However, water is still an essential resource for dune vegetation. Sand dunes begin to form when sand is blown inshore from a beach. The sand is trapped by obstacles such as pebbles, seaweed or semi-halophytic plant species such as sea rocket and prickly saltwort on the strand line. Water plants have no problem of water shortage. The long roots of Marram grass help it to find water deep in the sand, and bind the sand together in dunes. Hence, legislation promoting dune stabilization came into force in 1779 and 1792, successively leading to a system of state-supported dune planters overlooked by dune bailiffs. Tolerant of accretion rates of up to 1m/yr. It also includes Saltwort Salsola kali. Many halophyte plants have tiny leaves. These adaptations result in humid air becoming trapped inside the rolled leaf, reducing the rate of transpiration. Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. Their native range includes few inland regions, with the Great Lakes of North America being the main exception. Advertisement.

STAY. [3] The genus name Ammophila originates from the Greek words ἄμμος (ámmos), meaning "sand", and φίλος (philos), meaning "friend". Halophyte leaves are excellent at counter-acting the desiccating effects of salt. In the semi-fixed dunes (community SD7), where the quantity of blown sand is declining Ammophila becomes less competitive, and other species, notably Festuca rubra (red fescue) become prominent. The inner layer has hairs to trap water vapour. Marram grass and cacti both have this adaptation as marram grass has micro hairs in the stomata pits and cacti normally have spines which are hairy.
