The Tree of Life in Bahrain is an approximately 400-year-old, 9.75 m high Prosopis cineraria tree located 2 km from Jebel Dukhan and abundantly covered in green leaves.The tree stands on a hill in the Arabian Desert surrounded by miles of sand. There is not another tree for as far as is visible, nor any other life forms. The average temperature in the region is 41°C, often rising to 49°C, and sandstorms are common.It is not certain how the tree survives. Scientists have speculated that the nearest possible source of water is an underground stream about two miles away and that the tree is somehow drawing water from that stream. Others say the tree has learned to extract moisture from breezes blowing it from the Persian Gulf or squeeze moisture from grains of sand. Others claim that the tree is standing in what was once the Garden of Eden, and so has a more mystical source of water.Tourist attractionThe tree is a local tourist attraction, as it is the only major tree growing in the area. The tree is visited by approximately 50,000 tourists every year. It is very popular because it is believed to be growing in the middle of nowhere, with no water source and has never been watered once throughout history. Bahrain also has little to no rain throughout the year. As a result, it is also believed to be the site for cults practising ancient rites. In October 2010, archaeologists unearthed 500-year-old pottery and other artifacts in the vicinity of the tree. A soil and tree ring analysis conducted more than 20 years ago concluded that the Tree of Life was an Acacia planted in 1582.
