Fears invasive species is spreading as Aussie mates stumble upon 'fairytale' scene

Fears invasive species is spreading as Aussie mates stumble upon 'fairytale' scene

Yahooa day ago
A group of Aussie mates were cycling through a dense forest earlier this month when a fairytale-like scene suddenly appeared in front of them, prompting the mesmerised group to leap off their bikes and take a closer look.
Sean Blocksidge and his friends couldn't believe their eyes when they spotted the cluster of three bright red and white mushrooms sprouting from the ground near Margaret River, south of Perth.
'We were all amazed at the size of them. Almost double the size we've seen in the past,' Sean, who snapped photos of his size 14 foot next to the fungi to highlight their size, told Yahoo News. However, a grim truth lurks behind the mushrooms' alluring appearance.
'Despite their fairytale looks, they're a toxic, invasive species,' Sean, the owner and operator of the Margaret River Discovery Company, revealed.
Amanita muscaria — better known as the fly agaric — is an introduced fungus that is believed to have come into Australia on the roots of pine plants. The species, which is toxic to people and pets, is commonly found along the country's east coast, Tasmania and in parts of South Australia and southwest Western Australia.
While it's made its presence known since arriving in the early 20th century, Dr Carol Booth, policy director for the Invasive Species Council (ISC), told Yahoo amanita muscaria 'has only recently been discovered in WA'.
An article published by the state's Department of Environment and Conservation notes an increase in reports of the fly agaric popping up in pine plantations, gardens and parks in 2012.
Toxic mushroom species 'more noticeable in recent years'
Sean told Yahoo that although the 'invasive mushroom has been around for a while', it 'seems to be more noticeable in recent years'. Amanitas have been sprouting throughout the pine forests around Margaret River, Busselton, Pemberton and Nannup region over the past few weeks, he explained.
'This year is the most prolific and biggest size I've ever seen them,' he said. 'Almost double the size of previous years and most likely a result of some solid winter rain events.'
While they are 'beautiful', Sean noted they're not great for native ecosystems — a sentiment shared by Dr Booth.
'That said, they've certainly made themselves at home in WA's introduced pine forests and look quite magical when you do spot them!' However, they are best admired from a 'safe, non-eating distance'.

🪴 Aussies urged to dig up invasive plant that becomes 'very difficult to remove'
Invasive mushroom can displace native fungi species, experts say
Professor Brett Summerell, chief scientist at Botanic Gardens of Sydney, told Yahoo amanita muscaria is considered to be a 'weed mushroom' given it can displace native species of fungi, similar to invasive plants.
Booth said the species 'forms mutually beneficial relationships with several exotic tree species', providing them with water and nutrients in exchange for carbohydrates.
'In Australia it has spread into native forests by jumping from exotic hosts to a native tree — the southern beech — and it may also jump to eucalypts, as it has overseas,' she said. 'This raises concerns that it could displace native fungi and alter the availability of nutrients for the trees it colonises.'
Summerell said the mushrooms often appear from April through to July and can vary in size. 'I have seen them up to 30cm in diameter. They generally are larger in wetter years,' he explained.
Their common name — the fly agaric — arises from the practice of placing the mushrooms, or powdered forms of the mushroom, in milk to attract and kill flies and other insects.
'The mushrooms can be toxic, although there are some who consume them for psychoactive properties, but it can be quite risky. Generally, they are not considered deadly,' Summerell said, adding the species has been 'been used in art and literature from the Renaissance', and is one of the mushroom emojis on your phone.

Cannabis And Psychedelics Seen As Effective For Eating Disorders, Study Finds

Anorexia Nervosa - Common Medical Marijuana Conditions for Qualifying Patients - use of the whole, ... More unprocessed marijuana plant or its basic extracts to treat symptoms of illness and other conditions. A new study has found that cannabis and psychedelics are perceived to be the most effective drugs that help alleviate eating disorder symptoms. A group of researchers from the University of Sydney has conducted a survey on over 6,000 people suffering from eight eating disorders, such as bulimia, anorexia, and binge-eating disorder, and found that most of them rely on cannabis and psychedelics to help alleviate their symptoms. Published on JAMA Network Open-Psychiatry this week, the study tried to understand which prescription and nonprescription drugs are used by people with eating disorders, and how they are associated with symptoms. To do so, participants, diagnosed with eating disorders and mainly from English-speaking countries, completed an online survey on recent prescribed and nonprescribed drug use, as well as perceived benefits and harms. Initially, 7,648 respondents were recruited; 6,612 completed demographics, and 5,123 finished the survey. The findings of the survey showed that overall, the best-rated drugs for eating disorder symptoms among respondents were psilocybin, cannabis, and lysergic acid diethylamide. For example, for respondents with anorexia, cannabis received the highest rating. When asked to identify their drug of choice for self-medicating eating disorder symptoms, the most popular drug among respondents was cannabis, but when normalized by number of users, fluoxetine, an antidepressant, ranked highest. Among 6,136 respondents, prescription psychotropics were rated highest for mental health. Psilocybin, LSD, and cannabis also received strong ratings. 'A striking outcome was the favorable self-reported ratings of psychedelics and cannabis for alleviating ED symptoms, eclipsing the ratings of commonly prescribed psychotropics,' the study reads. Can Cannabis Help Alleviate Eating Disorder Symptoms? The study also highlighted that daily cannabis users reported perceived benefits for their eating disorder symptoms. Researchers said that 'there is scant research around the use of cannabinoids in individuals with eating disorders apart from small trials supporting the efficacy of dronabinol, which is synthetic tetrahydrocannabinol, in those with anorexia nervosa.' They also added that cannabis may benefit people with restrictive and food-aversive eating disorders, like anorexia nervosa and avoidant/restrictive food intake disorder, 'by increasing the hedonic value of food.' This is in line with previous studies on the effects of cannabis on appetite. A study published last year showed that mediobasal hypothalamus (MBH), a region in the brain that regulates various physiological processes, controls increased appetite following cannabis use. In contrast, cannabis received poor ratings from people with bulimia and binge-eating disorder, likely because its appetite-stimulating effects can trigger or worsen binge-and-purge behaviors, thereby intensifying the symptoms of the eating disorder. Psilocybin and LSD were consistently rated highly across all diagnostic groups for their ability to improve eating disorder symptoms, enhance overall mental health, and be well tolerated. However, the study has several limitations. The survey primarily included participants from high-income, English-speaking countries with internet access. It may have also attracted people with eating disorders who are more inclined toward new ways to treat their eating disorder symptoms or have positive attitudes or prior positive experiences with drugs. Furthermore, diagnoses were based on self-report rather than formal clinical assessment, and comorbid conditions were not evaluated. Additionally, recall bias may have influenced participants' reports of drug use and symptoms. Therefore, because some findings are based on small sample sizes within specific diagnostic related to eating disorders and drug-use groups, the researchers highlighted that this study's results 'should be interpreted as exploratory rather than definitive.'

Tackling dementia: New approach urged

Urgent action is needed to fight the 'darkness' of dementia, as the deadly condition threatens to affect 850,000 Australians by 2058, a leading brain researcher has said. Dementia is estimated to cost Australia's economy $18bn each year, a figure that will more than double to $37bn in 25 years. But Professor Henry Brodaty spoke to the National Press Club on Wednesday about the need for a new approach to tackling brain health. He said tackling the syndrome would increase productivity in Australia, and delaying the effects of it would allow people to work longer, especially as the workforce ages. A new approach was needed with increased investment to become a world leader in preventing or delaying dementia onset, he said. 'Think about the slip, slop, slap for skin health,' he said. 'We need the slip, slop, slap of brain health, now. 'Funding for dementia has lagged behind cancer and heart disease, even though it contributes more to disease burden. 'Research is critical to find the best ways to provide services efficiently.' He said dementia develops in Aboriginal Australians and Torres Strait Islanders at 2-5 times the rate of the rest of the population, and suggested steps to counter this. 'Better care before, during and after pregnancy, and in early childhood, and particularly more education, could make a difference to this,' he said. Professor Brodaty said personalised coaching programs improved brain cognition, and increased people's fitness — pushing back the onset of dementia by a year or more. He said this could save Australia billions. 'Imagine what the return on investment would be if Australia did this?' he asked. 'Improving fitness, not only would improve cognition, it would improve fitness, physical, mental and social health.' But Professor Brodaty said Australia's National Dementia Action Plan has only $166m in funding, 'too little for what Australia needs'. 'I sympathise with the government, because there's always competing priorities and there's always other things that can be funded,' he said. 'But, when it makes sense economically, as well as personally to people, then why not do it?'

Plea to Aussie councils after common roadside problem exposed in photo

Australia's network of roads can be plain ugly, so what could be prettier than a local council planting a bed of pretty flowers across the surrounding nature strip? Unfortunately, experts have identified an often overlooked problem created beside one roundabout, just 6km west of Melbourne's CBD, where instead of local native plants, 'highly invasive' gazanias have been planted. Dr Ali Bajwa's Weed Science Group at La Trobe Institute for Sustainable Agriculture and Food has been investigating the impact of the species on the environment and agriculture, and he believes they are 'problematic'. The plant spiked in popularity in Australia during the 1950s and 1960s, but despite its known problems, it continues to be sold in nurseries and planted by councils. 'They spread quite rapidly. We've seen places where they've covered everything and replaced all of the remnant vegetation. They were introduced as ornamental plants, mainly grown in gardens and nature strips, and we believe that's where they've spread from,' he told Yahoo News Australia. Gazanias are known for their fierce growth, which ensures the species smothers native groundcovers and wildflowers, leading to a loss of native plant diversity. While its flowers and leaves are pretty to look at, they provide little habitat or food for native animals or insects. The plant can spread through garden waste, or via seeds or root systems when it's in the ground. Although some modern species have sterile seeds and this helps restrict its impact on the environment. Gazania is now a common sight along roadsides, particularly in Victoria and South Australia. When the species invades paddocks, farmers struggle to manage its spread, as standard herbicides are generally ineffective. Bajwa believes the 'horse has already bolted' when it comes to the invasion of gazania, but that doesn't give gardeners an excuse to plant more. The problem is clearly bigger than just one cluster, pictured on the side of the road in Footscray. 'Councils should be thinking of replacing them with more desirable species, like natives, which can grow well under the same conditions,' he said. Will the roadside gazanias be removed by council? Some local governments have already pulled them out to try and help the environment, but others are yet to do so. There doesn't appear to be any immediate plans to remove the gazanias or the invasive agapanthus growing in the roundabout in Footscray. Maribyrnong City Council, which manages the nature strip, did not respond directly to questions from Yahoo News about whether it was aware of the gazanias, why it was allowing them to flourish, or what it planned to do about the problem. 'Council uses a variety of native and non-native species in open space plantings to suit the character of different areas,' its CEO Celia Haddock said in a statement. 'Council does not plant declared noxious weeds and we continue to look for opportunities to prioritise native plants, and improve planting practices where suitable.' How councils can avoid spreading invasive plants To avoid the spread of more weeds into Australia's fragile environment, the Invasive Species Council (ISC) advises that local governments should opt for native plants. Speaking generally about the issue, spokesperson Imogen Ebsworth said there's simply not enough information available as to what has become invasive, or is likely to in the future. 'The result of that is that councils then sometimes find they've inadvertently planted an invasive species that then becomes a problem for them to manage on their own land, and also impacts others,' she told Yahoo. 'A way for councils to address this would be to really focus on plants that are natural to the local area, and are not invasive.' 🚨 Invasive species photographed destroying Aussie bush 🧪 Scientist's 'time capsule' in vault key to resurrecting Aussie species 🔎 Rare species with less than a thousand in the wild tracked down The ISC's solution to the problem is to approve national regulations that would prohibit the sale of invasive plants, taking the onus off councils and home gardeners to know what is problematic. 'We've got a situation where over 75 per cent of the invasive weeds we deal with have started their life as garden ornamentals, and a lot of them take 50 years or so for it to become clear that they're really invasive,' Ebsworth said. 'So we've got this huge time lapse gap where we've got over 30,000 introduced plants into Australia, most of them have not been assessed for whether they are weeds or could become weeds. So the information is really imperfect for decision makers. At the local council level, that means good intentions sometimes turn into invasive problems.'
