Description & Remarks

The most important dwarf shrub of the sand vegetation in the coastal sands, the Western Negev, and N Sinai. It germinates after perennial grasses adapted to high sand mobility (Ammophila arenaria in the coastal plain and Stipagrostis scoparia in the desert sands) arrested the free sand mobility. A. monosperma resists branch coverage by sand by producing shoot-borne roots, thus enabling fast growth of new branches above the sand cover. In sites with mobile sand where A. monosperma grows, “nebkas” (biogenic hills) develop as a result of the plant growth above the sand covering it. Such nebkas may become 5 m above the “physical” dune surface. A. monosperma plants may resist sand deflation by its corcky bark protecting the exposed roots from desiccation. When stands dominated by this plant become densely populated, sand mobility stops and the sand become enriched by airborne dust and by humus. The amelioration of moisture and nutrient regime bring about increasing species diversity and successional changes leading to sand stabilization.
