How is marram grass adapted to withstand damage by wind-blown sand?

Marram grass is well-adapted to withstand damage from wind-blown sand due to its deep, extensive root system, which anchors it firmly in the sandy substrate. Its long, narrow leaves are designed to bend in the wind rather than break, reducing the impact of abrasive sand particles. Additionally, the grass has a tough, waxy coating on its leaves that helps to minimize water loss and protect against sand abrasion. This combination of features enables marram grass to thrive in harsh, coastal environments where sand movement is prevalent.
