Species like sewan grass are very important in arid environments because they provide forage, which maintains both wild mammals and livestock, and soil cover (Assaeed, 1997). Reseeding arid rangelands with species such as Lasurius scindicus, which are more palatable than native species, would improve the forage resource (Khan et al., 1999). Sewan grass can be used to stabilize desert sandy dunes (Ecocrop, 2010; FAO, 2010).
In deteriorated rangelands of Saudi Arabia, sewan grass helps to control the low value invasive species Rhazya stricta by smothering its seedlings. It is a useful tool to improve rangeland management (Assaeed et al., 2001).
