It is envisaged that this project will provide important connectivity between these sites as well as shallow water foraging areas for wetland dependent bird species. The Value of Wetlands Wetlands are often referred to as the ‘kidneys’ of a catchment as they act to filter contaminants out of water systems. This is achieved by slowing water flows which allows for sediments to drop out of Australian Painted Snipe - Male suspension, as well as to facilitate Local Government Taking Action to Protect Ecosystems The Central Tablelands Local Land issues.
