Floating islands built in Middlesbrough dock as wildlife habitats
The islands have been built from modular units that can be configured into different shapes.They have a total surface area of 600sq ft (180sq m) and it is hoped they will provide shelter for juvenile and migrating fish.The rivers trust is also planning to install artificial rock pools along the walls of the dock to create even more places for wildlife to thrive.
The project was designed in partnership with the Environment Agency (EA), Middlesbrough Development Corporation, Middlesbrough Council and BP.
EA project manager Liz Walters said creating artificial habitats was an "innovative solution which provides an opportunity for nature to thrive"."This work is a great example of local partners joining forces to bring shelter and food for fish and wildlife and support improvements to water quality and biodiversity," she said.

‘Alarmingly high' levels of forever chemicals found at airports in England, investigation reveals
'Alarmingly high' levels of toxic forever chemicals have been detected at English airports – in some cases thousands of times higher than proposed EU safe levels – with experts raising concerns over the potential impact on drinking water sources. Seventeen airports recorded elevated levels of Pfas in the ground and surface water sample on their sites, according to unpublished Environment Agency documents, obtained exclusively by the Ends Report and the Guardian via an environmental information request. Pfas, short for per- and polyfluoroalkyl substances, are a family of about 10,000 chemicals which persist in the environment and have been linked to a range of serious illnesses. They are used in many consumer products, from frying pans to waterproof coats, but one of their most common uses is in firefighting foams. The largest Pfas total recorded was at London Luton airport, with total Pfas in one groundwater sample, taken at a location described as 'fire training lagoon two', of 36,084 nanograms per litre. There is no regulatory limit for Pfas in ground or surface water in the UK, but in the EU a proposed threshold is being considered of 4.4ng/l. While Luton tested for twice the number of Pfas than that included in the EU threshold, the airport's highest total Pfas level was 8,000 times higher than the draft limit. Among the specific Pfas detected at these 17 airports were PFOS and PFOA – two banned and toxic chemicals which, respectively, are suspected and known carcinogens. One sample taken from 'borehole four' at London Luton contained 2,555ng/l of Pfas, with 24ng/l of PFOS and 39ng/l of PFOA. This total Pfas level is more than 500 times higher than the EU's proposed threshold. A London Luton airport spokesperson said: 'Like many airports and other industries in the UK and around the world, we are investing in and working closely with relevant agencies to assess and monitor Pfas.' They added that the data obtained by this investigation was from preliminary screening and should not be considered statistically representative, as a long-term monitoring programme was still under way. Of the airports sampled, Ends Report's analysis has revealed that four of the 17 are located within protected drinking water safeguard zones. These are designated areas set up around public water supplies where additional pollution control measures are needed. One sample taken at Farnborough airport, Hampshire, located in a drinking water safeguard zone, contained 180ng/l of PFOS. The Drinking Water Inspectorate has set a guideline safe level of 100ng/l for the total levels of 48 named Pfas. If test results in drinking water come close to this threshold, then the inspectorate states that precautions should be taken. The presence of elevated Pfas in the sample does not necessarily mean that drinking water is being contaminated by the airport's Pfas pollution. Experts say that for this to happen, pathways would need to exist to enable Pfas to enter drinking water sources. Dr Patrick Byrne, a reader in hydrology and environmental pollution at Liverpool John Moores University, said: 'The risk, if any, to downstream receptors like drinking water sources and ecosystems is unclear. To understand the risk, we need to establish if there is a transport pathway between the source and the receptor. If there is no transport pathway, there is a very low risk.' However, for Dr Shubhi Sharma, from the charity Chem Trust, the high levels of Pfas detected at airports are 'extremely worrying as some of these Pfas have been established as carcinogenic by the World Health Organization'. Dr Rob Collins, director of policy and science at the Rivers Trust, described the Pfas concentrations at UK airports as 'alarmingly high'. While uncertainty remains over the potential risk these may pose, Pfas contamination of drinking water from airports has previously been confirmed close to home. In Jersey, residents have been recommended bloodletting to reduce high concentrations of Pfas in their blood after private drinking water supplies were polluted by the use of Pfas in firefighting foams at the island's airport. In France, one region had to take whole drinking water supplies out of use due to Pfas contamination from an airport. A spokesperson for the trade association AirportsUK said: 'This year UK airports are spending around £5m in investigating the sources and nature of Pfas issues on their sites – it is this industry work that this data comes from. 'This work is being done with a view to identifying specific source locations so that appropriate actions can be assessed. Airports are working closely with the Environment Agency and local communities to ensure that they do not make their way into watercourses and food chains.' A spokesperson for the Department for Environment, Food and Rural Affairs said: 'We are reshaping the UK Reach [chemicals regulation] work programme to deliver stronger protections and are currently considering the best approach to chemicals regulation in the UK, including the development of a restriction dossier on Pfas in firefighting foams'.

Investigative work into cause of crayfish symptoms after many found dead in Northumberland last year
Investigative work is underway in Northumberland to try and identify the cause of unusual symptoms in crayfish, after around 100 were found dead last year. The white clawed crayfish were found dead in the River Wansbeck catchment last autumn, and a subsequent investigation found crayfish displaying similar symptoms were widespread across the area. The endangered native species were seen with unusual orange patches on their shells, and were spotted in the catchments for the neighbouring rivers Tyne and Blyth too. Early surveys carried out by the Environment Agency show that healthy populations still remain in the North East, but symptoms are persisting. Experts are conducting studies across Northumberland and the wider area to identify problem locations, and say looking at the Hart Burn, where the initial deaths were reported, as well as at some other sites, will help them understand the mortality rates in the population. Sarah Jennings, Area Environment Manager at the Environment Agency, said: "There's a lot we still don't know but we hope this new work sheds some light as we continue efforts to safeguard the future of the white clawed crayfish." Surveys of the area could not take place through the winter and spring months due to high river levels. The Environment Agency is working with both the Centre for Environment, Fisheries and Aquaculture Science (Cefas) and experts at Teesside University in efforts to understand more about the situation. Dr Jamie Bojko, Associate Professor in Disease Ecology (Research and Innovation) at Teesside University, said: "We are applying metagenomic and metatranscriptomic methods, in combination with histology, to uncover potential novel pathogens that may be the cause of the shell abnormalities seen in the white claw population." When the dead crayfish were found at the end of September 2024, testing showed negative results for the listed disease white spot syndrome virus, Bunya-like brown spot virus, crayfish plague, and no evidence for any significant bacterial infection was identified. Surveys also show populations of the invasive American signal crayfish are affected by the same symptoms. What can we do to protect the endangered species? River users are being urged to follow advice to prevent the spread of symptoms: Members of that public that spot a crayfish - alive or dead - is advised to leave it alone and report the sighting to the Environment Agency. It is illegal to handle or remove crayfish from the water without the correct licences.

Endangered crayfish returning to Nottinghamshire waterways
A rare species of endangered crayfish is slowly returning to its natural habitats, environmental experts have white-clawed crayfish is the UK's only native species, but it has been under threat for a number of years, particularly following the arrival of the North American signal crayfish in the North American crayfish competes with other native species for food and habitats, and also carries a deadly fungal disease called the crayfish plague, which has been rapidly killing the white-clawed the white-clawed crayfish is now returning to areas of Nottinghamshire following work from environmental groups. The Environment Agency said it has been working with Natural England to secure the white-clawed crayfish's future across the Nottinghamshire, a partnership to protect the species has been formed among various has included the Nottinghamshire Biodiversity Action Group, White Post Farm, and other environmental groups from further and volunteers are creating new safe havens, known as "ark sites", for the crayfish to relocate to, and moving numbers of them that are under threat to these protected McDaid, from the Nottinghamshire Wildlife Trust, said losing the native species would be "heart-breaking".He added: "Our waterways wouldn't be the same if they went extinct as they keep the ecosystems in our rivers healthy. If a native species like that goes, the environment around it is impacted pretty badly."We really want to prevent that, and volunteers play a vital role in helping to stop that from happening." Danielle Grieves, an officer at Natural England, said the work she has observed from volunteers in Bulwell gives her hope for the future of the added: "We are seeing fewer numbers of the North American invasive species in ponds at Bulwell Hall. "It's been so rewarding to see vulnerable, native crayfish being moved to their new homes in Nottinghamshire."By protecting the white-clawed crayfish, we're helping to preserve the biodiversity and ecological health of Nottinghamshire's waterways for future generations."
