Working on our saltmarsh rehabilitation project, REF Inc has been working with its partners to control as much weed as possible around the large saltmarsh area at the end of the Silcock Street Reserve. Last week we were working with a team from Conservation Volunteers Australia when I noticed that the Osprey’s nest adjacent to the Redcliffe Golf Club has been diminished. The ospreys themselves were not to be seen anywhere.

This gave us a chance to reflect on their presence in the area. For the past four years they have provided a highlight for many visitors and volunteers to the project area. On a number of community days including bushcare and Green Army events the breeding pair looked down from their roost as if to approve the work being done to enhance the area. At different times we would often catch glimpses of their chicks (three sets from our count) or se one of the adult birds at their feeding tree with a fish caught from the adjacent Hays Inlet.
​
Their nest has disintegrated, although the tree is still strong and clear at the top. According to bird experts, they may well return and rebuild the nest in the near future. Alternatively they may have found a new roosting tree, hopefully nearby. One thing is for certain, we will be keeping our eyes out to see what happens next.  They are an apex predator and have shown us that there are still fish to be caught in Hays Inlet. They are a fantastic bird to watch in the wild, for some a real privilege to see them go about their daily routine. They remind us why we care about the area, so let’s hope they rebuild their nest so we can enjoy their presence each time we visit the reserve.
​

Hays Inlet is well known for its birdlife and in particular waders. Many of the migrating birds have now left Moreton Bay to make their way to their Northern Hemisphere breeding grounds. They will return to our waters in September. In the meantime there are a still a number of residential wading birds including stilts, herons and spoonbills that will spend the autumn and winter months on the intertidal flats of Moreton Bay. One particularly versatile bird, the Pied Oystercatcher can not only be seen in the wetland areas like Hays Inlet but also along the surf beaches of the region including Moreton and Bribie islands as well as the Gold Coast and Sunshine coastlines.

I was fortunate to spend a few days at Noosa over the Easter break and by chance I had my camera on me when a pair of oystercatchers worked the ebbing tide. If you have ever tried to catch pipis, a bivalve mollusc located on the waterline of the surf, you will realise how difficult this task can be. Incredibly oystercatchers are able to work the breaking wave zone and locate and pull pipis out of the sand with regular monotony.

Of course finding pipis is one thing but being able to crack them open is another matter altogether, especially if you are a bird. Again these birds appear to find the task relatively easy. They insert their bill into the hapless bivalve and carry them to the beach, where they insert their beak further into the shell and then using mandibles like a knife they slice through the strong muscle of the mollusc before extracting them completely from their shells. And in no time at all they are feeding on a nutritious piece of protein, thanks to their fishing skills and well-equipped bills.
​
And left on the beach are the two valves of the former pipi! Just minutes ago it was buried in the sand beneath the waves and now the only evidence of its existence is that familiar purple butterfly-like pair of valves.
​

There are other benefits to managing our water resources and some simple things worth doing at our own local:

• Managing and improving the wetlands of Hays Inlet and Deception Bay – by maintaining the mangrove, saltmarsh and buffer regions (melaleuca and casuarina) and allowing runoff to be slowed down, filtered and a decrease in erosion – we can enhance biodiversity, fisheries production as well as provide an effective buffer against storm surges (which are predicted to increase in frequency and sea level over the next century). And saltmarsh and mangrove habitats have the capacity to absorb high levels of carbon.
• Improve general forest areas and wherever possible plant trees in urban areas as well as semi-rural and conservation areas. Forest areas provide shade and can mitigate some heat sink effects associated with urban areas, particularly high density estates. They also provide habitat for wildlife, prevent soil erosion, store carbon and provide aesthetic qualities to the landscape. Recent research has discovered that rainforest trees have the capacity to create rain through an atmospheric seeding process. So it is important that we preserve as much forest as possible within the Moreton Bay Region.
• Finally managing our water use at the domestic level can also make a difference to the water quality of our waterways and Moreton Bay. Manage soil erosion and stormwater by making sure we water our gardens wisely, e.g. wash cars on the lawn rather than on driveways can all have an impact on our stormwater runoff. Ensuring our rubbish is binned appropriately, it’s amazing how much rubbish (especially plastics) ends up in our waterways and Moreton Bay.  Volunteer for projects around landcare and waterways – e.g. making sure our creeks and waterways have the correct vegetation to prevent sediments entering our waterways and impacting on water quality.

 

World Water Day does give many of us a chance to reflect on the way we live our lives and to consider some of the activities we might engage in to improve water quality and access to clean water for all of us.

The daily news and media is full of stories on economic growth, underpinned by population growth that drives the need for higher levels of the development of natural and agricultural land to accommodate housing, industry and infrastructure.
 
At Redcliffe, we live in one of the highest urbanised areas in South east Queensland and these days you have to move to the fringe areas of Hays Inlet and Deception Bay to see any of the original habitat associated with our peninsula. We know in the past, Redcliffe was characterised by wetland habitats including freshwater swamps, Eucalypt forest and patches of remnant coastal rainforest. I was particularly struck by a quote from Constance Campbell Petrie (1904) who reflected on the changes to the area especially in reference to the diminishing forests and the ways of life of the original inhabitants of the land. I include a quote below:
 
If all the old aboriginals of Brisbane could come to life again they would not recognise their country – the country we have stolen from them. If they went hunting in the forests, where would be their spoil? – where, indeed, would they find the forests to hunt in? Oh! How they must have loved those forests, their forests…”God made the country, man made the town.” As the aboriginal hunted careless and free in those days long gone, little dreamed he of what his brother-white would do – little dreamed there was a brother-white.
 
The waters even have changed since those times. Dugong used to be very plentiful then, when there was nothing much in the way of disturbances. The aboriginals would catch them at Fisherman’s Island; at St Helena at a place near Dunwich they called “Gumpi,” at Bribie Passage and the mouth of the Pine River.
 
 (Petrie, C.C 1904, page 66)   
 
If Constance was live today (just over 110 years later) I wonder what she would think of Brisbane and Moreton Bay now.  No doubt it would almost be unrecognisable to her.
 
Even now though, anyone can take a trip to one of the local highlands such as Lamington National Park or the D’Aguilar ranges, or head out to one of the sand islands and marvel at what would have once been a spectacular domain of forests, wetlands and blue waters and of course the amazing wildlife. We should treasure all of these places, the last remaining natural jewels in an urbanised landscape.

Deep River Bend Reserve on the Pine River is a public amenity including a boat ramp, barbecue and picnic areas and fishing platforms. It is adjacent to the Tinchi Tamba wetlands. In the same area there is also a walking track which allows the public to enjoy the variety of habitats and wildlife (particularly the birdlife) associated with this riverine system.

The track includes sections of boardwalk (in tidal areas such as mangroves and saltmarsh) along with clear pathways (made of road base in the higher areas and timber slatting in other areas where occasional flooding can occur such as in the stands of Casuarina).

The pathway is around 1.6 kilometres in distance and includes an extra pathway to a bird hide on the Bald Hills Creek. This structure allows participants to watch the local shorebirds roosting and feeding in the mangrove and tidal flat areas without the wildlife being disturbed. There is also some great examples of interpretive signage to help people understand the environment they are interacting with.

Winter and spring is a great time to check out this amenity and any visitor will be rewarded with the sights and sounds of the birdlife including scarlet honeyeaters, fantails and whistlers, kingfishers and the local wading birds.

The "Island Track" provide some examples of infrastructure that could be used for the Hays Inlet project. The pathway not only provides access for nature lovers, but also helps to keep traffic off the sensitive wetland areas.

What do you think? Is there anything else you feel might add to the design of the Hays Inlet project site? Let us know by posting a comment.

Yesterday the Birders of the South Pine River completed their winter survey of the Eco-project at Silcock Street, Clontarf. This marks 2 years of seasonal surveys and we are now starting to appreciate the value of this site in terms of biodiversity. In the first year, the survey identified 101 different species of birds utilising the site. In the past 12 months a further 13 species have been identified taking the total to 114 species!

The Eucalypt stands were in bloom and there was plenty of activity in the canopy including flocks of Rainbow Lorikeets, Blue-faced Honeyeaters and Scarlet Honeyeaters flitting from tree to tree. In a recent article we discussed the prevalence of honeyeaters in Australia and this site is no different with 11 species identified at the site. With the Melaleuca due to flower next, there will continue to be ample supply of nectar over the next few months. The graph below shows the variation in numbers of bird species seen on a seasonal basis.

Through the surveys we have also learnt that at least 27 species of birds can be found at the site all year round, with many other species arriving as seasonal visitors no doubt aligning with the pulses of blooms across the forested areas and also the increase of insect life in the warmer months. On the tidal flats of Hays Inlet there are large numbers of residential water birds including the Black-winged Stilts (also known as Pied Stilts) and Red-capped plovers along with some international waders that have remained in Moreton Bay including the Bar-tailed Godwit, the Whimbrel and the critically endangered Eastern Curlew. By the time of the next survey in late spring, migratory birds from Asia and Alaska will have arrived in Moreton Bay and the Inlet.

Hays Inlet is a remarkable site and the work carried out by REF volunteers, bush care volunteers, our Green Army team members and staff and contractors at the Moreton Bay Regional Council to improve the habitat is making a valuable contribution to the wildlife found at the edge of Hays Inlet.

After many years of ongoing work at the Silcock Street Park, REF Inc. and the Moreton Bay Regional Council are one step closer to seeing the approval, design and construction of a boardwalk and pathway, which will provide local residents and visitors with the chance to see some of the Hays Inlet’s remaining natural wonders.
 
The walk from Silcock Street will take visitors through Melaleuca forest, stands of Eucalypt and Casuarina as well as the opportunity to see saltmarsh plains, mangrove forests before arriving at a platform allowing them to take in the sights and wildlife of Hays Inlet including a panoramic view of the Great Dividing Range and Glasshouse Mountains.
 
The area teems with birdlife and is home to some of Moreton Bay’s remaining koala population as well as providing roosting sites for international wading birds including the critically endangered Eastern Curlew. The project aims to provide a community asset that raises awareness of the value of our remaining wetlands, not only as a site of significant biodiversity but also for the environmental services it provides such as improved water quality, storm surge protection and a nursery site for commercial and recreational species of fish and crustaceans.
 
The site has also been a community focal point with 3 Green Army projects having conducted significant habitat restoration in the surrounding wetlands and forest areas, 3 community engagement days and the formation of the Hays Inlet Bush Care Group. During the next year we can look forward to a fourth Green Army team working on habitat restoration as well as the design and commencement of the Ecopath.
 
Yesterday, committee members of REF including president, Chris Joyce inspected the site and looked at some of the potential design elements and issues for the pathway and boardwalk. At this time of the year, the weather is perfect to take in some of the sights and sounds of the Reserve. The wildlife and views at the end of the walk underlined what a valuable asset the path and boardwalk will provide for many generations to come.  The immediate challenge will be in the design and incorporating a safe pathway that provides views of the differing habitats and their associated wildlife for the enjoyment of visitors.

Australia is an unusual place in terms of its wildlife and in particular birds. The prevalence of honeyeaters is remarkable. From our urban backyards, parks and reserves to the wetlands, eucalypt and paperbark forests to our mountain and coastal rainforests you will find honeyeaters.

Australia is the land of sugar and nectar. The country’s generally poor and ancient soils lack a number of nutrients suitable for plant growth. Many of our native plants including eucalypts, melaleucas, banksias and grevilleas produce large amounts of excess sugar. These sugars are a product of photosynthesis and due to the lack of soil quality including some amino acids, many plants have diverted these excesses into the production of high amounts of nectar in order to attract and exploit animals as pollinators and seed dispersers.
  
The general absence of arboreal mammals in Australia has provided opportunities for honeyeaters to diversify and take advantage of this bounty and there are over 75 species in Australia. They range from the large and noisy friar and wattlebirds, the small and busy brown honeyeaters to the mob forming minor birds.

You can see many of these honeyeaters taking advantage of our backyards especially where people have planted “bird-attracting” gardens. If you take a look at the remaining forests of paperbark and eucalypt around Moreton Bay you will also see many different types of honeyeaters along with lorikeets feeding on the seasonal waves of flowers. They also take advantage of the insects associated with these plants and in particular psyllids which produce honeydew shelters on the underside of leaves known as lerps. Late winter and early spring provides an opportunity to see other species of honeyeater including the scarlet honeyeater.

I live in an urbanised area and was surprised to see a small tribe of Fairy Wrens visit my backyard. I have a few banksias, bottlebrushes and grevilleas in our gardens as they are hardy and attract wildlife to the area. The wrens however were interested in the insects associated with our area. This blog is dedicated to providing information about the value of our wetlands, the wildlife and the people who work to preserve our natural heritage.

The Redcliffe peninsula is one of the most urbanised areas in Australia with very little land put aside for parks and wildlife. It’s understandable as the peninsula juts out into Moreton Bay and has some amazing beach areas so it’s a great place to live. Cool sea breezes and its close proximity to Brisbane add to the attraction. But it’s amazing what creatures can turn up in your yard if you provide some habitat for them.
  
So if you have a little space, plant some native vegetation. Consider a small frog pond, or provide safe access to water (so domestic cats can’t intervene).  Then just sit back and wait for them to come; you will be rewarded with a wide range of local wildlife interacting with your garden.
