Marram grass

Enw gwyddonol: Ammophila arenaria
The dense, spiky tufts of Marram grass are a familiar sight on our windswept coasts. In fact, its matted roots help to stabilise sand dunes, allowing them to grow up and become colonised by other species.

Ynghylch

The dense, grey-green tufts of Marram grass are a familiar feature of our coastal sand dunes, its spiky leaves featuring in many games during long summer picnics at the beach. But Marram grass is not just a convenient child's sword or hiding place, it plays a vital role in stabilising the dunes, its fibrous, matted roots binding the sand down, which helps to encourage the colonisation of other plants. Well-adapted to a harsh life at the coast, its glossy, rolled-up leaves protect it from drying out.; it flowers in July and August.

Habitats

Roeddech chi yn gwybod?

Marram grass was once harvested and weaved into mats for barn roofs, nets for fishing and even shoes. Traditionally, each family had its own sand dune, but the whole village would often be involved in collecting the grass. Today, the importance of Marram Grass in stabilising these fragile habitats has curbed its harvesting.
