Oryx, giraffes and cheetahs roam an "Arabian Ark" nature reserve on a desert Gulf island where species once facing extinction in the region are making a comeback. Since animals were first brought to Sir Bani Yas off the coast of Abu Dhabi more than four decades ago, their total population has soared to more than 13,000. Twenty-five species of mammals and 170 types of birds are found in a nature reserve covering an area of 1,400 hectares (3,500 acres). Some species are, or were, endangered in the region, or even extinct in the wild.
