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.
See Box and Tables 2 and 3 for key species. Mkuzi Game Reserve supports c.420 species of birds, the richest area for its size in the whole of South Africa. The Ediza–Hlonhlela–Nsumo pans comprise a very diverse mosaic of open water, marsh, flood-plain and wet grasslands and, in terms of diversity of habitats and potential for waterbirds, constitute a highly significant wetland system. The pans regularly support more than 20,000 waterbirds and certain species almost certainly aggregate in numbers that exceed the 1% threshold, although not enough detailed data are available to show this.Nsumo Pan is the only regular breeding locality for Pelecanus rufescens in South Africa. Several other species occur at the pan in good numbers, including Anastomus lamelligerus, Mycteria ibis (which breeds in most years, with up to 50 nests), and Chlidonias hybridus. The fig forest supports small populations of Scotopelia peli, Circaetus fasciolatus, Podica senegalensis and Gorsachius leuconotus. The Mkuze Gorge holds a small colony of Geronticus calvus, which forage primarily in grassland habitat outside the reserve, as the vegetation within Mkuzi is unsuitable. As one of the larger reserves in South Africa it holds populations of larger scavengers and terrestrial species, numbers of which have dwindled outside South Africa’s protected-area network. Mkuzi is a stronghold for Gyps africanus, holding perhaps 200 nesting pairs. It also holds small populations of Torgos tracheliotus, Trigonoceps occipitalis, Polemaetus bellicosus, Terathopius ecaudatus, Aquila rapax, Leptoptilos crumeniferus, Ciconia nigra, Ephippiorhynchus senegalensis and Bucorvus cafer. Gyps coprotheres, which breed elsewhere, are occasionally seen foraging in the reserve, particularly young non-breeding birds.
Non-bird 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.
