Wildfires that hit Wales in July and August burned through more than just vegetation. Researchers from Bangor University say the real damage is underground. At Sychnant Pass, around 10 centimetres of soil was lost, taking with it an organic layer that stored about 4,000 years of carbon. That carbon is now in the atmosphere, and the exposed land is more vulnerable to erosion and future fires. The team is sampling burned and unburned sites before winter rain washes away the remains. Early green shoots can be misleading because bracken regrows from deep roots while heather and gorse are gone. The researchers warn that without restoration and better fire preparedness, these habitats may not recover within a lifetime. For anyone tracking carbon or nature recovery, this is a concrete example of how wildfire turns a long-term carbon sink into an emission source. It also shows why soil, not just trees, needs to be part of climate risk planning.
