Ecology of inland sand dunes "nafuds" as a hyper-arid habitat, Saudi Arabia: Floristic and plant associations diversity.

Sand seas of Saudi Arabia cover about one-third of the Arabian Peninsula and are still poorly explored in scientific literature. This study aimed to address the floristic structure and association diversity of the inland sand seas in central Saudi Arabia after 20 years of protection. Twenty-three relevés were selected in Nafud Al-Urayq reserve to cover different sandy dune variations.

Loranthaceae family includes hemiparasitic members which are seen invading a wide range of commercial crops. (Desv.) Danser is very common on mango trees.
