UK's rarest plants are at risk of extinction, charity warns

The Guardian - Mon, 2017-04-24 09:06

Campaign group Plantlife unveils list of top 10 endangered species and calls for better management of road verges that have become habitats of Britain’s flora

Some of the UK’s rarest plants are at risk of extinction unless action is taken to look after the road verges that have become their final refuge, a charity has warned.

Species such as fen ragwort and wood calamint are now only found on road verges, with fen ragwort hanging on in just one native spot near a burger van on the A142 in Cambridgeshire, conservation charity Plantlife said.

Birds on the battlefield: Country diary 100 years ago

The Guardian - Mon, 2017-04-24 07:30

Originally published in the Manchester Guardian on 27 April 1917

Reports of the arrival of the swallow are coming in thick and fast from all parts of the district; it is impossible to mention them in detail. A few straggled in earlier, but from the 16th onwards they have been arriving or passing in considerable numbers, and now the long-delayed sand martins are with them. On the 22nd a house martin was seen at Stretford. On the 21st, the cuckoo was calling in Hertforshire; we may expect it here any day. Willow wrens, too reported, but so far only odd bird; chiffchaffs, also very late, are now well distributed. Ring ousels and wheatears are on the moors, where twite, curlew, and golden plover are preparing for domestic duties.

Those who imagine that the course of Continental migration is disturbed or deflected should note a report from an officer at the front in France. On the 16th and 17th he saw scores of swallows and sand martins crossing the devastated land, and on the later date noted a house martin, a few tree pipits, two black redstarts, and three scoter ducks. A flock of linnets “insisted on sitting on a derelict bit of telegraph wire where shells fell continually. They were there day after day.” Even the resident birds are little troubled, for my friend adds: “Odd wrens and dunnocks are still in the flattened villages, and a few blackbirds and mistle thrushes.” Another friend comments upon the coltsfoot peeping out everywhere through the shell-torn ground. Nature’s healing touch!

Giant redwoods brought to British shores on a tide of Victorian fashion

The Guardian - Mon, 2017-04-24 06:30

In woods across the UK, an imported American stands higher and broader than the trees that surround it

A wooded ridge overlooking the Ouzel Valley in Bedfordshire has a remarkable set of trees sticking head and shoulders above the rest.

Credited with being able to grow into the world’s largest living thing, they can reach a height of 100 metres, nearly three times as high as a mature oak.

Bigfoot, the Kraken and night parrots: searching for the mythical or mysterious

The Conversation - Mon, 2017-04-24 06:02

It’s remarkable how little we know about Earth. How many species do we share this planet with? We don’t know, but estimates vary from millions to a trillion. In some respects we know more about the Moon, Mars and Venus than we do about the ocean’s depths and the vast sea floors.

But humans are inquisitive creatures, and we’re driven to explore. Chasing mythical or mysterious animals grabs media headlines and spurs debates, but it can also lead to remarkable discoveries.

The recent photographing of a live night parrot in Western Australia brought much joy. These enigmatic nocturnal birds have been only sporadically sighted over decades.

Another Australian species that inspires dedicated searchers is the Tasmanian tiger, or thylacine. A new hunt is under way, not in Tasmania but in Queensland’s vast wilderness region of Cape York.

Other plans are afoot to search for the long-beaked echidna in Western Australia’s Kimberley region.

In the case of the thylacine, old accounts from the region that sound very much like descriptions of the species raise the prospect that perhaps Cape York isn’t such a bad place to look after all.

But in reality, and tragically, it’s very unlikely that either of these species still survives in Australia. For some species there is scientific research that estimates just how improbable such an event would be; in the case of thylacines, one model suggests the odds are 1 in 1.6 trillion.

Chasing myths

The study and pursuit of “hidden” animals, thought to be extinct or fictitious, is often called cryptozoology. The word itself invites scorn – notorious examples include the search for Bigfoot, the Loch Ness Monster or Victoria’s legendary black panthers.

The search for Bigfoot is an extreme case of cryptozoology.

Granted, it’s probably apt to describe those searches as wild goose chases, but we must also acknowledge that genuine species – often quite sizeable ones – have been discovered.

Remarkable discoveries of animals thought to be fantasies or long extinct include giant squid, mountain gorillas, okapi, Komodo dragons and coelacanths.

In some cases, like the giant squid, these animals have been dismissed as legends. The reclusive oarfish, for example, are thought to be the inspiration for centuries of stories about sea serpents.

Oarfish can grow up to 8 metres long and swim vertically through the water. Commonly inhabiting the deep ocean, they occasionally come to shallow water for unknown reasons. AAP Image/ Coastal Otago District Office Technology to the rescue

Finding rare and cryptic species is self-evidently challenging, but rapid advances in technology open up amazing possibilities. Camera traps now provide us with regular selfies of once highly elusive snow leopards, and could equally be used with other difficult-to-find animals.

Environmental DNA is allowing us to detect species otherwise difficult to observe. Animal DNA found in the blood of leeches has uncovered rare and endangered mammals, meaning these and other much maligned blood-sucking parasites could be powerful biodiversity survey tools.

Acoustic recording devices can be left in areas for extended time periods, allowing us to eavesdrop on ecosystems and look out for sounds that might indicate otherwise hidden biological treasures. And coupling drones with thermal sensors and high resolution cameras means we can now take an eagle eye to remote and challenging environments.

Drones are opening up amazing possibilities for biological survey and wildlife conservation. The benefits of exploration and lessons learned

It’s easy to criticise the pursuit of the unlikely, but “miracles” can and do occur, sometimes on our doorstep. The discovery of the ancient Wollemi pine is a case in point. Even if we don’t find what we’re after, we may still benefit from what we learn along the way.

I’ve often wondered how many more species might be revealed to us if scientists invested more time in carefully listening to, recording and following up on the knowledge of Indigenous, farming, and other communities who have long and intimate associations with the land and sea.

Such an approach, combined with the deployment of new technologies, could create a boom of biological discovery.

Jon Vogler obituary

The Guardian - Mon, 2017-04-24 02:23

My father, Jon Vogler, who has died aged 77, used his skills as an engineer to set up the UK’s first large-scale recycling system. In 1974, when recycling at home was virtually unknown in Britain, Jon designed a household scheme in West Yorkshire for Oxfam called Wastesaver.

His innovative “dumpy” device, made of metal tubing, held four different coloured bags into which households sorted their waste. With the co-operation of Kirklees council, the sorted material was collected from 20,000 homes and taken to a disused mill in Huddersfield for recycling. The project revealed for the first time the public’s appetite for such schemes. When the collection of waste became unviable due to fluctuations in commodity prices, Wastesaver changed tack to deal with clothes and textiles.

Do former transport ministers dream of electric buses?

The Guardian - Mon, 2017-04-24 01:53

Ex Lib Dem MP Norman Baker has swapped the ‘constant battle’ of working with Theresa May for running a Brighton eco-firm that’s launching a green bus route

Vince Cable and Ed Davey, the former business and energy secretaries respectively, are among the Liberal Democrats that lost their seats in 2015 who are plotting their way back to parliament in this general election.

But an erstwhile colleague has rejected the opportunity to regain his seat in Lewes in East Sussex. Norman Baker, the former transport minister who later quit the Home Office in 2014 after finding working with Theresa May a “constant battle”, sighs: “I don’t need to do the same thing over and over again, that’s the definition of madness.

Laeticia Brouwer, 17, was killed by a shark in Esperance on Easter Monday but Mark McGowan waited to comment as he did not want to politicise the issue

The premier of Western Australia remains in favour of personal devices to deter sharks instead of culling, nets and drumlines following the death of a 17-year-old girl.

Laeticia Brouwer was surfing with her father during a family holiday in Esperance on Easter Monday when she was mauled on the leg.

Canadian oil firm pulls out of national park in Peru's Amazon

The Guardian - Sun, 2017-04-23 07:22

Pacific abandons one million hectare concession including indigenous peoples’ territories along Brazil border

A Canadian-headquartered company, Pacific Exploration and Production, has pulled out of a huge oil and gas concession overlapping a new national park in the Peruvian Amazon. The concession, Lot 135, includes approximately 40% of the Sierra del Divisor national park established in 2015.

The concession has provoked opposition in Peru and just across the border in Brazil for many years, including regular statements since 2009 from indigenous Matsés people in both countries and a lawsuit recently filed by regional indigenous federation ORPIO. Both Lot 135 and the park overlap territory used by the Matsés and a proposed reserve for indigenous people living in “isolation.”

Hundreds of thousands join March for Science rallies across the world

The Guardian - Sun, 2017-04-23 02:23

More than 600 marches took place around the world in events that coincided with Earth Day, with organizers saying science is ‘under attack’ from Trump

Hundreds of thousands of climate researchers, oceanographers, bird watchers and other supporters of science rallied in marches around the world on Saturday, in an attempt to bolster scientists’ increasingly precarious status with politicians.

The main March for Science event was held in Washington DC, where organizers made plans for up to 150,000 people to flock to the national mall. Marchers held a range of signs, some of them attacking Donald Trump, depicting the president as an ostrich with his head in the sand or bearing the words “What do Trump and atoms have in common? They make up everything.”

Christian Earth Day lessons: worship by protectiong creation | Paul Douglas

Climate change is a global pro-life issue

Readers of this column know that I tend to focus on breaking science in the climate and energy areas. Sometimes, I stray into politics and other times, I venture further afield. Today, on Earth Day, I was reflecting on best ways to move real action forward and it is clear to me, and almost everyone in this industry, that building bridges between like-minded groups is key.

Frankly, it isn’t just scientists that are concerned about climate change. Our concerns are shared by business leaders, the insurance industry, defense industries, people who enjoy the outdoors, farmers, and many more. Recently, there has been a movement amongst persons of faith as well. In fact, for some people of faith, taking care of the Earth is a mandate from a higher authority. In this light, and to celebrate a very different voice form my own, the following is a guest post by a well-known meteorologist in the USA, Paul Douglas. It turns out he is also a man of faith as well as a business leader. Thanks Paul.
