Environment Agency figures show severe incidents are weekly occurrence as farms struggle with cost of pollution prevention despite subsidies

Serious pollution incidents in the UK from dairy, poultry and pig farms are now a weekly occurrence, leading to damage to wildlife, fish, farm livestock and air and water pollution.

The Environment Agency in England and its devolved counterparts in Wales and Scotland recorded 536 of the most severe incidents between 2010 and 2016, the worst instances among more than 5,300 cases of agricultural pollution in the period.

Airedale, West Yorkshire Under one board are two young lizards, one buff, one a dramatic charcoal-grey; under another a dark-green frog

It’s all gone a bit quiet down by the river. The breeding season has petered out, and by and large the birds have retired from public life: to moult, to regrow, to regroup. It’s a drab, warm morning. One of the kingfishers hunches over the streaming shallows. A young bullfinch mopes in the low branches of an ash. Damp late-summer greenery – ferns, goosegrass, rosebay willowherb – chokes the pathways.

Here and there, in the riverside woodland, the warden has laid down boards of planking for young adventurers to peer beneath. Typically there’ll be worms and snails, sage-green slugs and hectic centipedes, perhaps a wood mouse’s midden of neatly nibbled cherry pits.

Goldfinches are common in our gardens nowadays. But there is something special about watching them in a wild setting

The tinkling sound is familiar now; as familiar as the chirp of sparrows used to be when I was growing up. In those days, the goldfinch was a special sight: one would occasionally visit our suburban garden, delighting us with its colourful plumage. I can still remember seeing for the first time the bird’s crimson face-patch and – when it flew – a sudden flash of gold in the wings.

How things have changed – and in the goldfinch’s case, for the better. Today I see, or more often hear, goldfinches almost everywhere I go. They fly over our Somerset garden, distracting me as I sit and write; and are constant companions whenever I take the dog for a walk down the lane behind our home.

Reversal of ban shows ‘corporate agenda is king and people and environment are left behind’, say campaigners

The Trump administration’s decision to reverse a ban on the sale of plastic water bottles in some of America’s most famous national parks, including the Grand Canyon, shows “the corporate agenda is king and people and the environment are left behind”, campaigners have said.

Created by Bill Clinton and Barack Obama, the Cascade-Siskiyou monument protects Oregon’s extraordinary biodiversity, from butterflies to trout. But a Trump review threatens to open the landscape to the timber industry

Dave Willis, a grizzled woodsmen and backcountry outfitter, has spent decades laboring to protect the mountains of southwestern Oregon, one of the most beautiful, biodiverse regions in the country.

Through grassroots activism, Willis and his conservationist allies have won the support of two US presidents. In 2000, Bill Clinton created the roughly 52,000-acre Cascade-Siskiyou National Monument, proclaiming it an “ecological wonderland”. Located just outside of Ashland, it was the first such monument established solely for its extraordinary species diversity. It’s a place that harbors rare lilies and endemic trout, Pacific fishers and goshawks, black bears and a stunning array of butterflies.

Don’t get spooked by the pro-fossil fuel lobby: when we abandon petrol and diesel, our whole world is going to change

When it comes to cars, I had a bit of luck this summer. No, I wasn’t loaned the new Tesla Model 3. My street underwent a pavement improvement scheme. All the parking bays were suspended and minicabs no longer idled their engines during the night. I found myself living in an accidental Low Emissions Zone. It was wonderful.

The best I can say about the anti-EV campaign is that it lacks imagination

Populations of gannets, puffins and other marine birds are in freefall, but a crucial scientific study to pinpoint the causes is being blocked, say experts

Bempton Cliffs bird reserve was in fine fettle last week. The last of its population of puffins had departed for the winter a few weeks earlier, while its thousands of young gannets were still being cared for by their parents on the chalk cliffs of the East Yorkshire nature site. For good measure, kittiwakes, cormorants and fulmars were also bathing in the sunshine.

The mysterious islands of the Salish Sea, between British Columbia and Washington State, are home to the ecological artist Jill Bliss, who since 2012 has devoted herself to exploring the isolated region, artistically and literally. The archipelago has its own unique ecosystem, and Bliss’s medleys of mushrooms and other arcane plants, which she calls her “living sculptures”, are gathered during a “daily treasure hunt”, hiking through woods and staying in isolated cabins. “This particular medley was made while lost deep in the woods of Cortes Island,” she says of one of her favourite works (see first image, below). “I first spotted the amanita [toadstool] glowing under the shadows of a downed tree.”

Pressure is mounting against multi-faceted smugglers but the legal case, though strong, is enormously complex

Late on 6 June 2014 Kenyan police, acting on a tip-off, raided a used car lot in Mombasa’s industrial area. Inside Fuji Motors East Africa Ltd, in one of the lock-ups, they found two tonnes of ivory.

Days earlier a white Mitsubishi truck, its paperwork claiming “household equipment” but in fact carrying more than 300 elephant tusks secreted beneath a tarpaulin, had pulled into the yard on Mombasa Island’s dirty northern fringe, far from the tourist hotels and beaches for which the city is famous.

New Forest, Hampshire Marsh flowers provide nectar for a long list of species, from marmalade hoverflies to silver-washed fritillaries

The New Forest rides, named long before many were gravelled to allow cyclists and others ease of access, cut through the inclosures and plantations, serving as motorways for the many small creatures that abound in these woodlands.

Much of the colour here in earlier months has gone. The golden yellow rays of marsh ragwort, Jacobaea aquatica, a plant quickly distinguished from its prolific commoner relative J vulgaris by its broader florets and leaves with a spade-like end, stand out more radiantly because there is so little competition.

A police insider has told the Guardian that the killers of Wayne Lotter may have been following him

Police believe Wayne Lotter’s killer may have followed and targeted the conservationist when he was shot on Wednesday, according to inside sources.

Lotter was stopped and then fatally shot while travelling by taxi from Dar es Salaam airport to a hotel. He had been working in Tanzania for many years, exposing and jailing wildlife poachers and traffickers, and he had received a number of death threats. Tanzania’s director for criminal investigation, Robert Boaz, said a murder investigation was underway.

Clouds cool the planet by reflecting solar energy back to space and also trap heat and radiate it back to Earth. In a Yale Environment 360 interview, physicist Kate Marvel discusses the double-edged effect clouds have on rising temperatures

Clouds perform an important function in cooling the planet as they reflect solar energy back into space. Yet clouds also intensify warming by trapping the planet’s heat and radiating it back to Earth. As fossil fuel emissions continue to warm the planet, how will this dual role played by clouds change, and will clouds ultimately exacerbate or moderate global warming?

Kate Marvel, a physicist at Columbia University and a researcher at Nasa’s Goddard Institute for Space Studies, is investigating the mysteries of clouds and climate change. In an interview with Yale Environment 360, she discusses what is known about the behaviour of clouds in a warming world (they are migrating more toward the poles), why strict controls need to be imposed on geoengineering experiments with clouds, and why she is confident that science and human ingenuity will ultimately overcome the challenge of climate change.

Lib Dem leader Vince Cable questions UK’s commitment to environmental projects after GIB sale to Australian bank Macquarie

The government is facing renewed criticism after pushing through the “disastrous” sale of the Green Investment Bank (GIB) to the Australian bank Macquarie, as fresh concerns are raised over its commitment to environmental projects.

A consortium led by Macquarie agreed to buy the GIB, which was established in 2012 by the coalition government to fund green infrastructure projects such as windfarms and a waste and bioenergy power plant. The consortium also includes Macquarie’s in-house infrastructure fund and the Universities Superannuation Scheme, a pension fund for British higher education institutions.

Minninglow, Derbyshire The Y Not festival site is still a mess, but a walk along the High Peak Trail underlines the resilience of nature

At the top of Gratton Dale, turning into Mouldridge Lane, the familiar white-walled pasture had been transformed. Diggers and tractors swarmed across the fields, beeping frantically. Grass had been churned up everywhere, and serried ranks of portable loos leaned like wearied soldiers. I was baffled. Was this some sort of war re-enactment?

Then I saw the word TONY spelled out in giant letters in the middle of the busiest field, only the Y was drooping and the N was the wrong way round.

State mines minister rejects two applications at reserves west of Cape Tribulation which campaigners say should set a precedent

The “archaic” practice of mining rivers in north Queensland is making a mockery of Australia’s key policy to protect the Great Barrier Reef, wasting multimillion-dollar efforts to cut runoff pollution, its opponents say.

“Instream” mining in Queensland, the only state still allowing the excavation of rivers for gold, tin and silver, is unleashing torrents of fine sediment in one of the reef’s largest catchments.

Wayne Lotter had received numerous death threats while battling international ivory-trafficking networks

The head of an animal conservation NGO who had received numerous death threats has been shot and killed by an unknown gunman in Tanzania.

Wayne Lotter, 51, was shot on Wednesday evening in the Masaki district of the city of Dar es Salaam. The wildlife conservationist was being driven from the airport to his hotel when his taxi was stopped by another vehicle. Two men, one armed with a gun opened his car door and shot him.

Elusive and endangered white-letter hairstreak discovered in a field in the Scottish borders could become the 34th species to live and breed in the country

Scotland has a new species of butterfly: the elusive and endangered white-letter hairstreak has been discovered in a field in Berwickshire, 100 metres from the English border.
