In the upper Congo River Basin in north-eastern Zambia lies one of Africa's greatest wetland systems – Bangweulu Wetlands. Bangweulu is a local word meaning "where the water meets the sky” reflecting the vast, seasonally inundated stretches of untouched wilderness. The broader Bangweulu system includes Lake Bangweulu and other adjoining smaller lakes, floodplains and swamps, termitaria woodlands and extensive areas of pristine Miombo woodland to be found adjacent to the seasonally flooded grassland. The Chambeshi and Luapula Rivers, which are the main southern tributaries of the massive Congo River rise in the area. Bangweulu is home to considerable numbers of the endemic black lechwe with a current estimate of more than 75,000 animals. It is also an important breeding area for the shoebill, one of Africa's enigmatic ornithological assets.
