Australia Releases THE LARGEST CARNIVOROUS MARSUPIAL – What Happened Next To Feral Cats

On the tenth of September in the year two thousand and twenty, a profound and heavy silence settled over the rugged, ancient landscape of the Barrington Tops sanctuary in New South Wales.

Behind a tightly secured, meticulously engineered barrier of reinforced wire and metal, a dedicated team of conservation experts watched with bated breath, their hearts pounding with nervous anticipation.

Heavy metal crates, custom-built to ensure the utmost safety during transport, had just been carefully unloaded from the back of specialized conservation vehicles and placed gently upon the forest floor.

The crisp, cool mountain air of eastern Australia carried the familiar scent of eucalyptus and damp, rich earth, a scent that had been missing a crucial biological element for millennia.

With a sudden, sharp metallic clatter that echoed through the quiet groves of towering trees, the heavy latches of the transport crates were finally thrown open by the waiting conservationists.

The reinforced doors swung wide, revealing the dark, shadowed interiors of the boxes, and two stout, muscular marsupials tentatively stepped out into the dappled afternoon sunlight.

These two animals, affectionately named Lenny and Lisa by the devoted staff who had painstakingly raised them, represented far more than just a successful captive breeding program.

For the very first time in roughly three thousand years, wild Tasmanian devils had firmly set their padded paws upon the soil of mainland Australia, reclaiming a birthright that had long been lost to history.

They did not rush immediately into the dense undergrowth, but instead stood remarkably still for a long, poignant moment, as if trying to process the magnitude of the world around them.

Their dark, wet noses twitched rapidly as they took in the complex, unfamiliar scents of a wild, sprawling landscape that their ancient ancestors had once fiercely ruled as apex scavengers.

Renowned Hollywood actor Chris Hemsworth, alongside his wife Elsa Pataky, stood quietly in the background, offering their hands and their global platform to assist the team in releasing the remaining animals.

The newly freed devils hesitated for just a few seconds more, their dark, expressive eyes carefully scanning the towering timber and the dense, green ferns that blanketed the sanctuary floor.

Then, fueled by deeply ingrained, ancient instincts that had survived thousands of years of exile, they quickly dashed into the thick bushes and completely disappeared from human sight.

Watching the animals vanish into the shadows from a short distance behind, Tim Faulkner, the visionary president of Aussie Ark, felt a surge of indescribable emotion and profound triumph.

He turned to the gathered crowd of scientists, supporters, and media, and with a voice full of unwavering conviction, confidently declared the ultimate vision of their ambitious project.

He proclaimed that in one hundred years, future generations would witness these incredible animals complete their vital mission of restoring the broken ecology of an entire country.

But as the days and months unfolded, the conservation team would soon discover that they did not actually have to wait nearly a century to see the dramatic impacts of their bold experiment.

In every specific area where the newly released Tasmanian devils successfully established their territory, the devastating presence of introduced, invasive species began to quietly and completely disappear.

Then, roughly six months after that historic release day, something incredibly strange and entirely unexpected appeared on the sanctuary’s sophisticated monitoring equipment.

A hidden, motion-activated camera mounted securely to the rough bark of a towering chestnut tree captured a mysterious scene that the experts initially struggled to comprehend or fully explain.

The grainy, black-and-white infrared footage left the seasoned biologists scratching their heads, wondering why that particular creature was wandering through this specific part of the forest.

And more importantly, they began to ask themselves how a conservation project centered entirely on saving the Tasmanian devil could inadvertently end up solving three of Australia’s most difficult ecological problems.

To truly understand the gravity of this situation and the sheer magnitude of what was happening at Barrington Tops, one must first look back deeply into the ancient history of the Australian continent.

When the massive landmass of Australia was still largely an untouched, pristine wilderness, Tasmanian devils were incredibly common and dominant carnivores spread across the entire continent.

Their distinctive, chilling screeches and heavy footfalls could be heard echoing from the arid, unforgiving deserts of central Australia to the lush, vibrant tropical rainforests of the deep north.

They were equally at home in the cool, temperate woodlands of the south, adapting remarkably well to almost every climate and geography the massive island continent had to offer.

For millions of years, these robust, fearless marsupials served an absolutely critical role as the premier top scavengers and highly effective mid-size predators across most of the continent’s major ecosystems.

They were nature’s indispensable cleanup crew, consuming the carcasses of fallen animals, preventing the spread of diseases, and maintaining a delicate, ancient balance within the food web.

But their later, abrupt disappearance from the mainland remained a baffling, frustrating mystery that dedicated scientists, paleontologists, and historians debated passionately for many years.

Various theories were proposed, ranging from sudden, catastrophic climate shifts and prolonged, devastating droughts to the potential impacts of early human expansion and hunting practices.

It was not until a comprehensive, groundbreaking study was published in two thousand and eighteen that researchers finally concluded exactly why these resilient animals had vanished from the mainland.

The extensive research definitively proved that they had been wiped out roughly three thousand two hundred years ago directly because of the arrival and rapid proliferation of dingoes.

Dingoes, which were introduced to the continent by seafaring people from the north, were roughly three times larger than the native devils and possessed a completely different evolutionary strategy.

Crucially, dingoes were highly social canines that hunted efficiently in organized, strategic packs, giving them a massive, insurmountable advantage over the fiercely solitary and independent Tasmanian devils.

Whenever a solitary devil attempted to defend a carcass or protect its territory, it simply could not withstand the coordinated, relentless attacks of a highly organized pack of wild dogs.

Over the course of a few brutal centuries, the relentless competition for dwindling food resources and the direct predation by dingoes caused the Tasmanian devils to slowly disappear from the mainland.

Fortunately, by a stroke of geographical luck, the dingoes never managed to cross the treacherous, stormy waters of the Bass Strait to reach the isolated, southern island of Tasmania.

This geographical barrier made the rugged, untamed island of Tasmania the very last remaining refuge on Earth for the embattled species, allowing them to thrive in isolation for thousands of years.

In the dense, dark forests of Tasmania, the devils faced no competition from wild dogs, returning to their rightful place as the undisputed apex scavengers of their unique, island ecosystem.

But unfortunately, even the remote, pristine wilderness of Tasmania would not remain a safe, untouched haven for these remarkable marsupials forever.

In the fateful year of nineteen ninety-six, a wildlife photographer captured images of devils with horrific, grotesque lumps on their faces, prompting scientists to investigate a terrifying new biological threat.

Researchers soon documented the devastating emergence of Devil Facial Tumor Disease, an incredibly aggressive, wildly mutating, and extremely rare form of naturally occurring contagious cancer.

Unlike almost all other cancers known to modern science, this specific disease was not caused by genetics or environmental toxins, but was directly transmitted from one living animal to another.

Tasmanian devils have a famously aggressive, highly confrontational social structure, often engaging in fierce, bloody battles while fighting over food, securing mating rights, or competing for territory.

During these intense, chaotic scuffles, the animals frequently bite one another on the face and neck, inadvertently allowing living, microscopic cancer cells to pass directly through their open, bleeding wounds.

Because the island population of devils had suffered from a lack of genetic diversity, their immune systems completely failed to recognize the invading tumor cells as a dangerous, foreign threat.

As the vicious tumors take root and aggressively grow, they can completely deform the animal’s jawbone, slowly pushing their teeth out of alignment and destroying their facial structure.

This agonizing deformation makes eating solid food increasingly difficult, excruciatingly painful, and eventually completely impossible, leaving the infected animal far too weak and emaciated to survive.

Within just a few short, tragic decades following the disease’s discovery, the wild population of Tasmanian devils plummeted drastically, suffering a catastrophic decline of around ninety percent.

The once-ubiquitous calls of the devils faded from the Tasmanian night, and the species was rapidly pushed toward the very brink of complete, irreversible biological extinction.

And yet, this very same species, battered by disease and struggling for sheer survival, would later achieve something absolutely remarkable on the mainland, helping humans repair terrible ecological damage.

But to truly understand why the return of the devil matters so much, you first need to understand the fragile, intricate mechanics of how a natural ecosystem functions and collapses.

When a highly important prey species or a dominant predator completely disappears from an established food web, a massive, highly dangerous ecological gap can quickly and violently emerge.

In the case of the Australian mainland, the sudden absence of the Tasmanian devil created a massive, glaring vacancy for a mid-sized predator that could hunt small game and aggressively scavenge.

And the highly opportunistic, highly lethal animal that rapidly took advantage of that newly created ecological gap was none other than the fiercely adaptable feral cat.

It is a well-documented historical fact that cats are not native to the Australian continent and played no part in its millions of years of isolated evolutionary history.

They were initially introduced by early European colonists and sailors on the First Fleet, brought deliberately on ships to aggressively control exploding populations of invasive rats and mice.

Over the ensuing decades, many of these highly capable feline hunters inevitably escaped from colonial settlements, wandering deep into the wild, unmapped bushland of their new home.

Free from the natural predators and diseases of their native lands, they rapidly multiplied and eventually spread their devastating presence across nearly the entire vast, sprawling continent.

Feral cats are masters of stealth and survival, incredibly adapted to the harsh Australian climate, obtaining all the moisture they need directly from the fresh blood and tissue of their prey.

During the blistering heat of the long Australian day, they sleep deeply and hide out of sight beneath dense, prickly shrubs, squeezed between large rocks, or safely tucked inside hollow, fallen logs.

But once the harsh sun finally sets and the cool, enveloping darkness falls over the landscape, their glowing eyes open, and the relentless, silent hunt officially begins.

A small, unsuspecting native lizard moving ever so slightly beneath a pile of dry leaves, a ground-nesting bird sitting on its fragile eggs, or a tiny marsupial weighing only a few hundred grams all become instant targets.

These native creatures evolved for millions of years in complete isolation without feline predators, meaning they completely lack the natural instincts and evolutionary adaptations required to recognize or evade a stalking cat.

Every single year, biologists and environmental researchers estimate that millions of feral cats brutally kill anywhere from one to two billion native reptiles, birds, and small mammals across Australia.

This staggering, almost incomprehensible daily slaughter has pushed dozens of unique, irreplaceable native species to the absolute brink of total extinction, fundamentally altering the landscape.

In desperate response, the Australian government has utilized an arsenal of traps, toxic poison baits, targeted hunting campaigns, and massive, costly exclusion fencing to try and artificially control the feline population.

But despite spending millions of dollars and employing thousands of dedicated workers, the sheer scale of the feral cat problem remains overwhelmingly massive and extremely difficult to effectively solve.

Then, amidst the despair of the ongoing extinction crisis, scientists working deep in the remaining healthy forests of Tasmania discovered a sudden, highly unexpected, and incredibly vital ecological clue.

The researchers strategically placed dozens of motion-sensing cameras in pristine areas where healthy Tasmanian devils were still highly abundant and actively patrolling their natural territories.

They then painstakingly compared that footage with visual data gathered from separate locations where the horrific Devil Facial Tumor Disease had already caused local devil populations to decline sharply.

When the massive amounts of data were finally analyzed, the shocking results clearly showed that in areas with fewer active devils, nocturnal feral cat activity was staggeringly higher, by about fifty-eight percent.

This incredible revelation immediately sparked intense debate among the scientific community regarding the complex, hidden relationships between the two completely different species of predators.

So, the researchers began to ask, did this definitive data actually mean that the native Tasmanian devils had somehow naturally solved Australia’s seemingly impossible feral cat problem?

And if this hypothesis was indeed entirely true, how exactly did a relatively slow-moving, heavily built marsupial scavenger manage to suppress a highly agile, incredibly lethal feline hunter?

As it turned out, the ecological mechanism was not quite as simple as the devils directly hunting, killing, and eating the invasive cats, though physical altercations certainly did occur.

The ultimate, fascinating answer was far more complicated, rooted deeply in the complex psychology of survival and the ecology of fear, but we will explore those specific mechanics a little later.

Because unfortunately, highly adaptable feral cats are not the only devastating invasive predators causing incredibly serious, widespread ecological problems for the Australian wilderness.

Beginning in the middle of the nineteenth century, wealthy European colonists deliberately and recklessly introduced the red fox to the Australian landscape purely for the purpose of traditional recreational hunting.

They wanted to recreate the familiar, aristocratic sports of their distant homeland, completely ignoring the potential, long-term consequences of releasing a highly intelligent, rapidly breeding carnivore into a naive ecosystem.

Within just a few short decades of their initial release, the incredibly adaptable, reddish-furred foxes had exploded in numbers and could be easily found thriving across massive stretches of the country.

They established dense populations across rolling grasslands, tough, semi-arid shrublands, and devastatingly, along the vulnerable, porous edges of designated national parks and protected nature areas.

Much like the feral cats, these highly intelligent foxes wait patiently for the oppressive heat of the day to pass before emerging from their underground dens to aggressively patrol the night.

After dark, a native, long-nosed bandicoot cautiously emerging from its protective burrow, or a tiny, bouncing bettong frantically digging through the soil for nutritious fungi, are in grave danger.

A small marsupial weighing only a few hundred grams might suddenly hear the terrifying, faint sound of dry leaves rustling sharply just a few feet behind it in the darkness.

But tragically, because many of these small native species had never evolved alongside canine predators like foxes, their natural, hardwired neurological reactions were often far too slow and completely inadequate.

Instead of immediately fleeing into the safety of deep cover, they might instinctively freeze in place, run wildly in the wrong direction, or simply fail entirely to recognize the severe danger rushing rapidly toward them.

Even more troubling to wildlife experts is the fact that these introduced foxes do not always kill only to satisfy their immediate biological need for food.

Through a brutal, highly destructive instinctual behavior officially known to biologists as surplus killing, a single, energized fox may aggressively attack and kill multiple native animals in rapid succession.

Driven by a hardwired predatory reflex triggered by the panic and movement of naive prey, the fox will slaughter far more than it can consume, leaving behind a trail of uneaten, wasted carcasses.

As more and more compelling scientific evidence strongly suggested that the historical disappearance of native predators had effectively opened the door for cats and foxes to relentlessly spread, a radical idea emerged.

Visionary scientists and bold conservationists began seriously considering the unprecedented, massive undertaking of actively returning a missing native predator to the heavily damaged ecosystem.

At first glance, the most obvious and immediate choice for this crucial apex role seemed to be the native dingo, which was already well-adapted to the harsh mainland environment.

Across many remote, northern and central parts of Australia where wild dingoes are still present in large, healthy numbers, ecological studies show they can indeed put significant natural pressure on smaller predators.

Their large size, aggressive pack mentality, and territorial dominance make them highly effective at hunting down and driving away invasive mesopredators such as red foxes and feral cats.

So, logical environmentalists naturally began to ask, why not simply introduce strict laws to protect existing dingo populations or artificially restore their numbers across the southern parts of the continent?

The massive, seemingly insurmountable problem with this seemingly simple plan begins immediately just beyond the fragile wire boundary of the nearest rural farm fence.

Dingoes are highly capable, incredibly strong canines that are easily large enough to brutally attack and kill valuable sheep, newborn calves, and other vulnerable, vital agricultural livestock.

This harsh reality means that any government-backed plan to actively protect or purposefully expand their wild populations would immediately and violently come into direct conflict with the powerful, wealthy livestock industry.

A purely ecological solution intended to save native wildlife could very quickly and dangerously turn into a bitter, highly political struggle between passionate conservationists and desperate farmers trying to protect their livelihoods.

Understanding this difficult political reality, scientists quickly realized they desperately needed to find another, more suitable predator to fill the massive ecological void.

They required a native animal that was fiercely strong enough to naturally compete with invasive cats and foxes, but importantly, small enough that it would be far less likely to put pressure on heavy livestock.

As they scoured the historical records and biological profiles of native fauna, the rugged, tenacious Tasmanian devil gradually emerged as the absolute, unique, and perfect biological candidate.

But before anyone could seriously, practically consider the monumental task of returning them to the vast, open wild of the mainland, the species itself had to be rescued from the brink of total annihilation.

Tim Faulkner, alongside the incredibly dedicated staff at Aussie Ark, recognized that they first had to comprehensively save the species itself from completely disappearing due to the relentless facial cancer.

Beginning in the year two thousand and eleven, they took the ambitious, highly stressful step of starting to carefully build a robust, genetically diverse insurance population right on mainland Australia.

This critical population was strictly isolated by thousands of miles of ocean from the horrific, raging outbreak of the deadly Devil Facial Tumor Disease currently devastating the island of Tasmania.

Over the course of nearly a decade of tireless, around-the-clock work and immense dedication, more than three hundred and ninety healthy devils were successfully born and raised within the program.

And by the critical target year of two thousand and twenty, the expanding conservation program was actively and successfully caring for a thriving population of more than two hundred energetic animals.

Behind massive, incredibly secure protective fences, the dedicated, passionate staff tried their absolute hardest to keep the captive devils as wild and natural as biologically possible.

They strictly minimized human contact, forcing the animals to rely on their own instincts by finding their own hidden food, fiercely competing with one another over large bone-in carcasses, and aggressively digging their own complex dens.

They were purposefully encouraged to engage in completely natural, rough interactions with other devils, ensuring they retained the vital social and survival skills their wild ancestors had relied upon for millennia.

But Tim Faulkner, driven by a grand, sweeping vision of a fully restored Australian continent, absolutely did not want these magnificent creatures to simply spend their entire, precious lives entirely inside safe conservation enclosures.

He knew deep down that if Tasmanian devils really possessed the unique capability to aggressively compete with invasive cats and foxes, the next logical, essential step had to be returning them to a real, functioning ecosystem.

The bold, unprecedented idea certainly sounded incredibly promising on paper, but it was highly controversial, and unfortunately, not every respected scientist in the tight-knit biological community fully agreed with the plan.

Immediately after a detailed, formal proposal was publicly submitted to reintroduce the devils to mainland Australia in two thousand and fifteen, a prominent, highly vocal research team issued a stark warning.

They publicly cautioned that introducing the species into a completely altered environment could act as little more than a blunt, unpredictable instrument, causing far more ecological damage than it actually solved.

They correctly pointed out that hard, empirical data on the complex, nuanced interactions between these specific, highly territorial predators were still incredibly limited and largely theoretical.

The skeptical scientists argued fiercely that Tasmanian devils were absolutely not simply smaller, less lethal versions of dingoes, and they possessed entirely different foraging, hunting, and territorial behaviors.

They passionately warned that artificially introducing a formidable predator into a completely new, modern landscape could rapidly create unforeseen, disastrous consequences that even the most advanced computer models could not accurately predict.

Both sides of this intense, highly publicized scientific debate had a very valid, incredibly well-reasoned point, reflecting the immense difficulty of actively managing fragile natural environments.

One side clearly saw a golden, fleeting opportunity to restore a deeply broken ecosystem and rapidly save dozens of native prey species from the very real threat of imminent extinction.

The other side saw the terrifying, very real risk of inadvertently creating an entirely new, highly destructive problem by recklessly meddling with an environment that had already been altered beyond recognition.

So, as the intense debates raged on in academic journals and environmental conferences, the ultimate question remained: who was actually right about the future of the Tasmanian devil?

That highly complex answer may ultimately depend entirely on how you choose to see the philosophy of conservation and the role of human intervention in repairing the natural world.

But in Australia, a nation currently suffering from the highest mammal extinction rate on the entire planet, they ultimately decided that the immense potential benefits simply outweighed the terrifying risks, and they boldly decided to release them.

However, long before any transport crate could be unlatched or any animal could taste freedom, the tireless team at Aussie Ark first had to build a place large enough to safely hold them.

They needed to construct a massive, highly complex environment where the newly relocated Tasmanian devils could live entirely on their own, completely free from the dangers of roads, without depending on humans for survival.

Deep in the lush, mountainous Barrington Tops region of New South Wales, an area renowned for its ancient, towering trees and crisp, cool climate, they undertook a monumental engineering challenge.

They successfully enclosed a staggering four hundred hectares of pristine, natural forest and carefully surrounded the entire, sprawling area with a highly advanced, utterly impenetrable predator-proof fence.

This massive, meticulously constructed fence was specifically designed with deep skirts buried into the earth to prevent foxes from digging underneath, and curved overhangs to stop feral cats from climbing over the top.

Inside this massive, secure perimeter, the landscape was still a true, unforgiving wilderness, complete with towering eucalyptus trees, natural rock shelters, flowing streams, and abundant, wild food sources.

This rugged, demanding environment actively forced the newly relocated devils to rely completely on their ancient instincts to forage for themselves, find secure dens, and aggressively establish their own complex territories.

After years of relentless, backbreaking labor and massive fundraising efforts, in November of two thousand and nineteen, the incredible, sprawling fence was finally and completely finished.

Immediately following the construction, specialized tracking teams worked tirelessly to ensure that every single feral cat and red fox trapped inside the newly created sanctuary was safely and humanely removed.

This massive, critical clearing effort officially turned the protected 400-hectare area into a highly unique, deeply vital transition zone between pampered captive conservation and true, brutal life in the wild.

But the specific twenty-six individual devils carefully chosen for the highly publicized, historic release project were absolutely not selected at random or by mere convenience.

They came directly from Aussie Ark’s highly successful, genetically diverse mainland insurance population that we discussed in detail earlier in this story.

In the crucial months leading up to the release, expert geneticists and highly trained biologists sat for hours in front of complex, highly detailed pedigree charts and genetic sequencing data.

They meticulously matched individual names, tracking numbers, and ancient bloodlines to perfectly select a diverse group of animals that was physically healthy, behaviorally robust, and incredibly genetically diverse.

Their primary, overriding goal was to carefully curate a founder population that carried as absolutely little risk of dangerous, long-term genetic inbreeding as biologically possible.

But perhaps even more importantly than their pristine DNA, these specific twenty-six devils had been purposefully raised in a highly specific, hands-off way that intentionally preserved as many of their wild instincts as possible.

From the moment they were young joeys, they were actively forced to compete fiercely for their food, search for their own natural shelter in the rain, and navigate complex social interactions with other aggressive devils.

The dedicated staff ensured they grew up learning how to survive a harsh landscape, rather than living completely dependent on the easy, predictable care of human zookeepers.

To ensure the safety of the precious animals, the ambitious project was carefully divided into stages, and first, a small, highly monitored group of just fifteen devils was released into the sanctuary as a crucial trial run.

Advanced GPS signals and VHF tracking pings from their fitted radio collars quickly and clearly showed that the animals began rapidly spreading out, bravely exploring the complex, hilly terrain.

The vital tracking data proved beyond a doubt that they were successfully hunting, scavenging, finding water, and seamlessly adapting to the dense, unfamiliar forest environment without any human assistance.

Only after that incredibly brave first group firmly passed the ultimate survival test with flying colors did the conservation team finally give the green light to move the master plan to the highly anticipated next stage.

On that historic morning of the tenth of September two thousand and twenty, eleven more heavy, securely locked crates were carefully brought deep into the heart of the Barrington Tops sanctuary.

The globally famous actor Chris Hemsworth, his dedicated wife Elsa Pataky, and the incredibly emotional, exhausted conservation team stood closely nearby in the dappled forest light as each heavy metal latch was finally opened.

Lisa, Lenny, and the remaining magnificent devils stepped cautiously out of their dark boxes, deeply sniffed the dry, fragrant eucalyptus leaves beneath their padded feet, and one by one, disappeared completely among the ancient trees.

With that incredibly brief, highly emotional moment, a total of twenty-six wild Tasmanian devils had finally and officially returned to the mainland of Australia after a devastating absence of roughly three thousand years.

And the very moment the striped tail of the last devil disappeared from view into the thick, green undergrowth, the fundamental, daily role of the human caretakers permanently and dramatically changed as well.

There would be absolutely no more easy, pre-butchered meals carefully placed in front of them, and there would be no more gentle, guiding hands directing them towards warm, dry shelter when the cold rains came.

Instead, the only connection between the humans and the animals would be the advanced radio collars that quietly and relentlessly transmitted locational signals from deep inside the dark, unforgiving forest.

Meanwhile, dozens of camouflaged, highly sensitive motion-activated camera traps waited silently, strapped to tree trunks, patiently waiting for the nocturnal predators to eventually pass through the darkness.

From that monumental, historic point forward, the anxious researchers could only stand nervously on the outside of the massive fence, patiently watching the complex data roll in on their computer screens.

The newly wild devils had to completely rely on themselves to successfully find their own food, carefully choose their own safe dens, aggressively establish their own sprawling home ranges, and eventually find healthy mates entirely on their own.

But if those incredibly brave twenty-six Tasmanian devils had indeed survived the harsh transition, and had truly begun adapting to the rugged mainland ecosystem, what exactly happened next?

What incredible, highly unexpected event occurred during their very first, highly stressful year in the wild that truly stunned the seasoned conservation team and made international headlines?

We are finally getting to the most beautiful, highly anticipated part of this incredible, ongoing biological narrative right now.

In the cool, crisp autumn month of May two thousand and twenty-one, the dedicated Aussie Ark team cautiously entered the dense sanctuary to carry out a highly important, strictly routine health check on the female devils.

Using specially designed, highly safe trapping mechanisms, each incredibly elusive animal was briefly and carefully recaptured so the trained veterinary staff could thoroughly examine its physical health.

The highly experienced veterinarians checked their teeth for wear, examined their thick fur for parasites, weighed them to ensure they were finding enough food, and most importantly, prepared to gently inspect the marsupial pouch on their bellies.

When a highly focused staff member gently and carefully opened the warm, backward-facing pouch of the very first recaptured female, what they found hidden inside was absolutely not a dangerous injury or a tragic sign of weakness.

Tucked safely inside the warm, dark folds of the mother’s skin, firmly attached to a life-giving teat, was a tiny, incredibly fragile, perfectly formed pink joey.

Overcome with a wave of sheer disbelief and immense joy, the veterinary team quickly and carefully moved to check the pouch of the second captured female devil, finding yet another perfectly healthy, growing joey.

By the end of the long, highly emotional day of medical inspections, the exhausted but ecstatic team had officially confirmed that at least seven brand-new, healthy Tasmanian devil joeys had been born.

Crucially, these precious new lives had been conceived and born entirely inside the wild, rugged expanse of the Barrington Tops Wildlife Sanctuary, not inside a controlled, sterile captive breeding facility.

They were not born beneath the comforting, artificial glow of warming lamps in a high-tech veterinary clinic, and they certainly did not arrive with anxious humans standing closely nearby to assist or monitor the delicate breeding process.

The tiny, blind, completely hairless joeys had been naturally conceived, safely born, and were now rapidly growing up entirely in the harsh, unforgiving bush of Barrington Tops.

Their fiercely independent, incredibly resilient mothers had successfully found their own secure shelter, aggressively hunted for their own food, successfully courted wild mates, and become pregnant completely on their own.

They had accomplished this incredible biological feat inside the very same ancient forest where their unique, keystone species had been entirely absent from mainland Australia for roughly three thousand long years.

That unprecedented, deeply historic level of complete, unassisted biological independence was exactly what made the astonishing result of the health checks so incredibly remarkable to scientists around the world.

Because long before they could even think about successfully reproducing and raising fragile young, those twenty-six pioneer devils first had to fundamentally relearn almost every single complex part of life in the wild.

They had to learn exactly which animal trails were safe to travel, exactly where reliable food and water sources could be found in a drought, and exactly which rocky dens could provide the best shelter during the scorching heat of the day.

They had to navigate incredibly complex, highly aggressive social structures, figuring out exactly where the invisible, fiercely guarded territories of other adult devils began and ended to avoid fatal conflicts.

Yet, despite all of these massive, seemingly insurmountable ecological and behavioral challenges, in their very first, highly stressful wild breeding season, a brand-new, self-sustaining population had already naturally begun to form.

Over the next few months, hidden infrared cameras strapped to the ancient trees unexpectedly captured incredibly touching footage of a fully grown mother devil moving slowly and carefully through the darkness with heavy, swollen teats.

The massive amounts of tracking data showed that some independent individuals chose to travel completely alone among the towering eucalyptus trees, while the expansive home ranges of others naturally and peacefully began to overlap.

Exactly two years after the historic release, the silent, ever-watchful camera traps captured another incredibly remarkable, deeply emotional moment that touched the hearts of everyone involved in the project.

Two adult female sisters, who had been completely separated during the chaotic logistics of the initial reintroduction phase, miraculously appeared together in the very same small, rocky area of the vast forest again.

They were absolutely no longer captive, dependent animals simply being monitored and cared for by anxious human zookeepers; they were wild, completely self-sufficient predators thriving in their ancestral home.

They were independently choosing exactly how to efficiently use the massive, complex landscape, expertly moving through the thick undergrowth, and successfully living exactly like a wild, ancient population should.

Now, with the species successfully established in the sanctuary, let us finally return to the most important, highly complex ecological question central to this entire, sweeping scientific story.

Why exactly does the physical presence of relatively slow, heavily built Tasmanian devils inherently reduce the massive numbers of highly lethal cats and foxes without the devils actually needing to hunt and eat them?

The incredible, highly effective answer to this complex biological mystery is beautifully simple, yet deeply rooted in millions of years of evolutionary psychology and survival instincts.

The robust, stocky Tasmanian devil is officially classified as the largest surviving carnivorous marsupial on the entire planet, but it is absolutely not a highly agile predator that specializes in rapidly chasing down fleeing prey.

Instead, nature has perfectly designed it to be an incredibly efficient, highly aggressive, and utterly dominant scavenger, equipped with one of the strongest bite forces of any mammal its size.

A large, heavy kangaroo carcass tragically lying beside a rural dirt road, or a wild animal that naturally died deep in the impenetrable bush, provides a massive, vital feast for a hungry devil.

With their incredibly powerful, bone-crushing jaws, even the toughest, leathery skin, stringy organs, and dense, thick bones can all be easily consumed and digested by an adult devil, leaving absolutely nothing behind.

And that incredible, unmatched scavenging efficiency immediately creates very real, incredibly intense biological competition with the highly invasive, completely unwelcome feral cats and red foxes.

Imagine a highly realistic, incredibly common scenario: a large native kangaroo has just naturally died from old age somewhere deep in the quiet, shadowed undergrowth of an Australian forest.

The pungent, unmistakable smell of decaying meat quickly drifts through the dense trees and immediately attracts a hungry, highly opportunistic feral cat searching for an easy, completely effortless meal.

But just before the cautious, stealthy cat can sink its sharp teeth in and drag away a prime piece of meat, a massive, heavily muscled Tasmanian devil suddenly appears out of the surrounding darkness.

The devil is significantly larger, immensely stronger, and aggressively begins making its terrifying, characteristic guttural growls and ear-piercing screeches to assert immediate, violent dominance over the area.

It fearlessly moves in, baring its massive, bone-crushing teeth, completely prepared to violently fight and compete for exclusive access to the highly valuable, nutrient-rich carcass.

For a highly cautious, solitary hunter like a feral cat, whose entire survival depends on entirely avoiding severe physical injury, that terrifying confrontation may simply not be worth the massive, life-threatening risk.

A single, powerful bite from a raging devil could easily crush a cat’s delicate leg bone, completely crippling the feline and guaranteeing a slow, agonizing death from eventual starvation in the wild.

If easier, far less dangerous food can simply be found by hunting smaller prey somewhere else in the forest, why on earth would the cat risk its life to fight a Tasmanian devil for a dead kangaroo?

As a direct, incredibly powerful result of this dynamic, the regular, intimidating physical presence of devils in an area naturally causes intelligent cats to fundamentally change exactly when and how they boldly forage for food.

They are essentially forced by the terrifying ecology of fear to move into much rougher, completely suboptimal areas on the very fringes of the forest where there is significantly less competition and fewer devils.

But that incredible, highly effective behavioral suppression is absolutely not all the devils do; they actively and relentlessly change the entire psychological landscape for the invasive predators.

Tasmanian devils can also create incredibly intense, highly localized territorial pressure simply by aggressively patrolling their massive home ranges and heavily scent-marking the boundaries of their land.

They naturally use many of the exact same vital feeding areas and heavily worn travel corridors, meaning they may directly, physically threaten or aggressively compete with smaller predators on a nightly basis.

When it comes to the highly intelligent, rapidly breeding red foxes, intense, highly aggressive competition can also quickly occur around valuable carcasses and other highly concentrated, limited food sources.

While they are primarily known as robust scavengers, it is important to remember that Tasmanian devils are also highly capable of actively hunting and killing small, vulnerable prey when the vital opportunity arises.

And in some specific, highly documented cases, large, aggressive male devils may actively track down and brutally attack other, smaller predators simply to fiercely protect their own vital territory and eliminate local competition.

They absolutely do not explicitly need to hunt, kill, and turn millions of cats or foxes into their daily food to have a massive, continent-wide ecological effect on the deeply damaged environment.

Simply by actively forcing these highly invasive predators to nervously avoid certain prime areas, drastically change their nightly hunting movements, or permanently lose access to a major part of their food supply, is completely enough.

This intense, constant, naturally occurring pressure is completely enough to trigger a massive, highly beneficial ecological chain reaction that actively cascades down through the entire complex food web.

And that deeply profound, highly complex biological reality is exactly what makes this incredibly ambitious reintroduction project so deeply remarkable and historically important to the entire world.

The dedicated scientists and passionate government officials in Australia are absolutely not simply trying to save one single, highly charismatic native marsupial from the tragic, looming threat of permanent extinction.

If these incredibly resilient Tasmanian devils can successfully continue to breed and firmly establish a highly stable, completely self-sustaining wild population on the mainland, the massive project could accomplish three incredible things at once.

First, it would permanently protect this iconic, deeply loved native predator from the horrific, ravaging effects of the facial tumor disease by keeping a massive, healthy population isolated on the mainland.

Second, it would actively restore a critical, completely missing link in the ancient, deeply complex mainland ecosystem, returning the vital biological process of large-scale scavenging to the natural landscape.

And third, it would ingeniously create massive, constant, completely natural biological pressure on the devastating invasive predators, such as the highly destructive feral cats and the deeply entrenched red foxes.

And that brilliant, multi-layered ecological strategy is exactly how the strategic reintroduction of just one single, keystone species could actively help permanently address three of Australia’s most incredibly serious, seemingly impossible ecological problems.

As the months turned into years, the vast, sprawling natural ecosystem surrounding the newly established devil population also rapidly began to show incredible, highly encouraging signs of positive, large-scale change.

By the momentous year of two thousand and twenty-two, large numbers of native, long-nosed bandicoots had been officially recorded happily returning to many previously empty, heavily damaged parts of the Barrington Tops forest.

Meanwhile, the fiercely beautiful eastern quoll, a small, highly aggressive native predator species that had once completely and tragically become functionally extinct on the entire Australian mainland, also made a massive comeback.

After being carefully and strategically reintroduced to the sanctuary by the Aussie Ark team in two thousand and twenty-one, the quolls rapidly began establishing a highly healthy, thriving, and aggressively expanding population of their own.

Looking closely through the thousands of hours of grainy, infrared camera trap footage, the excited researchers were absolutely no longer seeing just another solitary Tasmanian devil slowly moving through the dark, quiet bush.

They were joyfully beginning to see multiple, highly diverse native species confidently using the exact same massive, complex landscape again, completely free from the relentless, terrifying pressure of feral cats and red foxes.

It was exactly as if a massive, deeply complex ancient forest that had been tragically missing its most important, foundational piece was finally, slowly, and beautifully putting its intricate web of life back together.

But as any seasoned biologist or environmental scientist well knows, Mother Nature is wild, completely unpredictable, and absolutely never follows a perfect, easy, or cleanly written human script.

In the turbulent, highly unpredictable month of May in the year two thousand and twenty-five, a sudden, deeply extreme, and incredibly violent weather event violently struck the coastal region of New South Wales.

This massive, swirling atmospheric anomaly brought days of major, torrential flooding, unexpectedly heavy, freezing snow, and what meteorologists technically and fearfully called a massive, highly destructive weather bomb.

Thousands of ancient, deeply rooted trees were violently brought down by the screaming, gale-force winds, crushing everything in their path and dramatically altering the physical layout of the massive, sprawling sanctuary.

Crucially, large, vital sections of the highly expensive, meticulously engineered predator-proof fencing were severely damaged by the falling timber, creating massive, highly dangerous breaches in the secure perimeter.

Simultaneously, massive, low-lying parts of the animals’ carefully chosen natural habitat were completely and dangerously flooded by the rapidly rising, freezing waters of the overflowing mountain streams.

This time, the completely hands-off approach had to be temporarily abandoned, and the deeply concerned conservationists had no choice but to immediately and urgently step in to prevent a massive, tragic loss of life.

Braving the horrific, freezing conditions and the treacherous, flooded terrain, the team worked around the clock, and some of the most vulnerable Tasmanian devils were quickly recaptured and urgently moved to higher, safer areas.

Then, after months of exhausting, highly expensive repairs to the massive fence line, on the twenty-first of October two thousand and twenty-five, Aussie Ark finally returned fourteen healthy devils back to the Barrington Wildlife Sanctuary.

This highly monitored, carefully planned re-release included exactly twelve strong, aggressive males and two highly valuable, healthy females, carefully chosen to quickly re-establish the complex social hierarchy of the wild population.

Before they were released, each individual animal had been carefully weighed to ensure they hadn’t lost condition, given a highly thorough veterinary health check, and proactively treated for any dangerous, lingering internal parasites.

And this incredibly stressful, highly dramatic, and deeply exhausting weather event ultimately highlighted a very important, incredibly sobering lesson for the entire, ambitious rewilding movement.

Despite the massive, undeniable successes, the fenced area of Barrington Tops is absolutely not yet a completely, entirely self-sustaining, perfectly independent wilderness that can survive without human guardianship.

Dedicated, highly trained humans still have to constantly, physically inspect the miles of complex fences, carefully monitor the health of the animals, and rapidly intervene when massive, completely unpredictable natural disasters occur.

So, while the incredible, unassisted birth of those seven tiny, perfect joeys born in two thousand and twenty-one was a massive, highly celebrated success, it was only the beginning of a much longer journey.

They were unfortunately not yet the ultimate, final kind of massive, continent-wide ecological success that the passionate conservationists and the government of Australia ultimately and desperately hope to eventually achieve.

Those seven resilient joeys definitively proved that Tasmanian devils could incredibly survive, effectively adapt, and successfully reproduce after being completely absent from mainland Australia for more than three thousand long years.

But those early, fenced-in successes did absolutely not definitively prove that millions of feral cat numbers would naturally decline on a continental scale, or that the massive, entrenched fox numbers would ultimately fall.

They also did not definitively prove that vulnerable, heavily preyed-upon native wildlife would be able to successfully and completely recover on a truly massive, nationwide scale without the constant protection of expensive fences.

And they most certainly did not prove that these highly endangered, completely dependent Tasmanian devils could eventually safely expand their wild population completely beyond the physical, protective boundaries of those wire fences on their own.

But this incredibly important, highly complex realization is exactly where the true, incredibly massive scale and the breathtaking, visionary ambition of Aussie Ark’s ultimate master plan officially begins to emerge.

Because despite their incredible fame and crucial biological role, the magnificent, rugged Tasmanian devils are absolutely not the final, ultimate goal of this massive, deeply complex ecological project.

They are purposefully designed to be only the very first, foundational keystone species in a much larger, incredibly ambitious, and deeply complex master plan to fundamentally rebuild the broken food web.

The ultimate, breathtaking goal is to carefully and systematically bring multiple, highly interdependent native animals back to the exact same ancient, sprawling landscape, completely restoring the natural balance of the ecosystem.

Within the massive, highly protected four-hundred-hectare boundaries of the Barrington Wildlife Sanctuary, Aussie Ark actively plans to carefully reintroduce a staggering total of seven critically important, highly threatened native species alongside the Tasmanian devils.

These incredibly vital, carefully chosen native animals include the fiercely beautiful eastern quolls, the highly agile, rock-hopping brush-tailed rock-wallabies, and the incredibly busy, constantly digging rufous bettongs.

The sweeping, highly ambitious plan also heavily relies on the strategic reintroduction of the long-nosed potoroos, the incredibly rare, highly elusive Parma wallabies, and the deeply important, soil-turning southern brown bandicoots.

To truly understand why this multi-species approach is so incredibly vital, imagine a highly complex, perfectly balanced natural scene unfolding deep within the restored sanctuary on any given night.

A massive, incredibly powerful Tasmanian devil slowly and carefully follows the pungent, unmistakable scent of a rotting carcass hidden deeply beneath the towering, swaying branches of the ancient eucalyptus trees.

Somewhere else in the very same dark, quiet forest, a tiny, highly energetic bettong or a long-nosed potoroo naturally lowers its head and frantically begins digging through the thick, damp leaf litter.

Driven by ancient, completely hardwired instincts, these small, highly active marsupials are desperately and constantly in search of highly nutritious underground fungi, hidden roots, and incredibly protein-rich, buried grubs.

Every single time these incredibly busy, small animals relentlessly dig, they aggressively and thoroughly turn over massive amounts of the rich, dark soil completely hidden beneath them on the forest floor.

As they frantically dig and naturally forage for their nightly meals, vital plant seeds, dead, decaying leaves, and highly important, nutrient-rich organic matter are aggressively mixed and constantly moved along with the soil.

Small, seemingly insignificant, highly localized biological actions exactly like these, repeated naturally hundreds of thousands of times every single night, can fundamentally and completely influence the very health of the entire forest.

This constant, relentless biological tilling actively dictates exactly how the soft, porous soil naturally retains vital rainwater during a severe drought, and exactly how essential nutrients are broken down and naturally distributed.

It even directly and completely influences exactly how the diverse, highly complex native vegetation naturally regenerates after a devastating, continent-wide bushfire sweeps through the rugged, dry landscape.

Meanwhile, along the steep, highly treacherous, and jagged rocky slopes of the sanctuary, incredibly agile, heavily muscled brush-tailed rock-wallabies constantly search for secure, high-altitude shelter and vital, low-lying food.

Deep down in the dense, thick, and prickly undergrowth, long-nosed bandicoots relentlessly rummage through the damp, rotting leaf litter, constantly hunting for highly protein-rich insects and small, hidden spiders.

Simultaneously, the fiercely agile, spotted eastern quolls continue their relentless, highly effective nightly hunting of small, vulnerable prey, naturally ensuring that local insect and rodent populations remain completely and perfectly balanced.

And reigning supreme directly above this incredibly complex, deeply intertwined, and highly active biological network, the massive Tasmanian devils fiercely operate as the undisputed, dominant apex scavengers of the restored ecosystem.

They both actively hunt small prey when necessary and aggressively scavenge massive, rotting carcasses, while simultaneously, fiercely, and successfully competing with all other, smaller invasive predators for the limited available food.

The incredibly important, deeply fundamental biological point of this entire, massive scientific endeavor is that absolutely no single, isolated species can successfully and completely restore an entire, deeply broken forest on its very own.

Every single, highly unique, carefully evolved native species actively performs only one very small, highly specific, but incredibly vital part of the massive, deeply complex biological job of maintaining the ecosystem.

The large, dominant native predators naturally and constantly put intense, necessary biological pressure on all the other, smaller animals, effectively preventing any single, aggressive species from completely overpopulating and destroying the habitat.

The small, highly active, digging mammals act as natural, biological ecosystem engineers, relentlessly and constantly digging through the rich soil and aggressively foraging deeply in the damp, decaying leaf litter.

The large, grazing native herbivores actively and completely influence the massive, physical structure of the native vegetation, naturally preventing the dense, thick undergrowth from becoming overgrown and creating a massive fire hazard.

And in a beautiful, deeply complex, and completely natural biological response, all the native plants, ancient trees, and deep fungal networks slowly adapt and respond directly to all of those massive, continuous physical changes.

That deeply intricate, highly complex, and utterly beautiful biological symphony is exactly what the visionary scientists at Aussie Ark are really, truly testing with their massive, highly ambitious rewilding project at Barrington Tops.

They are absolutely not simply releasing one single, highly famous species into the wild, crossing their fingers, and passively waiting for everything else in the heavily damaged environment to magically and instantly change.

Instead, they are painstakingly, deliberately, and incredibly carefully restoring every single missing biological link, one by one, to see whether the ancient, highly complex relationships between them can completely form again.

If this incredibly massive, highly ambitious, and deeply complex ecological experiment actually works over the coming decades, Barrington Tops will rapidly become something far more important than just a safe, fenced-in sanctuary for rare species.

It will quickly and undeniably become one of the most important, highly influential, and globally recognized scientific experiments in the entire, modern history of global environmental conservation and complex ecological restoration.

It will finally, definitively answer the massive, deeply profound question: can humans actually help an ancient, deeply broken ecosystem that has tragically lost many of its key pieces begin to completely function on its own again?

The sweeping, highly emotional, and deeply inspiring story of the return of the Tasmanian devil clearly shows that effectively restoring nature is absolutely not always about simply eliminating a highly harmful, invasive species.

Sometimes, what matters far more in the grand, deeply complex scheme of ecological restoration is actively and carefully bringing back a single, deeply important missing link, like a dominant, heavily muscled apex scavenger.

By doing so, the highly complex, deeply interconnected, and beautifully resilient ecosystem can slowly and naturally begin finding its own perfect, ancient biological balance all over again, exactly as nature originally intended.

But despite the massive, incredible, and highly celebrated successes achieved so far, the sprawling, fenced-in sanctuary of Barrington Tops is fundamentally still only the very first, highly controlled stage of this massive experiment.

And one massive, deeply profound, and incredibly important question still remains completely unanswered for the passionate scientists, the dedicated conservationists, and the hopeful people of Australia.

Could these incredibly resilient, deeply iconic Tasmanian devils one day truly, safely, and completely live freely across the massive, unfenced expanse of mainland Australia once again, exactly as they did thousands of years ago?

Do you personally think this incredibly ambitious, deeply complex, and highly expensive plan is truly worth aggressively expanding across the massive, ecologically diverse continent of Australia?
