Wildfire-ravaged habitats could take centuries to recover, environmentalists say
Habitats belonging to snakes and rare moths have been destroyed after the wildfires this summer.
Wildfire-ravaged habitats in Wales could take centuries to recover, according to an environment watchdog. Nick Thomas from Natural Resources Wales warns that if soil has been incinerated in peat-rich upland areas, which grow at a rate of about a millimeter per year, it may take centuries for vegetation to return. Thomas expects 2026 to be the worst year Wales has experienced in terms of wildfires.
The loss of soil due to these fires could lead to increased flood risks as it no longer functions as a sponge, holding water on high ground. This summer, Wales witnessed significant wildfires, including a major incident and the evacuation of a village in Conwy county. In the Rhinogydd mountain range in Gwynedd, a blaze burned for nearly two weeks, affecting over 2,000 acres.
In Blaenavon, Torfaen, a fire could be smelled as far away as Cardiff. While some areas may recover within a couple of years, Thomas expects this year to be the worst for wildfires in Wales, perhaps even worse than any experienced in the past. The recovery depends on the depth of the fire and whether the soil is incinerated. A significant wildfire in 2018 on Mynydd Llantysilio near Llangollen incinerated about 10cm of peat in some areas, and eight years later, there is still no large patches of heather.
The persistent wildfires in Wales highlight the need for better management of moors and heaths, reduced fuel loads, grazing, and public awareness to prevent such catastrophes.
