Baobab tree in Senegal

A typical scene in northern Senegal. Baobab trees are common in Africa (1 species), Madagascar (6 species) and Australia (1 species). It also commonly referred to as bottle tree or upside down tree. Baobabs store water inside the swollen trunk (up to 120,000 litres) to endure the harsh drought conditions. All occur in seasonally arid areas, and shed their leaves during the dry season. Some baobabs are reputed to be many thousands of years old, which is difficult to verify as the wood does not produce annual growth rings,
