Sand dune vegetation consists of plants that have adapted to thrive in sandy, often harsh environments. These plants, such as sea oats and beach grass, play a crucial role in stabilizing the dunes by trapping sand with their roots. Their ability to tolerate salt spray and shifting sands allows them to survive in coastal areas. The vegetation also provides habitat for various wildlife, including birds and insects. By creating a protective barrier, sand dune plants help prevent erosion and maintain the integrity of coastal ecosystems. Their presence is vital for the health of both the dunes and the surrounding environment.
