The primary reason for the protection of sea oats and sea grapes lies in their critical ecological role, particularly in preventing soil erosion and promoting dune establishment. Sea oats, in particular, have deep root systems that stabilize sandy soils on coastal dunes, which helps to maintain the integrity of these areas against the forces of wind and water. This stabilization is crucial not only for preserving the dunes themselves but also for protecting inland areas from storm surges and flooding.

While these plants may also have benefits related to wildlife attraction, aesthetic enhancement, and their status as rare species, the most significant and widely recognized reason for their protection is their effectiveness in shoreline stabilization and dune building. This ecological function is essential to maintaining coastal environments, which are often vulnerable to erosion and environmental degradation. Therefore, ensuring the health and presence of sea oats and sea grapes is vital for sustaining coastal ecosystems and protecting property and habitats from erosion-related damage.
