The United Kingdom is facing an unprecedented risk of wildfires, with experts stating the likelihood of ignition has never been higher amidst the current record-breaking heatwave. Professor Claire Belcher, a wildfires expert at Exeter University, highlighted that a fire prediction system indicated a 100% chance of a spark igniting a fire in Somerset on Wednesday.
Professor Belcher explained that even a small ember from a bonfire or barbecue, or a spark from agricultural machinery, could lead to a significant blaze under the prevailing conditions. This warning comes as Natural England has issued an alert, urging the public to dispose of cigarettes responsibly and refrain from using disposable barbecues in wild areas due to an "exceptional" fire risk. Several blazes, including a hedgerow fire in Somerset last Saturday, have already been reported across England and Wales in recent days.
The combination of sustained hot and dry weather, coupled with increasing winds and lower humidity, is rapidly drying out vegetation, creating highly combustible conditions. Mark Humphrey, Chair of the National Farmers' Union in Somerset, expressed deep concern among farmers. He noted that they are "very on edge" due to the two weeks of intense heat, fearing that a spark from a combine harvester could quickly engulf dry crops. Fire crews in Somerset recently responded to a combine harvester fire near Wincanton, which was attributed to an accidental cause and damaged a field.
Farmers are also observing significant shifts in weather patterns, with Humphrey noting the dramatic change from widespread flooding in the spring to current drought conditions just four months later. He added that some farmers are already using winter feed for their cattle to cope with the lack of grazing. Tim Parish, a ranger on Exmoor for 24 years, echoed these observations, highlighting a change in the traditional wildfire season. He noted that while fires were typically seen in February and March on Exmoor, the region is now experiencing long, dry spells during peak visitor times, increasing the risk.
Professor Belcher emphasised that while the UK has not historically been a fire-prone country, northern temperate landscapes are increasingly becoming susceptible. She reiterated that dry weather alone does not cause wildfires; an ignition source, such as a discarded cigarette or a barbecue, is also necessary. The ongoing conditions underscore the urgent need for public vigilance and adaptation to these changing environmental challenges.
