UK’s first ever bison bridges under construction in Kent woodland

News Feed
Friday, September 20, 2024

When Europe’s heaviest land mammals were introduced into a woodland on the edge of Canterbury, it was hoped they would flourish and make space for other wildlife.But the European bison have been so successful in West Blean and Thornden Woods that more space must be made for them – in the form of Britain’s first ever bison bridges.Four bridges costing a total of £1m are being built in to allow introduced bison, which are classified as dangerous wild animals in UK law, to cross the maze of public footpaths in the ancient woods without interacting with people.The hefty grazers – which can weigh up to one tonne – will walk beneath the bridges, with footpaths routed over the top keeping visitors separate while also providing them with a good vantage point to watch the burgeoning bison.The bison herd were released into the woods near Canterbury in July 2022 in a pioneering restoration project by Kent Wildlife Trust and the Woodland Trust. Unknown to the project, one of the three female bison was already pregnant and quickly produced a calf. A bull bison from Germany was added and another calf has since been born in the woods, taking the herd to six.Since their release, the bison have roamed in 50 hectares (123 acres) of woodland. The bridges, which are funded by the National Lottery Heritage Fund alongside National Highways, the Michael Uren Foundation, Veolia Environmental Trust, Garfield Weston Foundation and private donors, will enable the herd to traverse 200 hectares.As the key wild engineers of the Wilder Blean project alongside free-roaming pigs and ponies, the bison are breaking up old conifer plantations to create a more natural biodiverse woodland, which will also store more carbon.The European bison is a relative of the steppe bison, which is thought to have become extinct in Britain about 6,000 years ago. The last wild European bison was shot dead in the Caucasus in 1927 but reintroductions from captive breeding populations in zoos have created a resurgent population, with free-ranging herds in many European countries, including Germany, Switzerland and Poland.Bison are ecosystem engineers: they strip bark from trees which creates standing deadwood that supports insects, birds and bats, and their dust-bathing forms patches where burrowing insects thrive. Their trampling of vegetation is also beneficial, creating light and space for wildflowers.Bison help sequester carbon as well: a study in the Southern Carpathian mountains in Romania, where a herd of 170 bison have been reintroduced since 2014, has found that the animals’ impact has helped capture approximately an additional 54,000 tonnes of carbon a year, nearly 10 times more than without the bison.Kent Wildlife Trust hopes that the bison introduction will encourage similar projects across Britain. But conservationists warn that the continued classification of bison as dangerous wild animals – requiring 27 miles of fencing in the Blean Woods complex as well as the bridges to keep them away from the public – makes it expensive for the animals to be brought into other rewilding and restoration schemes. Bison mix with the public in other countries, including on rewilding schemes in the Netherlands.skip past newsletter promotionThe planet's most important stories.

When Europe’s heaviest land mammals were introduced into a woodland on the edge of Canterbury, it was hoped they would flourish and make space for other wildlife.

But the European bison have been so successful in West Blean and Thornden Woods that more space must be made for them – in the form of Britain’s first ever bison bridges.

Four bridges costing a total of £1m are being built in to allow introduced bison, which are classified as dangerous wild animals in UK law, to cross the maze of public footpaths in the ancient woods without interacting with people.

The hefty grazers – which can weigh up to one tonne – will walk beneath the bridges, with footpaths routed over the top keeping visitors separate while also providing them with a good vantage point to watch the burgeoning bison.

From the telegraph to AI, our communications systems have always had hidden environmental cost

The telegraph was hailed for its revolutionary ability to span distance. Now AI is being hailed as a great leap forward. But both came with environmental costs.

The first attempt to lay submarine telegraph cable between Britain and France. Universal History Archive/GettyWhen we post to a group chat or talk to an AI chatbot, we don’t think about how these technologies came to be. We take it for granted we can instantly communicate. We only notice the importance and reach of these systems when they’re not accessible. Companies describe these systems with metaphors such as the “cloud” or “artificial intelligence”, suggesting something intangible. But they are deeply material. The stories told about these systems centre on newness and progress. But these myths obscure the human and environmental cost of making them possible. AI and modern communication systems rely on huge data centres and submarine cables. These have large and growing environmental costs, from soaring energy use to powering data centres to water for cooling. There’s nothing new about this, as my research shows. The first world-spanning communication system was the telegraph, which made it possible to communicate between some continents in near-real time. But it came at substantial cost to the environment and humans. Submarine telegraph cables were wrapped in gutta-percha, the rubber-like latex extracted from tropical trees by colonial labourers. Forests were felled to grow plantations of these trees. Is it possible to design communications systems without such costs? Perhaps. But as the AI investment bubble shows, environmental and human costs are often ignored in the race for the next big thing. The telegraph had a sizeable environmental and social cost. Pictured: workers coiling the first transatlantic telegraph cable in the bilge tanks of the S.S. Great Eastern in 1865. Universal History Archives/Getty From the “Victorian internet” to AI Before the telegraph, long distance communication was painfully slow. Sending messages by ship could take months. In the 1850s, telegraph cables made it possible to rapidly communicate between countries and across oceans. By the late 1800s, the telegraph had become ubiquitous. Later dubbed the “Victorian internet”, the telegraph was the predecessor of today’s digital networks. Building telegraph networks was a huge undertaking. The first transatlantic cable was completed in 1858, spanning more than 4,000km between North America and Europe. The first transatlantic submarine cables made possible rapid communication between the United States and Europe. This 1857 map shows their paths. Korff Brothers, CC BY-NC-ND Australia followed closely behind. European colonists created the first telegraph lines in the 1850s between Melbourne and Williamstown. By 1872, the Overland Telegraph Line between Adelaide and Darwin had been completed. From Darwin, the message could reach the world. There are clear differences between the telegraph and today’s AI systems. But there are also clear parallels. In our time, fibre optic cables retrace many routes of the now obsolete submarine telegraph cables. Virtually all (99%) of the world’s internet traffic travels through deep sea cables. These cables carry everything from Google searches to ChatGPT interactions, transmitting data close to the speed of light from your device to faraway data centres and back. Historical accounts describe the telegraph variously as a divine gift, a human-made wonder, and a networked global intelligence, far from the material reality. These descriptions are not far off the way AI is talked about today. Grounded in extraction In the 19th century, the telegraph was commonly thought of as an emblem of progress and technological innovation. But these systems had other stories embedded, such as the logic of colonialism. One reason European powers set out to colonise the globe was to extract resources from colonies for their own use. The same extractive logic can be seen in the telegraph, a system whose self-evident technological progress won out over environmental and social costs. If you look closely at a slice of telegraph cable in a museum or at historic sites where submarine telegraph cables made landfall, you’ll see something interesting. The telegraph was a technological marvel – but it came at considerable cost. Pictured is an 1856 sample of the first submarine telegraph cable linking Newfoundland and Nova Scotia in Canada. Jemimah Widdicombe, CC BY-NC-ND Wrapped around the wires is a mixture of tarred yarn and gutta percha. Cable companies used this naturally occurring latex to insulate telegraph wires from the harsh conditions on the sea floor. To meet soaring demand, colonial powers such as Britain and the Netherlands accelerated harvesting in their colonies across Southeast Asia. Rainforests were felled for plantations and Indigenous peoples forced to harvest the latex. European colonial powers drove intensified production of gutta-percha despite the environmental and social cost. Pictured: Kayan people in Borneo harvesting the milky latex around 1910. Wikimedia, CC BY-NC-ND Australia’s telegraph came at real cost, as First Nations truth telling projects and interdisciplinary researchers have shown. The Overland Telegraph Line needed large amounts of water to power batteries and sustain human operators and their animals at repeater stations. The demand for water contributed to loss of life, forced dispossession and the pollution of waterways. The legacy of these effects are still experienced today. Echoes of this colonial logic can be seen in today’s AI systems. The focus today is on technological advancement, regardless of energy and environmental costs. Within five years, the International Energy Agency estimates the world’s data centres could require more electricity than all of Japan. AI is far more thirsty than the telegraph. Data centres produce a great deal of heat, and water has to be used to keep the servers cool. Researchers estimate that by 2027, AI usage will require between 4.2 and 6.6 billion cubic metres of water – about the same volume used by Denmark annually. With the rise of generative AI, both Microsoft and Google have significantly increased their water consumption. Manufacturing the specialised processors needed to train AI models has resulted in dirty mining, deforestation and toxic waste. As AI scholar Kate Crawford has argued, AI must be understood as a system that is: embodied and material, made from natural resources, fuel, human labour, infrastructures, logistics, histories and classifications. The same was true of the telegraph. Huge new data centres are being built to service the growth in AI and the wider internet. Pictured: a new Google data centre in the United Kingdom. Richard Newstead/Getty Planning for the future Telegraph companies and the imperial networks behind them accepted environmental extraction and social exploitation as the price of technological progress. Today’s tech giants are following a similar approach, racing to release ever more powerful models while obscuring the far reaching environmental consequences of their technologies. As governments work to improve regulation and accountability, they must go further to enforce ethical standards, mandate transparent disclosure of energy and environmental impacts and support low impact projects. Without decisive action, AI risks becoming another chapter in the long history of technologies trading human and environmental wellbeing for technological “progress”. The lesson from the telegraph is clear: we must refuse to accept exploitation as the cost of innovation. Jemimah Widdicombe works for the National Communication Museum (NCM) as Senior Curator.

Warnings of imports of caged hen eggs as Ukraine and Poland become UK’s biggest suppliers

Shift raises food safety and welfare concerns as imports can bypass standards for domestic producersUkraine and Poland have overtaken other EU countries to become the UK’s biggest egg suppliers, sparking warnings that imports of eggs from caged hens are slipping “through the back door” despite welfare pledges.Freedom of information data from the Animal and Plant Health Agency shows that, while the Netherlands supplied a large proportion of UK eggs in 2022, its share has steadily fallen. By 2025, Ukraine and Poland together accounted for more than 15m kilograms, with Spain, Italy and other southern and eastern European countries also having increased their exports.

Ukraine and Poland have overtaken other EU countries to become the UK’s biggest egg suppliers, sparking warnings that imports of eggs from caged hens are slipping “through the back door” despite welfare pledges.Freedom of information data from the Animal and Plant Health Agency shows that, while the Netherlands supplied a large proportion of UK eggs in 2022, its share has steadily fallen. By 2025, Ukraine and Poland together accounted for more than 15m kilograms, with Spain, Italy and other southern and eastern European countries also having increased their exports.Ukraine has provided the most eggs so far this year by weight at 8m kilograms, followed by almost 7m kilograms from Poland and 5m from Spain, according to data provided up to July this year.Imports of eggs for consumption rose sharply from about 3,500 consignments in 2023 to more than 10,000 in 2024. Although overall tonnage declined, fewer big shipments have been replaced by many small ones from regions where caged-hen systems remain widespread.Mark Williams, the chair of the British Egg Industry Council, said UK farmers were being placed at an unfair disadvantage. “Our farmers are asked to invest in ever-higher standards of hen welfare while the government leaves the back door open to eggs produced in a system that is banned in the UK. This is morally wrong and unfair, and the government should not be doing this,” he said.Williams said battery cages outlawed in the UK since 2012 were still commonplace in Ukraine, and that eggs linked to food safety issues in mainland Europe continued to be traded.After Russia invaded Ukraine in 2022, the country’s farms, factories and trade routes were badly hit. To help Ukraine’s economy survive, the UK and EU suspended tariffs on its goods, meaning products such as eggs could be exported without extra costs. Ministers argue this tariff suspension is a deliberate step to support Ukraine during wartime.Williams acknowledged the humanitarian case, but added: “Aid should not come at the expense of UK egg farmers – particularly when British retailers have already pledged to go cage-free by 2025. That promise is undermined if imports from countries with weaker welfare standards are allowed to fill the gap into the price-sensitive food service and processing sectors.”The UK currently produces about 88% of its own eggs, and imports the remaining 12%. Leading supermarkets only sell British Lion eggs in retail, following 2017 Food Standards Agency advice confirming they are safe to eat runny or raw. Imported eggs are more likely to be found in restaurants and food processing.“I am not worried about Ukrainian eggs entering retail,” Williams said. “But retail is only 65% of the market. The other two segments – food service (18%) and processing (17%) – are very price-competitive, which makes it attractive for Ukraine to sell eggs or egg products here.”skip past newsletter promotionThe planet's most important stories.

That’s why it’s so attractive right now to send eggs and egg products to the UK.”Ukraine has asked Britain to keep tariff suspensions in place until 2029. While the UK has agreed to extend tariff-free trade on most goods to that date, eggs and poultry are classed as “sensitive products” and have only been granted a shorter, two-year extension.A government spokesperson said: “We are backing our farmers with the largest nature-friendly budget in history to get more British food on our plates and we will always protect our farmers in trade deals.“We are making the supply chain fairer and are engaging with the egg industry to draft new regulations to ensure a level playing field for producers.”
