Yanga National Park has significant ecological values, including having some of the largest populations of vulnerable Southern Bell frogs, and is an important drought refuge for many aquatic and water-dependent species.
Mercedes Swamp is located near Redbank Weir which is upstream of Balranald. Mercedes Swamp supports River Red Gum stands and wetland habitat, and is known to provide breeding opportunities for the Southern Bell Frog (listed as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

The wetland is a natural corridor for floodwater to enter the River Red Gum forest located within Yanga National Park and is dominated by extensive beds of Tall Spike Rush and Common Reed.
The Commonwealth is providing 1,904 ML to Mercedes Swamp and Twin Bridges Wetland at Yanga National Park. In addition, the NSW Government will provide 1,500 ML.
