The United Arab Emirates (UAE) is situated in the south-east of the Arabian Peninsula with an area of 83,600 square km. The country is mostly desert with massive sand dunes and scattered oases, while the Hajar Mountain range is found in the north-east. Soils are generally poor in nutrients and are found in four main landforms: sand, salt flat, gravel and mountains. Keeping in view the size and nature of its habitats, the UAE has a wide diversity in its flora, which has evolved to survive in the existing harsh environment. Three books on the UAE flora have been written, which describe around 737 plant species found here. Later different botanical explorations carried out by various researchers revealed that there are many other plant species in the country, which have not been reported in the UAE flora books. If these additional species are added to those recorded as described above, then the UAE total would cross 780. To find more undocumented wild plant species, International Center for Biosaline Agriculture (ICBA) started a program to explore different regions of the country.
