In 1977, the president, Sheikh Zayed, started developing his wildlife preserve and called this project "Greening of the Desert". This programme' sole purpose was to make the desert more suited for human colonisation and make it a wildlife preserve for the endangered animals of Arabia. With this objective in mind, millions of trees were grown, and many species of animals introduced. From Somali ostrich, gazelles, Arabian oryx, giraffes, sea turtles, to dolphins, all can be viewed in this wildlife preserve. That's not it, more than 100 wild bird species are native to the place. Moreover, around thirty mammal species can be found here. Take the Arabian onyx, these were pretty much non-existent in the wilderness, but you'll be able to witness around 400 of these fascinating creatures running around on the island. Around half of the island allows these animals to wander freely without any restrictions. The island welcomes visitors from all over the world to come to see its wildlife magnificence.
