Homebush Bay - Human Impacts
- bund walls were built during the 1950s. These changed the flow of water and reduced water levels in the soils. As a result levels of acid sulphate in soils increased.
- Powell's Creek straightened. This directed a lot of run off away from the mangroves, reduced natural deposition of silt, and interfered with natural processes. It increased the speed of runoff resulted in less silt deposited on mangroves and more on the mudflats.
- Urban and industrial land uses increased turbidity, reduced dissolved oxygen in the water.
- Oil spills from vessels using Parramatta River and Sydney Harbour.
- increased phosphates from stormwater
- reduced size of wetlands
- fragmentation of wetlands
- weed invasion
- litter
- trampling
- feral animals
-reclamation of land for agricultural, industrial and residential land use.
