The Sua salt pans are one of the largest salt pans in the world. This beautiful white salt crystal came from the pink water mainly comprised of algae including cyanobacteria (Anabaena and Oscillatoria) is spread across 12,000 sq kms of Botswana’s land and is visible from space! The salt pans are found within the Kalahari Desert, and as a result of this the only vegetation found in the area are salt and drought tolerant, mainly brown grasslands and baobab trees.
Baobabs are deciduous trees which grow to enormous sizes and have branches of various shapes. They live to be thousands of years old and are adapted to living in arid areas. The reason for their ability to survive in drought stricken areas is that they can store an average of 120,000 litres of water and are known to survive for 8-10 years without rain. In cases of drought the diameter of the tree shrinks overtime, resulting from loss of water retention.
Wild animals such as elephants like to eat the bark of the baobab tree because of the water retained within, especially during the dry summer days when there is no rain or sources of water. Unfortunately, I never got to witness an elephant eating a baobab, but I did see at least 500 elephants.
