When I first knew this forest it’s flowers were strange.
the thick fleshed Murray-lily, flame tree’s bright blood,
When first I knew this forest, time was to spend,
Now that it’s vines and flowers are named and known,
My search is further. There’s still to name and know beyond the flowers I gather that one that does not whither- the truth from which they grow
It is not OK to let your dogs chase wildlife
A swamp wallaby joey is being cared for by WIRES volunteers after being rescued from dogs at the beach at Suffolk Park last weekend.
“Jaz scooped up the exhausted joey in a towel with the dogs still trying to attack it, and all in front of the dogs’ owner,” Sarah Nagel, Council’s Manager Public and Environmental Services, said. “Our staff then called WIRES and from all reports the joey is recovering well,” Ms Nagel said.
“We are very thankful to Jaz and WIRES for saving and caring for the joey and it’s a reminder to dog owners to please do the right thing and keep their pets under control whenever they are in a public area,” Ms Nagel said.
Work has also started on a Dogs in Public Spaces Strategy. This will focus on resolving the issues and challenges of managing dogs in public spaces in the Byron Shire.
“Our public spaces need to be safe for everyone and some dog owners need to realise that not everyone likes or is comfortable around dogs,” she said.

Salvinia weevils released in Tallow Creek catchment to control invasive weed
Byron Shire Council and Rous County Council have released Salvinia weevils into the Tallow Creek catchment as a biological control for the invasive Salvinia weed.
Salvinia weed, also known as Salvinia molesta, grows very quickly and can double in size every couple of days, taking over waterways and lowering oxygen levels in water that fish need to breath.
The Salvinia weevil is bred by the NSW Department of Primary Industries (DPI) in Grafton as a biological control and natural alternative to chemical spraying.
Each female weevil is capable of laying 300 eggs and both the adult and larval stages of the weevil lifecycle help to kill the Salvinia plant.
The weevils do not feed on native plant species and when there is no Salvinia left the weevils will die.
Chloe Dowsett, Council’s Coast, Biodiversity and Sustainably Coordinator said weevils have proven to be an effective control however they are not a quick fix, often taking many months for results to be seen.
“In 2019 we released weevils into the lake at Waterlily Park at Ocean Shores and they successfully reduced a Salvinia infestation to very low levels which allowed for the growth of a native aquatic plant.”
“We strategically released the weevils into an upstream location of Tallow Creek with lots of green growth in the hope that this will provide a good habitat for them to reproduce and create a colony,” she said.
“The recent opening of Tallow Creek, saw some of the weed washed into the ocean and we know that this species does not like the salt water which is good news,” Ms Dowsett said.
Council will continue to monitor Tallow Creek, by checking the Salvinia for any signs of bug activity like brown or damaged new growth buds.
“The weevil was a great success at Waterlily Park but this does not mean it will work as well at Tallow Creek,” Ms Dowsett said.
“We will have to wait and see if they will do their job in their new home in Tallow Creek,” she said.
“With the holidays about to start it’s a timely reminder for people to check equipment like kayaks and stand-up paddleboards because this is often how Salvinia is introduced to waterways.
“And people should never throw any weeds from fishponds or tanks into waterways either,” Ms Dowsett said.

Wild bilbies found in Currawinya National Park for first time in 70 years
ABC Western Qld Ellie Grounds
No bilbies had been spotted in the wild on the park, on Budjiti country near the NSW border, about 830km west of Brisbane, since the 1950s. Save the Bilby Fund charity breeds bilbies, which are endangered in Queensland, in captivity and then releases them into a 25-square-kilometre fenced enclosure on Currawinya.
The enclosure has been free of feral cats since 2018.
Now there are more than 200. https://www.abc.net.au/news/2021-11-25/wild- bilbies-found-outside-currawinya- fence/100628724

FROM TRASH TO TREASURE
WERRIBEE TIP TO TURN RUBBISH INTO ELECTRICITY
ABC News Margaret Paul
50% of waste brought to the waste facility will be sorted using a conveyor belt of magnets and machines, dividing the waste into things that can be re-used or recycled, and green waste.
The other part of the council’s plan is sorting the green and organic waste and starving it of oxygen, then turning the methane that is produced into electricity.
Waste to energy is a good way of both dealing with waste and creating energy.
We need to think about ways and means we can reduce resources, such as single-use plastics, composting garden waste and household organics.
Ultimately the reduction of waste in the first place is the key.
Sydney waste research scientist Veena Sahajwalla awarded NSW Australian of the Year 2022

The Australian Research Council laureate pioneered the process of turning waste into “green materials”.
This breakthrough has been patented around the world and has diverted millions of old tyres — which would otherwise take decades to decompose — from landfills.
AUSTRALIA’S NATIVE WILDLIFE IN GRIP OF UNPRECEDENTED ATTACK
·There are up to 6 million feral cats and 23 million feral pigs in Australia.
·From 1960 to 2017, invasive species cost Australia at least $390 billion.
DID YOU KNOW?
Feral cats and foxes have killed off 25 native mammal species.
More than 2700 weed species make up 12 per cent of Australia’s flora.
Fire ants are one of the worst invasive species in Australia.
WHAT CAN YOU DO?
Follow the rules for biosecurity when returning home from interstate or overseas.
Grow native plants in your garden; remove weeds and look out for those that pose a biosecurity risk to Australia.
Be alert for signs of disease in farm animals and stock.

A HOPE FOR LYME DISEASE? NEW VACCINE TARGETS TICKS
MRNA technology is now famous for delivering vaccines against COVID-19, and this week it achieved another distinction with an experimental Lyme preventive announced by the collaboration launched in Ireland. “It’s the first vaccine [intended for humans] against an infectious disease that does not target the pathogen,” Fikrig says. The mRNA vaccine, administered to guinea pigs, turned tick bites red and inflamed. The ticks fed poorly, fell off early, and often failed to transmit the Lyme- causing bacterium. Researchers hope the vaccine will one day work the same way in humans.
Biodegradable ‘flat-pack’ homes to help wildlife survive after bushfires
It’s the latest flat-pack innovation – a biodegradable shelter that can be rapidly installed to provide refuge for native animals left exposed and vulnerable after a bushfire. Newly designed ‘habitat pods’, developed by Dr Alex Carthey of Macquarie University, are this week being deployed as part of a world-first Australian Wildlife Conservancy research project at North Head Sanctuary.
The habitat pods themselves take the shape of a sturdy, six-sided pyramid made from folded cardboard, perforated with multiple small holes where animals can scamper in and out. Unlike the wire and shadecloth structures that have been used as post-fire shelters previously, the pods are light, easy to transport and set up, and entirely biodegradable.
NEW RESEARCH LINKS AUSTRALIA’S FOREST FIRES TO CLIMATE CHANGE
CSIRO scientist, Dr Pep Canadell, said the research was one of the most extensive studies of its kind performed to date.
“While all eight drivers of fire-activity played varying roles in influencing forest fires, climate was the overwhelming factor driving fire-activity”. “The results also suggest the frequency of forest megafires are likely to continue under future projected climate change.”
Over the last 90 years, three of the four mega fire years occurred after the year 2000. A mega fire year is defined as the cumulative burned area of forest over one year of more than 1 million hectares.

This La Niña is expected to be relatively weak and short-lived, but with many catchments already full following a La Niña last summer, as well as a wet winter and spring, its impacts could still be severe.
La Niña means wetter-than-average conditions are favoured over the north and east.
Large scale renewable hydrogen project proposed for South Australia to target international export markets : EcoVoice – Environment News Australia
Kallis Energy Investments is developing the Moolawatana Renewable Hydrogen Project – a large scale (up to 6000 MW) combined solar and wind farm to produce low-cost renewable (or green) hydrogen on Moolawatana Station in the north of South Australia (SA)
The project is expected to involve around 3000 MW of solar and 3000 MW of wind power generation, together with electrolysers and desalination plant to produce green hydrogen which would be transported via a dedicated hydrogen pipeline to, or near Port Bonython and transformed into green ammonia ready for shipping to overseas markets.
FARMERS AND MINERS JOIN CLIMATE CHANGE DEBATE TO REACH NET ZERO BY 2050
ABC Rural By Ashleigh Bagshaw
Farmers and miners often feel they are not included in conversations around climate change. A psychology student has launched a campaign to highlight the voices of those most impacted by climate change
The agriculture industry is central in Australia’s path to net zero.
The federal government forecasts up to 17 million tonnes of carbon dioxide equivalent could be sequestered in soil carbon projects by 2050.
“We need to be putting those funds into programs that are going to hold up more water, that are going to increase ground cover, that are going to help us to build our carbon back in our soils.

The power of poo
Landline by Jon Daly
Slurry tankers, as they are known, are not new in Australia, but few can efficiently inject effluent into the soil at scale.
Implements towed behind it inject effluent 20-30 centimetres into the soil.
Mr Young said finding new technologies such as his slurry tanker could improve fertiliser efficiency and reduce run-off.
The broader agriculture industry is also taking notice of this novel approach.

Why soil carbon equals better nutrient cycling
A healthy biome involves communities of microbes interacting with each other and plants for mutual benefit.
Fungi and their relationship with bacteria and roots are the warp and weft of the fabric that creates the cloak that we call soil that sustains the earth.
Fungi provide hyphae highways transporting food and water to bacteria and plant roots.
WEED OF THE MONTH
A large tree with grey to rusty brown bark that is shed in flat discs. Its needle-like leaves (17.5-30 cm long) are grouped in twos or threes and held within a sheath at their base. Its elongated male cones (2.5-6 cm long) are borne in clusters. Its large female cones (7-20 cm long and 3-7 cm wide) are borne on short stalks. These cones have small prickles on the tips each of their woody scales.
This species is becoming widely naturalised in the sub- tropical regions of eastern Australia.
Cut and remove small trees – they can make great Christmas trees. Cut at ground level, no need to poison after cutting. Ring bark large trees by removing thick bark to the cambium layer. The tree will slowly die.
Remove large trees by arborist and chip. Foliar spray seedlings with Glyphosate 1:50
