Central Zambezian miombo woodlands is a large Afrotropical ecoregion characterized by seasonally dry woodlands dominated by miombo tree species, forming a broad belt across south-central Africa that influences biodiversity, hydrology, and regional livelihoods. The ecoregion links major rivers and plateaus and underpins conservation efforts by organizations and governments across Angola, Zambia, Democratic Republic of the Congo, Malawi, and Tanzania.

Geography and extent

The ecoregion spans plateaus, river basins, and escarpments including parts of the Kasai River, Zambezi River, and Luangwa River catchments, and approaches the Congo Basin, Lake Malawi, and the East African Rift. Major protected areas and landscapes intersecting the ecoregion include Kafue National Park, South Luangwa National Park, Luambe National Park, North Luangwa National Park, and Nyika National Park, as well as conservation landscapes overseen by entities such as the Peace Parks Foundation and national wildlife services of the involved states. Topography ranges from lowland plains to rolling hills associated with the Katanga Plateau and Central African Plateau, with seasonal floodplains and dambos influencing connectivity to adjacent ecoregions like the Angolan miombo woodlands and the Zambezian and mopane woodlands.

Climate and soil

The climate is strongly seasonal with a wet summer and a long dry season, governed by the movement of the Intertropical Convergence Zone and the regional influence of the Indian Ocean monsoon and inland continental air masses. Mean annual rainfall varies from about 700 mm to over 1,200 mm, producing marked contrasts between gallery forests and dry woodland; mean temperatures are moderated by elevation on plateaus such as the Nyika Plateau. Soils are generally nutrient-poor, well-drained oxisoils and sandy loams derived from weathered precambrian basement and sedimentary rocks of the Katanga Supergroup, while seasonally waterlogged dambos form organic-rich peat and silty soils that support distinct vegetation assemblages and influence carbon storage dynamics relevant to United Nations Framework Convention on Climate Change reporting and national Nationally Determined Contributions.

Flora

Miombo-dominant tree genera such as Brachystegia, Julbernardia, and Isoberlinia form open-canopy woodlands with an understorey of grasses, lianas, and shrubs adapted to fire and drought; mixtures may include patches of Combretaceae species and riparian gallery forest dominated by Ficus, Syzygium, and Erythrina along rivers and dambos. Phenology is marked by deciduous leaf drop during the dry season, and many species host nitrogen-fixing Fabaceae associations that shape nutrient cycling; notable trees include Brachystegia spiciformis and Julbernardia globiflora, which are central to traditional uses such as timber, charcoal, and bee forage for apiculture practiced by communities linked to institutions like the Food and Agriculture Organization programs. Fire regimes driven by lightning and anthropogenic burning influence species composition and fuel loads, interacting with invasive plant management priorities raised in regional strategies by entities including the African Union.

Fauna

The woodlands support diverse megafauna and mesoherbivores including populations of African elephant, Loxodonta africana found in corridors between Kafue and Luangwa systems, as well as large savanna species such as Loxodonta relatives, Plains zebra, Common eland, Loxodonta africana-associated seed dispersers, and grazing ungulates like African buffalo and Impala. Carnivores include African lion, Panthera leo, African wild dog, Lycaon pictus, and Spotted hyena, while smaller mammals such as bushbuck, kudu, and diverse rodent communities provide prey bases. Rivers and dambos host aquatic taxa like Nile crocodile and migratory fish tied to fisheries important to riparian communities recognized in management plans by regional conservation NGOs such as Wildlife Conservation Society and World Wide Fund for Nature programs. Avifauna is rich with endemic and migratory species recorded in inventories by ornithological groups including BirdLife International.

Human inhabitants and land use

Indigenous and rural populations including groups affiliated with national identities of Bemba people, Chewa people, Lozi people, and Lunda people practice shifting cultivation, agroforestry, charcoal production, and smallholder livestock rearing; these activities intersect with commercial sectors such as mining in the Copperbelt and agricultural estates linked to companies registered in the region. Urban centers and transport corridors connect to ports and trade networks involving entities like Dar es Salaam and Lusaka, affecting land-use change. Community-based natural resource management models and joint forest management initiatives often receive technical support from international agencies including the United Nations Development Programme and bilateral donors, while customary tenure systems and national land policies in each state shape access to miombo ecosystem services such as non-timber forest products, medicinal plants, and beekeeping.

Conservation and threats

Conservation priorities focus on maintaining connectivity between protected areas, mitigating poaching associated with transnational wildlife trafficking networks, and managing fire, charcoal extraction, and agricultural expansion driven by population growth and commodity markets. Threats include habitat fragmentation from infrastructure projects funded or regulated by multilateral banks, unsustainable logging for timber and charcoal affecting tree species like Brachystegia spiciformis, and pollution from mining activities in the Katanga and Copperbelt that mobilize heavy metals into waterways. Multinational conservation efforts involve partnerships among national parks agencies, NGOs such as Conservation International and African Parks, and frameworks like the Convention on Biological Diversity, with strategies emphasizing community engagement, anti-poaching units, ecological monitoring by research institutes (e.g., regional universities and the International Union for Conservation of Nature) and integration of indigenous knowledge in adaptive management to conserve biodiversity and sustain ecosystem services.
