It’s  been nearly two years since  fall armyworm was  first  detected in Australia, and in that time  the  pest  has made its presence felt. With the ability to travel vast distances of up to 100 kilometres overnight, and an appetite for summer crops, the fall armyworm can devour large quantities of crops  – including ginger – in  a matter of days.  

The latest issue of Australian Zoologist is titled “Out of the ashes: Lessons learned from bushfires and how we can better manage our fauna”. But the editorial wrap-up suggests we’ve learnt nothing. It seems our fauna will continue to suffer from mismanagement under a Lock It Up and Let It Burn conservation’ paradigm. The abstract mentions monitoring, mapping and research, but the only reference to management is “use of supplementary resources such as nest boxes and artificial roosts to replace those lost in fires”.

In two decades, the number of people who die of a heart attack in our region has plummeted by more than 20 percent – thanks to visiting cardiologist Philip Tideman and longtime rural GPs at Kincraig Medical Clinic. In Naracoorte alone, more than 500 people have benefited from their work. Now Naracoorte and the SE are being recognised nationally and internationally for reducing death rates from heart attacks in country areas.

Climate change threatens our forests, but it is not necessarily an existential threat, according to a leading Australian scientist. “It’s not necessarily the case that we will be wiped out by wildfire. The existential threat of fire can be mitigated, but we must use ALL knowledge,” Mark Adams, Professor of Bioscience and Innovation at Swinburne University of Technology ... This included indigenous people’s use of fire as a management tool.

Charles Sturt academic, Dr Joanne Connolly explores what makes koalas unique and how Charles Sturt University is contributing to saving endangered populations, including research into the Narrandera koala population ... ARR.News asks some questions of Dr Connolly.

Bushfire affected environmental recovery monitoring in south-west NSW by a Charles Sturt University PhD research student has revealed a hitherto un-noted lizard species in Woomargama National Park. Mr Grant Linley in the Charles Sturt  Gulbali Institute of Agriculture, Water and Environment  said his research obtained photographic evidence of a species, the  heath goanna  (also known as  Rosenberg’s goanna), in Woomargama NP which has not been observed by scientists to occur in the park.

Exceptional growing conditions and high global prices are continuing to benefit Australian agricultural production and exports. The ABARES September quarter Agricultural Commodities Report is forecasting agricultural export earnings to climb to a record $70.3 billion for 2022-23 – almost 50% more than what it was 10 years ago after accounting for inflation.

Marine ecosystems and coastal communities will benefit from increased investment and restoration projects as a result of the new NSW Blue Carbon Strategy ... “The simplest way to understand blue carbon is to liken it to underwater forests – just as trees store carbon, marine and coastal plants and ecosystems do too, except even more efficiently” : Minister for Environment, James Griffin.

The resistance of  green peach aphid (Myzus persicae,  GPA)  to numerous chemical mode of action groups makes it an ongoing management challenge. In Australia, GPA has evolved resistance to synthetic pyrethroids, carbamates, organophosphates, neonicotinoids, and quite recently, to sulfoxaflor. And now, Australian researchers have found populations of GPA with resistance to spirotetramat, the active ingredient in Movento ® 240 SC Insecticide, as well as several generic products containing the same active ingredient.

Huge interest in new non-energy products based on brown coal shows the big economic opportunity for the Latrobe Valley as the region transitions away from the power industry, according to an industry leader. The chief executive of Australian Carbon Innovation, Brian Davey, said ACI recently went to the market with expressions of interest, looking for projects in the carbon area using the Latrobe Valley's brown coal.

Mount Alexander Sustainability Group’s Healthy Soils team is looking for commercial farmers with soil issues within a 50-60km radius from Castlemaine. This Healthy Soils Project offers the opportunity for 20 participating farms to receive free soil constraint assessments and soil testing, as well as assistance with developing a soil health management and monitoring plan.

Keith Blaikie. In order to keep our students at the centre of the school’s vision, which is to be an inclusive community committed to high levels of learning for all, staff have been engaged in a body of research known as the Science of Reading.

Vincent Savolainen. Professor Vincent Savolainen has come back to Lord Howe Island to set up new research about the role that underground fungi may play in generating and maintaining plant diversity ... Our understanding of how species originate has changed considerably since Darwin's seminal work. One aspect, however, that has been totally ignored is the role that microbes can play in driving plant and animal diversity.

CSIRO, Australia’s national science agency, has outlined how Australia can improve its resilience to future pandemics, reduce their economic impact and protect the community. The  Strengthening Australia’s Pandemic Preparedness  report released, highlights six science and technology areas critical to minimising the impact of pandemics in Australia.

Research measuring the scale of grain and profit lost during harvest has found Western Australian growers have an opportunity to prevent harvest losses which were estimated at $300 million in 2021. Findings from the 12-month Grains Research and Development Corporation (GRDC) investment, led by Grower Group Alliance (GGA), have been compiled from a study conducted across 75 sites during harvest 2021.

Dog owners are being cautioned to keep an eye on their animals this spring to ensure a simple frolic does not end with a trip to the veterinarian. Charles Sturt University academics are leading the country in research that could provide widespread benefits for dog owners and veterinarians across the globe.

The Murdoch University research team - working with local industry including Synergy, Bluewaters Power Station and South32 - investigated the feasibility of using fly ash and other industrial by-products and waste materials as an ingredient in a low carbon concrete product called 'Colliecrete'.

Virginia Gale. On President Beth Gale’s patio we all gathered together for a quick meeting as there wasn’t a lot to report. We were then joined by Skye MacPherson, Project Coordinator for South Eastern Red Tailed Black Cockatoos (Calyptorhynchus banksii) ... The Red Tailed Black Cockatoo are on the endangered list and there are about 1500 in the South East.

A diagnostic tool using nano technology to rapidly detect high-risk plant pests and pathogens in the field will undergo feasibility testing in a biosecurity innovation pilot kicking off this month. The lab-on-a-chip project will investigate if portable nano-biosensors improve the efficiency of plant disease detection at Australian borders and in-field surveillance.

A chlamydia vaccine for koalas could increase the species’ resistance to the potentially fatal disease in a trial in south-west Sydney, which is part of an almost $1.7 million NSW Koala Strategy investment across the region ... “Chlamydia is a serious issue for koalas, leading to blindness, infections and infertility in this precious species. This disease weakens koalas and can make them more susceptible to dog attacks and other threats,”: Minister for Environment James Griffin

Research led by a Charles Sturt University academic examined the innovative ‘SayBananas!’ app that may assist children with speech sound disorders (SSD) and their parents living in less populated areas ... the effectiveness study examined the usability and rating of ‘SayBananas!’, a Mario-style video-game providing high-dose individualised speech therapy with rural Australian children.
