Barker-Greenfield Wetland





Barker Inlet Wetlands

Barker Inlet Wetlands: Adelaide Coast Region of South Australia


It's an oasis and it's located within ear shot of what's called the Connector Road at Wingfield. Up to forty thousand vehicles use it but it doesn't seem to worry the avocets which trawl the bottom for a good feed.

Before the Barker Inlet Wetlands were constructed a concrete drain used to take stormwater from Gepps Cross and dump it straight into the Port River mangroves.


Now it meanders around the base of the hill, down passed the islands there where you can see the pelicans sitting. Then it snakes its way around the base of the hill on the other side, down around passed the Weather Station and back to the road, out through the culvert and out the other side.

Water is trapped for ten days in a wetland where the reeds, paperbarks, sheoaks and gums have all been specially planted. Pollutants fall to the bottom and soon sunlight can penetrate the gloom killing off pathogens and any other nasties. All of which makes for a frog friendly environment.

The spotted marsh frogs are back in large numbers in a wetland bounded by salt mounds, power stations and industrial parks. But despite all that, Mr Percival and his mates will persevere in this environment if we clean it up.


Watch out for the red necked avocet - It's beak actually curves up. He's dipping sideways. He gets his head down in the mud and you just won't see what he's feeding on.

From avocets to swans and sharp-tailed sandpipers from Siberia and Alaska - more than one hundred and twenty species have been identified in this wetland where fresh and saltwater meet.


This rather innocuous little drain is absolutely vital to the success of this entire wetlands system. In low tide the water level in these mud flats falls away and is ultimately replaced by fresh water from the city side which has been purified and cleaned in the masses of reeds which you see all around here.

It's fresh water that ultimately makes it's way into the nearby mangroves - a major breeding ground for King George Whiting and a haven for dolphins.








The Clues


To the five ways north of Adelaide you must go.
Head to the Port that is no more.
Go over the bridge but don’t go under the bridge.
Head to the port that is a port.
Pull over when you see the powerful pole and the sign that stops cars.
Follow the path that winds about.
Cross a bridge on foot but don’t cross the next one.
In the bushes on the left is the stamp you seek.
