People planning to enjoy the outdoors in Wales over the Bank Holiday weekend are being urged to act responsibly, amid concerns over increased wildfire risk following recent warm, dry weather.

Natural Resources Wales (NRW) said conditions across the country have raised the risk of grass and wildfires, prompting closer coordination with fire and rescue services and other partners.

NRW officers have been working alongside emergency services to help manage and respond to incidents in recent days.

On Wednesday, NRW deployed a fire-fighting helicopter to carry out targeted water drops on the Elan Valley wildfire, Cwmystwyth, due to the high risk to nature, difficult ground access, forecast winds and lack of significant rainfall.

Since last night, teams have assisted South Wales Fire and Rescue Service at a large wildfire at Waun Wen near Merthyr Tydfil.

With conditions forecast to remain dry over the coming days, Wales is entering an elevated wildfire risk period.

While teams will continue to work around the clock to protect people, nature and property, NRW is also warning of the potential environmental damage caused by lighting fires and using disposable barbecues.

The organisation says such activities can have devastating consequences, particularly during prolonged dry spells when vegetation is more vulnerable to ignition and fire can spread quickly.

Richard Preece, Duty Tactical Manager for Natural Resources Wales, said: “Wales’ landscapes are incredibly special, but they are also vulnerable. It only takes one careless act for a fire to start and quickly get out of control. We’re asking everyone visiting the outdoors this Bank Holiday to think about the consequences of their actions and help us protect our wildlife, our water and our communities.”

As people enjoy the outdoors over the coming Bank Holiday, people are urged to be #WildfireWise by following simple but critical advice:

• never light fires in the countryside.

• only use disposable barbecues where signs say you can, never leave them unattended and ensure they are fully put out before you leave.

• take all litter home, especially glass bottles.

• avoid discarding cigarettes or matches.

• report any signs of fire or suspicious activity immediately by calling 999.

Carl Williams, Arson Reduction Manager for MAWWFRS said: “Wildfires not only divert crews from responding to other emergencies but also expose firefighters to significant risk. These incidents often demand large numbers of personnel, including On‑Call staff who must leave their primary employment to attend incidents and remain deployed for extended periods, placing considerable strain on personnel and resources.

“Unlike building fires, wildfires can burn across vast rural landscapes, threatening nearby homes, farms, livestock, power supplies and key transport routes. Smoke from these fires can also cause road hazards and serious health impacts, particularly for vulnerable people.

“By making responsible choices, the public can help protect firefighters, safeguard communities, and preserve Wales’s countryside for future generations.”

Rhydian Slade-Jones, Landowner Engagement Officer for SWFRS added: “We work closely with Natural Resources Wales, local farmers and landowners throughout the year to identify high risk areas and put preventative measures in place, but we can’t do it alone. Most wildfires in Wales are caused by human activity, so we’re asking everyone to act responsibly. If you see any deliberate fire setting or anti-social behaviour on our hillsides, it is important you report it straight away, your actions can make a big difference in keeping our communities and crews safe.”

While it can be difficult to understand, most wildfires in Wales are started deliberately and are classed as arson. Others are caused by carelessness, often through the inappropriate use of barbecues or open flames in the countryside. Very few wildfires are the result of accidents or natural causes.

Wildfires leave a trail of destruction that can last for years. Trees, plants and wildlife are unable to escape the flames, with whole habitats destroyed in a matter of hours. Fires also have wider environmental impacts, as ash and disturbed soils are washed into rivers, lakes and reservoirs, reducing water quality and harming fish and other aquatic life.

The loss of vegetation increases the risk of soil erosion and flooding, while damaged landscapes can take decades to recover. These fires leave lasting scars on Wales’ much-loved countryside, affecting those who live, work and visit there.

As well as long-term damage to nature and forestry, wildfires put lives at risk. Firefighters, land managers and nearby communities can all be threatened by fast‑spreading fires and smoke, making prevention the safest and most effective protection.
