Sultanate of Oman Geography

A vast gravel desert plain covers most of central Oman, with mountain ranges along the north (al Jebel al Akhdar) and southeast coast, where the country's main cities are also located: the capital city Muscat, Matrah and Sur in the north, and Salalah in the south. Oman's climate is hot and dry in the interior and humid along the coast. During past epochs Oman was covered by ocean. Fossilized shells exist in great numbers in areas of the desert away from the modern coastline. The peninsula of Musandam (Musandem), which has a strategic location on the Strait of Hormuz, is separated from the rest of Oman by the United Arab Emirates and is thus an exclave. The series of small towns known collectively as Dibba are the gateway to the Musandam peninsula on land and the fishing villages of Musandam by sea. Boats may be hired at Khasab for trips into the Musandam peninsula by sea. Oman has one other exclave, inside UAE territory, known as Madha. It is located halfway between the Musandam Peninsula and the rest of Oman.[7] Belonging to Musandam governorate, it covers approximately 75 km² (29 sq mi). The boundary was settled in 1969. The north-east corner of Madha is closest to the Fujairah road, barely 10 m (32.8 ft) away. Within the exclave is a UAE enclave called Nahwa, belonging to the Emirate of Sharjah. It is about 8 km (5 mi) on a dirt track west of the town of New Madha. It consists of about forty houses with its own clinic and telephone exchange.[8]

[edit] Climate
Annual rainfall in Muscat averages 10 cm (4 in), falling mostly in January. Dhofar is subject to the southwest monsoon, and rainfall up to 64 cm (25 in) has been recorded in the rainy season from late June to October. While the mountain areas receive more plentiful rainfall, some parts of the coast, particularly near the island of Masirah, sometimes receive no rain at all within the course of a year. The climate generally is very hot, with temperatures reaching 54°C (129°F) in the hot season, from May to September.

[edit] Flora and fauna
Desert shrub and desert grass, common to southern Arabia, are found. Vegetation is sparse in the interior plateau, which is largely gravel desert. The greater monsoon rainfall in Dhofar and the mountains makes the growth there more luxuriant during summer. Coconut palms grow plentifully in Dhofar and Frankincense grows in the hills. Oleander and varieties of Acacia abound.
Indigenous mammals include the Leopard, Hyena, Fox, Wolf, and Hare, Oryx, Ibex, Tahr. Birds include the Vulture, Eagle, Stork, Bustard, Arabian Partridge, Bee Eater, Falcon and Sunbird.

[edit] Environment
Maintaining an adequate supply of water for agricultural and domestic use is Oman's most pressing environmental problem. The nation has limited renewable water resources, with 94% used in farming and 2% for industrial activity. Drinking water is available throughout the country, either piped or delivered. Both drought and limited rainfall contribute to shortages in the nation's water supply. The nation's soil has shown increased levels of salinity. Pollution of beaches and other coastal areas by oil tanker traffic through the Strait of Hormuz and Gulf of Oman is also a persistent problem. In 2001, the nation had nine endangered species of mammals and five endangered types of bird. Nineteen plant species are also threatened with extinction. Decrees have been passed to protect endangered species, which include the Arabian Leopard, Arabian oryx, mountain gazelle, goitered gazelle, Arabian tahr, green sea turtle, hawksbill turtle and olive ridley turtle. In 2007 Oman's Arabian Oryx Sanctuary became the first site ever deleted from UNESCO's World Heritage list because of the government's decision to reduce the site to 10% of its former size.[9]
