Oatley Bay Tree Massacre

A tree massacre has been bought to our attention at the Oatley Bay Memorial Boardwalk. A nearby resident was seen removing gum trees, mangrove trees casuarinas and others on the 13th of July.

Council were notified and  on the day visited the site and confiscated a saw and ladder.  Clearing continued on  27th July and 1st August,  this was reported with photos to council.

OFF members have visited this site and seen lots of small trees and some mangrove branches cut down and the stumps pasted in black (?poison).  All the destroyed vegetation still lying on the ground. It has certainly created a ‘water view’ for the occupant of one unit in the Kingfisher block (No. 136 Morshead Drive). 

Some have noted it would seem an ideal place to erect one of those boards that blocks the view from the unit and shames the perpetrator.  It has damaged the ambience of the Memorial Boardwalk; following website says “construction was competed in October 2008 and boardwalk was officially launched by the mayor and representatives from the St George RS.  http://www.kogarah.nsw.gov.au/environment/local-projects/foreshore

Three Yellow-tailed Black Cockatoos were seen climbing amongst the casuarinas that were still standing, and a Magpie-Lark was foraging on the exposed mud flat – certainly an area of significance for birds.

 

 

 

Centennial Park meander in the labyrinth & swamplands

On Friday 30th June 16 members of OFF took the train and bus to Centennial Park on a crisp, clear morning.
 
After morning coffee (with good use of Keep It Cups) and singing Happy Birthday to one of our group we set off for a gentle walk to the Lachlan Swamp.
 
 
 
 
Lachlan Swamp  is a magnificent paperbark swamp and home to a Flying Fox colony. We also observed a large flock of Little Corellas  and amongst them we spotted a few Long-billed Corellas. The Long-billed are normally found in Southern New South Wales.
 
 
 
From there we proceeded to the Labyrinth where many of us followed the path into its centre and out again. This sandstone labyrinth was completed in August 2014 having taken 5 months to build. It was based on the one in Chartres Cathedral in France.
 
 
 
After a picnic lunch on the lawns in the sun we walked back to Oxford St and caught a bus to the Reservoir Park in Paddington. This park is a re-purposing of the old water reservoir – a small gem easily overlooked. It also has a lovely example of a Wollemi Pine tree.
This completed our walk. We were very fortunate to have had such a sunny winter’s day as the forecast in the beginning of the week had been very different.

Heathcote National Park to Waterfall

After heavy overnight rain and with a forecast of scattered showers for at least the morning period, 8 intrepid walkers departed Oatley Station during rain showers and arrived at Heathcote in clearing conditions. There we met with 3 more souls who joined us for coffee and the reading of the “riot act” during which the rain returned. In spite of the conditions (both “riot” and weather) 11 starters headed off through the Scouts and Guides training camp, towards the bottom of the Heathcote Valley and the Woronora pipeline track.

By the time we reached our first creek crossing (Battery Causeway) the rain had passed making morning tea opportune. Water levels had subsided from those of the reccy walk 2 weeks earlier making all the creek crossings relatively easy, (mostly) without even getting wet feet.

The Bullawarring Track from there to Waterfall led us past some spectacularly gnarled angophoras, verdant grass trees, geebungs and banksias as well as waterfalls and plenty of rock pools and a swimming hole. Whilst enjoying a lunch break in the now pleasant sunshine ‘near ‘the mysterious Myuna Pool and watching a beautiful Kingfisher flit about, Sharyn and Phil joined us having walked from the Waterfall end of the track.

 

 

 

To finish the 10km walk, at the top of Heathcote Creek, we climbed up quite a steep (140m ascent) ridge and then on to the Waterfall train station. A tired group, but I think satisfied with the day’s challenges and rewards, made their way home, some via a stop at the Oatley pub for welcome refreshments.

Cruising the Scenic Port Hacking River

dscn1561-2-groupThe last OFF outing for the year was a three-hour return cruise on Wednesday 30 November from Gunnamatta Bay at Cronulla, along the Hacking River to Royal National Park. Thirty-six members and friends embarked at 10.30 am on a fine mild day and enjoyed a smooth and comfortable ride (mid-week there was very little water traffic). Unlimited morning tea was available throughout the cruise and at the conclusion of the trip some of us lunched in Cronulla. It was unfortunate that Maureen, who had recommended the cruise for our 2016 program, was unable to join us on the day.

We travelled on the M.V. Tom Thumb III, named after the 2.5 metre rowing boat in which Bass and Flinders and ‘the boy Martin’ explored the area in 1796. Their voyage is also commemorated by a monument at Bass and Flinders Point in Cronulla but over the intervening 220 years much of the landscape they saw has been drastically altered.

 

p1010150On the southern side of Port Hacking, after we passed the settlements of Bundeena and Maianbar that border the Royal National Park, it was not difficult to envisage what the first Tom Thumb’s crew would have seen. The shores remain covered in typical Sydney sandstone flora dominated by flowering angophoras with their summertime deep orange trunks and an understorey of native shrubs and grass trees. Silver Gulls, Crested Terns, Pied Cormorants and a solitary Pied Oystercatcher were resting on a sandbar, and we were surprised and delighted to see a dolphin in the river. Graham spotted an adult and an immature White-bellied Sea Eagle.

p1010155The tide was high so our boat could motor as far as the weir at Audley; some passengers recalled Sunday School outings there. A kayaker was fishing in the shallows and picnickers on the bank waved to us. The commentator on board said it was planned, in the event of a Japanese landing during World War II, to bring all navigable craft in Port Hacking up the river to this point and burn them.

dscn1540-middenThe commentator also spoke about the original inhabitants – the Tharawal or Dharwal people, their place names and culture; some of their middens were destroyed when shells were gathered as a source of lime for buildings in Sydney. There were anecdotes about the European settlers and early industries including a fish hatchery and deer-farming. Many landmarks and significant dwellings and boathouses were pointed out, and free maps on board allowed us to trace our route. Also on board were albums of early photos and newspaper cuttings relating to life on Port Hacking.

 

p1010171

The return journey took us into some of the bays on the northern shores of Port Hacking, a completely different landscape featuring palatial homes, private jetties and big boats. But there were also some swimming baths for the general public and one passenger said she had spent her youthful summers there.

p1010136Shiprock Aquatic Reserve at the entrance to Burraneer Bay was pointed out. The biodiversity in this 2 hectare reserve so close to Cronulla is extraordinary and was illustrated by Gary Dunnet at an OFF meeting in February 2010. He explained the adaptations that allowed animals and algae to crowd onto the sandy substrates and rocky cliffs of what is essentially a flooded sandstone valley, and he listed some of the land and water-based human activities that can threaten that biodiversity. It was ironic that our tour guide also pointed out the former Fisheries Research Centre at the entrance to Gunnamatta Bay; scientists at the Centre which was closed down by the NSW Government in 2011, would doubtless have contributed to knowledge of Shiprock’s rich biodiversity.

An Expedition to Spitzbergen in the Arctic

magdalena-fijordGary Schoer, OFF member and extensive Polar traveller joined us once again in November to share his photos and assessment of the beauties of and threats to the Arctic. Gary took us with him on a Aurora Expedition small group expedition to the Svalbard Archipaelego which includes its biggest Island, Spitzbergen, in between Northern Norway and Greenland. 

 
puffinsWhile Gary was fortunate to see and capture some great images of seabirds such as puffins, Northern Fulmars, Ivory Gulls and Guillemonts to name a few, he gave additional insights into their conservation status and particular threats which are causing many populations to plummet in the last 20 years or so.
 
calving-arcticThe smoking gun seems to be especially the rapid increase in average air temperatures, reduction in amount of sea ice especially thicker multi-year ice. In some areas average temperatures have increased by as much as 10 degrees celsius, causing the frozen soil of the tundra to melt and even creating additional pine forests where once there were no trees over many parts of the Arctic. 
 
IMG_9926bear


 
Gary had to travel to 81 degrees North to see 6 of 7 polar bears sighted on the journey on sea ice, which was virtually absent further south…a big change over as little as 15 years since OFFS members Julian and Annette Sheen were there. One other bear was sighted on a small glacial moraine island where it may have had to swim quite a distance to get access to Arctic tern eggs…a pressure on a bird that has flown 15 000 km from Antarctica to breed there.    
 
flowersSo, as Gary emphasised, everything is connected. The changesd size of populations and average body length of the important bird-food fish  may be contributing to sea bird losses.
 
While we in Australia and more temperate worlds argue about how to effect behavioural and fuel use changes to keep average world temperatures below 2 degrees above recent historical levels, the animals, plants and indigenous people who live there are well past that target, and we can only hope that sensible and strong political efforts will stope what we are seeing in the Arctic creating a tipping point that will affect ecosystems well beyond the poles.

St George Community Award to Chris Lloyd

entryChris Lloyd has been a member of Oatley Flora and Fauna Conservation Society since 2007 (and was a family member in the 1960s, when his mother was secretary of the organisation). He has had a life-long concern for the health of the environment and has contributed to a number of programs to monitor and improve wildlife welfare.

award2Since 2013 Chris has co-ordinated the Georges River component of Birdlife Australia’s project on Powerful Owls. Chris has worked with 150 volunteers to monitor 20 or so pairs of Australia’s largest owl as they hunt and breed along the river from Campbelltown to Taren Point. He sees one of the most significant aspects of the project is providing ‘citizen scientists’ with the skills and knowledge to work alongside biologists and contribute to valuable research. Chris has organised numerous workshops for volunteers to learn skills including microscopy and data recording and the application of biological concepts to fieldwork.

powerful-owl-084-webIn the Powerful Owl project Chris has worked closely with Bushcare volunteers. He himself has also undertaken habitat restoration in a separate project – monitoring endangered seabirds and restoring their breeding grounds on islands on the NSW coast. It is tiring and uncomfortable work – at night counting incoming birds, and by day tearing out tangling kikuyu grass and planting native Lomandra as cover for the nesting birds.

Chris has a gift for imparting information on these environmental projects to a general audience. He is an entertaining and persuasive speaker who has addressed groups ranging from small garden clubs along the Georges River to OFF meetings, Bushcare seminars, and service groups including the Men’s Shed of Mortdale. With plans provided by Chris, and encouragement from OFF member and Bushcare staffer Heather Stolle, Mens’ Shed workers have produced a number of nest boxes for birds, enhancing our local habitat for native species.

award4An environmental issue of great concern to OFF is water quality in Georges River and its catchment. Chris is one of our members who has participated for many years in Clean Up Australia Day, removing rubbish that would otherwise pollute our waterways. In recent years he has been joined in that important community work by his partner Nadia and their teenagers.

Bird on the Brink – Regent Honeyeater

P1000348Oatley Flora and Fauna Conservation Society (OFF) volunteers have been helping ANU PhD candidate Ross Crates with his research into the ecology of the Regent Honeyeater, one of the most endangered birds in the country.Capertee NP Regent HE  12-18_10_2015 174There may be as few as 600 individuals remaining in the wild. 

25 Flora and Fauna Society members and friends helped to make 80 Regent Honeyeater and Friar Bird nests over a two week period in August. Ross will use these artificial nests (with false eggs) in Capertee National Park to ascertain which birds and mammals predate on the Regent Honeyeater eggs and young. The nests are now in place with cameras to track predators.

P1000286Ross’s research is aiming to identify the major threats to the survival of the Regent Honeyeater in its woodland habitats. Reducing threats such as nest predation and loss of woodland habitat can contribute to the Regent Honeyeater’s long term survival in the wild.

 This work follows on from his fieldwork into their habitat when he used motion sensor cameras, including one donated by Oatley Flora and Fauna Conservation Society. Ross will present his findings at one of OFF’s regular monthly talks in 2017.

Hike It Baby in Oatley Park

P1000298Sunday 7th August Oatley Fauna and Flora held its first walk with the group Hike It Baby. Five OFF members and 13 adults and 13 children and babies met in Oatley Park to undertake a family friendly exploration of the bushland.

P1000296As we set off to the bushtrack through the centre of the park, we were met by several sulphur crested cockatoos who put on quite a close-up display in the steamroller park.

P1000310We spotted wattles in flower, blueberries on the bluberry ash trees,banksia flowers and seed pods, hardenbergia and  lomandras. Lower down colourful mushrooms, moss and lichens were seen. Scratchmarks on a tree, most likely from a possum, were pointed out.

P1000291The highlight for both children and adults were the two tawny frogmouths roosting in the trees facing Lime Kiln Bay.

We had a very pleasant morning stroll before returning to the steamroller park for morning tea and play.

Yellow Tail Black Cockatoo Research

P1000148 Citizen scientists are being asked to help in a joint project between University of New South Wales, Botanic Gardens & Centennial Parklands.

In recent years there have been significant decline in the populations of Yellow Tailed Black Cockatoos. Birds have been seen in urban areas feeding on introduced pines and food sources in bush parks and golf courses.

Clean-up Australia Day 2016

On Sunday 6th March, 40 people registered at Jinna Reserve South Peakhurst for the OFF Clean-up activity. Numbers from the Society were boosted by a contingent from Mortdale Girl Guides and their parents, plus some individuals who had seen our notices around the suburb.IMG_3194

Some OFF members took their canoes out onto Lime Kiln Bay to get access to what was lurking in
the mangroves, the rest picked their way around the muddy foreshores of the bay on both the
Peakhurst and Oatley Park side of the inlet.

IMG_3181 image2

IMG_3173Total rubbish collected was 36 bags, nearly half of it plastic bottles; also 9 car tyres, PVC piping and metal objects. This was an outstanding result,although real success should be measures by the absence of any rubbish in our bushland and waterways. We thank all those who gave up their morning to contribute to this community event.
