Wildlife of the United Arab Emirates
The wildlife of the United Arab Emirates is the flora and fauna of this country on the eastern side of the Arabian Peninsula and the southern end of the Persian Gulf. The country offers a variety of habitats for wildlife including the coast, offshore islands, mangrove areas, mudflats, salt pans, sand and gravel plains, sand dunes, mountain slopes, wadis and rocky summits. Because the terrain is so varied, it supports a greater number of species of plants and animals than might have been expected in this relatively small country.

Geography
The United Arab Emirates occupy a corner of Arabia bounded by Saudi Arabia to the west and south, Oman to the east, the Gulf of Oman and Oman to the northeast and the Persian Gulf to the north. The northern coast stretches for about 650 km (400 mi) along the southern shore of the Persian Gulf and largely consists of salt pans that extend inland. There are numerous offshore islands, the ownership of some of which is disputed with neighbouring states. To the south is the Rub' al Khali desert, an enormous expanse of billowing sand dunes. Two large oases in the east are the Liwa Oasis, near the undefined border with Saudi Arabia, and Al-Buraimi Oasis at Al Ain. To the east the land rises and becomes mountainous, this being the northern end of the Al Hajar Mountains. Beyond these, the coast on the Gulf of Oman is rugged.[1]
In the southeast of the country, near the border with Oman, there is a man-made lake, Lake Zakher, formed as a result of the release of waste water from the desalination plants on which the UAE relies for its freshwater supplies. The lake has formed as the groundwater rose, and many birds now visit the lake.[2]
Flora
A wide range of plants is associated with the many types of habitat in the United Arab Emirates. One of these types is sabkha, an area in which salty water has flooded the land shallowly and later evaporated, leaving crusty salt pans. These occur on the western part of the Gulf Coast but also among dunes inland. The plants found on their edges are salt-tolerant members of Salicornioideae and Zygophyllum. At inland sites Zygophyllum qatarense predominates along with grasses such as Aeluropus lagopoides and Panicum turgidum.[3] Sandy plains further east along the coast from the sabkha region have occasional dwarf tamarisk trees and such plants as Salsola imbricata and Zygophyllum mandavillei, and in coastal lagoons, and in creeks further east, the white mangrove is plentiful.[4]
Plants of the gravel plains further east again include Cornulaca monacantha, Crotalaria persica, Calotropis procera and Taverniera spartea, and the parasitic desert hyacinth and the desert thumb. As the land rises up towards the mountains, the mesquite tree, an invasive species from Central America, has become established. The plains around Ras al-Khaimah in the northeast of the country, between the mountains and the sea, are the most heavily cultivated part of the country. The mountains have a cooler, more temperate climate and here there is an abundance of Alpine flowers among the rocks, on slopes and in cracks, fissures and wadis.[4]
Fauna
Over four hundred species of bird have been recorded in the United Arab Emirates, with about ninety species breeding regularly in the country while the balance are winter visitors, migrants or vagrants. The country is on the crossroads of two major migratory routes, one between the Palaearctic and Africa, the other between the Near East and the Indian subcontinent, and the migrants make use of the many types of habitat available.[5]
About 250,000 waders visit the Gulf shores and mudflats at peak migration time; these include the grey plover, the greater and lesser sand plovers, the crab plover, the Kentish plover and the broad-billed sandpiper. The coast, and particularly offshore islands are used by many seabirds. About twenty to thirty percent of the world's Socotra cormorants, about 200,000 birds, breed in the United Arab Emirates, but they are under threat from fishermen who fear for their livelihoods. Sooty gulls breed here, as do red-billed tropicbirds as well as several species of tern; white-cheeked, bridled and lesser crested tern.[5]
A large number of passerine birds breed in the deserts, salt flats, plains, dunes and mountains. Twelve species of wheatear have been recorded in the country as well as warblers, babblers, rollers, bulbuls, the desert lark and many others. The sooty falcon overwinters in Madagascar and breeds in the United Arab Emirates. Other than this, there are only a small number of raptor species; Bonelli's eagle, barbary falcon, short-toed snake eagle, long-legged buzzard and lappet-faced vulture.[5]
Many of the large mammals found in the Arabian Peninsula were well-adapted to desert life in the harsh terrain, but were wiped out by human hunting in the last hundred years or so. Hunting is now banned in the United Arab Emirates, but feral goats and donkeys are plentiful and graze indiscriminately, lessening the chance for the native gazelles to recover from their reduced population sizes. Large terrestrial mammals still found in the United Arab Emirates include the Arabian tahr, the Arabian oryx, the sand gazelle and the mountain gazelle.[6] Carnivores include the Arabian wolf, the striped hyena, the red fox, the Blanford's fox, the Rüppell's fox, the caracal, the Arabian wildcat, the sand cat and the Arabian leopard. Other mammals include the Cape hare, the Brandt's hedgehog, the desert hedgehog and the long-eared hedgehog.[6]
The Egyptian fruit bat is found here during most of the year, but moves around according to the availability of fruit. Insectivorous bats include the sac-winged bat, the mouse-tailed bat and the leaf-nosed bat. Small rodents include the lesser Egyptian jerboa, the Cheesman's gerbil and the Balochistan gerbil.[6] Rather larger rodents are the Libyan jird and the Sundevall's jird which both favour desert habitats. The Cairo spiny mouse was found in the mountains for the first time in 1995.[6]
Over 54 species of terrestrial reptile have been recorded in the UAE. These include a large number of lizards, found in all environments from desert, to city, to mountain-top, and a single species of worm lizard. There are thirteen species of terrestrial snake, some of the largest being the sand boa, the saw-scaled viper and the horned viper, and four species of sea snake as well as green sea turtles present in the Persian Gulf. There are two species of amphibian in the United Arab Emirates, the Arabian toad and the Dhofar toad; the former is more commonly seen as the Dhofar toad is nocturnal.[7]
