Nkasa Rupara National Park, also Nkasa Lupala National Park, formerly Mamili National Park, is a national park in Namibia.
It is centered on the Nkasa and Rupara islands on the Kwando/Linyanti River in the south-western corner of East Caprivi. Botswana lies to the west, south and east, and Sangwali village to the north.
It is Namibia’s largest formally protected wetland area. It is one of Namibia’s protected areas that benefits local communities surrounding parks. The unfenced park forms a trans-boundary link for wildlife migration between Angola, Botswana, Namibia and Zambia.
Nkasa Rupara is part of the Kavango Zambezi Transfrontier Conservation Area (KaZa TFCA).
History
Mamili National Park was officially proclaimed along with the nearby Mudumu National Park on 1 March 1990. In 2012, the Namibian Government renamed the area as Nkasa Rupara National Park.
The former name, Mamili, referred to a family of traditional leaders of the Mafwe tribe with that surname. The new name, Nkasa Lupala, is a reference to two Kwando River islands within the park’s territory.
Geography and access
The Kwando River runs along Nkasa Rupara’s western border and then changes course to become the Linyanti River, forming the park’s south-eastern boundary. It is the same river but is known by different names in various areas.
The northern border abuts the Balyewa, Wuparo and Dzoti communal area conservancies the entire area is flat. Most of the park consists of channels of reed beds, lagoons and islands.
Nkasa Rupara has relatively narrow, permanently filled main channels of the Kwando/Linyanti River and several periodically flooded channels. The river has its catchment area in Angola and flooding regimes vary considerably.
This results in flooding in some years and dry spells during others. To access Nkasa Rupara National Park turn off the B8 Trans-Caprivi Highway, onto the D3511 after the Kongola Bridge.
The only entrance track crosses a bridge over a back-channel of the Kwando/Linyanti River, near Sangwali village in Wuparo Conservancy. Rupara Island is reached via a dirt track; Nkasa Island in not reachable because the access is flooded.
Climate
Rainfall: 600 millimetres (24 in) – 700 millimetres (28 in) per annum (variable). Temperature: 5 °C (41 °F) – 35 °C (95 °F).
Biology and ecology
Nkasa Rupara National Park contains Namibia’s most extensive wetlands, marshes and seasonally inundated areas. Ecosystem types are similar to the Okavango Delta wetlands and habitats.
Periodic flooding drives the park’s ecosystem. Caprivi floodplains dominate. Various trees are found on small islands consisting of old termite mounds (ant hills) known as termitaria.
Flora
Nkasa Rupara is found in the broadleaved tree and wood savanna biome; vegetation type is Caprivi floodplains. Woody vegetation is found on higher islands that are rarely flooded.
Examples of common woodland species are knob thorn (Acacia nigrescens), paper-bark acacia (Acacia sieberiana), large-leaved albizia (Albizia versicolor), monkeybread (Piliostigma thonningii), leadwood (Combretum imberbe), sausage tree (Kigelia africana) and silver cluster-leaf (Terminalia sericea).
Fauna
Nkasa Rupara forms a corridor for all large mammal species moving between Namibia and Botswana, particularly African elephant and buffalo. There are about 1 000 buffalo in Nkasa Rupara, the largest concentration in Namibia.
Around 560 hippopotami and 500 crocodile occur in the park’s rivers and channels Rare antelope species include sitatungas, pukus, red lechwe, reedbucks and oribis.
Mammals of this park as well as reptiles feature elephants, lions, Namibian cheetahs, leopards, spotted hyenas, Cape wild dogs, roan antelopes, impala, kudus, warthogs, baboons, spotted-necked otters, rock monitor lizards and water monitor lizards.
About 450 bird species have been counted. Several rare, vulnerable and endangered species are found here, such as wattled crane, Pel’s fishing-owl, black-cheeked lovebird and yellow-billed oxpecker.
Other birds are Stanley’s bustard, rosy-throated longclaw, Dickinson’s kestrel, Allen’s gallinule, lesser jacana, black-winged and red-winged pratincole, long-toed lapwing, Luapula cisticola, coppery-tailed coucal and black coucal.
Fires
Lightning or human-caused fires occur seasonally. They are important for the park’s ecology, regulating the dominance of tall grass stands and keeping woody plants at bay.
Recreation
At least two all-wheel drive vehicles are needed as the terrain can be muddy and waterlogged. Nkasa Rupara is situated in a malaria area. Park fees must be either pre-paid at the Ministry of Environment and Tourism (MET) offices in Katima Mulilo, Windhoek or upon arrival.
Nkasa Rupara has minimal facilities. There are no shops, filling stations or other facilities in the park. Visitors must be self-sufficient. There is a community camp-site on the park’s northern border.
The Nkasa Lupala tented lodge was built recently as part of a tourism concession granted by the Namibian Government. It is a partnership with the Wuparo Conservancy. Wuparo Conservancy also runs a community campsite outside the park.
