Natural living shorelines are typically used in lower energy environments. They include native vegetation (e.g., marsh grasses and seagrass), clean sediment and biodegradable organic materials (e.g., logs made from coconut fiber). Hybrid living shorelines are typically used in lower to moderate energy environments.
