Nature recovery requires whole-ecosystem action
With one in six species threatened with extinction in the UK, senior ecologists are calling for an ecosystem approach to halt nature decline.
3 December 2025
A new report by the British Ecological Society and National Trust, co-authored by Newcastle University’s Professor Darren Evans, makes clear that human wellbeing over the coming years and decades will not depend on the extinction or abundance of particular wild species in particular places, but on ecosystems continuing to function in a resilient way.
Despite some conservation successes for individual species, fragmented strategies aren’t big picture enough: one in six species is threatened with extinction in the UK. This threatens the critical ecosystem services upon which society is built upon.
In recent years, UK governments have launched several initiatives to support nature recovery including committing to legally binding targets in the Environment Act. However, these plans focus on disconnected elements of ecosystems (such as species, water quality, carbon) rather than on the whole dynamic picture.
Professor Darren Evans from Newcastle University's School of Natural and Environment Sciences, who is a co-author of the report, said “We now have the tools to model the impacts of environmental change on whole ecosystems. Working with researchers from the Schools of Computing and Mathematics, Statistics and Physics we are applying advances in network science to understand and manage ecosystem functioning in the face of unprecedented change.”
Dr Roly Armstrong, Lecturer in Chemistry at Newcastle University and corresponding author said: “The process we have discovered breaks the strong carbon–fluorine bonds in Teflon®, converting it into sodium fluoride which is used in fluoride toothpastes and added to drinking water.
“Hundreds of thousands of tonnes of Teflon® are produced globally each year – it’s used in everything from lubricants to coatings on cookware, and currently there are very few ways to get rid of it. As those products come to the end of their lives they currently end up in landfill – but this process allows us to extract the fluorine and upcycle it into useful new materials.”

Urgent action needed
Professor Rosie Hails MBE, Director of Nature & Science at The National Trust and chair of the Defra Biodiversity Expert Committee, said, “I’d like to see Defra really leading the charge on an ecosystem approach in England. It’s the department of food, environment and rural affairs and this is in some ways the rural affairs part of their remit, which you hear relatively little about. But this work needs to cut across government departments with Defra connecting up the departments for transport, health and housing.”
