The short-tailed roundleaf bat, known scientifically as Hipposideros curtus, was found in 2016 by Nigerian biologist Iroro Tanshi during field research in the Afi Mountain Wildlife Sanctuary in Cross River state.The discovery came decades after the species had last been recorded in the wild during the 1970s.

Researchers had feared that the bat had become extinct after previously documented habitats in parts of Cameroon and Equatorial Guinea disappeared because of deforestation and other human pressures.Tanshi was conducting doctoral research when her team captured the bat during a night expedition.

The scientists had been setting traps near a known bat roost when they noticed one animal that appeared different from the others.She said the bat’s unusually large ears and distinct features led her to consult identification records, which confirmed that the specimen was the short-tailed roundleaf bat.

The discovery prompted further surveys across cave networks in the Afi sanctuary and nearby Cross River National Park. Using harp traps and mist nets, Tanshi and local assistants identified 15 additional bats from the species.The short-tailed roundleaf bat is a small insect-eating mammal that weighs roughly the same as a teaspoon of salt.

Unlike larger fruit bats, it has small eyes and a highly developed nose structure that helps it navigate through darkness using echolocation.Because the species relies heavily on sound and is sensitive to disturbance, researchers have adapted their methods to avoid harming the animals.

Tanshi said she often uses red light during fieldwork because bright lights and noise can affect the bats.The rediscovery highlighted the importance of the Afi sanctuary, a protected rainforest area that supports several threatened species, including gorillas, drill monkeys and other wildlife.

However, Tanshi said she found that public awareness and conservation efforts were often focused on larger animals, while smaller species such as bats received less attention.She said local communities had strong cultural connections with some large mammals and often understood the need to protect them. Bats, however, continued to face threats despite existing conservation protections.

One of the major challenges has been hunting. In some communities, bats are considered a source of food and are traded as bushmeat.Bats have also historically faced negative perceptions in many societies, with some communities associating them with superstition or disease.

Tanshi described attitudes toward bats as complicated, noting that public concerns around diseases such as Ebola and Covid-19 had further influenced perceptions.In response to the threats facing bats and other small mammals, Tanshi and bat specialist Benneth Obitte established the Small Mammal Conservation Organisation in 2016.

The organisation later launched the Zero Wildfire Campaign, aimed at reducing forest fires that damage habitats and threaten wildlife.The campaign introduced colour-coded warning systems to help farmers manage controlled burning and reduce accidental fires.

Tanshi also created a community-based Forest Guardians group to monitor burning activities and respond quickly when fires spread.According to Tanshi, wildfire incidents in the forest area have declined significantly over several years following these efforts.

Her conservation work around the Afi sanctuary has received international recognition. She was named a National Geographic explorer and received environmental awards for efforts to protect the rainforest ecosystem.

A decade after the discovery of the short-tailed roundleaf bat, Tanshi continues to study the biodiversity of Nigeria’s forests and the species that remain hidden within them.The scientist said the rediscovery demonstrated how little is still known about some ecosystems and how species thought to have vanished can sometimes survive unnoticed.

The survival of the bat colony has also raised questions about how conservation strategies can better include smaller and less visible species, particularly in regions facing habitat loss and pressure from human activity.

For researchers working in the Afi sanctuary, the discovery transformed a species once considered lost into a focus of renewed conservation efforts.

A growing number of rewilding projects across Britain are reporting significant ecological improvements, prompting calls for greater recognition of the approach within national nature recovery strategies.

One of the projects highlighting those gains is Heal Somerset, a rewilding site in southwest England that has documented increases in wildlife populations and habitat diversity since restoration efforts began three years ago.According to Heal Rewilding, the charity behind the project, monitoring data show measurable changes in biodiversity across the site.

The number of small mammal species recorded has increased from three to five over the period, while a range of habitats has developed as former agricultural land has been allowed to recover.The project is supported by more than 250 volunteers who contribute to ecological surveys, removal of barbed-wire fencing and other restoration activities.

Community engagement forms a central part of the initiative, with the charity working alongside 15 underserved groups involved in managing and maintaining the site.Participants include people living with dementia, individuals with additional needs and those experiencing financial hardship.

Schools and youth organizations also take part in educational and conservation activities.The site has become an increasingly popular destination for visitors seeking access to natural landscapes undergoing ecological recovery.

Heal Rewilding founder Jan Stannard said many older visitors describe the experience as a reminder of landscapes that were once more common in Britain before decades of agricultural intensification.“An increasing number of people are coming either as visitors or camping and if they are older they are being transported back to a childhood experience of abundance that they will not get in the farmed countryside,” Stannard said.

She said visitors frequently report hearing insects and bird species that have become less common in many agricultural areas.“They are hearing grasshoppers and crickets in the day and birds such as linnet or greenfinch, which are much less common now,” she said.

The ecological transformation has also been evident to staff working on the project since its early stages.Dan Hill, a 25-year-old rewilding ranger who joined Heal Somerset three years ago, recalled arriving when large areas of the site were dominated by rye grass.“I remember seeing the monoculture of rye grass swaying in the wind and thinking, crikey, it’s desolate,” Hill said.He said the pace of ecological change had exceeded his expectations.

“Three years has flown by and so much has changed. It’s incredibly exciting. I’m learning so much,” he said.Hill described the project as evidence of the capacity of ecosystems to recover when human intervention is reduced and natural processes are allowed to re-establish themselves.“Seeing what nature wants to do – it’s very hopeful,” he said.

He added that public response has been an important part of the project’s success.“When you get people coming to the site and they say: ‘I just want to keep coming back, I’ve never seen a site like this before,’ it really puts a smile on your face,” Hill said.Among the features attracting attention are natural wetland systems created by beavers.

The rodents have become increasingly common across eastern Somerset and are widely viewed by conservationists as important ecosystem engineers because of their ability to create ponds and wetlands that benefit a range of species.Heal Rewilding said its latest report was motivated in part by what it viewed as limited coverage of rewilding initiatives in the 2023 UK-wide State of Nature report.

The charity argues that while rewilding has expanded rapidly across Britain, evidence documenting outcomes has not always been systematically collected or incorporated into broader assessments of biodiversity recovery.

“We were struck by how little attention was given to rewilding, despite the extraordinary growth of the movement,” Stannard said.“There are now hundreds of rewilding projects across Britain and many report seeing remarkable ecological changes.”She said the sector must increasingly rely on scientific monitoring and measurable outcomes if rewilding is to become a more prominent component of environmental policy.

“Stories alone are not enough,” Stannard said. “If rewilding is to be fully recognised within national nature recovery strategies, we need robust evidence of its impact.”

The report forms part of a broader effort by conservation groups to demonstrate how rewilding projects can contribute to biodiversity restoration while also delivering social and educational benefits through community participation and public access to recovering landscapes.
