 Ammophila
arenaria - Marram Grass
is to be found on unstable and mobile sand dunes. It is commonly a
part of other plant communities at tops of beaches and on very sandy
coastal ground.
Marram Grass is commonly planted to help
reduce coastal
erosion and stabilise sand dunes. The tussocks have the ability to
grow back through covering sand after being buried and can withstand
sand accretion rates of up to 1 metre per year. The tussocks trap
wind-blown sand and the root and rhizome growth stabilises the mobile
dunes. It is drought tolerant, grows well above the water table, and is
tolerant of the substantial temperature fluctuations on open sand
surfaces.
Leaves & Flowers
The leaves are long and strap-like;
well adapted to avoid excessive water loss
