2025 marks the worst wildfire season in recorded history. As flames have swept across more than 40,000 hectares of British countryside — an area twice the size of Glasgow — the impact on our native wildlife and ecosystems has become impossible to ignore.
Unprecedented Scale
The statistics paint a sobering picture. By August 2025, over 45,748 hectares have been burnt, surpassing the previous annual record set in 2019 by more than 16,000 hectares, with 175 fires larger than 30 hectares recorded. This is an increase of 24 from the previous record set in 2022. This dramatic escalation represents more than just numbers on a spreadsheet; it signifies the wholesale destruction of irreplaceable habitats that have taken decades to establish.
Wildlife Impacts
The immediate casualties of these unprecedented fires extend far beyond the flames themselves. Barn owls in the Amman Valley, south Wales, have seen large areas of their hunting grounds destroyed by fire, leaving them struggling to find food for their young. These magnificent birds, already facing pressures from habitat fragmentation, now confront the complete elimination of their foraging territories.
As concerning is the impact on species already in decline. Skylarks, which have already seen a significant drop in population since the 1970s, are facing even greater challenges as their habitats are wiped out. For these ground-nesting birds, whose distinctive song has long been synonymous with British countryside, the loss of grassland habitats represents a potentially catastrophic blow to their survival prospects.
Invertebrates, often overlooked but crucial to ecosystem functioning, face particular vulnerability as they cannot quickly relocate when fires approach.
Ecosystems in Crisis
Some upland peat bogs may take “hundreds of years” to recover from the current fire damage. These ancient carbon stores, which have developed over millennia, represent some of our most important natural climate solutions. Their destruction releases vast quantities of stored carbon while eliminating crucial habitats for specialised bog communities.
Wildfires have broader environmental consequences, including soil erosion and water pollution. After a fire, the exposed soil can wash away into nearby rivers and streams, affecting water quality and further destabilising ecosystems. This secondary damage often proves more persistent than the fires themselves, creating long-term challenges for habitat restoration.
Climate change, through more temperature and rainfall anomalies, is increasing the risk of wildfires starting and spreading in our forests and woodlands, creating a feedback loop where habitat destruction reduces our natural resilience to further climate impacts.
A Way Forward
We cannot simply treat these fires as isolated incidents; they represent a fundamental threat to UK biodiversity that requires systemic intervention.
Effective wildfire management must combine prevention strategies with habitat restoration programmes specifically designed for fire-resilient ecosystems. This includes establishing early warning systems, rapid response protocols for wildlife rescue and habitat recovery, and increased education and real-time awareness of the risks of accidental fires during dry, warm periods.
The carbon stored in our peatlands, the biodiversity housed in our grasslands, and the ecosystem services provided by our woodlands cannot be replaced quickly once destroyed.
If you are unsure what you can do to help then we list on this website some small ways to improve biodiversity in North Somerset and your immediate surroundings.
