Zambezian flooded grasslands

AT0907 Afrotropic Flooded Grasslands & Savannas 201936 km²

The Zambezian flooded grasslands is a flooded grasslands and savannas ecoregion located in the Afrotropic biogeographic realm, covering sub-Saharan Africa and the southern Arabian Peninsula, spanning approximately 201,936 km². Classified under the WWF ecoregion code AT0907, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences seasonal flooding with waterlogged soils for significant portions of the year. The dominant vegetation consists of grasses and sedges adapted to periodic inundation. These conditions create the foundation for the ecological communities found within the Zambezian flooded grasslands.

Ecological Significance

These wetland ecosystems are critical for waterbirds, fish, and amphibians, serving as nursery habitats and seasonal migration stopover points. The Zambezian flooded grasslands contributes to the broader biodiversity patterns of the Afrotropic realm.

Geographic Distribution

The Zambezian flooded grasslands extends across Angola, Botswana, Congo (DRC), Malawi, Mozambique, Namibia, and 2 other countries. This geographic range places it within the Afrotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Zambezian flooded grasslands supports a range of wildlife, including Abalone (Haliotis queketti), Abalone (Haliotis unilateralis), African Blackwood (Dalbergia melanoxylon), African dogstooth grass (Cynodon transvaalensis), African senna (Senna didymobotrya), African wild dog (Lycaon pictus), agate cone (Conus ermineus), Alfalfa (Medicago sativa), and 42 more species. Among these, 6 species are classified as threatened on the IUCN Red List, underscoring the conservation importance of this ecoregion.

Conservation

Like many flooded grasslands and savannas ecosystems, the Zambezian flooded grasslands faces threats from dam construction, drainage for agriculture, water diversion, and pollution. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
