An image of a great glider

When a team of Australian researchers started checking the high-tech boxes they'd installed to help save endangered greater gliders back in 2023, they weren't sure what they were going to find. The hope was that the tree-dwelling marsupials would use them for nesting—a replacement for the tree hollows they normally nest in—but no one knew whether or not the creatures would take to them.

So when Dr. Kita Ashman, Threatened Species and Climate Adaptation Ecologist at WWF-Australia, found a glider in the second box she checked, she was thrilled.

"I just burst into tears, I was so surprised and so happy," she told ABC News Australia.

Greater gliders are nocturnal marsupials that live in old-growth forests of eastern Australia. They have large ears, fluffy fur, long tails, and they can glide up to 100 meters at a time. The species is only found in Australia.

"I grew up looking at greater gliders all throughout the Dandenong Ranges. So they have a really special place in my heart," said Dr. Ashman told ANU.

The special nesting boxes were designed and created through a partnership between Australian National University (ANU), Greening Australia and the World Wide Fund for Nature-Australia after 2019-2020 bushfires destroyed a third of the greater gliders' remaining habitat. The tree hollows that greater gliders rely on to nest can take over 100 years to form, according to ANU, so it's not like they can just find some new trees to live in when their homes are destroyed.

Nesting boxes that are commonly used for wildlife aren't a good fit for greater gliders, as the thin walls and lack of thermal protection can result in gliders overheating. (Heat-stressed gliders will slow their eating, which can be life-threatening, according to ANU.) The high-tech boxes in this project are insulated and include a non-toxic, heat-reflective, fire-resistant coating to keep gliders safe.

"I've affectionately been calling this design the Goldilocks box because we hope it will keep greater gliders not too hot and not too cold and will help to increase the species' resilience in a changing climate," Ashman said in July 2022.

"Producing and installing high-quality nest boxes is costly," added ANU research fellow Dr. Kara Youngentob, "so this project is very important because it will help us understand if expensive interventions like nest boxes are the best use of funding in our urgent mission to save greater gliders."

It appears that their efforts are paying off.

"What we didn't know was whether these boxes worked and whether they have an impact on the glider population," Dr. Youngentob told ABC News Australia. "Much to our delight, within a few months of them going up they are already being used by gliders, so we know the individuals themselves like them and use them."

According to Youngentob, greater gliders are the largest gliding marsupial at risk of extinction. More than 200 nesting boxes have been installed in Victoria's East Gippsland and in Tallaganda National Park in New South Wales. Youngentob told ABC News Australia that this project will help researchers learn more about how many of the species are left in the wild.

The quiet, nocturnal marsupial faces threats from climate change and deforestation in addition to the wildfires that ravaged Australia in 2020. Their population has fallen by 80% in the past 20 years and the species has maintained an endangered status since July of 2022.

"They're a treasure for this country." Dr. Youngentob told ANU. "And I think the more people know about them, the more that they will fall in love with them and want to protect them too."

"We were robbed": Unexpected rejects from the U.S. National Park System

“If the silver discovery hadn’t happened...Lake Tahoe almost certainly would have been a national park."

Lake Tahoe was almost a national park, but politics got in the way.

You know the adage, “Always a bridesmaid, never a bride.” Well, something similar happens out in the wild: not every natural wonder gets to become a national park. For every Yellowstone or Yosemite national park, there are dozens of equally jaw-dropping American landscapes that were denied this coveted designation—and the unparalleled federal protection that comes with it.

From Lake Tahoe’s radiant blue waters to the fossil-rich canyons of Dinosaur National Monument, there are dozens of breathtaking natural beauties across the country that are just that: natural beauties with thriving ecosystems, but not national parks. Behind each rejection, there’s always a fascinating story of politics, competing financial interests, and a constantly changing definition of what “deserves” national protection waiting in the wings.

Often called “the Jewel of the Sierra,” or “Ocean in the sky,” Lake Tahoe is a marvel. Visitors of the 2-million-year-old lake enjoy pristine snow-capped peaks, gorgeous pine trees, and the prettiest, clearest water imaginable. Mark Twain even wrote of Lake Tahoe, “I thought it must surely be the fairest picture the whole earth affords.” Naturally, many people—including Lake Tahoe’s biggest advocate, conservationist John Muir—fought for Lake Tahoe to become a national park, and multiple attempts were made from the 1880s and 1930s.

The problem? Virginia City, Nevada in 1859.

Eighteen hundred and fifty-nine was the year silver was discovered there, and as local historian David Antonucci explains, “If the silver discovery in Virginia City hadn’t happened, the course of history in Lake Tahoe would have been a lot different. It almost certainly would have been a national park."

The resulting mining rush altered Lake Tahoe’s landscape forever, most significantly impacting the tall, ancient trees that dotted the Tahoe Basin, which were systematically chopped down to build mine shafts. Twenty years later, it was estimated that more than 33 million board feet of timber were being cut down annually. To put that into perspective, that’s the equivalent of 2,749,999 cubic feet: the amount of wood required to fill 1,150 shipping containers or 88,000 Olympic-sized pools.

Due to this massive degradation of Lake Tahoe’s precious resources, the National Park Service later concluded that the extensive tourism and land development had compromised the lake’s nature beyond repair, ruling it unsuitable for national park designation.

Why do places seek national park status in the first place? Lake Tahoe has no ego; the land itself does not seek fame, fortune, or glory. But there are several incentives both for the land and the surround communities that make the fight for national park status worth it. National parks enjoy certain VIP privileges, including an army of park rangers and maintenance crews provided by the federal government.

National parks, like the scenic Great Smoky Mountains National Park, Grand Canyon National Park, and Zion National Park, are protected to the highest degree possible against resource extraction, land development and other harmful practices. The are nothing short of astounding: miraculous havens for animals and native plants, flourishing wildlife habitats, and the preservation of vital cultural resources.

Then, there’s the tourism aspect: another powerful motivation for communities to support national park designation is the incredible bump in sightseers—paying visitors—that begin to arrive. National parks are tourist magnets, with Great Smoky Mountain National Park welcoming more than 12 million visitors in 2020. It’s the type of tourism that can turn a rural town into a bucket list destination and economically alter a community forever. Think of the last national park you visited and the crop of tourism-related businesses that surrounded it: lodging, restaurants, themed retail stores, guided tours, and more.

Sadly, Dinosaur National Monument is another destination that never enjoyed national park status and the plethora of perks that come with it. Nestled in the rugged borderlands straddling Colorado and Utah, this huge national treasure spans over 210,000 acres—that’s larger than Bryce Canyon and Zion National Park combined. The natural wonder features an unparalleled 800 paleontology sites and the Carnegie Quarry, which boasts a 150-million-year-old wall full of roughly 1,500 exposed fossilized dinosaur bones.

Dinosaur National Monument also offers astonishing views of the nighttime sky, deeming it an International Dark Sky Park (IDSP) in honor of its exceptional nocturnal environment and supreme views of the cosmos. Obviously, this archaeological beauty would be a shoo-in for national park status, right?

Unfortunately, meddling outside forces struck again: after multiple attempts, Dinosaur National Monument has not been formally rejected as a national park, but it's progress has been stalled for a long time due to local opposition. Commissioners and stakeholders in the area feared that a national park designation would jeopardize their various ranching and energy investments and blocked any attempts to elevate Dinosaur National Monument to national park status.

Becoming a national park is no walk in the park. Rules are scrupulous, community support is vital, and the power of public perception matters. In many ways, that’s a good thing: the National Park Service’s uncompromising criterion ensures precious American tax-payer money is reserved for only the most exemplary resources in the country, both natural and cultural, in a world that, increasingly, seeks to destroy them. But what of Lake Tahoe, Dinosaur National Park, Silver Falls in Oregon, or the Adirondack Mountains?

For reasons that have nothing to do with their importance, significance, or natural beauty, these landscapes lack national park designation and the protections that come with it. But that doesn’t mean they’re not worth visiting. So, the next time you’re planning a nature trip, consider adding these beauties to your list. You just might be pleasantly surprised.

Plastic is a problem for ocean wildlife.

Sometimes taking care of our beautiful home planet looks like big, broad policies tackling issues like plastic pollution and habitat destruction. And sometimes it looks like taking the time to help one tiny creature stuck in an environmental bind.

In a YouTube video that's been viewed a whopping 20 million times, we see an example of the latter in action as some kind and compassionate divers attempt to convince an octopus to abandon the plastic cup it's using for protection and trade it for a sturdy shell. Pall Sigurdsson has shared dozens of underwater videos on YouTube, but watching this particular video from his dive off the coast of Lembeh, Indonesia, in 2018 almost feels like watching a Pixar short film.

"We spent a whole dive and most of our air saving this octopus from what was bound to be a cruel fate," Sigurdsson wrote in the description of the video.

"The coconut octopus, also known as veined octopus, is born with the instinct to protect itself by creating a mobile home out of coconut or clam shells. This particular individual however has been trapped by their instincts and have made a home out of a plastic cup they found underwater."

It's not just that the flimsy plastic cup didn't provide the octopus adequate protection. Sigurdsson explained that a predator like an eel or a flounder would probably end up swallowing the cup with the octopus in it, likely killing both of them. Plus, even if the octopus abandoned the cup on its own, plastic simply doesn't belong in the ocean.

"We tried for a long time to give it shells hoping that it would trade the shell," he wrote. "Coconut octopus are famous for being very picky about which shells they keep so we had to try with many different shells before it found one to be acceptable."

If you think an octopus in a cup making a decision about shells doesn't sound riveting, just watch:

The tentacles reaching out to test the weight of each shell, the divers searching for more options to offer it, the suspense of wondering whether the octopus really would abandon its pathetic plastic pollution protection...it's just too much.

Sigurdsson's other underwater videos are also fun to watch. He shared one of another veined octopus who seemed to have no interest in him but became intrigued with his diver friend, Gary. The way it reaches out to touch just the tip of his finger and then shyly retreats feels like such a clear communication with no words being said.

Octopuses are far more intelligent than anyone would have guessed before we started studying their behavior in earnest. They are known to solve puzzles, escape complicated mazes and traps, and take apart just about anything. It does make you wonder what these little guys were thinking when these divers were interacting with them. Was it curiosity? Judgment? An attempt at connection between species?

It's funny how one small interaction in one tiny portion of the vast ocean can say so much about us, for better and for worse. Human pollution is an enormous problem and saving one little octopus won't save the world, but it sure gives us hope and motivation to keep trying for the sake of the vast number of creatures that live in the ocean as well as our own.

Mama Sekali takes good care of her 3-month old.

There's nothing like the magic of new motherhood, when you find yourself spending hours marveling at the incredible being you helped create and gazing at their impossibly tiny and adorable features. It's sweet when humans do it, but seeing animals have those kinds of tender moments with their babies is so endearing.

Sekali, a Sumatran orangutan who lives at the Toronto Zoo, gave birth to a baby in April 2022. In a video shared by the zoo, the baby gets some "tummy time" while Sekali gently strokes and cuddles him. "Sekali continues to take excellent care of her little one, and he appears to be more alert and mobile," the zoo shared. "Keepers are seeing the baby standing up while holding onto mom and sitting up on his own now, so he is growing stronger each day."

The little guy is cute cute cute, but Sekali picking up his foot and "kissing" it is the sweetest darn thing ever.

People gushed over the video on the zoo's Facebook page.

"LOOKS LIKE ALL MOMMA'S COUNTING THOSE LITTLE TOES AND FINGERS.... SHE APPEARS TO BE SUCH A TENDER MOM!! 🙂 ❤ I LOVE THIS!!!! 🙂" wrote one commenter.

"Clearly his Mom just adores him so much," wrote another. "She is such a good Mom.........he's so sweet and bright-eyed .....a happy and content little guy."

"I’m going to get in trouble for saying this, but, that little one is cuter than a lot of babies!!!! Just look how gentle she is with baby!!!" shared another.

A few months later in August 2022, the Toronto Zoo announced in a press release that the baby orangutan had been christened "Wali," which means "guardian" in Indonesian. Dolf Dejong, CEO of the Toronto Zoo, noted that the name was chosen from a batch of suggestions from the Wildlife Care keepers. Though there were many great suggestions, one stood out as the "clear winner," said DeJong. According to the Zoo's press release, the name felt "fitting since Sumatran Orangutans are the guardians of the rainforests."

While the Sumatran orangutans are seen as guardians, the sad truth is that the species is in trouble.

In 2017, Sumatran orangutans were moved from the International Union for Conservation and Nature (IUCN) Red List of Threatened Species' "endangered" category to "critically endangered," with their habitat in the wild threatened by deforestation, primarily due to palm oil plantations replacing rainforests. According to the Sumatran Orangutan Conservation Programme in 2022, there were only around 14,000 orangutans left in the wild. According to the World Wildlife Fund (WWF), that number has dipped even lower as of 2025.

Orangutan breeding in captivity is not without its controversy, however. The purpose of captive breeding programs like the Orangutan Species Survival Plan is not to release the animals into the wild, but rather to maintain genetic diversity, enable research, and educate the public about these magnificent creatures. Zoos have come a long way in recent decades, creating habitats that look and feel much less like cages and more like the wild, and studies have shown that zoos have a positive impact on people's interest in conservation. Orangutans in human care, like Sekali, may help motivate more people to care about what's happening to the species in their home habitats.

“We are incredibly excited to welcome this new addition to the Toronto Zoo family,” said DeJong. “This orangutan baby is an important contribution to a genetically healthy Sumatran orangutan population in human care. Meanwhile, Sumatran orangutans are under increasing pressure in the wild due to habitat loss and the palm oil crisis, which we are working with partners to address. We are proud to play an important role in the conservation of this amazing species.”

Today, Wali is thriving with mama Sekali and dad Budi. A compilation of his "adorable antics" was shared on YouTube in early January, showing the public what Wali has been up to the last few years. Watch:
