The Selous Game Reserve: A Haven for African Biodiversity

The Selous Game Reserve, now officially known as the Nyerere National Park, is a sprawling expanse of pristine wilderness located in southern Tanzania, East Africa. Established in 1922, it was designated a UNESCO World Heritage Site in 1982 due to its exceptional biodiversity and extensive, untouched natural landscapes. Covering an area of approximately 50,000 square kilometers, the park serves as a vital refuge for countless African wildlife species, making it one of the largest protected areas in Africa.

UNESCO Description of the World Heritage Site

Large numbers of elephants, black rhinoceroses, cheetahs, giraffes, hippopotamuses and crocodiles live in this immense sanctuary, which measures 50,000 km² and is relatively undisturbed by human impact. The park has a variety of vegetation zones, ranging from dense thickets to open wooded grasslands.

UNESCO Justification of the World Heritage Site

Criterion (ix): The Selous Game Reserve is one of the largest remaining wilderness areas in Africa, with relatively undisturbed ecological and biological processes, including a diverse range of wildlife with significant predator/prey relationships. The property contains a great diversity of vegetation types, including rocky acacia-clad hills, gallery and ground water forests, swamps and lowland rain forest. The dominant vegetation of the reserve is deciduous Miombo woodlands and the property constitutes a globally important example of this vegetation type. Because of this fire-climax vegetation, soils are subject to erosion when there are heavy rains. The result is a network of normally dry rivers of sand that become raging torrents during the rains; these sand rivers are one of the most unique features of the Selous landscape. Large parts of the wooded grasslands of the northern Selous are seasonally flooded by the rising water of the Rufiji River, creating a very dynamic ecosystem.

Criterion (x): The reserve has a higher density and diversity of species than any other Miombo woodland area: more than 2,100 plants have been recorded and more are thought to exist in the remote forests in the south. Similarly, the property protects an impressive large mammal fauna; it contains globally significant populations of African elephant (Loxodontha africana) (106,300), black rhinoceros (Diceros bicornis) (2,135) and wild hunting dog (Lycaon pictus). It also includes one of the world's largest known populations of hippopotamus (Hippopotamus amphibius) (18,200) and buffalo (Syncerus caffer) (204,015). There are also important populations of ungulates including sable antelope (Hippotragus niger) (7000), Lichtenstein's hartebeest (Alcelaphus lichtensteinii) (52,150), greater kudu (Tragelaphus strepsiceros), eland (Taurotragus oryx) and Nyassa wildebeest (Connochaetes albojubatus) (80,815). In addition, there is also a large number of Nile crocodile (Crocodilus niloticus) and 350 species of birds, including the endemic Udzungwa forest partridge (Xenoperdix udzungwensis) and the rufous winged sunbird (Nectarinia rufipennis). Because of this high density and diversity of species, the Selous Game Reserve is a natural habitat of outstanding importance for in-situ conservation of biological diversity.

Encyclopedia Record: Selous Game Reserve

The Selous Game Reserve, now renamed as Nyerere National Park (in-part), is a protected nature reserve and wilderness area in southern Tanzania, East Africa. It covers a total area of 50,000 km2 (19,000 sq mi), with additional buffer zones, as well. It was designated a UNESCO World Heritage Site in 1982, owing to its high levels of biodiversity and vast, undisturbed natural landscapes, such as the grasslands and the miombo woodlands habitat. Among the numerous species within the park are some of the continent's largest and most iconic, such as the bush elephant, black rhinoceros, hippopotamus, lion, leopard, spotted hyena, painted dog, Cape buffalo, Masai giraffe, plains zebra, white-bearded gnu and the giant Nile crocodile. Due to the fragility and sensitivity of the many species and ecosystems within the park, human habitation is not permitted within its bounds, and all persons entering and exiting are tallied and tracked by the Wildlife Division of the Tanzanian Ministry of Natural Resources and Tourism.
