Site description Mkuzi Game Reserve is situated on the subtropical Mozambique coastal plain, c.330 km north of Durban and c.110 km north of Mtubatuba. The topography of the area is mainly flat or gently undulating, and is intersected by seasonal drainage lines alternating with low ridges. The western sector, which comprises the foothills of the Lebombo mountains, is rugged. The Mkuze river flows through an impressive gorge in the Lebombo mountains; the lower end of the gorge is located within the reserve.

The terrestrial vegetation is mainly lowveld of the tropical bush savanna, and is exceptionally diverse. The tall tree-savanna in the Lebombo mountains is characterized by Combretum, with grass dominating the understorey. Clay soils tend to be dominated by Acacia woodland, with associated Dichrostachys. Thickets on poorly drained, heavy black soils, are dominated by Acacia and Euclea, with occasional emergent trees of Spirostachys, Schotia, Pappea, Sideroxylon and Berchemia. Sandy soils support a completely different woodland, of Combretum, Acacia, Sclerocarya, Ziziphus and Terminalia.

The Tongoland sand-forest, around Kubube and Kumasinga hides, is a very specialized vegetation-type, unique to northern KwaZulu-Natal and southern Mozambique, which occurs in parallel strips on the white sandy soils of the fossil dunes. The canopy (up to 10 m high) is dominated by Newtonia, Cleistanthus, Dialium, Strychnos and Pteleopsis. There is a discontinuous subcanopy tree layer, and a well-developed shrub layer, but the substratum is poorly developed. Lianas are present.

The fig forest surrounding Nsumo Pan and the riverine forest adjacent to the banks of the Mkuze river are well developed and are dominated by Ficus and Trichilia; associated trees are Rauvolfia, Celtis, Blighia and Acacia. Flood-plain grasslands occur on seasonally inundated flats adjacent to the Mkuze and Msunduzi rivers. Characteristic plants are reed Phragmites, sedge Cyperus and grasses (Echinochloa, Eriochloa, Sorghum). The major pans, particularly Nsumo Pan, are nutrient-rich and characterized by floating vegetation such as Nymphaea, Nymphoides, Potamogeton and Trapa.

Other biodiversity Among plants, the Lebombos support many rare species, including the cycads Encephalartos ngoyanus and E. lebomboensis, as well as Pachypodium saundersii, Hemizygia ramosa, Pachycarpus lebomboensis and Polystachya zuluensis, while low-lying grassland holds Rhus kwazuluana, and the sand-forest holds Combretum mkuzense (LR/nt). Large mammals are well represented, and include Ceratotherium simum (LR/cd), Diceros bicornis (CR) and Acinonyx jubatus (VU); Loxodonta africana (EN) have recently been reintroduced to Mkuzi.
