摘要：The Coastal dunes of the Mediterranean Eastern Morocco show a large floristic and faunistic biodiversity and represent a national heritage of a great value at the ecological, socio-economic and eco-touristic levels. On the morpho-anatomical level, marram grass (Ammophila arenaria L.), a typical granimeous plant of the coastal dunes, is well adapted to its biotope. Thanks to its high adaptations, this xerophyte and halophyte plays several ecological roles the most important of which is the fixing of sand. On the physiological level, the optimum germination temperature of seeds in distilled water is 20°C. This culture in vitro makes it possible to obtain a large number of marram grass seedlings which could be used for the restoration, and the rehabilitation of the degraded dunes. The coastal dunes of the Mediterranean Eastern Morocco are currently under an intense anthropic pressure which threatens their ecological balance and their biodiversity. In absence of the littoral rights and a plan of integrated management, which ensures a sustainable development in these coastal areas, the anthropic pressures can only increase and the evolution of the dune ecosystem can only regress.
