‘It’s over’: five-year hunt for Rambo the feral fox paves way for greater bilby to roam free

Posted on by

Conservationists are confident invasive predator is dead allowing native creatures to flourish again in NSW’s Pilliga Scrub once more

He was the fantastic fox that derailed a multi-million dollar plan to reintroduce endangered native species into one of Australia’s largest forests. But after a five-year hunt that involved 10,400 traps, 3,500 baits, 73 stakeouts, 55 days of scent-tracking dogs and 97 infrared cameras filming 40-hours a week, the red fox nicknamed “Rambo” is officially “no longer”.

It means, for the first time in a century, greater bilbies are running wild in north-west New South Wales.

Carp spawning event fills Murray-Darling flood waters with masses of flailing fish

Posted on by

Experts say while boom in invasive species is not good news for some native fish, there will be winners – including water birds

In creeks, rivers and flood waters across the Murray-Darling Basin, an uncountable and unfathomable number of invasive carp are turning waters into bubbling masses of flapping and flailing fish.

“It’s quite a sight,” said Dr Matt Herring, an environment consultant. “I walked through one of the schools of carp a few days ago and it’s the first time I’ve trodden on fish with every step.”

Feral deer will become Australia’s ‘next rabbit plague’ without a containment zone, experts say

Posted on by

Populations have increased tenfold in the past two decades, leading to a new national strategy to halt the rapid spread

Populations of feral deer have increased tenfold in the past two decades with numbers now too high to be managed by recreational hunting or other recent control measures.

Numbers of the invasive species are now so large in some parts of the east coast that a new national strategy by federal and state governments proposes establishing a “containment zone” to stop the spread of the animals westward across the country.

City commissioner proposes paying per reptile to ramp up efforts to curb numbers of non-native species

A city commissioner in Miami Beach is proposing a novel solution to tackle an invasion of non-native iguanas overwhelming the popular tourist city: paying a bounty for the head of each reptile brought in dead or alive.

Commissioners have agreed to look into the iguana problem and the suggestion by council member Kristen Rosen Gonzalez to offer payments to hunters, which she says would offer an incentive for locals to take an active role.

The Australia-wide rabbit invasion resulted from a single introduction of just 24 animals in 1859, new research has confirmed.

Using historical and genetic data, scientists have pinpointed the origins of what they call “the fastest colonisation rate for an introduced mammal ever recorded”.

Unwanted lockdown goldfish pose a triple threat to native species in UK waterways, study reveals

If that lockdown goldfish is starting to lose its lustre, think twice before throwing it in the river or canal – the creatures may look innocent but their voracious appetite, tolerance for cold and have-a-go habits compared with native species can be catastrophic for local wildlife.

New research shows that goldfish consume much more than comparable fish in UK waters, eat more than other invasive fish and are also much more willing to aggressively take on other competing species.

Delta blues: why estuaries are the canaries in the climate crisis coalmine

These fragile ecosystems are where the impacts of the climate crisis are often felt first, say experts

The Ebro delta appears to be in robust health, to a casual observer. There is water gurgling in the canals and irrigation channels, and what appears to be a mighty river flowing into the sea. The dazzling green rice fields are dotted with ibis, egrets and redshanks.

However, all is not what it seems. The Ebro, the only one of Spain’s three great rivers that flows into the Mediterranean, is one of the most abused and exploited in Europe.

Feral deer in the headlines: Australia’s ‘slow-moving plague’ is finally being noticed

Experts say now’s the time to get on top of the destructive impact of the invasive species on vulnerable ecosystems

If there is one thing beef cattle farmer Ted Rowley has learned while trying to manage feral deer on his property, it is this: for every deer that you see, there are at least another 10 that you can’t see.

“In the beginning you see a few deer and think that’s pretty cute,” he says. “But what you don’t see is the very large number that are across the landscape.”

Spate of firecracker attacks on Taiwan’s invasive iguanas sparks alarm

Rights group calls for action after cash bounty schemes lead to reptiles being blown up and shot with a bow and arrow

A spate of cruelty towards invasive iguanas in Taiwan including stuffing firecrackers in the reptiles’ mouths or shooting them with bows and arrows has prompted animal rights groups to call for a government crackdown.

The Environment & Animal Society of Taiwan (East) said local and provincial government campaigns to encourage community involvement in controlling the spread of introduced species lacked guidelines, resulting in “a chaotic free-for-all at the expense of the welfare of the targeted animals”.

The jade and green peafowl, commonly known as the peacock, has become naturalised in New Zealand after what New Zealand Birds Online calls “benign neglect of birds kept for display”.

Boom time for New Zealand’s rats as lockdown gives them free rein in cities

With pest controllers in lockdown and a population surge last year, the vermin are free to wreak havoc in populated areas, and on native wildlife

Surrounded by ancient rimu trees and the sound of chirping pīwakawaka, Tame Malcolm brings in his second rat of the day from the dense undergrowth of his Auckland backyard. That’s four pests for his tally today – with only a few hundred thousand or so to go.

“It’s the first time my whānau [family] have got to see me doing pest control. I’ve been teaching the whānau that we do this to protect the birds,” says Malcolm, director of Māori-oriented biosecurity business Puna Consultants.

A mystical Malaysian island is grappling with a “sea-borne invasion” of wild boar, which some believe are swimming kilometres across one of the world’s busiest shipping lanes before destroying crops.

“The sea-borne invasion of wild boars leaves us in despair as the animal population is increasing,” said Norhizam Hassan Baktee, chairman of the Malacca agriculture committee, of the influx on the island of Pulau Besar.

Cyprus begins lionfish cull to tackle threat to Mediterranean ecosystem

Voracious fish are bleeding into ocean ‘like a cut artery’, says top marine biologist

Cyprus has held its first organised cull of lionfish after numbers of the invasive species have proliferated in recent years, threatening the Mediterranean ecosystem and posing a venomous danger to humans.

“They’re actually very placid,” said Prof Jason Hall-Spencer, a marine biologist, after spearing 16 of the exotic specimens in the space of 40 minutes in the inaugural “lionfish removal derby” off the island’s southern coast. He added: “The problem is they are not part of the natural ecosystem and we are seeing them in plague proportions.”
