Barker Inlet and Greenfields Wetlands ….a road trip
Dear Reader:
As I cruise along the highway between Port Adelaide and Salisbury a succession of lagoons, ponds and wetlands flash past my windscreen. Over the last couple of decades this once industrial wasteland has become a haven for wildlife and an integral part of the system converting run off into clean water that flows back into the ocean.
Torrens island power station looms behind the wetlands
There are several parking bays along the way that provide vantage points and access to walking paths into the wetlands. In rather an anomalous environmental scene the first one that I explore has the Torrens Island Power Station as a backdrop. And, a family of maned ducks are sheltering amongst the reeds in the foreground.

I drive another couple of kilometres to a large siding where two 4WD vehicles with council logos on them are parked by a path into the wetlands. A small group of volunteers are working on clearing weeds, counting bird species and making other environmental observations about the health of the ecosystem.
Those who care
Leaving the voluntary workers to their work I find the next promising entrance and park my car. A sign indicates that we have moved into the Greenfields Wetlands. The track leads to an old bridge then follows an embankment along the edge of a small lake. The twittering of wrens provides a constant sound track as I scan for water fowl and reptiles along the edge of the reeds. There are coots, swamp hens and Pacific black ducks as well as turtles and water skinks along this section of wetland but it is a glorious little blue wren draws the attention of my long lens.

The watercourse ends in a sluice gate that regulates water flow between the ponds and on one side I can see the swirl and splash of large fish feeding in the shallows. They are carp, an unwelcome guest in any ecosystem and their eradication is probably another task for the council and other environmental protection agencies that watch over these important resources.
Carp feeding in the shallows
My final stop, just before the salt pans is particularly fruitful as there is a mixed population of black swans, herons and spoonbills feeding in a shallow lagoon. It is always interesting to observe these quite diverse species with their individual feeding styles and uniquely evolved body parts. Their beaks, legs and feet have developed unique characteristics over time for feeding in the same area but utilising different food sources and therefore not competing.
A mixed group of waterbirds
And, as is so often the case, my thoughts also turn to food. The Watershed Cafe, just over the bridge, is opportunely positioned on another part of the Greenfields system near Mawson Lakes. Sitting on the edge of a reed fringed lake it is the perfect place for coffee and cake at the end of my wetlands drive.
