Dead seabirds needed for plastic pollution study
Lauren Roman, a graduate ecology / zoology student from the
University of Queensland is undertaking a study on plastic marine debris in the
diets of Australian seabirds and shorebirds. Lauren’s research for her honours
thesis is being supervised by Dr Kathy Townsend based at the UQ Moreton Bay
Research Station at Dunwich. To conduct
the study in a way that is as ethical as possible and brings no stress or harm
to living birds, the approach being used is to dissect birds that have already
died of natural (or unnatural) causes.
Lauren is seeking assistance from FOSI members with the
collection of suitable specimens. Lauren requests that if we find any dead
marine birds (seabird/ shorebird/ gull/ heron/ egret etc) that are relatively
intact, that we place them in a plastic bag and bring them to the Moreton Bay
Research Station and ask for the specimen to be put in the freezer for her. We
will report back to members on her study’s findings.
A shy creature, distantly related to the elephant, which communicates by chirps, whistles and barks – the dugong may be one of Moreton Bay’s least seen and most fascinating inhabitants. Approximately 1000 dugongs live in the warm waters of the sheltered and shallow bay. Globally, however, there are serious threats to this gentle animal’s survival. The World Conservation Union lists the dugong as vulnerable to extinction.
The name dugong derives from a Malay word meaning Lady of the Sea, yet elsewhere they are less-flatteringly referred to as Sea Cows, due to their diet of seagrass.
They are the only marine herbivorous sea mammals in the world and have been observed to suckle their young for up to five years, even though calves start eating seagrass at three months old.
Solitary animals, they travel alone or in pairs for most of their 70-year lifespan, although they have been seen in herds of 10 to 300.
Their distant relationship to the elephant goes some way to explaining the dugong…
Early this year, with the wild weather, dramatic erosion occurred once again at Amity and Point Lookout. In January a large chunk of the Amity foreshore fell into the Rainbow Channel, causing a worrying time for residents, while at Point Lookout all beaches were left denuded of sand and with a number of the fringing casuarinas undermined and collapsed. Erosion does seem to be gaining in intensity and needs to be taken seriously by the powers that be.
Amity has a long history of drastic erosion with the settlement now 100 metres or so inland from where it was first established. On this occasion it was halted by the dumping of about 300 tonnes of rock along the shores. But there are varying views on the long–term prospects and possible remedies and concern about Council consideration of a “planned strategic retreat” strategy.
The Redland City Council is currently developing a Shoreline Erosion Management Plan for Amity. There is no such plan for the Point but Councillor Craig Ogilvie …
In this edition we have seen the difference 10 years of bush care can make and some weeds to watch out for. Below is some advice as to suitable trees, ground cover and shrubs to plant in your Stradbroke garden. Suitable native trees Lophestemon confertus (box tree) - canopy tree for big
gardens or pruningBanksia integrifolia – (coastal banksia) - attracts
birds Banksia aemula or serrata (wallum banksia) – attracts birdsElaeocarpus reticulatus (blue berry ash)Pandanus pedunculatus (pandanus/ screw palm) Cupaniopsis anacardioides (tuckeroo)
