‘Briny’ the young, male koala rescued by a Wapengo oyster farm last week was yesterday released back into the wild.
Chris Allen, Threatened Species Officer at the Office of Environment and Heritage (OEH) said the koala had made a good recovery in care at Potoroo Palace and yesterday clambered up a tree on a property north of Tathra.
“Briny, named by locals in recognition of his saltwater experience and after one of the people who rescued him, threw a few longing glances over his shoulder before scurrying high up into the tree,” Mr Allen said.
“He has recovered well from his ordeal last week where he was found clinging to an oyster bag in Wapengo Lake.
“When rescued he was found to be dehydrated but otherwise in a pretty good state of health considering his ordeal.
“This is only the second time a koala has come into care in the region in the past 20 years as the population is so small and widely scattered.
“That the local community could rally so quickly in so many ways to save the life of this animal is a testament to its commitment to support the recovery of these koalas,” Mr Allen said.
The successful rescue, recovery, and release of this animal is very much thanks to Wapengo Lake oyster farmers Brain and Carol Orr, who pulled Briny from the water into their boat, wrapped him up until he stopped shivering and took him to the Bega Veterinary Hospital.
Vets and the carers at Potoroo Palace Wildlife Sanctuary were exceptional in the way they provided quick treatment and closely cared for Briny through his recovery.
Mr Allen also said, “Thanks goes to the locally based koala surveyor Mark Lems who enabled the selection of an appropriate release site in koala habitat close to the rescue site and near other koalas.
“And the local landholders who have welcomed Briny onto their property that is managed under a voluntary conservation agreement.”
Work to better understand and protect the remaining koalas on the NSW Far South Coast continues.
Small, fragile, and very precious communities of koalas scattered in the forests between Bermagui and Tathra are not only opening doors to their own survival but also the survival of their cousins around our continent.
While koalas have been making the news lately it doesn’t mean the population is growing. Numbers are still small, in his 7o odd years, Chris says he has only seen five or six.
Our growing knowledge…
The fact that we know about these koalas and that management practices and response protocols are in place is a testament to a community-based effort that has a sense of magic about it.
Part of the initial drive to investigate this population came from forestry workers and local residents.
Since 2007 people from a range of agencies and backgrounds have literally been on their hands and knees on the forest floor looking for koala evidence – scats (droppings) mainly.
“I get terribly excited about finding koala poo,” Chris laughs.
That work has triggered higher level scientific research that is shaping future koala management in South East New South Wales and beyond.
“Since the 1960’s koala numbers in these coastal forests have been shrinking, and shrinking from the north,” Chris says.
“There were koalas north of the Bermagui – Cobargo Road, in Wallaga Lake National Park and Naira Creek, and on the northern side of Bermagui River, and gradually those numbers declined.”
Research has suggested that the decline has continued southwards – until you hit the Murrah River. South of the river that ‘hands and knees’ bush survey work points to a population that is at least stable and has been so over the last decade.
Sydney University has added its weight to the investigation looking into the secrets of this southern population.
“The way that’s done is that any time we find fresh koala poo we send it off to Sydney Uni and they are able to extract DNA,” Chris explains.
Genetic mapping is a part of the information recorded but so too is a snapshot of disease.
“What has come out of that research is that to the north of the Murrah River animals are carrying chlamydia but to the south – they’re not,” Chris says.
Explaining how and why that is the case remains unresolved, the results of this work are very preliminary.
“The koala is described as a chlamydia rich organism, the population is often carrying several different strains,” Chris says.
“Clearly some populations have a higher level of resilience.”
Chris believes the isolation of this southern population might be a factor in its survival which makes the management of their landscape more critical.
“We’ve picked up evidence of four perhaps five females breeding, we know where their home range areas are, ” Chris says.
Wildfire and climate change the big threats…
Habitat destruction has been one of the issues facing koalas across Australia, these particular Bega Valley marsupials received some respite from the NSW Government in March 2016 when the forests they were living in were protected from further logging with the creation of the Murrah Flora Reserves – taking in what was the Murrah, Tanja, and Mumbulla State Forests, and the southern section of the Bermagui State Forest.
“Almost certainly the greatest threat this population faces now is a major wildfire,” Chris says.
“We’ve been through a research project with the University of Melbourne where they’ve run what’s called fire simulation modeling,” Chris says.
The results highlight the likely progression of fire through this landscape, pinpointing areas for fuel reduction work. In turn, the threat to koalas as well as human life and property is reduced and the capacity of an effective response in the event of a wildfire is improved.
“Koalas can be very good neighbours,” Chris laughs.
The board managing the Biamanga National Park, which is made up of traditional owners, are keen to take on that key role of reducing the fire risk.
“For many years they have wanted to introduce a cultural burning program and I strongly support this,” Chris says.
“The way they see it is on two levels, one is to make an ecological contribution and [two] to provide opportunities for Aboriginal people to be working back on country.
“Within it [cultural burning] is the idea of small, low-intensity, patch burns, small terms just working over a long period of time,” Chris says.
Aside from fire, climate change is the other looming threat to these precious creatures – it’s change that is literally turning the koala’s stomach.
“It’s fairly clear that increased carbon dioxide levels are actually reducing the palatability of eucalypt foliage,” Chris says.
The fear is that the pressure of climate change on local forests will cut the number of suitable feed trees available.
“These koalas are widely scattered because there are only relativity few trees providing adequate nutrition,” Chris believes.
Increasing the number of suitable species like Woollybuott is another ‘rod in the fire’ of this conservation project.
“Woollybuot is really struggling to regenerate,” Chris says.
Thirty small research plots have been established throughout koala country where a range of bush regeneration techniques are being trialled – one of them is the use of seed balls.
“Seed balls are made up of the seed of the target species, clay is mixed with peat mulch and Cayenne pepper,” Chris smiles.
“The Cayenne pepper is the magic ingredient that stops ants and other critters eating the seed.”
A solid clay ball is the result which sits in the bush waiting for good rain.
“Now it’s a question of monitoring and seeing what is most effective in encouraging the regeneration of Woollybuot and other preferred browse species,” Chris says.
Using this research in conjunction with cultural burning; regenerating burnt areas is the long game.
This relatively small forest holds big potential, not just for the survival of the koala according to Chris but so many other species.
“If we can’t hang on to our koala populations we are in big trouble,” Chris says.
“This population is a real litmus test as to what we can do about koala conservation nationally, this is a nationally significant effort.
“This is not just about koalas, the conservation initiatives that flow around the management of koala populations are conserving a whole lot more,” he says.
The success of this work so far has been the amount of knowledge collected and cooperation around better and more careful management of these forests.
It’s understood that the NSW Government will release its NSW Koala Strategy before the end of November.
A whole-of-government approach Environment Minister Gabrielle Upton hopes will stabilise and start to increase koala numbers around the state.
The work of Chris Allen and dozens of other locals have contributed to that process – advice that gives the koala a fighting chance.
While the survival of the koala is the main game, this locally based 10-year project has already had a big win. Its magic has seen a coming together of community will, good science, and politics.
“This is a population on the brink, it’s the last one we’ve got here in the coastal forests of the Bega Valley, let’s do what we can, we owe it to them given their history,” Chris says.
Long before Donald Trump turned America’s back on the Paris Agreement, Australian families decided that investing in solar energy for their homes and businesses made sense, in fact Australia has the highest take-up rate in the world.
The NSW Office of Environment and Heritageis keen to build on that and have just been in the region, dropping in on towns where the take up of solar panels hasn’t been as great as it has been in other communities.
Free community seminars in Queanbeyan, Cooma, Eden and Ulladulla have helped “Demystify Solar Power’.
OEH staff were on hand to answer questions and lead discussion – explaining the different options for businesses and households wanting to switch to solar; saving money and saving the planet.
The Paris Agreement was part of the conversation that took place at these seminars, but this all happened just before Trump quite, not that I think the local response would have been different.
Mark Fleming, from OEH said the seminars will explain in plain-English the different types of solar technology available and the trends in solar power use in Australia and around the world.
“We had such a positive response to the last seminars that we are again encouraging people to come along and get the info they need to make decisions that are best for their circumstances,” Mr Fleming said.
“We’ll also explain the different options available for local businesses wanting to switch to solar and save money on bills.
“Businesses and households often get unsolicited approaches from companies wanting to install solar panels and while most people agree that solar is a good thing, it’s hard to compare these offers.
“At the seminars, you’ll find out the exact questions you should ask suppliers if you are thinking about installing solar panels,” said Mr Fleming.
Mark Fleming talks to About Regional, click play…
Around 800 people attended the seminars held last year across the region and since then more than 50% of those surveys have either installed solar or are in the process of getting quotes.
“Our goals to make people comfortable to ask the questions on their minds and leave with a much clearer understanding as to if solar is right for them,” Mr Fleming said.
