okavonga delta


                                                            Okavonga Delta 

                                                                  AFRICA

  Approximately 11 cubic kilometres flow into the delta each year. The water flows continously into the delta and drains the summer (January to February) rainfall from the Angolan highlands. A surge, that flows 1200 kilometres in a month occurs between March and June. It is during this time that the Okavango Delta is at its largest. Rapid transpiration and evaporation occur caused by the high temperatures in the region result in a cycle of rising and falling water levels. One of the only sources of water during the dry period the Okavango Delta attracts thousands of animals creating one of Africa’s greatest concentrations of wildlife.

  There is a dynamic seasonal shift of animals between the arid region that surrounds the delta and the Okavango Delta itself. During the wet season most large animals move away from the delta to take advantage of the lush grazing that surrounds it. As this grazing begins to die in the winter animals move back to the delta. A myriad of species are found within the delta including African Bush Elephant, African Buffalo, Hippopotamus, Lechwe, Topi, Blue Wildebeest, Giraffe, Nile crocodile, Lion, Cheetah, Leopard, Brown Hyena, Spotted Hyena, Greater Kudu, Sable Antelope, Black Rhinoceros, White Rhinoceros, Plains Zebra, Warthog and Chacma Baboon. Notably the endangered African Wild Dog still survives within the Okavango Delta and exihibits one of the richest pack densities in Africa.
