Angolan scarp savanna and woodlands

The Angolan scarp savanna and woodlands is a tropical and subtropical grasslands, savannas and shrublands ecoregion located in the Afrotropic biogeographic realm, covering sub-Saharan Africa and the southern Arabian Peninsula, spanning approximately 136,168 km². Classified under the WWF ecoregion code AT1002, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences warm year-round with seasonal rainfall and a distinct dry period. The dominant vegetation consists of grasses interspersed with scattered trees and shrubs. These conditions create the foundation for the ecological communities found within the Angolan scarp savanna and woodlands.

Ecological Significance

Savannas support some of the most iconic large mammal assemblages on Earth, including herds of grazers and their predators. Fire and herbivory maintain the open grassland structure. The Angolan scarp savanna and woodlands contributes to the broader biodiversity patterns of the Afrotropic realm.

Geographic Distribution

The Angolan scarp savanna and woodlands extends entirely within Angola. This geographic range places it within the Afrotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Angolan scarp savanna and woodlands supports a range of wildlife, including agate cone (Conus ermineus), Alfalfa (Medicago sativa), American Black Nightshade (Solanum americanum), Anil de pasto (Indigofera suffruticosa), Annual Mercury (Mercurialis annua), Arrowleaf sida (Sida rhombifolia), Asian watermeal (Wolffia globosa), Beauty Of The Night (Mirabilis jalapa), and 42 more species.

Conservation

Like many tropical and subtropical grasslands, savannas and shrublands ecosystems, the Angolan scarp savanna and woodlands faces threats from overgrazing, agricultural conversion, fire suppression, and desertification. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
