Third of shark and ray species face extinction, warns study

Posted on by

Number of species of sharks, rays and chimaeras facing ‘global extinction crisis’ doubles in a decade

A third of shark and ray species have been overfished to near extinction, according to an eight-year scientific study.

“Sharks and rays are the canary in the coalmine of overfishing. If I tell you that three-quarters of tropical and subtropical coastal species are threatened, just imagine a David Attenborough series with 75% of its predators gone. If sharks are declining, there’s a serious problem with fishing,” said the paper’s lead author, Prof Nicholas Dulvy, of Canada’s Simon Fraser University.

ShareAction says lack of plans to tackle climate crisis and biodiversity loss casts doubts on banking’s sustainability pledges

Europe’s 25 largest banks are still failing to present comprehensive plans that address both the climate crisis and biodiversity loss, putting their sustainability pledges in doubt, campaigners have warned.

While some lenders such as NatWest are demonstrating leadership on specific issues – such as net zero targets and policies restricting financing for new fossil fuel – research by investment campaign group ShareAction found none of the banks it reviewed were taking action across all key areas.

‘I’ve never said we should plant a trillion trees’: what ecopreneur Thomas Crowther did next

Posted on by

The ecologist admits ‘messing up’ in the past, but says his Restor project will be ‘a Google Maps of biodiversity’, showing the impact of restoration – from a forest to your own back garden

Listen to our podcast: Can we really solve the climate crisis by planting trees? – part one

Thomas Crowther understands more than most the danger of simple, optimistic messages about combating the climate crisis. In July 2019, the British ecologist co-authored a study estimating that Earth had space for an extra trillion trees on land not used for agriculture or settlement. Its implications were intoxicatingly hopeful. By restoring forests in an area roughly the size of China, the press release accompanying the paper suggested two-thirds of all emissions from human activities still present in the atmosphere could be removed.

The study, led by Jean-François Bastin, a postdoctoral researcher at Crowther’s lab in ETH Zürich, Switzerland, was the second most featured climate paper in the media in 2019, according to one analysis. It inspired the World Economic Forum’s (WEF) One Trillion Trees Initiative, launched last year after Salesforce billionaire Marc Benioff read the paper on the recommendation of Al Gore, the former US vice-president. The Time magazine owner told everyone he could about the research: chief executives, friends and world leaders, even convincing climate sceptic Donald Trump to back the WEF initiative with a multibillion tree commitment.

‘Everything is changing’: the struggle for food as Malawi’s Lake Chilwa shrinks

Posted on by

The livelihoods of 1.5 million people are at risk as the lake’s occasional dry spells occur ever more frequently

• All photographs by Dennis Lupenga/WaterAid

There was a time when the vast Lake Chilwa almost disappeared. In 2012 it had been extremely hot in southern Malawi, with little rain to fill the rivers that ran into the lake.

“Many fishermen were forced to scramble for land near the lake banks, while others had to migrate to the city,” says Alfred Samuel. “We could barely feed our children because the lake could not provide enough fish, or water for rice growing.”

From 1m trees to a tree graveyard: how Dubai’s conservation plans went awry

Posted on by

Hundreds of thousands of trees have died after costly real estate projects thwarted attempts to halt desertification

It all began so beautifully, with the ruler of Dubai photographed planting the first tree of his ambitious environmental initiative, as smiling officials applauded around him.

In 2010, the One Million Trees initiative was announced by Sheikh Mohammed bin Rashid al-Maktoum, the vice president and prime minister of the United Arab Emirates and ruler of Dubai. The aim of the launch was to increase green areas in Dubai through afforestation, while contributing to overall beautification of the city.

Africa’s park tourism crash is a wake-up call. Can we find new ways to finance conservation? | Peter Muiruri

Posted on by

As Covid continues to curb visits to see our iconic wildlife, now is the time to move away from western-led funding models

That African governments have failed to mobilise funds to conserve their vast protected areas is not in doubt. Countries were just about managing to pay basic salaries to rangers who barely had enough to put fuel in their patrol vehicles. Covid has exacerbated this already dire situation, with the loss of income from foreign tourism.

The continent has more than 8,500 protected areas, described by the International Union for Conservation of Nature (IUCN) as government-led national parks, areas jointly governed by state agencies, communities, privately owned wildlife reserves, and public-private partnerships between governments, companies and NGOs. Included too, are what the IUCN calls “indigenous peoples and communities conserved territories and areas”.

One airport, 1,300 snakes: San Francisco helps to save endangered species

Posted on by

A parcel of land owned by the international airport is home to the largest population of the San Francisco garter snake

Across from the San Francisco international airport, and past the bustling highway that hugs it, lies what appears to be an empty lot. But the 180-acre, airport-owned parcel of land, which sits beyond the tarmac, tucked against residential homes, isn’t quite empty. It’s home to roughly 1,300 snakes.

With brightly painted bands of blue, orange-red and black that line their slender bodies, the garter snakes, which can grow up to 3ft long, are considered among the most beautiful in the world. They are also among the most threatened.

Born to be wild: India’s first captive-bred endangered vultures are set free

Posted on by

Numbers of the country’s carrion-loving birds dropped by over 97% in the 1990s. Now, a successful breeding scheme is giving them a boost

In February, the doors of an aviary in West Bengal’s Buxa tiger reserve were flung open. Eight critically endangered captive-bred white-rumped vultures cautiously emerged and within minutes were mingling with wild vultures, devouring the meat of carcasses left out by a team of researchers from the Bombay Natural History Society (BNHS).

The birds were raised in a nearby breeding centre by BNHS, led by assistant director Sachin Ranade, as part of efforts to save India’s Gyps vultures. Gradually, some of the released vultures perched on trees with their wild cousins, while others returned to the wire-mesh aviary where they had spent the previous few months getting acclimatised to their surroundings.

World Elephant Day: inside Kenya’s indigenously run sanctuary for orphans

Posted on by

Established in 2016, the Reteti sanctuary rescues and rehabilitates young elephants so that they can be reintroduced to the wild. It is the first to be owned and run by an indigenous community

In the mountains of northern Kenya, a Samburu community has built a sanctuary for orphaned elephants. Reteti is the first indigenously owned and run sanctuary, which rescues and raises the orphaned elephants, and has the ultimate goal of reintroducing them to the wild.

The sanctuary isn’t just about saving elephants but about breaking down stereotypes and redefining wildlife management. It is the beginning of a transformation in the way the Samburu people relate to wild animals. This oasis where orphans grow up, learning to be wild so that one day they can rejoin their herds, is as much about the people as it is about the elephants.

Trees, grasses and wildlife are returning as Lord Randal Plunkett recreates a vanished landscape in County Meath

Lord Randal Plunkett strides through the hip-high grass of Dunsany, a 650-hectare (1,600-acre) estate in the middle of Ireland, trailed by an invisible swarm of midges and his four jack russell terriers: Tiny, Lumpy, Chow and Beavis & Butt-Head.

The cattle and sheep are long gone, so too are the lawns and many of the crops. In their place is a riot of shrubs, flowers and trees, along with insects and creatures that call this fledgling wilderness their home.

These fragile ecosystems are where the impacts of the climate crisis are often felt first, say experts

The Ebro delta appears to be in robust health, to a casual observer. There is water gurgling in the canals and irrigation channels, and what appears to be a mighty river flowing into the sea. The dazzling green rice fields are dotted with ibis, egrets and redshanks.

However, all is not what it seems. The Ebro, the only one of Spain’s three great rivers that flows into the Mediterranean, is one of the most abused and exploited in Europe.

Researchers find fragments in innards of species that have adapted to develop in open ocean, which has highly polluted areas

Young marine turtles are swallowing large quantities of plastic, with ocean pollution changing habitats that were once ideal for their development into a risk, researchers have found.

The impact of plastic on wildlife is a growing area of research, and studies have revealed harrowing cases of marine animals sustaining injuries or dying after ingesting such material or becoming entangled in it.

Decimated by famine, Florida’s manatees face an uncertain future

Posted on by

2021 is already the deadliest year on record for Florida manatees. Scientists and activists are scrambling to avert further disaster

On a bright morning in July, a crowd gathered on a boat ramp in St Augustine, Florida, awaiting the arrival of a young male manatee named Gerard. The marshy Matanzas River gently flowed around oyster beds and sawgrass islands as biologists organized their equipment. Nearby about a dozen onlookers paced by the shore, waiting to catch a glimpse of Gerard’s return to the wild following weeks of captivity.

Earlier in spring, beachgoers discovered Gerard stranded and sunbaked in Palm Coast, about 25 miles south of St Augustine, on the Atlantic Ocean. Samaritans draped wet towels over the feeble marine mammal, keeping him cool and shaded from the subtropical sun, as a rescue team raced to the scene. Gravely thin, Gerard was transported to Jacksonville Zoo, where he spent the next 10 weeks in critical care until he was plump enough to re-enter the wild.

Blue ticked off: the controversy over the MSC fish ‘ecolabel’

Posted on by

The MSC’s coveted blue tick is the world’s biggest, and some say best, fishery ecolabel. So why is it in the headlines – and does it really do what it says on the tin?

This month, two right whales in the Gulf of St Lawrence were found entangled in fishing gear. One, a female, was first spotted entangled off Cape Cod last year, but rescuers were not able to fully free her; the other, a male, is believed to have become entangled in the Gulf.

Hunted to near extinction before a partial whaling ban in 1935, North Atlantic right whales are once more critically endangered, with only 356 left. The main threat remains human contact: entanglement in fishing gear, and ship strikes. Fatal encounters, caused in part by the whales’ migratory shift into Canada’s snow crab grounds, have soared: more than a tenth of the population died or were seriously injured between 2017 and 2021, mostly in Canada and New England.

The insect apocalypse: ‘Our world will grind to a halt without them’

Posted on by

Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they perform

I have been fascinated by insects all my life. One of my earliest memories is of finding, at the age of five or six, some stripy yellow-and-black caterpillars feeding on weeds in the school playground. I put them in my empty lunchbox, and took them home. Eventually they transformed into handsome magenta and black moths. This seemed like magic to me – and still does. I was hooked.

In pursuit of insects I have travelled the world, from the deserts of Patagonia to the icy peaks of Fjordland in New Zealand and the forested mountains of Bhutan. I have watched clouds of birdwing butterflies sipping minerals from the banks of a river in Borneo, and thousands of fireflies flashing in synchrony at night in the swamps of Thailand. At home in my garden in Sussex I have spent countless hours watching grasshoppers court a mate and see off rivals, earwigs tend their young, ants milk honeydew from aphids, and leaf-cutter bees snip leaves to line their nests.
