Chapter 4 discusses restoration of the natural functions of degraded landforms and landforms that provide a limited number of shore protection or recreational values. The case is made to make beach/dune systems more dynamic to allow nature to undergo exchanges of sediment, nutrients, and biota; follow cycles of accretion, erosion, growth, and decay; and retain diversity, complexity, and the ability to deliver ecosystem services. Actions include reestablishing physical habitat characteristics (e.g., overwash areas and slacks), removing invasive species, and reinitiating cycles of growth and decay by reducing vegetation cover or destabilizing surfaces to favor reworking by waves and winds. Many of these actions are most appropriate for landscapes that are usually found within natural preserves and consistent with the regulations governing their management. Issues associated with removing wrack (beach cast), driving on the beach, restoring mined sites, and stabilizing dune fields that are overly mobile are also addressed in this chapter. Restoration actions in intensively developed areas where beach and dune evolution are under severe spatial constraints are addressed in subsequent chapters.
