The deeply cut sandstone mountains of the Mujib Reserve span an elevation drop of over 1,200 meters: from 900 m above sea level to 400m below sea level - the lowest ground level on Earth. As a consequence of this dramatic change in altitude and the presence of several flowing rivers, it has many different habitats, supporting a wide variety of plants and animals.
One of the most important animals in Mujib is the Nubian ibex, a large mountain goat which became threatened as a result of over-hunting. RSCN established a captive-breeding centre in the Reserve in 1989 and the initial group of 20 ibex has multiplied to over 100 animals. Over 30 of these animals have been successfully returned to the wild.
