Mutton Cove Conservation Park. Site of historic ship wrecks, birds and industrial development. Severely degraded by since European Settlement is now in need of extensive restoration.
When I’m back home in Adelaide I don’t get much time to go bird watching. There is alway more jobs lined up than you can shake a big stick at. So, when a small window appears and I can escape for a few hours I head north up the beach from my home, past historic Port Adelaide and up the Le Fevre Peninsular to Mutton Park Conservation Reserve. Its a great place to go bird watching... close to the centre of Adelaide, not too big, no crowds, not even anybody... a reasonable number of birds... what more could you want? Well when it comes to Mutton Cove, lots...

The Le Fevre Peninsular stretches north from Port Adelaide, bounded on the west by the Gulf St Vincent and to the north and east by the Port River. It’s a low lying finger of land much used for large scale industrial purposes, a process that grows even bigger today with the expansion of port facilities at Outer Harbour and the massive development of the Techport Australia project to build air warfare destroyers and potentially new submarines. All of this is fine, if Australia wants to develop more industry, it has to put it somewhere.
Mutton Cove has the last remaining samphire on the Le Fevre Peninsular. Brown Songlark sighted here in January 2012 was the first of this species seen here over my visits of the last few years.
Tucked away in one small out of the way corner of the peninsular is Mutton Cove, the last remaining samphire flats and mangrove woodland on the peninsular. It’s a small piece of natural estuarine landscape, albeit severely degraded since european settlement, in an otherwise industrial landscape. It probably owes it’s existence more to being abandoned as useless rather than because of the farsightedness of some sagacious person. Over the years it’s been a dumping ground for rubbish, old cars, waste and all manner of degradation. Fortunately it was rescued before it was totally reclaimed and is now a conservation reserve. However today, it still appears to be a wasteland despite the efforts of community groups and volunteers who have laboured long and hard to remove rubbish, plant shrubs and improve facilities.
Contaminated area suffering from past unregulated dumping and reduced tidal flows and tide heights with which to flush the Cove properly.
The Cove was once part of the Port River tidal inlet and as such its estuarine habitat was subject to the natural tides of the river. Some time ago the whole area was largely isolated from the main tidal flow by the construction of a sea wall. Since then a limited flow of sea water into the Cove occurs through some inadequate piping that allows sea water to flow in during flood tides and drain out on the ebb.
The sea wall which separates the Port River and the Cove. The pipes just visible under water only allow a portion of the incoming tide to flow in restricting tidal range and flushing. This wall needs to be breached with a bridge that allows full tidal flow.
As you would expect, the sea level in the Port River rises for several hours during the flood tide, covering the intertidal zone until it reaches its high tide. However within Mutton Cove, because the pipes restrict the flow, by the time the river tide is at its peak the Cove level is still much lower, by a half metre or more. When the river tide falls, initially the tide continues to flow in for a short time until the the river level and the Cove level are the same and then outflow begins, again lagging behind the river tide.
Waders frequent the Cover. These Red-necked Stint are resting on the river side of the sea wall.
There are two major effects of the restricted flow into the Cove. First the intertidal zone has less depth because the full extent of the tidal change is never achieved and secondly there isn’t sufficient flow in and out to flush the Cove properly. This means that the distribution zones of the intertidal plants species is different to the natural surrounding inter-tidal area and the reduced flow causes algal blooms lie in decomposing beds alongside the waterways, altered salinity and high contaminant levels.

To add to this the whole reserve is unsightly; weeds abound, piles of rubble from past dumping still are much evident; the pathways, fences are in poor repair and scattered blocks of concrete, tyres and other rubbish are scattered about. Oozing contaminants seep into the samphire from the industrial waste that was dumped there in the past. Many of the plants that volunteers laboriously planted to improve the Cove have died through lack of care. All in all, it’s sad to say is what you often expect to see at an out of sight - out of mind nature reserve.
Beside Mutton Cove new buildings as part of the $10 Billion Techport Naval Hub are extensively landscaped and maintained.
All around the Cove there is evidence of the ten billion dollars that is being spent on the Techport development which has been labelled as Australia’s premier naval industry hub. Among all the huge development of buildings and shipping facilities the developers have done extensive landscaping and planting of native flora. It’s a different world on the other side of the fence in the Cove which by comparison languishes as an unwanted and unsightly backwater. It’s like a sore thumb!
The Australian Submarine Corporation and the new airwarfare destroyers are neighbours. Even though Mutton Cove is surrounded by industrial development it's value as a nature reserve should not be discounted. Many plant and bird species exist within the reserve.
According to the spin, the opening of the Techport was attended by the US Ambassador and the Deputy Secretary of Defence and delegations from Spain, India, Germany and Israel have already visited Techport... I hope they kept the visitors away from seeing Mutton Cove.

Some of those ten billion dollars needs to be spent on restoring Mutton Cove to its natural state and improving the facilities to confirm with locals and visitors alike that we here in Adelaide care as much for our natural environment as we do for industrial development.
So, what more could you want for Mutton Cove? For starters the sea wall needs to be breached so that the natural tidal range can be re-established. The majority of the sea wall should remain because it provides a good walkway, but it needs a buttressed bridge under which the tide can flow unimpeded. The facilities in the Cove need to be brought up and maintained to the same standard as the Techport infrastructure surrounding the park with proper pathways, fences, hides for viewing bird foraging areas and rest facilities for visitors.

It is well past the time in which industrial and government stakeholders of Techport need to take the leadership and responsibility for what is an important conservation reserve in their back yard. After all this should be a premier nature reserve reflecting its surroundings, not an embarrasment!

Anyway, anyway, anyway...back to those jobs... well they say you’ll never empty your in-tray, the to-do list just gets bugger (freudian slip)... so my goal when they ultimately cart me away in a box to the knackers yard... the in-tray and the to-do list will still be overloaded but my bird list will hopefully be looking better than today... well that’s the plan. Dreams are free!
And a final thought... a name change would be good. Mutton is not exactly an inspiring name although it's appropriate in its current state. Given its aboriginal heritage I'm sure a more appropriate name could be found.
