Mapping of England’s Peatlands Reveals Degradation Concerns
Recent mapping efforts indicate that a significant portion, about 80%, of England’s peatlands is currently dry and degraded. This mapping, the first of its kind, utilized satellite imagery, artificial intelligence, and extensive data analysis to create the most comprehensive map of these habitats to date.
An open-source map was made available on the government website this past Monday, providing insights into the extent, depth, and condition of England’s peat. It details various features such as vegetation, gullies, and drainage channels, some of which have been altered by human activity.
Healthy peatlands are known to play an essential role in combating climate change, reducing flood risks, enhancing water quality, and supporting rare wildlife, including species like the Golden Puber, Curl, and numerous dragonflies. Conversely, when peatlands are degraded, they release carbon into the atmosphere, thereby contributing to global warming.
The findings from the map revealed that peat soil occupies roughly 8.5% of England’s land area. The Pennine region, North York Moors, parts of the Lake District, and certain areas in the southwest highlands display the most diverse range of peatland habitats. However, the troubling statistic remains that a vast majority, about 80%, of these peatlands are degraded.
The study further highlighted that around three-quarters of the peatlands are dominated by plants and land uses linked to arid conditions, while merely 1% showcases essential peat-forming plants like Spagnum moss.
Dr. Sally Bailey, Chief Scientist at Natural England, stated the challenges in mapping such subterranean areas: “Mapping peat to this level of detail maximizes the benefits of peat and greatly advances our understanding of the role peatlands play in a changing climate.”
According to Defra, understanding the extent of peat in England is a crucial first step toward calculating its carbon content and managing its release. The Minister hopes that land managers will leverage the map to restore peatlands by implementing practices like blocking drainage channels and re-wetting lands, aligning biodiversity goals with carbon storage and food security.
Tony Juniper, Chair of Nature England, emphasized the importance of healthy peatlands as significant carbon reservoirs and critical components of the water cycle, which support many rare plants and wildlife. He mentioned that the map allows for more informed decisions regarding the management and restoration of these vital ecosystems.
Caroline Thorogood, Peatlands Lead at the National Trust, expressed her enthusiasm about the new mapping trends, highlighting that it would aid in prioritizing future restoration efforts to enhance peatland health, ultimately benefiting both nature and carbon regulation.
