The Sand Dune Study is conducted in a sand dune area which exhibits a succession of vegetation, from Pig Face and Goat’s Foot just above the high tide mark to full size trees, such as Banksias and Casuarinas, beyond the first sand dune. The sand dune plant community consists of various species, each suited to a particular zone in the dune system and each serving certain functions within these zones. The study of the sand dune system involves the identification of plant species along transects from the beach to the second dune. A profile of the dune transect is drawn and factors are noted which influence the species of plants identified. Coloured ID sheets are used to help identify the different species. Some abiotic variables are measured, such as air temperature, soil pH and light intensity, both on the open dune and in the tree zone. Equipment such as light meters, pH meters and thermometers are used by students to measure the abiotic parameters.
