Invasive species

Lee Mead. Over the past 16 years, the Tarrangower Cactus Control Group has achieved remarkable success in increasing knowledge about wheel cactus in our local area, and how to keep the problem under control. Now, in this new era of change, the TCCG Committee has decided to plan some different approaches and objectives for our future.

More than 19,500 feral pigs have been culled in seven months through targeted aerial shooting operations run by the NSW Government ... “There is a definite concern that if FMD was to enter our country, it could be spread through feral pig populations across NSW,”: Minister for Agriculture Dugald Saunders

Holly Fern found at the Lower Road. Holly Fern Cyrtomium falcatum is an exotic introduction to LHI. It is a fast-growing fern that produces high spore load, propagates easily and loves rock face nooks and crannies. It is targeted for eradication on LHI.

The latest State of the Environment Report paints a dire picture for the ongoing survival of Australia’s threatened species under ever increasing pressure from feral animals and weeds ... “Invasive species are the common denominator: foxes and feral cats fuelled by rabbits are the major driver of mammal extinctions while foreign plants are a source of major weed problems impacting landscapes throughout Australia. :Andreas Glanznig, Chief Executive of the Centre for Invasive Species Solutions.

Following the release of the State of the Environment report, the peak national organisation representing over 1,000 forest scientists and professionals in Australia has joined in supporting Federal Environment Minister, Tanya Plibersek’s calls for more reform in the area of environmental law ... “The current approaches to management of Australia’s forests are not working – we believe we need to reform our philosophy of land management, our approach to conservation and how we manage our forests,” Forestry Australia President Bob Gordon.

Lee Mead. A group of 15 tertiary students from Monash University came to the Tarrangower Cactus Control Group field day yesterday, to help us in the war on Wheel Cactus. The event was held in the Maldon Historic Reserve, at the back of the Mount, where they thoroughly enjoyed the natural landscapes and local views.

A recent CSIRO study has found that Australians are more likely to support the use of gene drive technology for feral cat management if there was a perceived problem of invasive species in one’s local neighbourhood ... "Feral cats are an ideal candidate for gene drive research given that their reproductive rates are up to three litters a year, which greatly outpaces conventional measures" : Dr Owain Edwards.

The region’s landscape board is hoping to minimise the feral deer population with the help of a cash injection from the Federal Government. The Limestone Coast Landscape Board (LCLB) has received $344,000 to build on its existing deer control initiatives through the Supporting Communities Manage Pests and Weeds program.

Geoff Helisma. The North Coast LLS’s invasive pests, team leader operations, Dean Chamberlain, said he had not received any recent reports about feral pig sightings in and around Iluka ... “We know from past experience that these pigs are usually moving in and out of the national park, so we work in coordination with the National Parks and Wildlife Service and Clarence Valley Council. However, nothing happens if no one tells us; otherwise, we are just sitting in the dark – we need to know so we can take some action.”

Two localities in the Shire of Gingin have been added to the list of restricted movement zones to contain the spread of European house borer, which is a serious pest of pinewood.

The Morrison Government has released a new five-year Action Plan to underpin the Threatened Species Strategy. This plan aims to coordinate effort for the recovery of 100 priority species and 20 priority places over the next five years with key targets to drive action.

“Sea spurge is now reappearing in NSW, this time in more regional and remote areas of NSW, and we suspect it’s spreading from Victorian and Tasmanian beaches .... A spraying program is underway, using a highly specific biocontrol agent of sea spurge, a fungus, which is native to France" : James Griffin, NSW Environment Minister.

Rockhampton Regional Council is being inundated with reports of Prickly Acacia and Parthenium spreading in the region, and they are calling on the community to assist. Planning and Regulation Councillor Grant Mathers said officers have been working closely with landholders and community stakeholders to establish the extent of the areas of concern, and to treat areas on a priority basis.

This month a lot of cane toads are going to die. That is the purpose of the big Australian cane toad bust happening from January 24-30. Communities across Australia are joining in as organised groups or individually.

Recent catastrophic bushfires and reports of threats to species have highlighted concerns about the management of Australia’s forests. Most prominently, there are increasing concerns that forest management is failing to ensure forest health, build ecosystem resilience and protect threatened species. These concerns are real, but the key drivers are not well understood. A body of opinion and media coverage often presents timber harvesting as the primary threat to forest ecosystems and suggests that creating more national parks will protect threatened species and habitats and reduce the risk of severe bushfires. Yet the situation is far more complex.

New technology developed by the University of South Australia may put an end to predatory cat behaviours in native environments and help control Australia’s feral felines. sing polymer chemistry principles, researchers at UniSA’s Applied Chemistry and Translational Biomaterials Group have created novel Population Protecting Implants (PPIs) to provide a targeted method for controlling invasive and problem feral cats.

Turtle monitoring around Rio Tinto’s Amrun mine has shown the unusual benefit of a mining company that improves the environment around it. Before the Amrun mine was constructed, turtle hatchings were rare in that part of the Cape, mostly because feral pigs predated nests.

Andy Marson and Craig Faulkner are at a property at Bungawalbin searching out feral pigs. They use sweetcorn and molasses to lure the pigs out. “It’s like chocolate for us,” Craig said. As consultants working for ReconEco, an environment consultancy firm based in Lismore, the men are working with the Envite team at Jimmy Malecki’s place, as part of a post-bushfire program to restore the land.

Australia is in the grip of an unprecedented alien attack on its native wildlife and environment, with experts warning more of our unique flora and fauna is in danger of disappearing by 2050 unless urgent action is taken.  

A high-tech underwater drone is helping protect Territory fish and marine life from harmful aquatic pests. The cutting-edge remotely operated underwater vehicle (ROV) takes monitoring to the next level, reducing the need for divers and providing a mobile camera capable of scanning large areas in limited time.

The fire engine red of the coral tree is unmissable at the moment. They are everywhere and are particularly virulent outside Lismore on the Bruxner Highway and along the Richmond River at Coraki and Woodburn. The scarlet flower reflects its bloom into the still river waters and if it wasn’t such an invasive weed, it would be a pretty sight.

Lea Mead. The Cactus Warriors invite you to join us on Sunday 31 October at 10.30am along Mount Back Road where we will be assisting Parks Victoria to remove Wheel Cactus plants from our sensational Maldon Historic Reserve. We’ll be armed with digging hoes and buckets and will concentrate on digging up small wheel cactus plants in an area along Mount Back Road.
