Clarence Valley Independent, 24 March 2021:
They’re
ugly, they’re poisonous, they’re invasive.
And
they’re here, in the Clarence Valley.
Since
their introduction into Australia 86 years ago, the cane toad has
thrived and rapidly expanded its distribution since the first 3000
hopped into the cane fields of North Queensland after being released
by the Bureau of Sugar Experiment Stations in an attempt to control
the native grey-backed cane beetles which were decimating sugarcane
crops and subsequently, impacting the Australian sugar cane industry.
With
no natural predators or diseases which affect their population in the
country, cane toad numbers exploded at an alarming rate and their
presence has had devastating consequences for several native species
including the northern quoll and red-bellied black snake, which often
mistakes the cane toad for native frogs, only to succumb to their
toxins after eating them.
After
the first reports of cane toads in the Clarence Valley made headlines
when the invasive species was discovered in Yamba in 2003, the recent
devastating bushfires around Whiporie and Rappville, north of
Grafton, have resulted in the creation of favourable travel routes
for the ground-dwelling predator.
With
areas of bushland and forestation cleared following the bushfires,
cane toads have hopped their way south along the Summerland Way and
breeched the southern containment line, the Clarence River, within
the past 12 months.
In
late 2020, a new population of cane toads was discovered at
Mountainview, close to Grafton, when local landholders first became
aware
of the recent arrivals after hearing them calling to one another
across the paddocks.
A
report was made to the Department of Primary Industries (DPI) who
alerted local organisation Clarence Landcare to the huge biosecurity
risk on their doorstep.
Clarence
Landcare Educational Officer Kelly McRae, along with coordinator
Debbie Repschlager, attended properties in Mountainview and confirmed
the presence of cane toads, prompting them to take evasive action.
Funded and supported by the New South Wales Government through its
Environmental Trust, the Clarence Cane Toad Education Project in
partnership with the DPI Invasive Species Unit, Clarence Valley
Conservation in Action (CVCIA), Clarence Valley Council (CVC), Yaegl
Traditional Owners Aboriginal Corporation and Office of Environment
and Heritage (OHE) and National Parks and Wildlife Services, aims to
raise community awareness of the invasive species and educate
Clarence Valley residents of the importance of correctly identifying
cane toads and managing their numbers on their properties.
“The number of cane toads is significantly growing in the Clarence Valley,
especially considering the wet weather the area is currently
experiencing, and we want to get the community actively involved so
together, we can help to stop them spreading,” Ms McRae said.
“A
lot of people don’t realise cane toads are in the Clarence Valley.
“We’ve had outbreaks at Brooms Head, Shark Creek and Gulmarrad, and it’s
really important people become aware of them because they pose a huge
biosecurity risk, not only to native animals within the Clarence
Valley, but also to the environment and people’s pets as well.”
Utilising their funding, Clarence Landcare is enabling cane toad controllers to
be on the ground throughout the Clarence Valley, speaking with
community members and liaising with local landholders to encourage
people to do their own cane toad control……..
Describing cane toads as quite easy to catch, Ms McRae recommends people use gloves or place their hand inside a plastic bag when picking up cane toads, therefore avoiding contact with the toxin produced by the bulging glands on their shoulders.
Once caught and secured in the plastic bag, the cane toad can then be placed into the fridge for up to 24 hours before being removed and put into the freezer for 48 hours.
Ms McRae said the cold temperatures lull the cane toads into a sleep state and therefore, they are humanely euthanised before they can be disposed into the red bin.
“It’s important that people ensure they are dead prior to being placed into the bin to reduce the risk of them escaping and subsequently, breeding again,” Ms McRae said.
“Our aim is to stop the cane toads before they damage our local environment and unique ecosystem.
“We all need to work together to prevent them spreading further.”......
