Coastal wetlands are a diminishing resource.
Decades of land reclamation, dumping of contaminated wastes, weed invasion and neglect have destroyed many wetland areas along the more heavily populated sections of the New South Wales coast. Porters Creek wetlands near Wyong, on the New South Wales central coast, provide a large influx of clean water for Tuggerah Lakes and may be impacted by a number of fringe developments that have been proposed. One component of wetland biodiversity that can be measured and assessed is its vertebrate fauna. Each fauna group was surveyed using quantitative and repeatable methods. Ten areas were chosen within the Porters Creek wetland for the fauna study sites.
