Patterns of tidal flushing within a mangrove forest: Lake Coombabah, south east Queensland, Australia

TL;DRAbstract

The project sought to discover the pattern of tidal flooding at the mangrove fringe of Lake Coombabah in south east Queensland. The area is urbanising rapidly and pressures on wetlands are increasing. The role of mangrove systems in the larger context was not well understood, for example their contribution to the habitats of other organisms such as fish and crabs. As well, there are negative issues with the wetlands as they provide habitats for disease-bearing mosquitoes. Ross River and Barmah Forest viruses are the major ones in the Lake Coombabah area. The mangroves thus play a dual role: in providing important habitat for wildlife and in providing habitat for mosquitoes. The nature of the flooding pattern, its size and duration, are key elements for the mosquitoes that require a variety of water levels (for the species in this area). The aim was to explore flooding patterns and to see if high tides flooded all mangrove areas adjacent to Lake Coombabah and what kind of water fluctuat
