Coastal habitats are diverse and vary in the extent to which they are shaped by physiographic processes, such as wave action, wind, tides and sediment availability, and the relative influence of terrestrial and marine environments, e.g. tidal inundation versus groundwater levels. Coastal systems usually comprise mosaics of habitats that are functionally interdependent: for instance, saltmarsh may form behind a barrier island or shingle ridge that itself may also support a dune system; or estuaries may include a range of habitats that ultimately depend on sediment supply from the catchment and the mixing of fresh and saline waters. Coastal grazing marsh is a man-made, largely freshwater habitat, occurring landward of intertidal and coastal habitats and protected from them by natural or man-made structures. Whilst grazing marsh and other coastal habitats are not strictly functionally interdependent, there are significant conflicts between protecting grazing marsh and allowing landward movement of coastal habitats.
