Region's battle to tackle sinister threat lurking at popular waterfall near border
One region, which sits close to the border of Queensland and New South Wales, plays a key role as one of the "front lines" between the two states. Workers have now issued a reminder, saying everyone has a role to play in the fight to protect our bush and stamp out invasive species.
"It's really important that everyone is vigilant so we can identify new and emerging threats and jump on them early," Philip Courtney, Rous County Council's Weed Biosecurity and Bush Regeneration Manager, told Yahoo News.
Rous County Council manages the weed biosecurity for six Northern Rivers councils. It is trying to control several invasive plant species. At the picturesque Whian Whian Falls, plants like giant devil's fig, lantana, and both small and broad-leaved privet were removed so that native plants have enough space to thrive.
"What we're trying to do is enhance the natural beauty of the area and encourage native species to grow," Courtney said. "It also helps with water quality. The better the catchment and surrounding areas, the better the water quality will be."
Weeds thrive in 'perfect climatic conditions'
Australia's ecosystem and climate make for "perfect conditions" for the growth of plants and "unfortunately, lots of weeds", Courtney told Yahoo. He said Rous has a "very important" and "never-ending" job tackling weeds that enter the ecosystem.
A recent infestation of prohibited plant frogbit is a recent example. While legal to possess in Queensland, the floating aquatic plant is illegal to buy, sell, trade or move into NSW, with on-the-spot fines of $2,000 for doing so.
Another focus area is parthenium weed, another prohibited plant in NSW.
"There shouldn't be any in NSW. However, we've already found a couple of sites in the Northern Rivers region, and we've been able to jump on them early," Courtney said.
Miconia calvescens, which forms large monocultures and can cause land slips, and tropical soda apple, which is spread through cattle, are two more.
Rous County Council was recently granted $85,000 from the NSW State Government to tackle bitou bush, and other weeds at three sites in the Ballina Shire Council area.
"We are the front line for the rest of NSW to eradicate and stop these weeds early so they don't become a problem for our region and the rest of the state," he said.

And it's not just plants that pose a threat, with the area also on high alert for the spread of fire ants. There have been several breaches outside containment lines recorded across the country, including in northern NSW, in recent weeks.
Residents impacted by an outbreak of the "world's worst" invasive species fear they may lose access to their own backyards, as the pest marches into new territory.
Courtney has urged Aussies to educate themselves on the native fauna and flora.
"Inform yourself of what's in your backyard and in your local area," he said. "If there is anything that you don't recognise, report it to the authorities as quickly as possible".

Australia called out after approving 'ridiculous' airport plan
Australia will allow an airport in the nation's capital to build an asphalt road through one of the last three known places where a rare native animal is found. Although once common in the ACT, fewer than 100 Canberra grassland earless dragons survive in the wild, primarily because the flat plains it inhabits have proved popular with developers. On Wednesday, the government quietly published news that the federal environment minister had green-lit Canberra Airport Group's Northern Road project. Late on Friday, his department confirmed the decision to conservation groups that had campaigned for the road's construction to be stopped. One of the campaigners was Dr Simon Copeland, the executive director of Conservation Council ACT Region, who argues the government's timing appears to have been designed to 'hide' the controversial announcement. 'Last term, the federal government declared it wanted no new extinctions. But scientists have been raising the alarm that this species is on the verge of extinction, and we need to be doing everything in our power to protect its habitat,' he told Yahoo News Australia. 'Now we have a government that's decided to do the complete opposite of that.' Sad decline of the grassland earless dragons The Canberra grassland earless dragon was thought to be extinct until its rediscovery in 1991. It's one of four similar dragon lizards that were thought to be one species until 2023, and all are threatened with extinction. Around Australia, less than 1 per cent of their habitat remains. All are in serious trouble in the wild, and the Monaro species is the only one listed as endangered rather than critically endangered. The Victorian species was rediscovered living on a small parcel of land that is yet to be protected by the state government. And the Bathurst species hasn't been seen since the mid-1990s, and while it may be extinct, there are searches underway along farmland and roadside verges where it's hoped isolated populations may have survived. The federal department of environment (DCCEEW) concluded that works to the north of Canberra's airport across 0.68 hectares of natural temperate grasslands are unlikely to provide quality habitat for dragons because it's actively maintained as a roadside verge. It believes plans to restore 6.67 hectares of habitat would result in a conservation gain for the species. What concerns conservationists most about the road plan isn't the loss of 0.68 habitat, it's the fragmentation of the landscape. Because the three Canberra grassland earless dragon populations are so small, there are concerns about them becoming inbred. Airport claims road will not fragment dragon habitat Copeland doesn't believe the road will mean the end of the dragons, but he's concerned it will push them further towards extinction. 'When you have a small population already and you split it in half, it makes it harder for them to breed and increase genetic diversity,' he told Yahoo News Australia. To combat these concerns, Canberra Airport Group has agreed to fund a $1 million grant to support the ACT Government's recovery program, which includes captive breeding and reintroduction activities. It will also build barrier fencing to help prevent vehicle impacts, and underpasses, which it's hoped will encourage the dragons to cross under the road. In a statement, Canberra Airport said DCCEEW's approval of its plan confirms 'there's no increased risk of extinction and no fragmentation'. It has committed to moving ahead with the project in the coming months. But Copeland disagrees that there will be no habitat fragmentation. 'It's just ridiculous, quite frankly,' he said. 'It's very clear that if you look at their own maps, there's dragon habitat on either side of the road. They have nice ideas. They have barriers and bridges under the road. But there's no evidence they'll work. No one has done any research to figure out whether the lizards will use them.' 🐕 ACT government admits to unlawfully trapping dingoes for years 🐸 Alarm raised after strange backyard phenomenon worsens in Aussie region 💰 NSW spends $11.7 million on protecting three incredible destinations Road construction will 'improve traffic management' Yahoo News contacted Environment Minister Murray Watt's office with several questions about the matter. It responded with a statement from a government spokesperson, which said DCCEEW had 'consulted extensively' with the community and 'relevant species experts' and that the decision would 'improve traffic management' and provide 'stronger environmental protections'. 'The varied approval provides stronger protections for the species through several new conditions considered necessary to avert long-term decline,' it said.

Region's battle to tackle sinister threat lurking at popular waterfall near border
Australia's biosecurity rules are widely regarded as some of the strictest in the world. Yet, invasive species including plants and predators continue to be a major issue spreading across our vast landscape, choking native ecosystems and outcompeting our animals. One region, which sits close to the border of Queensland and New South Wales, plays a key role as one of the "front lines" between the two states. Workers have now issued a reminder, saying everyone has a role to play in the fight to protect our bush and stamp out invasive species.

Rotting estate sparks call to ‘build new properties on the land'
Built in the 1970s to provide sheltered housing, the Maes Emlyn estate in Rhyl once offered 59 homes for local residents. Named after Emlyn Williams, who chaired Rhyl's Housing Committee for nearly 20 years, the estate was seen as a vital part of the community. North Wales Live readers would like to see improvements to the site. Time hasn't been kind to Maes Emlyn. The homes, not built to last, were declared unfit for purpose and vacated by August 2021. Since then, the estate has stood empty, slowly crumbling under the elements. A recent video by urban explorer Adam Mark revealed the extent of the decay, showing broken windows, peeling walls, and overgrown surroundings. Denbighshire County Council had once floated the idea of using the site for temporary homeless accommodation, but this was met with opposition from locals and ultimately shelved. Now, residents are growing increasingly frustrated with the site's continued neglect and are calling for action. READ MORE: Seaside parking charges slammed as 'just more anti-car money grabbing' READ MORE: Holiday let owners hit by council tax bombshell told 'pay up or sell up' With a housing shortage pressing across the region, many are urging the council to act swiftly. In response, a council spokesperson confirmed that a consultation on redevelopment took place late last year. They added that revised proposals for new housing on the site would be shared with the community soon. The proposed plans would see the derelict estate demolished and replaced with 35 new flats and family homes — a move that could breathe new life into the area and honour its original purpose of providing shelter and stability. Commenter Everyyear says: 'Obviously the estate needs to be rebuilt or repaired to the point where it is habitable once again. I suppose the challenge is finding the money to do the work? Logically speaking, the amount of money saved (from housing people in emergency accommodation) could more than pay for the work. Perhaps some of the grant that has been allocated to Rhyl could be used? Then the savings could repay the investment back to the grant fund or reinvested in future housing development? I doubt the funding arrangements are straight forward but where there is a will there is a way!' Statistix states: 'I find it infuriating that councils eagerly grabbed at council tax premiums on second homes and holiday lets in the hope of either making a huge profit or pushing owners into selling to cover their shortfall of 'affordable homes', but put lower premiums on many more eyesore long term empty homes. This does little to encourage absentee owners to repair/reuse/redevelop.' Robbie thinks: 'They should be kept as an asset and fixed up. It's a disgrace they weren't maintained when locals are desperate for homes.' Dave selwood suggests: 'Give the land to a housing association, they will develop it within a year.' Cooperman1927 points out: 'They have asbestos in them and are dangerous.' Jonesey1 replies: 'That's another cost to add on then. Maybe knocking them down and starting again really is the answer but where the money will come from is anyone's guess.' Vaux08hall adds: 'The answer is to build new properties on the land and stop building on farmland.' Vaux08hall agrees: 'Absolutely and there are plenty of brownfield sites around North Wales.' HoorahHenry1 asks: 'I thought the Labour Government was planning to spend billions on housing, so really it should not be difficult to refurbish these properties?' Jeff2509 retorts: 'This is the local council's responsibility and is not down to the central government or the Senedd. If you are looking to play the blame game, it's really locals who have blocked movement on this estate.' How do you feel about seeing this estate fall into neglect? What do you think should be done to bring it back to life? Share your thoughts with us in the comments.
