Swan Coastal Plain

An ancient sandy plain formed by the sea in ages past stretches from Jurien to the north of Perth down to Bunbury in the south. The Swan Coastal Plain is made up of deep sandy soils but supports a large number of lakes and swamps. Eight different species of frogs are commonly found in these habitats.
