Barrier islands. A barrier island is a long, thin, sandy stretch of land, oriented parallel to the mainland coast that protects the coast from the full force of powerful storm waves. Between the barrier island and the mainland is a calm, protected water body such as a lagoon or bay. Barrier islands are dynamic systems, constantly on the move, migrating under the influence of changing sea levels, storms, waves, tides , and longshore currents.
4.0 Human Impacts on Coastal Sand Dune Ecosystems. As mentioned in the previous chapter, humans have been responsible for changing the lithosphere and biosphere on Coastal Sand Dunes. The Stockton Bight Coastal Sand Dunes are no exception and humans have had both positive and negative impacts upon them. 1. Positive Impacts a) Aboriginals, fire and the Encouragement of Biodiversity. The most positive human impact that has been made on the Stockton Bight Coastal Sand Dunes was by the Aboriginal people, particularly the Worimi Nation. The Worimipeople, through a practice called fire stick farming, have actively encouraged vegetation growth. As explained earlier, vegetation plays two important roles on Coastal Sand Dunes. Firstly, it helps stabilise dunes by trapping and stabilising the sand particles.
