Biogeographical region in Africa
The Zambezian region is a large biogeographical region in Africa. The Zambezian region includes woodlands, savannas, grasslands, and thickets, extending from east to west in a broad belt across the continent. The Zambezian region lies south of the rainforests of the Guineo-Congolian region. The Zambezian region is bounded by deserts and xeric shrublands on the southwest, the Highveld grasslands of South Africa to the south, and the subtropical Maputaland forests on the southeast.[1]
Vegetation types
The dominant vegetation types in the Zambezian region include:[2]
- Dry deciduous forest and scrub forest
- Zambezian wooded grassland
- Itigi deciduous thicket
- Miombo woodland
- Mopane woodland
- Undifferentiated woodland
- Zambezian flooded grasslands and savannas
- Zambezian halophytics
Biodiversity
Botanist Frank White estimated that the region has 8,500 species of plants, of which 4,590, or 54%, are endemic.[3] The Zambezian region is a centre of diversity for tree species in the genera Brachystegia and Monotes.[4]
