Australian environmental experts are keen to explore a unified approach to combat myrtle rust, in the hope of preventing the devastating disease from spreading
to Western Australia.
The need for a more coordinated response was raised in a recent national workshop coordinated by the TSR Hub in April, amid concerns that previous efforts have been sporadic and ineffective. A working group was established to progress a national plan.
“We believe there are still things we can do to mitigate the impacts of myrtle rust and prevent extinctions,” said Dr Ben Phillips, who leads the Hub’s Project 1.4.
Myrtle rust is an exotic fungal plant disease that entered Australia in 2010 and has since spread rapidly throughout eastern Australia, infecting and killing plants in the Myrtaceae family (eucalypts, tea trees, bottle brushes and paperbarks).
More than 350 plant species are already affected and 30 species are at serious risk of extinction.
“While it’s now almost impossible to rid Australia of myrtle rust, because its spores disperse so easily, our focus is keeping it away from WA (a biodiversity hotspot for native plants) and working to mitigate its impacts,” explained Dr Phillips.
The workshop was attended by leading biosecurity experts from government, research institutions, primary industry groups and conservation parks and led to the establishment of a working group to oversee Australia’s first national myrtle rust protection plan.
Dr Geoff Pegg, Forest Pathologist at the Queensland Department of Agriculture and Fisheries and workshop organiser, is optimistic about the plan.
“I think it’s important for us to take what we have learned from the myrtle rust outbreak and develop better structures for dealing with invasive pests and pathogens in native ecosystems,” said Dr Pegg.
“The working group established in this workshop will form and oversee those structures.”
The group will use its extensive biosecurity experience and incorporate advice from American and New Zealand experts to mitigate the damage caused by myrtle rust and prepare for other potential new disease outbreaks.
Dr Phil Cannon from the United States Department of Agriculture, which has been dealing with the challenges of exotic plant diseases in Hawaii and California, highlighted that a national protection plan will help to keep out many more, and worse, pathogens yet to enter Australia.
Workshop participants toured the Brisbane Botanic Gardens to observe the extensive damage caused by myrtle rust, hearing firsthand accounts from botanists who documented the spread of infection and the vulnerability of certain myrtle species.
The workshop was facilitated by Dr Lucy Sutherland, National Coordinator of the Australian National Botanic Gardens' Australian Seed Bank Partnership.
There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
Pet and feral cats together are killing over two billion reptiles, birds and mammals per year in Australia, and most of these animals are natives, according to a new book written by three of Australia’s leading environmental scientists. The book, "Cats in Australia: Companion and killer", compiles key findings from hundreds of studies and management experience about cats across Australia.
One million species threatened with extinction worldwide. That was the attention-grabbing headline that recently (and, sadly, briefly) captured the world’s attention, when the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystems Services (IPBES) released its first global assessment of how the planet’s biodiversity is faring – and what that means for people.
The Alligator Rivers yellow chat is a small, bright yellow insectivorous bird of the Kakadu floodplains. This Endangered species is imperilled by habitat changes caused by altered fire regimes, buffalo and feral pigs, rising sea levels and the spread of weeds like prickly mimosa and introduced grasses. What has been happening to degrade these floodplains has been equally of concern to Traditional Owners as to yellow chat researchers.
The central purpose of the Threatened Species Recovery Hub is delivering research that is relevant for and useable by decision-makers, land managers and others responsible for recovering threatened species. Working with partners is vital if we’re to achieve this.
