Beach rocks are important because they help prevent coastal erosion, stabilize shorelines, and support habitats for plants and animals. They provide shelter for small organisms such as crabs, mollusks, and insects, and act as surfaces for algae, lichens, and other vegetation, contributing to ecosystem diversity. Their size, shape, and movement reveal patterns of sediment transport, wave action, and past environmental changes, making them useful for geological studies. Beach rocks are also used in habitat restoration and living shoreline projects, where they provide structure for reestablishing plant growth and rebuilding dunes following natural disasters such as hurricanes or disturbances from human development. By combining physical protection with ecological support, they play a critical role in maintaining healthy and resilient shorelines.
