Much of the country is a low, sterile plain covered with sand. To the south-east is the spectacular Khor al Adaid or “inland sea”, an area of moving sand dunes surrounding a bay in the gulf. The highest point in Qatar is the Jebel Dukhan in the west. This is also the location of Qatar’s main inland oilfields. The natural gas reserves are in the sea to the north-west of the peninsula.
Within the desert biome that occupies the whole of Qatar, WWF has distinguished two ecoregions: Persian Gulf desert and semi-desert along the coast, and Arabian and Sinai desert and xeric shrublands inland.
The following habitats can be found in Qatar: mangrove swamps, sabkha (marshlands), sand dunes, Hammada desert (rocks and gravel), rocky ecosystems, and fine sand depressions.
