The Mujib Biosphere Reserve is the lowest nature reserve in the world, with a spectacular array of scenery near the east coast of the Dead Sea. The Reserve is located within the deep Wadi Mujib gorge, which enters the Dead Sea at 410m below sea level. The Reserve extends to the Karak and Madaba mountains to the north and south, reaching 900 metres above sea level in some places. This 1,300m variation in elevation, combined with the valley's year- round water flow from seven tributaries, means that Wadi Mujib enjoys a magnificent bio-diversity that is still being explored and documented today. Over 300 species of plants, 10 species of carnivores and numerous species of permanent and migratory birds have been recorded. Some of the remote mountain and valley areas are difficult to reach, and thus offer safe havens for rare species of cats, goats and other mountain animals. Mujib's sandstone cliffs are an ideal habitat for one of the most beautiful mountain goats in the world, the horned Ibex.
