Most of the rivers run into the sea but not so in the case of the Okavango. This river begins timidly on the plateau of Angola and as it grows towards the southeast, and in Botswana, where it forms an inland delta that has a top surface to 15,000 square kilometers. Then gradually, the river disappears at the edge of the Kalahari Desert. Geologically, it is easy to explain because the fracture lines formed two million years ago, with the movement of tectonic plates, resulting in the basin containing the swamps of Okavango.Al extend their arms in northern Botswana. the river is squeezed between two parallel lines of fracture that form the handle of the pan from the delta.
This garden is the result of a fortuitous coincidence between local rainfall and stream of origin far away. The land surrounding the inland delta has its own station rainy season from October to March, which fertilizes the Kalahari so that animals can travel these vast tracts of land in search of pasture. However, water wells and quickly dry grass in the desert, forcing the animals to start the search for food and water. But the water finally arrived after a journey of 1500 km.
During the months of February and March, the rain falls on the highlands of Angola, this water takes almost half a year to cross the border penetrating through northern Botswana Okavango. It covers the wide prairies with a thin layer of water, renewing the vegetation. Therefore, the area enjoys two rainy seasons, his own and that provided by the river making life multiply around him.
must be said that the Okavango swamps are the largest and most fertile oasis of the entire African continent, collected daily over 22,000 liters of river water. Countless channels run through the marsh, creating a maze that is constantly changing. These marshes provide shelter to crocodiles, hippos, buffaloes and other wild animals. Here live about four hundred species of birds, including African Jacana, lapwing species that seems to walk on water when the strap through water lilies. Birds, very rare, as the slate-gray heron, also live in the Reserve Moremi Wildlife, part of the delta. when the dry season reaches the Okavango involves elephants and hippos from hundreds of miles away. These animals find water in depressions leading into the swamps.
The largest group within the marshes is the nomadic herbivores returning to the ark of moisture when the drought invade the plains. So, are easy to observe antelope the desert as the Cape oryx and springbok mixed with wetland species such as the Cob. Joining them, wildebeest and impala own prairie grass and we know that where there is abundant food hunters, leopards, cheetahs, lions, wild dogs and hyenas enjoy the benefits of this ecosystem.
Wildlife in the Okavango is the splendid isolation of the tsetse fly, the famous plague of wetlands that can cause people with the disease to domestic cattle sleep and often fatal disease called nagana. For centuries this threat kept off the site to humans. Botswana currently in the area you want to increase density and y is Delta is spraying to eliminate this insect. This could open these marshes for grazing and forever change the Okavango.
hope that a state is reached sustainable operating environment.

Few emerge years later when the great opportunity of his life proclaiming the intention to organize an expedition to Egypt for scientific and bibliographic. After arduous negotiations, the two friends got the sponsorship and good wishes of their separate administrations, thereby would forge a Franco-Tuscan expedition, which also consisted of naturalists, artists, architects came to Alexandria in 1828 with goal in Upper Egypt.
