Wales wildfires could see nature take centuries to recover – environmentalists

An environment agency has warned that it may take centuries for certain natural habitats in Wales to recover following recent wildfires. Nick Thomas, representing Natural Resources Wales (NRW), explained that the situation is particularly serious in upland peat-rich soils, which regenerate at an incredibly slow rate of about one millimetre annually. If the fires have burned into the soil, the process of rejuvenation for the vegetation could stretch over a very long timeframe.

Mr. Thomas anticipates that 2026 might mark the most severe wildfire season Wales has ever witnessed. He also highlighted that the devastation caused by these fires goes beyond loss of flora and fauna. The destruction of soil in these elevated areas can reduce the land’s capacity to absorb water, escalating the risk of flooding downstream since the soil no longer functions as an effective “sponge.”

This summer, Wales experienced numerous large-scale wildfires, including a significant one near the Rhinogydd mountain range in Gwynedd. This area, known for its National Nature Reserve and designation as a Special Area of Conservation, suffered an intense blaze lasting close to two weeks and engulfing over 2,000 acres. These fires were so extensive that they could be observed from space. Additionally, a fire in Blaenavon, Torfaen, produced smoke detectable as far away as Cardiff. Despite a reduction in wildfire reports during the latter half of July compared to 2025, Mr. Thomas remarked, “This year seems to have been worse, I would say, than any of the ones I can remember.” He added, “I would expect this to probably be the worst year for wildfires perhaps we’ve ever had.”

Regarding recovery prospects, Mr. Thomas pointed out that some areas might bounce back fairly swiftly—possibly within a few years. However, the outcome heavily depends on the intensity of the fire’s penetration into the ground. “If a fire burns into the soil and incinerates the soil… then you’ve lost hundreds of years worth of soil,” he said, emphasising that it could take several centuries for vegetation to return to its previous state.

Local community members who are involved in nature conservation shared their perspectives, expressing deep concern about the ecological impact. Gwyndaf Pritchard, a volunteer from Dwygyfylchi who helps maintain the Pensychnant reserve, described the area as a cherished location for the community and called the loss of wildlife “tragic.” He stressed the urgency of adapting to climate change and adopting measures to prevent future fires. Similarly, Evie Roberts, a silversmith and jewellery instructor at the centre, underscored the need for public awareness around fire safety, especially regarding careless disposal of glass bottles or cigarette ends. Roberts remarked, “Your actions can have devastating effects and I think that education for people is vital to stop this,” noting that wildfires seem to be occurring almost weekly with significant damage to the land
