Zambezian coastal flooded savanna

AT0906 Afrotropic Flooded Grasslands & Savannas 19369 km²

The Zambezian coastal flooded savanna is a flooded grasslands and savannas ecoregion located in the Afrotropic biogeographic realm, covering sub-Saharan Africa and the southern Arabian Peninsula, spanning approximately 19,369 km². Classified under the WWF ecoregion code AT0906, 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 coastal flooded savanna.

Ecological Significance

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

Geographic Distribution

The Zambezian coastal flooded savanna extends entirely within Mozambique. This geographic range places it within the Afrotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Zambezian coastal flooded savanna supports a range of wildlife, including Abalone (Haliotis queketti), Abalone (Haliotis unilateralis), African Blackwood (Dalbergia melanoxylon), African wild dog (Lycaon pictus), Aroma (Dichrostachys cinerea), Australian redcedar (Toona ciliata), Awnless Barnyard Grass (Echinochloa colonum), Beauty Of The Night (Mirabilis jalapa), and 42 more species. Among these, 2 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 coastal flooded savanna 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.
