A Massive NZ Effort in Rat Eradication Saves Endangered Birds
Most times, thanks to development and people’s encroachment, endangered species tend to drop in numbers, requiring significant protection to stabilize. However, recently, that hasn’t been the case on the Wellington Miramar Peninsula. Instead, multiple bird species have been exploding in numbers, easily growing their presence into robust populations than can fend off the elements, disease, predators and competition. Overall, this gain in strength has been a 51 percent expansion of original species presence since their last measurement. In some cases, specific species of birds involved have increased their numbers up to 500 percent.
Much of previous risks and threats to the birds involved rodents. Rats as well as possums were notorious for killing birds, particularly the younger ones in nests, essentially culling the numbers and holding them back from any reasonable growth. However, significant efforts under the Predator Free 2050 program have been extremely effective in not only stopping the impact of the rodents but wiping them out from any viable presence as well. It wasn’t an easy battle, however.
The job of eliminating rodents from the Miramar peninsula involved over 11,000 rodent traps alone, as well as all the personnel, time and work involved to check, clear and reset the traps to do their job. Obviously, with any kind of threat, animals learn from experience and observation what could kill them, so the traps had to be altered as well to remain effective. In addition to the crew involved, some 3,000 volunteers and local residents took part in the effort as well. It was essentially an invasion of workers against the rodents and a persistence of eradication.
The rodent list wasn’t limited to the night creepers either. Every major rodent capable of harming the bird populations were targeted. As a result, weasels, stoats, and mustelids were caught up in the bio-dragnet as well. If one could think of a gang task force mission, this probably would have been called Operation Dead Rat or something similar and final.
Tracking and monitoring helped confirm the rat eradication efforts as well. Well over 300 cameras were used in different locations to confirm that the work was having an effect and that personnel were not just being duped by savvy hiding critters. The video work has also been effective in confirming the bird population growth as well. Instead of seeing rodent culprits, birds have been filling the gap left by the dead mammals and confirming their re-establishment now that their threat is gone.
Of course, cats might want to argue that they can help, but the project management has been advising homeowners to keep their cats indoors. Essentially, anything small on four legs is pretty much a target in the Mirimar Peninsula, without exception.
In the vast sand dunes of South Africa, a fascinating creature has emerged from the shadows after being presumed extinct for nearly nine decades. Meet the De Winton golden mole, a blind and elusive species that captivates scientists and conservationists alike. In a thrilling rediscovery, a dedicated team of researchers from the Endangered Wildlife Trust (EWT) and the University of Pretoria successfully located this remarkable golden mole, shedding light on its mysterious existence.
The De Winton golden mole, named after its discoverer Harold De Winton, is a unique and rare mammal characterized by its small size and distinctive golden fur. What makes this creature even more intriguing is its blindness, relying on other heightened senses to navigate its underground world. Though small in stature, the golden mole plays a vital role in maintaining a balanced ecosystem.
Scientists had believed the De Winton golden mole to be extinct since 1936, making its recent rediscovery a momentous occasion. The journey to find this elusive creature spanned two years and involved a combination of innovative techniques, including DNA extraction from soil samples and the keen nose of a specially trained sniffer dog. The successful location of the golden mole in the northwest of South Africa has sparked excitement and renewed hope for its conservation.
Samantha Mynhardt, a conservation geneticist with the Endangered Wildlife Trust and Stellenbosch University, explained the challenges of extracting DNA from soil. Despite these obstacles, the team’s dedication, honed skills, and refined techniques paved the way for success. The ability to find and sequence the DNA of the De Winton golden mole was a crucial step in confirming its existence and understanding its habitat.
The rediscovery of De Winton’s golden mole not only thrilled the scientific community but also proved the resilience of this species. Cobus Theron, senior conservation manager for EWT and a member of the search team, expressed his unwavering faith in the species’ survival. Despite skepticism from some quarters, Theron’s optimism was rewarded as the team celebrated the confirmation that the De Winton golden mole still roams the South African sand dunes.
While the rediscovery is a cause for celebration, conservationists emphasize the importance of continued efforts to protect and preserve the habitat of the De Winton golden mole. As an endangered species, it requires ongoing attention and conservation initiatives to ensure its long-term survival in the ever-changing landscape of South Africa.
Florida’s coastal shores are witnessing a remarkable triumph for sea turtle conservation as nesting records soar to unprecedented heights. The latest data reveals an astonishing 133,840 loggerhead turtle nests and 76,500 green turtle nests, marking an extraordinary success for these ancient mariners on Florida’s sandy beaches.
This wave of sea turtle nesting success is not limited to Florida alone; high numbers have also been reported in South Carolina, Alabama, North Carolina, and Georgia. The positive trend is a testament to the collective efforts of conservationists, volunteers, and communities dedicated to protecting these vulnerable species.
Justin Perrault, the vice president of research at Loggerhead Marinelife Center in Juno Beach, expressed his amazement at the extraordinary numbers. “We had more nests than we had ever seen before on our local beaches,” Perrault stated, emphasizing the significance of this year’s nesting figures. Loggerhead Marinelife Center, which monitors Palm Beach County, broke a local record by recording 4,000 more nests than ever before.
Despite this success, the journey from nest to adulthood remains an arduous one for sea turtles. Approximately one in 1,000 hatchlings survive to reach maturity, facing numerous threats from predators on both land and in the ocean. Nests can be disrupted, and hatchlings may encounter difficulties reaching the water after emerging from their nests.
This year, along a stretch of Florida’s Gulf Coast where 75 nests had been counted, the force of Hurricane Idalia in August took a toll on sea turtle nests. Carly Oakley, senior turtle conservation biologist at Clearwater Marine Aquarium, sadly reported, “Unfortunately, the nests pre-Idalia were almost all lost due to the high tides and flooding on our barrier islands.”
Despite these challenges, the overall success in sea turtle nesting numbers is a cause for celebration. It highlights the resilience of these creatures and the positive impact of conservation efforts. Conservationists, volunteers, and communities continue to play a crucial role in safeguarding sea turtle habitats, implementing “turtle-friendly” practices, and raising awareness about the importance of coexisting harmoniously with these marine treasures.
As Florida breaks records with over 210,000 sea turtle nests, the journey toward ensuring the survival of these remarkable species is a collective effort that spans across coastal states. The challenges faced by sea turtles emphasize the importance of ongoing conservation work, but the record-breaking numbers also serve as a beacon of hope, demonstrating that positive change is possible when communities unite for the well-being of our oceans’ ancient inhabitants.
In a captivating revelation, a new research project in the Arctic has unveiled the existence of a distinct species of ringed seal residing within the Illulissat Icefjord, a designated heritage site in West Greenland. These remarkable seals, known as Kangiat seals, set themselves apart from their ringed seal counterparts with their larger size and distinctive coat coloration.
In the native Inuit language, they are referred to as “Kangiat,” because of their unique presence in the Illulissat Icefjord region. The Kangiat seals represent a small and exclusive population, numbering only a few thousand individuals, and their habitat is primarily confined to the Icefjord area.
What makes these seals truly remarkable is their exceptional isolation from other ringed seals for over a staggering 100,000 years. This lengthy period of isolation has led to the evolution of specific genes and genomic regions that contribute to their distinct characteristics, including their unique coat coloration, larger body size, and adaptations tailored to their specialized fjord habitat.
One notable adaptation in Kangiat seals is their ability to thrive in the unique environment of the Illulissat Icefjord. The lower salt concentration in the fjord water is an important factor influencing their distinctive biology.
While the discovery of Kangiat seals has brought a deeper understanding of the incredible diversity of life in the Arctic, there are still intriguing questions surrounding their origins and evolution. The precise circumstances under which Kangiat seals became isolated and developed their unique biological traits remain an area of continued research and investigation.
As the scientific community delves deeper into the mysteries of Kangiat seals, their presence serves as a reminder of the astonishing and complex tapestry of life in the Arctic, which continues to surprise and captivate researchers and nature enthusiasts alike.

Jane Dotchin, 82-Year-Old Equestrian Adventurer, Embarks on 600-Mile Journey Through Scotland
In a testament to tenacity and tradition, 82-year-old Jane Dotchin, a resident of Hexham, Northumberland, has once again saddled up her trusty pony, Diamond, for an extraordinary 600-mile journey through the north of Scotland. Accompanying her on this annual adventure is her loyal canine companion, Dinky, snugly tucked into a saddlebag. This remarkable journey has been a yearly tradition for Jane since 1972, showcasing her unyielding spirit and love for the open road.
Embarking from her home in Hexham, Jane travels approximately 15 miles a day, braving diverse weather conditions and terrains. Along the way, she stays true to her outdoor roots, sleeping in a tent beneath the expansive Scottish skies. The journey takes seven weeks to complete, a feat that Jane approaches with a combination of meticulous planning and a flexible spirit.
Jane, a familiar face along the route, has forged connections with business owners and community leaders over the years. Her annual sojourn has become a cherished tradition, and she is a welcomed visitor in the communities she passes through.
Fueling her travels with simple yet sustaining meals, Jane relies on a diet of porridge, oatcakes, and cheese. Her journey is a testament to resilience, as she navigates not only the physical challenges of the road but also her impaired vision, aided by an eyepatch.
Equipped with a cell phone that boasts an impressive battery life of six weeks, Jane remains connected to the world, albeit selectively.

Jane’s dedication to her annual pilgrimage is underscored by her refusal to endure harsh weather needlessly. “I refuse to go slogging on through pouring wet rain,” she asserts. Her resilience and adaptability have not gone unnoticed, as she received an Exceptional Achievement Award from the British Horse Society.
In her own words, Jane encapsulates the spirit of her adventurous escapade, “I don’t warn them too far in advance because if the weather changes or I stop early, then they can be left wondering where I’ve got to.” For this intrepid equestrian explorer, age is no barrier to the thrill of the open road and the boundless beauty of the Scottish landscape.
In the heart of California, a monumental endeavor is underway—one that promises to breathe new life into the environment and revitalize the natural world. The ambitious project centers around the removal of the colossal Iron Gate Dam, a massive structure that has obstructed the Klamath River for decades. As this dam is dismantled, nature is poised to make a triumphant comeback, and a vision of rewilding the region is set in motion.
A Glimpse into the History of Iron Gate Dam
The Iron Gate Dam, standing as a formidable barrier on the Klamath River, has a long history dating back to its construction in the early 1960s. The primary purpose of the dam was to generate hydroelectric power and to manage water resources for agricultural and industrial purposes. While the dam served these needs, it also brought about unintended consequences for the surrounding ecosystem.
Over the years, the dam has hindered the natural flow of the Klamath River, disrupting the intricate balance of the ecosystem and impeding the migration of fish, particularly salmon and steelhead. This disruption has had far-reaching effects, causing declines in fish populations and impacting the livelihoods of indigenous communities that rely on the river for sustenance and cultural significance.
A Vision for Restoration and Rewilding
Mark Bransom, the CEO of the Klamath River Renewal Corporation, is at the helm of this ambitious project to remove the Iron Gate Dam. He envisions a future where the Klamath River flows freely once more, unencumbered by the dam’s infrastructure. But it doesn’t stop there. Bransom and his team have elaborate plans to help nature reclaim the area that has long been stifled.
“As soon as the reservoir is drained, we’ll get out on the footprint there and begin some initial restoration activity,” Bransom explained. “We want to stabilize the remaining sediments using native vegetation.”
The concept of rewilding lies at the heart of this vision. Rewilding is a holistic approach to ecosystem restoration that aims to reintroduce native species, rebuild habitats, and allow natural processes to thrive. It’s about creating environments where nature can flourish independently, fostering a healthier and more sustainable ecosystem.
“One of the fastest ways to heal a river is to remove a dam,” says Ann Willis, the California regional director for American Rivers, a nonprofit dedicated to protecting clean water. “The good news is, when you have the opportunity to unjam a river, the river can start to restore itself almost from the moment that the water starts flowing again.”
As the Iron Gate Dam is gradually dismantled, it signifies not only the removal of concrete and steel but also a renewed hope for nature’s resilience. This ambitious project underscores the power of human actions to correct past mistakes and to foster a brighter future where nature can thrive once more.
