The majority of the park is open woodland. The predominant trees are species of Burkea, Baikiaea, Pterocarpus, and Erythrophleum in the southern portion of the park, and Erythrophleum, Burkea, Julbernardia, and Guibourtia in the northern areas of the park. The spacing of the trees varies considerably from place to place. The ground is covered with sparse grass, in part due to leached sandy soil which holds little water near the surface. There are small areas of dense woodland in the north-central area of the park. Along the Cuando River are expanses of seasonally- and perennially-flooded grasslands 10-15 kilometers wide, and smaller areas along the park's other rivers. Papyrus is predominant closest to the rivers and in deeper waters, with species of Phragmites and Miscanthus common in shallower water, upstream areas, and seasonally-dry areas. The park is home to a broad variety of wildlife, including large mammals like African bush elephant , giraffe, black rhinoceros, hippopotamus, common eland, plains zebra, African buffalo, sable antelope, leopard, waterbuck, and impala. The park is home to many smaller mammals and birds, and the park's wetlands are home to migratory and resident water birds. Wildlife was diminished by poaching and over-hunting during the long Angolan Civil War. Wildlife has recovered somewhat since the end of the war, but poaching, bushmeat hunting, and land mines remain threats to its recovery. The park's many land mines kill and maim elephants, African buffalo, hippos, and other large animals. They also impede anti-poaching patrols and limit the park's potential to accommodate eco-tourism. In 2019, HALO Trust, an international NGO dedicated to removing land mines, estimated that 153 minefields remained in Luengue-Luiana and Longa-Mavinga national parks. In July 2019 the Angolan Government pledged $60 million to clear landmines in the region, which HALO and the government hope to complete by 2025.Transfrontier conservation areaThe park is part of the Kavango-Zambezi Transfrontier Conservation Area, a group of adjacent protected areas in the upper Zambezi River and Okavango basins that extend across portions of Angola, Namibia, Botswana, Zambia, and Zimbabwe. The park adjoins Zambia's Sioma Ngwezi National Park across the Cuando River to the east, and Bwabwata National Park to the south in Namibia.
History
During the colonial period, hunting reserves were established in the region. The area saw little fighting during the 1961-1974 Angolan liberation war. However the region was the scene of fighting during the 1975-2002 Angolan Civil War. The combatants placed thousands of land mines in the park, and many still remain. In September 2019 Prince Harry visited the park and spoke to the urgent importance of removing land mines from the region, and praised the government's recent commitment of funds to land mine removal. The park was created in 2011, by National Assembly Decree which proclaimed the Luengue-Luiana and Mavinga national parks. The new park includes the former Luiana and Mucusso reserves. The park is governed by the Ministry of Hotels and Tourism.
