There have been 114 wildfires in the UK already this year, compared with 79 for the whole of 2018, which was a record-breaking year.
Experts fear a dry winter has left countryside more combustible because leaves and other natural debris have not decayed as they would in wet weather. More than 80 square miles of land has already been burnt this year – an area bigger than the size of Glasgow.
In Scotland, fire crews spent four days last week tackling a blaze in Moray – the UK’s biggest ever wildfire. Another fire in Skye spread across five square miles of forestry.
Alex McKinley, one of two Scottish Fire and Rescue Service wildfire tactical advisers, said: “The amount of wildfires we have already had this year passes the amount we had for the whole of 2018.”
The Moray blaze, at Paul’s Hill near Aberlour, destroyed about 23 square miles of land. At its peak, it travelled at 15 miles an hour.
Mr McKinley described the wildfire in Moray as “apocalyptic”. He said: “I was awestruck by the smoke plume that blocked out the sun and went right across the horizon.
“I knew it was a large fire, but what I was met with was an apocalyptic scene.
“We had 80 firefighters and 19 appliances there, but they looked insignificant to the size and scale I was looking down on.”
The inferno was controlled by using fire to fight fire – the first time the tactic had been adopted in Scotland. Mr McKinley said: “We predicted where the fire was going, identified the most appropriate and safe place, lit a fire and that fire proceeded towards the advancing fire. When the two met, there was no fuel left and the fire was extinguished.”
Mr McKinley, a firefighter for 25 years and Highland area station manager, blamed the wildfires on longer dry spells – the result of climate change.
He warned: “We have always had wildfires in Scotland, but the number and intensity of them are definitely increasing. We are going to see bigger and more intense fires.”
Dr David Moore, from the UK National Centre for Earth Observation, said warm spells have increased from 5.3 days to 13.2 days in recent years.
This year’s Easter Monday and February were also the warmest on record in the UK.
Dr Moore said: “When you get a drier or warmer spell, the leaves are able dry out more quickly and take longer to decay. This build-up of leaf litter makes more fuel available to burn.”
