Forest–savanna mosaic

(Redirected from Forest-savanna mosaic)

Forest–savanna mosaic is a transitory ecotone between the tropical moist broadleaf forests of Equatorial Africa and the drier savannas and open woodlands to the north and south of the forest belt. The forest–savanna mosaic consists of drier forests, often gallery forest, interspersed with savannas and open grasslands.

Flora

edit

This band of marginal savannas bordering the dense dry forest extends from the Atlantic coast of Guinea to South Sudan, corresponding to a climatic zone with relatively high rainfall, between 800 and 1400 mm. It is an often unresolvable, complex of secondary forests and mixed savannas, resulting from intense erosion of primary forests by fire and clearing. The vegetation ceases to have an evergreen character, and becomes more and more seasonal. A species of acacia, Faidherbia albida, marks, with its geographical distribution, the Guinean area of the savannas together with the area of the forest-savanna, arboreal and shrub, and a good part of the dense dry forest with prevalently deciduous trees.

Ecoregions

The World Wildlife Fund recognizes several distinct forest-savanna mosaic ecoregions:
