mm and water per year. The temperatures are between 17 and 39° C. The predominant vegetation is the Sudan savanna with few islands of dry forests and gallery forests. The soil is tropical ferruginous, sandy.Ecological Zone 2: It is covered with a mosaic of dry forests of mountain and forest galleries. The climate is Sudano-Guinean. The rainy season extends from April to October and the dry season is characterized by the presence of the Harmattan, a dry and cold wind. Rainfall is irregular and reaches 1200-1300 mm of water per year. The soils are thin and contain a high proportion of coarse elements. Ferruginous tropical soils are also present.Ecological Zone 3: It corresponds to the Guinean savannas of central area plains enjoying a tropical climate with a rainy season extends from May to October. Rainfall varies between 1200 and 1500 mm per year. The temperature is between 25 and 40° C. The soils are mainly ferruginous. Semi-deciduous forests are found in the southern part and dry forests in the northern part.Ecological Zone 4: This corresponds to the southern part of the Mount "Togo" and has a sub-equatorial climate of transition, characterized by a long rainy season from March to October with a small interruption in August or September. Rainfall varies between 1300 and 1600 mm per year. The vegetation is constitute of ​​rainforests, on deep red lateritic soils.Ecological Zone 5: It is the South of the coastal plains area, with a sub-equatorial climate, characterized by a lack of rainfall in it's southern part. Rainfall varies from 800 mm at the coast up to 1200 mm per year at the northern limit of the zone. The vegetation is composed by a mosaic of savannah, farmland and dry forests (Kokou and Caballé 2000).
