ABSTRACT:

Nafud al-‘Urayq is one of the smaller sand seas in the central Najd region of Saudi Arabia, representing the central Nafud Bioregion. It is a narrow dune corridor running north to south. After rains, Nafud al-‘Urayq is an extremely good scenic area, where the sand dunes contrast strikingly with the surrounding mountains.Nafudal-‘Urayq is a narrow corridor of dunes,located between Lat. 25° 00'N Long. 42° 29'Ewith a length of 145 km, and a width of about 7-30 km.The study area contains about 129 plant species belonging to 103genera in 38 families. Plant communities identified from the study area include Haloxylonpersicum-Calligonumcomosum, Haloxylonsalicornicum, Acacia ehrenbergiana-Acacia tortilis, Panicumturgidum and Artemisia monosperma communities. Majority of sand dunes are dominated by monostands of Haloxylonpersicum. Annuals other than psammophytes are found mostly in iselbergs and areas between dune depressions.
