The Mongolian government established the Great Gobi National Park in 1975 and the UNESCO designated as the Great Gobi as the fourth largest Biosphere Reserve in the world in 1991. Mongolians consider that there are 33 different Gobi , where sandy desert occupies only 3 percent of the total territory. The area is often imagined as a lifeless desert like in many other parts of the world. Gobi Desert is a land of dinosaurs and it is the home for camel breeders rich with wildlife and vegetation. Dinosaur skeletons and their petrified eggs have been preserved here to the present day. Wild asses, camels, snow leopards, mountain sheep and gazelles flourish here, as do different types of flora.
