The Okavango delta is both a permanent and seasonal home to a wide variety of wildlife.

Species include African Bush Elephant, African Buffalo, Hippopotamus, Lechwe, Topi, Blue Wildebeest, Giraffe, Nile crocodile, Lion, Cheetah, Leopard, Brown, Spotted Hyena, Greater Kudu, Sable Antelope, Black, White Rhinoceros, Plains Zebra, Warthog and Chacma Baboon can be found here.

Notably the endangered African Wild Dog still survives within the Okavango Delta. The delta also includes over 400 species of birds, including African Fish Eagle, Crested Crane, Lilac-breasted Roller, Hammerkop, Ostrich, and Sacred Ibis.

The majority of the estimated 200,000 large mammals in and around the delta are not year round residents. They leave with the summer rains to find renewed fields of grass to graze on and trees to browse, then make their way back as winter approaches. Large herds of buffalo and elephant total about 30,000 beasts.

The plants of the Delta play an important role in providing cohesion for the sand. The banks or levees of a river normally have a high mud content and this combines with the sand in the river’s load to continuously build up the river banks. In the Delta, because of the clean waters of the Okavango, there is almost no mud and the river’s load is comprised almost entirely of sand. The plants capture the sand, acting as the glue and making up for the lack of mud and in the process creating further islands on which more plants can take root.

This process is important in the formation of linear islands. They are long and thin and often curved like a gently meandering river. The reason for that is that they are actually the natural banks of old river channels which over time have become blocked up by plant growth and sand deposition, resulting in the river changing course and the old river levees becoming islands. Due to the flatness of the Delta, and the large tonnage of sand flowing into it from the Okavango River, the floor of the delta is slowly but constantly rising. Where channels are today, islands will be tomorrow and then new channels may wash away these existing islands.
