How does marram grass work?

Marram grass (Ammophila arenaria) is a vital species for stabilizing sandy dunes due to its deep, extensive root system that binds the sand together, preventing erosion. Its leaves are adapted to withstand harsh coastal conditions, including strong winds and salt spray, allowing it to thrive in these environments. By trapping sand and promoting sediment accumulation, marram grass helps build and maintain dune structures, creating habitats for various wildlife. Additionally, its ability to tolerate drought and nutrient-poor soils makes it an essential component of coastal ecosystems.
