from May to October for large breeding herds of African bush elephants, families of Angolan giraffe, sable antelope and African buffalo. The floodplains are the only place in Botswana where the puku antelope can be seen. Large numbers of southern carmine bee-eaters are spotted in season. When in flood, African spoonbills, ibis, various species of storks, ducks and other waterfowl flock to the area. This is likely Chobe's most visited section, in large part because of its proximity to the Victoria Falls, Zambia. The town of Kasane, situated just downstream, is the most important town of the region and serves as the northern entrance to the park. The Savuti Marsh area, large, constitutes the western stretch of the park ( north of Mababe Gate). The Savuti Marsh is the relic of a large inland lake whose water supply was cut a long time ago by plate tectonicss. Nowadays the marsh is fed by the erratic Savuti Channel, which dries up for long periods, then curiously flows again as a consequence of tectonic activity in the area. It is currently flowing again and in January 2010 reached Savuti Marsh for the first time since 1982. As a result of this variable flow, there are hundreds of dead trees along the channel's bank. The region is also covered with extensive savannahs and rolling grasslands, which makes wildlife particularly dynamic in this section of the park. During dry seasons, both black and white rhinoceros, warthog, greater kudu, impala, Burchell's zebra, blue wildebeest and a herd of elephants are seen. During rain seasons, the rich birdlife of 450 species is represented. Prides of lions, hyenas, zebras or more rarely Southeast African cheetahs are sighted as well. This region is reputed for its annual migration of zebras and predators. The Linyanti Marsh, located at the northwest corner of the park and to the north of Savuti, is adjacent to the Linyanti River. To the west of this area lies Selinda Reserve and on the northern bank of Kwando River is Namibia's Nkasa Rupara National Park. Around these two rivers are riverine woodlands, open woodlands as well as lagoons, and the rest of the region mainly consists of flood plains. There are large concentrations of lion prides, African leopard, African wild dog, roan antelope, sable antelope, a hippopotamus pod and herds of African bush elephant. The rarer red lechwe, sitatunga and a bask of Nile crocodiles
