Aussies called to action as council issues warning over 'aggressive' invasive weed
The creeper, which features bright yellow flowers, 'spreads faster than airport gossip and strangles everything in its path, including your poor native plants', it warned, urging homeowners who find it growing in their yards to 'act now'.
The ornamental 'takes over gardens' and 'loves neglected areas', the council explained. The species is found in coastal areas of northern and eastern Australia, but it is most common in southeastern Queensland — where it is regarded to be a significant environmental weed — and northeastern NSW.
In the Sunshine State, the Singapore daisy (Sphagneticola trilobata) is a category three restricted invasive plant under the Biosecurity Act 2014, and must not be given away, sold, or released into the environment. It is also a weed in NSW and is not allowed to be sold in parts of the state.
Council targets invasive weed in winter campaign
Gympie Regional Council said the species, which is featured on the IUCN's list of the world's 100 worst invasive alien species, is one of five weeds it's targeting in its Winter Weeds campaign.
'Winter is prime time for targeted herbicide treatment, especially while soils are dry and the plant is still active,' it said.
Singapore daisies can be removed by hand, as long as all cuttings are burned or disposed of properly. Aussies should place waste in a plastic bag and then leave it in the sun for a few days before putting it in the rubbish bin. Certain herbicides can also be applied to destroy the plant.

Council finds 'significant' invasive weed in Aussie garden
Earlier this week, biosecurity authorities in Queensland revealed a 'vigilant' council worker had stumbled upon a 'significant" invasive weed and several other prohibited species in a homeowner's garden.
A land protection officer for Bundaberg Regional Council was wandering near the property when they spotted three mature yellow fever trees — a potentially dangerous weed that is banned in the state over fears it could become a major pest.
The concerning sight prompted the council worker to alert authorities, and additional prohibited species were later located in the yard. In total, 31 problematic trees, along with thousands of seeds and seedlings, were removed and destroyed.
What are yellow fever trees?
Yellow fever trees are native to southern and eastern Africa, but like most of Australia's environmental weeds they were introduced to the country as ornamental plants. They can grow up to 25 metres tall and have a smooth bark coated in a greenish-yellow powder that can easily rub off. Its name is believed to reflect the bark and the plant's tendency to grow in swampy areas of Africa, where malaria is common.
While yellow fever trees have been found in gardens around the country, the species doesn't appear to have naturalised. However, due to concerns it could escape cultivation and spread, the Queensland government has deemed it a target for eradication.

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. "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. 🌱 How Aussie farmers are turning the tide on $4.43 billion weed problem 🌸 Warning not to touch invasive weed 'growing everywhere' in Aussie suburb 🚙 Alert issued to residents, travellers after dangerous find on side of roads 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". Do you have a story tip?
