The future of peatlands in the UK is becoming increasingly precarious due to the worsening effects of climate change. These unique ecosystems are essential for storing carbon and supporting biodiversity, holding more carbon than all the forests around the globe, even though they only occupy 3% of the world’s land area. Recent studies indicate that large portions of the UK’s peatlands, including the Flow Country, a UNESCO World Heritage Site, may no longer be conducive to peat formation by the years 2061-2080 as a result of climate change.

Researchers are calling for a reevaluation of conservation strategies, as their findings reveal considerable regional variances.
Western Scotland is highlighted as a crucial area for peatland conservation, making it an essential focus for protection efforts.
Through the use of sophisticated bioclimatic models, the research predicts significant declines in the regions that will support peat accumulation throughout the UK, with the Flow Country, Dartmoor, and the Peak District being particularly vulnerable.
Even with moderate reductions in emissions, many of these landscapes may not maintain the conditions necessary for peat formation.
Nevertheless, western Scotland is expected to retain some areas suitable for peatlands, emphasizing its significance for future conservation and restoration initiatives.
Lead researcher Professor Dan Bebber from the University of Exeter stated: “Our findings reveal a stark north-south divide.”
“While western Scotland is likely to remain suitable for peatland, much of England’s peatlands, including Dartmoor and the Peak District, are projected to lose their viability.”
The Flow Country in northern Scotland, which boasts one of the world’s largest blanket bogs, is especially at risk.
If emissions continue to rise (RCP8.5 scenario), as much as 97% of its peatland could become unfit for sustained peat accumulation.
Furthermore, the study indicates a worrying 44-82% rise in drying events affecting Sphagnum moss, a crucial element of peat ecosystems, which could lead to widespread moss die-offs and significant alterations in the landscape.
Professor Angela Gallego-Sala, a co-author and authority on peatland and climate interrelations, commented: “Peatlands are crucial carbon sinks, holding more carbon than all the forests combined. The predicted loss of suitable climates in England and parts of Scotland means we need to adjust our restoration efforts and consider alternative strategies where traditional restoration might not be effective due to the impacts of climate change.”
This research serves as a critical warning to policymakers and conservationists regarding the difficulties of managing peatlands amid a changing climate.
Co-author Dr. Jonathan Ritson from the University of Manchester added: “While our research indicates an uncertain future for peatlands in England, it also highlights the urgent work needed to enable their survival in the changing climate.”
The researchers emphasize the necessity of integrating global emissions reduction efforts with localized strategies to adapt land management and protect ecosystems.
Dr. Kirsten Lees from the University of Derby, who is also co-author of the report, noted: “Understanding peatland resilience is fundamental, as these ecosystems not only sequester substantial carbon but also provide various other services. It’s vital to restore areas in poor condition to safeguard these carbon reserves. Our research illustrates that considering future climate changes is crucial when planning restoration initiatives to ensure they target areas where peatlands can prosper.”
