Dam fine: beavers save Czech treasury $1 million
Beavers have saved Czech taxpayers a cool $1 million by flooding a protected former army training site where a long-stalled dam was planned, a conservation official said on Tuesday.
Among nature's great engineers, beavers and their inventions have long been championed by environmentalists for their ability to protect against flooding, improve water quality and boost wildlife.
Officials had hoped to build a barrier to shield the Klabava River and its population of critically endangered crayfish from sediment and acidic water spilling over from two nearby ponds.
As a bonus it would turn a part of this protected area south of the capital Prague into a nature-rich wetland.
First drafted in 2018, the project had a building permit but was delayed by negotiations over the land, long used by the military as training grounds.
Yet before the excavators got the green light to begin digging, the herbivorous rodents set to work building a dam of their own.
"They built a wetland with pools and canals," Bohumil Fiser from the Czech Nature Conservation Agency told AFP.
"The area is roughly twice larger than planned."
- 'Full service' -
The beaver family then moved on to a gulley encircling the ponds, in which the conservationists wanted to build little dams to allow overspill that would help flood the area.
So far the beavers have built at least four dams in the gulley and are currently working on more.
"We were only discussing (building the dams in the gulleys) with the water company and the forest company which owns the land,"
said Fiser, who manages the area.
Fiser said the estimated savings to the Czech purse reached some 30 million Czech koruna ($1.2 million).
"It's full service, beavers are absolutely fantastic and when they are in an area where they can't cause damage, they do a brilliant job," he said.
Despite the good beavers do to the land around them the furry mammals have their critics, with farmers and others complaining of the destruction they cause by felling trees.
But any farmers whose land could be at risk are located far from the site, which was declared a protected area in 2016.
"We don't expect any conflict with the beaver in the next 10 years," Fiser added.

Sao Paulo's pumas under attack as 'stone jungle' threatens rainforest
Apartment blocks and shopping centers sprout like mushrooms around a wild cat sanctuary that shelters pumas recovering from injuries suffered at the hands of mankind in Brazil's Sao Paolo state. The Mata Ciliar refuge stretches over the equivalent of 40 football fields just 90 kilometers (56 miles) from the state capital Sao Paulo -- Latin America's biggest metropolis. Twenty-five pumas and 10 jaguars are receiving treatment at the center -- including Barreiro, a five-year-old puma named after the semi-rural neighborhood where he was found caught in a trap made with a steel cable. Barreiro is being treated for a deep cut to the hip. "Due to the advancement of urbanization into its natural habitat, when the puma moves, it gets lost between roads, gated communities and other human interventions," Mata Ciliar president Jorge Bellix told AFP. As its habitat shrinks in step with human expansion, the puma is forced to move closer to settlements to find food -- which may include pets and livestock, as its natural diet of deer and smaller wild animals gets diminished. The big cats risk being run over by cars, electrocuted by security fences or trapped in snares set by either hunters trying to catch wild boar or residents warding off predators. Some are poached for their skins or as trophies. "If this continues, we will unfortunately witness the extinction of several (animal) species within a few years," said Bellix, whose refuge has treated some 32,000 creatures since it was founded nearly 30 years ago. - 'Stone jungle' - Mata Ciliar also houses monkeys and maned wolves, and is located within the vast Mata Atlantica forest in a country with some of the highest wild cat diversity in the world. But just a few kilometers away looms the grey expanse of Sao Paulo, a metropolis of 21 million people nicknamed the "stone jungle." "The situation is critical: the animals of Sao Paulo are losing the war against urbanization," said veterinarian Cristina Harumi, who helped save Barreiro and hopes he can be returned to the wild soon. The puma, sitting as it does at the top of the food chain, is considered a bioindicator: its disappearance would be an alarming sign of the extent of environmental degradation, she added. The puma, also known as mountain lions, is listed as "near threatened" in Brazil by the International Union for Conservation of Nature (IUCN), which maintains the "Red List of Threatened Species," while mountain lion sub-species outside the Amazon basin are considered "vulnerable." ffb/ll/lg/esp/alh/mlr/jgc

Joy and grief for lone India crash survivor's family
The UK-based family of the lone survivor of the Air India crash were torn on Friday between joy at his miracle escape and grief at the loss of his brother. "We are happy Vishwash has been saved, but on the other hand we are just heartbroken about Ajay," his cousin told AFP outside the family home in central Leicester. Vishwash Kumar Ramesh, 40, is believed to be the only person to have survived the crash when Air India Flight 171 plummeted from the sky shortly after taking off from the northern Indian city of Ahmedabad. His brother, Ajay Kumar Ramesh, was on the same flight, but is believed to have perished in the disaster. There were 242 passengers and crew on the plane, including 53 British citizens. At least 24 people were killed on the ground, officials said, after the aeroplane landed on a canteen building where students were having lunch. Since Thursday's tragedy, the small Leicester street where Ramesh's parents and younger brother lived has been flooded with visitors. Ramesh lives not far away with his wife and son, his cousin Hiren Kantilal, 19, told AFP. Ajay also lived in the town, one of the oldest in England, and the two brothers ran a confectionary business together. "They are wonderful people, and heartful people. They are greatest men I have ever seen in my life, both of them," said Kantilal. The brothers were returning to the UK after spending a few weeks on holiday in India, and the family had been waiting to go and pick them up at Gatwick airport. - 'I am totally fine' - Shortly after the crash, they were shocked when Ramesh, who had reportedly been in seat 11A, called his father to say he was alive. Ajay was seated at the other end of the row. "Our plane has been crashed," Ramesh told his dad, according to his cousin. "He was bleeding all over him, in the face and everything, and he said: 'I am just waiting for my brother and I don't know how I get out of the plane'. "He said: 'do not worry about me, try to find about Ajay Kumar' and he said: 'I am totally fine'." Kantilal said his cousin had waited for about 10 to 15 minutes seeking his brother, and then was whisked away to hospital by the rescue services. Images which went viral on social media apparently showed Ramesh walking away from the wreckage of the 787-8 Boeing Dreamliner, and have been splashed across the front pages of British media along with a photo of him in his hospital bed. Indian Prime Minister Narendra Modi paid a visit to Ramesh on Friday at the hospital where he is being treated for burns and other injuries, footage on his YouTube channel showed. "Everything happened in front of me, and even I couldn't believe how I managed to come out alive from that," Ramesh said from his hospital bed, speaking in Hindi to national broadcaster DD News. His parents had also been desperately trying to contact his brother Ajay on Thursday. "The call was going through, but no-one was answering the call," Kantilal said. At the family home, relatives were frantically scanning their phones to try to buy a flight to Ahmedabad later on Friday afternoon. Downing Street said that the foreign ministry had been in touch with Ramesh to offer him consular assistance. mhc/alm/jkb/bc

‘I realised I was alive': Sole survivor of Air India crash recounts tragedy
The only survivor of the Air India plane crash says he couldn't believe he made it out alive after escaping from a broken emergency exit in a deadly crash that killed 241 people. Shortly after Thursday's crash, social media footage showed Viswashkumar Ramesh limping down the street in a blood-stained t-shirt and with bruises on his body. The British national was sitting in seat 11A on the Boeing 787-8 Dreamliner that was flying in to London when the plane crashed into a medical college hostel moments after taking off from India's northwestern city of Ahmedabad. Ramesh, 40, told India's national broadcaster DD News from his hospital bed on Friday that he thought he was 'also going to die'. 'But when I opened my eyes, I realised I was alive and I tried to unbuckle myself from the seat and escape from where I could. It was in front of my eyes that the air hostess and others [died],' he said. He was travelling with his brother Ajay, who had been seated in a different row, members of his family said. 'The side of the plane I was in landed on the ground, and I could see that there was space outside the aircraft, so when my door broke, I tried to escape through it and I did,' Ramesh said. 'The opposite side of the aircraft was blocked by the building wall so nobody could have come out of there,' he explained that the plane had seemed to have come to a standstill midair for a few seconds shortly after taking off and felt the engine thrust, which later 'crashed with speed into the hostel'. Ramesh's cousin Hiren Kantilal, 19, told the AFP news agency that he called his family in Leicester, in the East Midlands in England, after the crash to tell them he was alive. 'Our plane has been crashed,' Ramesh told his dad, according to his cousin. 'He was bleeding all over him, in the face and everything, and he said, 'I am just waiting for my brother and I don't know how I get out of the plane.' 'He said: 'Do not worry about me, try to find about Ajay Kumar' and he said: 'I am totally fine.'' Kantilal said his cousin had spent about 10 to 15 minutes seeking his brother, and then was whisked away to hospital by the rescue services. 'We are happy Vishwash has been saved, but on the other hand, we are just heartbroken about Ajay,' he told AFP. Indian Prime Minister Narendra Modi visited the crash site on Friday and met Ramesh at the hospital. Rescue workers continued to search for missing people and aircraft parts on Friday following the worst aviation crash in a decade.
