The Paisley-Challis Wetlands, formed by the restructure of two urban stormwater drains, are attractive wetlands that filter pollutants from local stormwater and provide valuable bird habitat.
Stormwater flows through a series of ponds, and sediment and pollutants are naturally filtered out by the settling ponds planted with various species of local native reeds. Micro-organisms on the plant stems help to break down many of the pollutants.
"The western shoreline of the Port Phillip Bay contains one of Australia's richest saltmarshes... Its flora is of national significance, while its fauna is of international significance. Here we have some of the best examples of dry saltmarsh... in coastal Victoria".
