How dunes made?
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.

The first National Park, Sigatoka National Park opened in July, 1989. It has area of about 650 hectares. The dunes has a massive diversity of endemic and exotic (introduced) plant species. It is around 3 km away from the Sigatoka town. The sand in the dunes is deposited in the north west direction because of the South East trade winds blowing the sand inland. The dune has grassland, woodland, savannah vegetation which has many types of species. The area was formed by the fluvial processes while the sand goes under the eroding process either by wind (aeolian), water/ rainfall, humans. It is the largest archiological site in the Pacific and is being protected. The dunes is also protected from the invasive plants and these plants come from the rubbish dump nearby. The vegetation type in the dunes have been severely affected by the fire, cutting, grazing and clearing forests for wood. Ravinal Prakash. BAGCED in LL and GE in USP, SUVA.
