Marramgräset

Marramgräset, scientifically known as *Ammophila arenaria*, is a perennial grass native to coastal regions of Europe, North Africa, and parts of Asia. It is particularly well-known for its role in stabilizing sand dunes along shorelines, earning it the nickname "dune grass." This species thrives in sandy, nutrient-poor soils where few other plants can survive, making it a key component of coastal ecosystems.

The plant features long, narrow leaves with a bluish-green hue and dense, feathery flower spikes that emerge in late summer. Its extensive root system, which includes specialized rhizomes, helps bind sand particles together, preventing erosion and facilitating the formation of stable dunes. This ecological function makes *Ammophila arenaria* crucial for protecting coastal habitats from wind and wave action.

Marramgräset is often used in coastal restoration projects due to its resilience and ability to improve soil conditions over time. However, its introduction to non-native regions can sometimes lead to unintended ecological consequences, as it may outcompete local vegetation. In some areas, it is considered an invasive species, though its benefits in natural dune stabilization are widely recognized.

Beyond its ecological importance, marram grass has historical and cultural significance, particularly in coastal communities where it has been used for thatching and other traditional purposes. Its hardiness and adaptability have also made it a subject of study in plant science, particularly in research on salt tolerance and sand stabilization techniques.
