Expanding Roads in Africa’s Mountains Threaten Endangered Wildlife
As road networks expand into Africa’s mountainous regions, endangered and vulnerable wildlife face increasing risks of roadkill. Experts warn that without better monitoring and conservation efforts, this growing threat could decimate unique biodiversity

The remote mountain regions of the world, once pristine and largely untouched by human development, are becoming increasingly perilous for wildlife. As road networks extend into these rugged terrains, endangered and vulnerable species are facing an ominous new threat—roadkill.
Species such as the African wild dog (endangered), lions and leopards (both vulnerable), elephants (endangered), and honey badgers (near threatened) are at grave risk, according to new research presented by Professor Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences at the University of the Free State. These animals, many classified by the International Union for Conservation of Nature (IUCN) as at risk, face an increasingly perilous existence.

In her compelling presentation at the Southern African Mountain Conference (SAMC2025), she revealed the stark reality that these once-untouched ecosystems are now being invaded by expanding roads that are leading to more wildlife-vehicle collisions, many of them fatal.
“Wildlife in these regions is incredibly vulnerable, and as roads push deeper into mountainous areas, we’re seeing a dramatic rise in roadkill incidents,” said Prof Le Roux. “Among the casualties, we’re finding not just mammals, but also critically endangered birds like the hooded vulture and the steppe eagle.”
The conference, which brought together leading researchers, policymakers, and environmental experts, focused on the dire state of mountain ecosystems, communities, and biodiversity. UNESCO, in partnership with the University of the Free State’s Afromontane Research Unit, the African Mountain Research Foundation, and the Global Mountain Safeguard Research Programme, facilitated the gathering.
For the past several months, Prof Le Roux and her colleagues—Dr Katlego Mashiane, a lecturer at the UFS Department of Geography, and Dr Clara Grilo of the BIOPOLIS project in Portugal—have scoured decades’ worth of data on roadkill, analyzing published papers from 1971 to 2024. The findings were both alarming and illuminating, revealing that the majority of roadkill data available for Africa has emerged only in the 21st century.
A Growing Threat to Wildlife
In mountainous regions, amphibians were found to be the most frequent roadkill victims, while mammals, particularly those most vulnerable to extinction, were most often killed in the low-lying regions. In some high-elevation mountains, nearly 8% of mammals killed on the roads were species classified as endangered or vulnerable. Even more alarming, the roadkill rate in these regions continues to rise as human development accelerates.
“Many smaller species—those weighing less than 1 kilogram—fall victim to vehicles simply because we don’t see them. However, larger mammals, such as elephants or antelope, are often noticed only after the crash,” Prof Le Roux explained. “When these large animals are killed, it’s not just a loss for the species; it’s a loss for us too, as these collisions can cause significant damage to vehicles and pose a danger to human drivers.”
The risk is compounded by unpredictable weather and treacherous mountain roads, where sudden changes in terrain and visibility make it difficult for both drivers and wildlife to react in time. Prof Le Roux and her team noted that the ruggedness of these areas makes it harder for animals to detect oncoming vehicles, raising the likelihood of accidents.

“These regions are already dangerous for drivers, but for wildlife, the roads are a death trap,” Prof Le Roux said. “The increased number of vehicles, combined with better-paved roads, is putting more and more wildlife at risk.”
Using sophisticated tools like Google Earth Engine’s geospatial platform, the researchers analyzed data from a variety of terrains, classifying areas by elevation. High-elevation mountains, defined as regions above 2,000 meters, moderate elevations between 1,500 and 2,000 meters, and lowland areas below 1,500 meters were all found to have significant roadkill rates, particularly among mammals and birds of conservation concern.
Data Gaps and Underreporting
The study highlighted a critical issue: limited data. Despite the alarming trends, the lack of comprehensive, systematic data across much of the African continent has left major gaps in understanding the full scope of the roadkill crisis. Data was available for only 10 countries, and much of the information consisted of ‘snapshots’ rather than long-term, continuous monitoring.
“There is so much we don’t know about the true scale of this issue across Africa, particularly in the central and western regions,” Prof Le Roux lamented. “What we do know is that these collisions are happening in areas that are home to species that exist nowhere else. We cannot afford to ignore the threat to biodiversity in these mountain ecosystems.”
As the push for infrastructure development grows, the consequences for wildlife have never been clearer. The growing mortality rate among vulnerable species, many of which are already at risk of extinction, could result in devastating losses for biodiversity.
Prof Le Roux and her colleagues urge immediate action to mitigate these risks, calling for more comprehensive data collection, better road planning, and the implementation of wildlife corridors to safeguard these precious ecosystems.
“We must recognize that as we expand our roads into these high-risk areas, we’re also taking a toll on the very creatures that make these mountains so unique,” Prof Le Roux said, emphasizing the urgent need for a balanced approach to development and conservation.
As the conference came to a close, one message echoed throughout the halls: The future of Africa’s mountainous wildlife depends on the actions we take now. The clock is ticking, and the road ahead may be the final journey for some of the continent’s most endangered creatures.

Spotted Deer Introduced in Gujarat’s Banni Grasslands, India to Aid Biodiversity Restoration
The translocation, conducted in collaboration with the wildlife conservation initiative Vantara, is part of an effort to enhance biodiversity in one of Asia’s largest and most fragile grassland ecosystems

In a move aimed at supporting ecological restoration in the Banni Grasslands, Gujarat, India, the State Forest Department has introduced 20 spotted deer into a protected 70-hectare area within the landscape. The translocation, conducted in collaboration with the wildlife conservation initiative Vantara, is part of an effort to enhance biodiversity in one of Asia’s largest and most fragile grassland ecosystems. Vantara is a wildlife conservation initiative founded by Anant Ambani, a board member of Reliance Industries, one of India’s largest conglomerates. Vantara operates the Greens Zoological, Rescue and Rehabilitation Centre in Jamnagar, which served as the source facility for the spotted deer.
The spotted deer, also known as chital (Axis axis), were translocated from Vantara’s ex-situ conservation facility in Jamnagar. They were moved in specially designed ambulances and released under the direct supervision of the Forest Department. Vantara provided logistical and veterinary support to ensure adherence to conservation protocols during the process.
The Banni Grasslands, stretching over 2,600 sq. km in Gujarat’s Kutch district, are a unique arid ecosystem that supports a range of wildlife. According to regional biodiversity surveys, 12 species of mammals have been recorded in the area, including six carnivores such as the Indian wolf and striped hyena, and two herbivores, including the Indian gazelle.
Forest officials and experts from Vantara jointly conducted a field assessment ahead of the deer release to evaluate habitat conditions and inform future rewilding strategies. The review included ecological suitability checks and outlined key habitat restoration measures.
Dr. Brij Kishor Gupta, Director of the Greens Zoological, Rescue and Rehabilitation Centre under Vantara, noted the importance of science-driven collaboration in the effort.
“This initiative reflects a collaborative approach to conservation, where scientific expertise and logistical support are combined to strengthen biodiversity in the Banni Grasslands. Contributing to government-led efforts, the focus remains on achieving meaningful conservation outcomes through partnerships grounded in shared objectives.”

The Gujarat Forest Department has been working to manage ecological pressures in Banni through habitat restoration, control of invasive species, and promotion of native grass growth—critical to sustaining herbivore populations and the carnivores that depend on them.
While the introduction of spotted deer is a notable milestone, experts emphasize that such rewilding interventions must be closely monitored. Ecologists point out that herbivore populations can influence vegetation dynamics, and the long-term impact on the grassland’s carrying capacity and predator-prey relationships remains to be studied.
For now, the project marks a rare instance of coordinated public-private conservation action in India’s grasslands—ecosystems often overshadowed by forests and wetlands in national conservation discourse. As such, it could serve as a model for future wildlife restoration efforts in similar landscapes.

How Barn Owls Brought Nature, Knowledge, and Heart to a South African Campus
At the University of the Free State, South Africa, a quiet conservation story unfolds above the bookshelves – reminding us that even academic spaces can grow wings.

High above the rows of books and hushed reading tables of the Sasol Library at the University of the Free State (UFS), something unexpected is taking flight. A pair of barn owls have made their home in the library’s roof, quietly raising their young and shifting the way an entire academic community sees its role in the world. Their story, both poetic and practical, is becoming a symbol of collaboration, compassion, and conservation.
The owls aren’t just guests—they’re catalysts. What began as a distressed bird outside the library in 2023 has transformed into a university-wide initiative blending science, storytelling, and shared stewardship.
“Our library is a living ecosystem”
For Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, the owls are more than a charming anecdote.
“If we consider Shakespeare’s play, All’s Well That Ends Well, then the presence of the owls in the Sasol Library confirms another meaning of that play,”
“Love,” Prof Reddy says, “is not always considered noble, but is something persistent, and our library is not just a building, but a living ecosystem where precious documents, people, and even animals can interact, shape, and nurture our lives.”

That idea—that libraries are not only homes to knowledge, but habitats for life—is now echoed across campus.
A rescue that became a movement
The turning point came when Tanya Scherman, from the Centre for Teaching and Learning, spotted a sick owl near the library—likely a victim of secondary poisoning from a contaminated rodent.
“It appeared that the owl had been poisoned,” she recalls. “I phoned around trying to find more knowledgeable people who could help.”
Her outreach brought in a network of allies, including the Owl Rescue Centre in Pretoria, a local vet, and Prof Francois Deacon from the Department of Animal Sciences.
“As someone passionate about urban wildlife conservation, I saw a great opportunity – not just to support the owls, but to involve students in hands-on learning,” says Prof Deacon.
Together with his postgraduate students, Ruan Higgs and Kaitlyn Taylor, the team designed a custom nesting box and installed a motion-activated infrared camera to monitor owl activity safely. For Scherman, building the box was a family affair.
“I worked with my dad to build it,” she shares. “He’s an avid animal lover too… It was such a special moment to share with my family.”
From research to relationships
The project has already yielded tangible outcomes. In 2023, the owl pair successfully raised two owlets. This year, six eggs were laid—three owlets are visible so far.

“It captures feeding events, chick development, and parental behaviour,” says Prof Deacon. “This kind of passive monitoring is invaluable… These owls are teaching tools.”
Their footage has already formed the basis for student research on owl diet, nesting habits, and ecological adaptation. And the benefits go beyond science.
“What’s been most rewarding was how many people came together around this – from librarians to students to scientists. We built friendships, not just a nest box.”
Even librarian Hesma van Tonder joined a giraffe capture excursion with Deacon’s team. These moments, Deacon says, are where research and real-life adventure meet.
Symbols of wisdom – and survival
For Scherman, the owls touch something deeper than academic interest.
“My grandparents also had a special connection to owls… When we saw the baby owlets, I naturally felt like I was being promoted to an owl-granny!”
She also hopes to change cultural perceptions around these often-misunderstood birds.
“It’s understandable,” she says, “with their eerie calls, white faces, and ghost-like flight. But they are also messengers, protectors, and symbols of wisdom in many traditions.”
From reducing rodent populations naturally to serving as symbols of coexistence, barn owls bring both ecological and educational value.
“A single owl pair can eat hundreds of rodents in a breeding season,” says Prof Deacon. “We found remains of small birds and insects in their regurgitated pellets… which shows just how active and adaptive they are in an urban environment.”
But risks remain—road traffic, noise, and poisoning threaten their safety. That’s why Scherman and Deacon urge the campus community to be mindful.
“Don’t try to help an injured owl yourself,” says Scherman. “Rather contact Prof Deacon or me… We’re here to assist.”
“Awareness builds respect,” Prof Deacon adds. “Simple behaviours, such as keeping windows closed at night near the roost, go a long way.”
Where silence meets storytelling
As word spread, the initiative grew in meaning—turning the Sasol Library into more than a study space. It’s now a symbol of the university’s values in action.
“It is clear that what may be seen as a disruptive incident with an owl swooping into our library space is also a pedagogical and deeply conservation touchdown,” reflects Prof Reddy.
“Our barn owl event tells us that our library is also a space where silence meets storytelling… where every creature’s story has a rightful place.”
Looking forward
The team is already dreaming bigger. Deacon hopes to expand the project into green corridors, rooftop biodiversity zones, and support for species like bats and pollinators. He sees it as the start of a new kind of campus culture—one rooted in curiosity and care.
“If our university matters and is to remain meaningful,” Prof Reddy says, “our accidental visitors have given new impetus to the fact that our library space holds our stories, and they are making places for new ones as part of our responsible societal futures.”
As the owls continue their quiet vigil above the Sasol Library, they leave more than pellets behind. They leave a legacy of connection—between people, nature, and the pursuit of knowledge. And in that space, where a library became a nest, a new kind of learning has taken flight.

Meltwater ponds might have sheltered life during earth’s deep freeze
During this time, the planet was believed to be encased in ice, with global temperatures plummeting to as low as -50°C

In a study published in Nature Communications, scientists from MIT have proposed that shallow meltwater ponds may have provided critical refuges for early complex life during one of Earth’s most extreme ice ages — the “Snowball Earth” period, which occurred between 635 and 720 million years ago.
During this time, the planet was believed to be encased in ice, with global temperatures plummeting to as low as -50°C. Despite the harsh conditions, complex cellular life — known as eukaryotes — managed to survive. The new research suggests that these life forms could have found sanctuary in small, briny pools formed on the surface of equatorial ice sheets.
“Meltwater ponds are valid candidates for where early eukaryotes could have sheltered during these planet-wide glaciation events,” said lead author Fatima Husain, a graduate researcher in MIT’s Department of Earth, Atmospheric and Planetary Sciences, in a media statement. “This shows us that diversity is present and possible in these sorts of settings. It’s really a story of life’s resilience.”
The team drew parallels between ancient equatorial ice sheets and modern Antarctic conditions. They studied contemporary meltwater ponds on Antarctica’s McMurdo Ice Shelf — an area first dubbed “dirty ice” by explorers in the early 20th century. These ponds, formed by sun-warmed dark debris trapped within surface ice, provided a modern analog to the possible melt environments of the Cryogenian Period.
Samples taken from these Antarctic ponds revealed clear signatures of eukaryotic life. Using chemical and genetic analysis, including the identification of sterols and ribosomal RNA, the researchers detected algae, protists, and microscopic animals — all descendants of early eukaryotes. Each pond supported unique communities, with differences shaped largely by salinity levels.
“No two ponds were alike,” Husain noted. “There are repeating casts of characters, but they’re present in different abundances. We found diverse assemblages of eukaryotes from all the major groups in all the ponds studied.”
These findings suggest that meltwater ponds — overlooked in previous hypotheses — could have served as vital “above-ice oases” for survival and even diversification during Snowball Earth.
“There are many hypotheses for where life could have survived and sheltered during the Cryogenian, but we don’t have excellent analogs for all of them,” Husain explained. “Above-ice meltwater ponds occur on Earth today and are accessible, giving us the opportunity to really focus in on the eukaryotes which live in these environments.”
The study was co-authored by MIT’s Roger Summons, Thomas Evans (formerly MIT), Jasmin Millar of Cardiff University, Anne Jungblut of the Natural History Museum in London, and Ian Hawes of the University of Waikato in New Zealand.
By uncovering how life may have persisted through Earth’s frozen past, the research not only deepens understanding of our planet’s history — it may also help inform the search for life on icy worlds beyond Earth.
