Grey dunes are a type of coastal sand dune characterized by their well-developed vegetation and a distinct greyish appearance due to the accumulation of organic matter and the presence of specific plant species. They typically form inland from active sand dunes and are stabilized by grasses and shrubs, which help prevent erosion. Grey dunes play a crucial role in coastal ecosystems, providing habitat for various flora and fauna, and acting as a buffer against coastal erosion. Their ecological importance makes them a focus for conservation efforts in many coastal areas.
