Coastal sand dunes provide an excellent environment for the study of primary succession. The vegetated dunes within the system have developed on a substrate of unconsolidated sand. This sand has been picked up by the wind from the wide sandy foreshore at low tide and deposited at the top of the beach around any obstacle which interrupts the flow of the wind and reduces its energy - it may be tidal litter on the strand line or a plant.

Desert dunes typically form in arid regions and are characterized by their sandy composition and unique shapes sculpted by wind. Beach dunes, on the other hand, are found along coastlines and are made up of sand deposits from the beach. Both types of dunes play important roles in stabilizing ecosystems and protecting land from erosion.
