Invasive worms are spreading across Oregon, threatening gardens and forests | Oregon Field Guide
CW: It can be fraught talking about introduced species that create ecosystem imbalances since there's a history of metaphorical pest rhetoric being used by eugenicists in the US; the worm species comes from East Asia so there are references to that.

Coogee WA park has fruiting olive trees being used as food by (I think) parrots.
It's been a mystery to me why so many olives get left on the tree or on the ground uneaten by birds.
This is the first time I've seen evidence of them being eaten.
If they are good food then if a species taps into this source its population might boom.
Hoping it's 28s / ring-neck parrots. And not the invasive Eastern Rosellas.

A bit of hopeful environmental news: In Kosciuszko National Park, the reduction of thousands of feral horses has allowed fragile alpine ecosystems to begin recovering. Native plants are returning, wetlands are healing, and wildlife habitats are slowly being restored.
It's a meaningful reminder that with careful management and respect for balance, nature can regenerate. Good news for biodiversity and for future generations.

The two brown-grey fallow deer does here look like they’re about ready to drop fawns. It’s that time of the year.
They don’t belong here, as they’re introduced (nearly 200 years ago), but they’re here now, so managing them becomes a priority.

Man's best friend - First eradicate the Neanderthals, then biodiversity
Humans and their dogs drove our evolutionary cousins Neanderthals to extinction
"Early dogs, bred from wolves, played a critical role in the modern human’s takeover of Europe 40,000 years ago when we vanquished the Neanderthal locals. The Neanderthals, who had lived there for more than 200,000 years. However, within a few thousand years of our arrival, they disappeared...Humans and hunting dogs were, and still are, a deadly combination." >>

Australia is “riding on the dog's back"
Pastoralism gone to the dogs
A "study estimated the nation's 270,000 working livestock dogs contributed to the economy at an amount similar to Australia's beef exports to the US in 2023-24. Roughly $800 million is what is being saved in labour by the sector by having dogs there rather than having people."

Merlin called them Red Junglefowl. iNaturalist called them Domestic Chicken. The bird didn't change — just the taxonomy each platform was willing to accept.
Many pet owners move to the country just so their dogs can roam in wildlife habitat
"We moved to the country to give our rescued working dogs a better life."
74% of Australians own introduced species as pets.

Reversing Australia’s trajectory of biodiversity decline
"Australia has ... lost at least 100 species since European colonisation."
"To undo all the human-induced damage and bring nature roaring back across their viable continental range would come with a staggering cost – A$583 billion per year, every year, for at least 30 years. That’s 25% of our GDP. "
"The most cost-effective action is to avoid further damage."

The roaming cats of Bellingen are one of the biggest threats to wildlife
"The average pet cat kills 110 native animals each year, roughly 320 million across Australia, and that doesn’t even include frogs or insects. The species is directly responsible for the third highest number of extinctions in Australia, after humans and chytrid fungus."
Victoria has " effective legislation that’s empowering local government to take action on the issue of roaming pet cats."

Those lists represent four vectors of change.
Massive #loss of #songbirds and #insects (VERY bad).
Recovery of #raptors from DDT (wonderful - the only birds of prey I saw at the Naze in the seventies were a family of #kestrels).
Arrival of new species under #ClimateChange (natural, but a sign of bad things).
Arrival of #IntroducedSpecies (not good).
This one is really fascinating. Involving a chain of events that includes humans, ants, lions, elephants, buffalo and acacia trees.

Kangaroo trying to fend off a pack of pet dogs
It is an exception that pet owners have their dog on a leash in Australia. They are allowed to roam in the bush and hunt local wildlife. When witnessed, the owner pretends to control their dog/s by yelling and screaming. Meanwhile ( as shown in the video) the native wildlife have to fend for their life. (video)

The rate of pet-related injuries increased over the past decade across all Australian regions
"Australians are around 90 per cent more likely to be attacked by a dog than by a venomous snake or lizard. Approximately 40 per cent of Australian households have a dog, equating to about 5.1 million dogs. Children under five years continue to be at higher risk of injuries to the head and neck than any other age group."

And then the koalas just vanished...
Speeding cars, road designs, roaming dogs and disease are the biggest koala killers.
Logging and sprawl should also be added to the list of extinction makers
"A database tracking hospital admissions and deaths reveals the devastating impact cars, disease and dogs are having on the South East Queensland koala population"
.
"In the five years between 2009 and 2014, 52% of reported wild koala deaths were caused by car strike, 34% were from a chlamydia-related disease and 14% were because of a dog attack.
"This equates to 1,431 koala deaths from a car strike, 943 chlamydia-related deaths, and 395 dog attack deaths in just five years."
"Remember that these deaths were just the reported cases, so the real numbers would be significantly higher."
