Dead bats in Pitve, July 2019

Two dead bats lying close together on their doorstep were a sad surprise which greeted a couple in Pitve on the morning of July 24th 2019.

Experienced veterinarian Susan Corning looked over the poor distorted creatures and could see no sign of external wounds. The death of a pair of bats with no obvious evidence of injury is unusual.

This led Susan to the suspicion that the bats might have died from poison. Just five days previously, in the early hours of Friday July 19th, the local authorites had performed the second 'fogging' action of the season, spraying the streets  throughout the Jelsa Council region with pyrethroid poison. Was this a coincidence? As a scientist, Susan was suspicious that the two events might be connected. Without going to the trouble and expense of an autopsy, the cause of death cannot be certain. But as bats eat insects, including mosquitoes, that might have been a source of ingestion. The authorities claim that the pyrethroid used, Cipex 10E, is 'harmless to warm-blooded creatures'. This is untrue. It is well established that the active ingredient of Cipex, Cypermethrin, can be fatal to cats. It is probably also toxic to dogs in high concentration, as well as being harmful to humans*. Its action is on the nervous system. If it does not kill the target insects outright, it causes frenetic hyperactivity. On 14th June 2018, for instance, the morning following the 'fogging' action through Pitve, wasps were still busy around a nest they had built right by the road, which had inevitably been sprayed with the cocktail of poisons used that year. Their numbers were reduced from the previous day, and the activity of the survivors was haphazard. It looked as if the poor souls were trying to do their best, against the odds.

So, after the fogging actions,  poisoned insects will still be flying about to be eaten by birds, bats and other insects, causing a trail of collateral damage. Details of individual cases like these bat deaths may be open to question. There is no doubt that the poisons inflicted on the environment by the fogging actions are contributing to a devastating loss of biodiversity on Hvar. The combined effects of the pesticides used by the local auithorities and those used by individual farmers and gardeners are causing ecological disaster. Bats are among those once-plentiful creatures whose numbers have declined drastically.

Finding dead wildlife is not what people come to Dalmatia for. On the contrary, they expect a clean, unpolluted natural environment, filled with nature's exquisite creatures. The only way to fulfil their wish is for the island to 'go organic'!

  • A project on Dartmoor to reprofile the landscape aims to return the springy bog – and carbon store – to its natural condition

    At one of the most remote spots in southern England, Al West skilfully tilts and rotates the bucket of a small digger, like a giant mechanical hand. He lifts turf, and pats it down gently on to the rich, dark brown peat beneath. Above him, the granite stack of Fur Tor looms above the vast, boggy, wild expanse of northern Dartmoor.

    It is repetitive, delicate work, which West carries out with dexterity and care. Within a boundary of white flags, he takes from a borrow pit and fashions a peat embankment across each ditch and depression covering the land, to restore it to its natural smoothness and to stop the rainwater running off down the valley.

  • Castle Douglas, Dumfries and Galloway: Once nearly extinct in Scotland, they are now widespread, and these ones have such beautiful views to enjoy

    Up on the old logging roads near Kirkennan estate, I saw some wild roe deer. They are one of only two deer species that are native to Scotland, as well as red deer. Back in the 1700s, they were almost extinct here, but they can now be found across the country.

    When we were walking the air smelled like fresh rain and wood. The deer were about 100 metres up the hill from us, resting in long, wiry grass and shrubs. From below, we could see their short mahogany fur blending into the vegetation. As we went up the hill we came to their resting place – the deer had gone, but we could see their hazel fur caught in the shrubs and indentations in the grass where they had been lounging.

  • Female named Rounder surrounded by family members when about to give birth to her second calf

    Scientists have managed to film a sperm whale giving birth while other female whales worked together to support the mother and her newborn.

    A team from Project Ceti, an international effort seeking to understand how whales communicate, was in a boat near a pod of 11 whales off the coast of the Caribbean island of Dominica on 8 July 2023.

  • National Trust says one year after reintroduction they are enriching habitats and may be having kits this summer

    They were released this time last year with fanfare, much hope and also, perhaps, a little trepidation.

    Twelve months on, there have been ups and downs for the first beavers to be (officially) reintroduced into the wild in England since the semiaquatic mammals were hunted to extinction 400 years ago.

  • Conserving the watershed of the Tana and improving farming methods is securing water supplies and livelihoods alike in a changing climate

    When in 2017 David Nyoro became one of the first farmers to partner with Africa’s first water fund to conserve the watershed of Kenya’s biggest river, he received 180 high-value avocado seedlings. The 67-year-old’s farming methods had been dominated by annual crops that left large sections of his five-acre piece of land bare, increasing soil erosion and contributing to river sedimentation. “We used to lose a lot of topsoil to the river. Such loss of soil nutrients and poor farming practices meant we had less farm produce,” he says.

    The avocado seedlings enabled him to grow his farm income to close to 2m Kenyan shillings (about £11,500 at today’s exchange rates), with each mature avocado tree yielding 70kg (154lbs) annually. He introduced cover crops to improve soil health and reduce soil erosion and sediment loads.

  • Number fell 23% year on year in 2025 but waste companies say recycling systems still under strain from sheer volume

    More than 6m vapes and vape pods are still being discarded every week in the UK, with waste management companies warning the sheer volume continues to strain recycling systems despite the ban on disposable e-cigarettes.

    According to research by the recycling campaign group Material Focus, the 6.3m vapes and pods thrown away each week in 2025 represented a 23% reduction from the previous year.

  • Lots of us aren’t very keen on bats. But the more we find out about them, the more amazing they turn out to be

    Bats have a bad rep: in a recent survey by the Bat Conservation Trust (BCT), 46% of people expressed negative feelings about bats. But just look at them! Bat carer Liz Vinson, a volunteer with the BCT, calls them “little furry humans with huge jazz hands. They have individual characters: some are divas; some are bone idle.”

    Shirley Thompson, BCT’s honorary education officer, has been championing bats since the 1980s. “I still think they’re magic,” she says. “The more you find out about them, the more you realise what amazing creatures they are.”

  • Driving fast is in ‘the German DNA’, say lovers of the speed-limit free Autobahn, but support in the country for a restriction is growing

    Death-defying thrills are not what draws Lutz Leif Linden to zip down the Autobahn faster than a plane taking off. Instead, the feeling of freedom and an appreciation of technological mastery play a part in his “almost loving relationship” with driving cars faster than most people can imagine.

    The top speed he has reached on the road in Germany, the world’s only democracy without a blanket speed limit on motorways, is 400km/h (249mph). “It’s like an airplane,” said Linden, the president of the Automobile Club of Germany (AvD). “You are faster than an Airbus at start.”

  • This labor-intensive way of eating isn’t for everyone – and I’m not sure it’s for me. It requires planning and flexibility

    When I called Robin Greenfield, an environmental activist and author, his assistant answered. “We’re stopped really quick,” Marielle said, adding “he is harvesting a ton of wild onions right now. He’ll be on in just a minute.”

    I waited, curious to see his haul and bemused by his willingness to delay an interview for wild vegetables. I had called Greenfield, who wrote Food Freedom about the year he grew and foraged 100% of his food, to talk about how possible, or hard, it is to do just that.

  • Rena Effendi’s film Searching for Satyrus began with a quest for the endangered insect that bears her family name. Before long, she was reckoning with secrets, lies and the mysterious life of her wayward dad

    High in the Caucasus mountains, the photojournalist Rena Effendi is searching for the butterfly that bears the name of the father she hardly knew. It is rocky, bleak, beautiful – and impossible. The grass is fried yellow by the increasingly fierce summer sun, the butterfly’s food has been grazed by sheep and, if it exists at all, Satyrus effendi usually flies only as a single insect across a square kilometre of rock, scree and slope.

    A butterfly hunt makes an unlikely subject for a prize-winning documentary, but Searching for Satyrus is a gripping quest that reveals a remarkable part of the world little known to western audiences while examining issues from war and nationalism to global heating and extinction. Ultimately, however, Effendi’s search for her father’s butterfly becomes a moving reckoning with the secrets and lies in her family and the life of her wayward father.
