Belgium’s largest wildfire on record broke out in the High Fens nature reserve in Liège province on August 14, 2026, burning 3,000 hectares (7,413 acres) of protected peat bog and forest across the Hautes Fagnes area near the German border, forcing 600 residents in the municipalities of Waimes and Bütgenbach to evacuate, and drawing firefighters and aircraft from Belgium, Germany, Luxembourg, the Netherlands, and the European Union as the fire continued advancing east on August 16, 2026. This article covers the fire’s origin, its record-breaking scale, the communities and ecology affected, why heat and dry peat caused it to spread beyond anything previously seen in Belgium, the multi-country emergency response, and how it fits into the wider pattern of European wildfires burning simultaneously in August 2026.

Belgium’s Largest Wildfire on Record: High Fens, 3,000 Hectares, and a Fire That Doubled the Previous Record
The Belgium wildfire of August 2026 started on Friday August 14 in the High Fens, known in French as the Hautes Fagnes and in German as the Hohes Venn, a large protected nature reserve in the Ardennes uplands of Liège province in eastern Belgium, and by Sunday August 16 had burned 3,000 hectares of peat bog, heath, and forest, making it the largest wildfire in Belgium’s recorded history by a factor of more than two.
Belgium’s previous largest recorded wildfire was a 2011 fire in the same High Fens reserve that burned 14 square kilometres (5.4 square miles). The 2026 fire at 27 to 30 square kilometres has more than doubled that record according to data from the European Forest Fire Information System (EFFIS). Nicolas Yernaux, spokesperson for the Public Service of Wallonia, confirmed that conditions were far more severe than the 2011 fire: “We’re dealing with something much deeper because we have very dry soil.”
The High Fens are not ordinary forest. They form the highest point in Belgium and contain rare raised peat bogs, wet heaths, and blanket peat habitats that take centuries to develop. The reserve is part of the transboundary Hautes Fagnes-Eifel nature park recognised across the Belgium-Germany border. Peat is a dense, water-saturated organic material when healthy; when severely dried, it becomes one of the most difficult wildfire fuels to extinguish because it burns below the soil surface, not just at the surface level where aerial water-bombing is most effective.
As of Sunday, August 16, the fire was not contained. René Dahmen, chief engineer at Belgium’s Department of Nature and Forest, confirmed that on the eastern flank, fire was advancing along a line at least one kilometre wide toward a municipal forest.

600 Residents Evacuated: Waimes, Bütgenbach, and the Communities in the Fire’s Path
Six hundred residents in the municipalities of Waimes and Bütgenbach in Liège province were ordered to evacuate on Saturday, August 15, as the wildfire’s advancing smoke and flames moved into their communities, with the fire’s east-facing direction toward the German border also placing communities across the frontier under smoke alerts.
Waimes and Bütgenbach are both located in the German-speaking area of eastern Belgium, a region culturally and linguistically distinct from French-speaking Wallonia and historically linked to the neighbouring Eifel uplands of Germany. Their proximity to the High Fens means they are directly in the path of any fire originating in the reserve. Residents were directed to evacuation points as wind-driven smoke pushed into residential areas on Saturday afternoon and overnight.
Germany responded to the cross-border dimension. The town of Monschau, just across the Belgian border on the German side, asked residents in nearby areas to leave as a precaution. German authorities specified that the fire was not expected to cross into German territory but that significant smoke pollution was likely in border communities. German firefighters crossed in the other direction, joining Belgian, Luxembourg, and Dutch crews in the containment effort.
The ecological loss from this fire extends beyond the immediate human displacement. Peat bogs are among the most carbon-dense ecosystems on Earth. A single hectare of deep peat stores more carbon than a hectare of tropical forest. When peat burns, it releases carbon dioxide accumulated over centuries. The destruction of 3,000 hectares of peat-dominated habitat in the High Fens represents an ecological loss that cannot be repaired on any human timescale.
Why the Belgium Wildfire Spread So Quickly: 37°C Heat, Weeks Without Rain, and Burning Peat
The Belgium wildfire spread to record-breaking scale because a prolonged absence of significant rainfall had dried the High Fens peat soil to critical depth before temperatures reached 37°C on Friday, August 14, the day the fire started, creating the conditions that allowed a fire to burn not just across the surface of the reserve but into the peat layer beneath.
Belgium and northern France had been experiencing repeated heat pulses through July and into August 2026. On Thursday, August 13, temperatures above 35°C were logged across several European countries. By Friday, August 14, Belgium reached 37°C (98.6°F). West London recorded 38.1°C (100.5°F), its hottest day of the year. The heat arrived on top of weeks with barely any rain across the region.
What makes peat fires especially difficult to manage is their below-surface behaviour. Ordinary forest fires burn through surface vegetation and can be attacked effectively with water-bombing aircraft. Peat fires burn in the organic layer beneath the surface. Aircraft water drops wet the top but do not penetrate to the smouldering layer below. Ground teams must work directly into the fire zone with hoses and hand tools to access and saturate the burning peat, a slow, physically exhausting, and potentially dangerous process.
Yernaux’s statement that conditions were “much deeper” than 2011 referred specifically to this subsurface burning. Karim Bouarfa, a fire brigade captain who worked through Saturday night on the High Fens fire, spoke of the scale in terms that Belgium’s firefighting community had not previously used: “Now, we have to face the facts.”
Scientists studying fire behaviour in Europe have consistently noted that human-caused climate change increases the likelihood of the hot, dry conditions that allow wildfires to spread faster and burn longer. The Belgium case is a specific illustration of that pattern applied to a northern European country that historically considered itself outside the zone of severe wildfire risk.
Belgium’s Fire in Context: Europe’s August 2026 Wildfire Wave Across Greece, Spain, and Germany
Belgium’s record wildfire on August 14-16 was one of multiple simultaneous major fires burning across Europe on August 16, 2026, with two people killed on the Greek island of Salamina near Athens, 16,600 hectares burned in Aragon, Spain, and Germany managing a separate wildfire in the Hürtgen Forest – a week in which firefighters from at least eight European nations were active in simultaneous fire emergencies across the continent.
On Salamina, the Greek island near Athens, a wildfire broke out on Sunday, August 16, in near gale-force wind conditions. The island had been placed at high wildfire risk in advance. Two people died. Firefighters deployed 260 personnel including 15 ground teams, 10 aircraft, and 8 helicopters.
In Aragon, northeastern Spain, a separate large fire had burned 16,600 hectares by August 16. French authorities sent 100 firefighters across the border to assist Spanish crews.
Germany was managing two fire-related situations simultaneously: firefighters from Germany and Luxembourg were assisting Belgian crews in the High Fens, while domestically, a wildfire in the Hürtgen Forest near the Dutch border had required the evacuation of approximately 2,000 residents of the town of Gey. By Saturday, German firefighters had achieved containment of the Hürtgen fire; Gey residents were allowed to return home on Sunday.
Belgium activated the EU Civil Protection Mechanism on Saturday, August 15, formally requesting EU emergency assistance. The European Union deployed 3 helicopters and 2 water-bombing aircraft from member states across Europe on the same day. Dutch helicopters arrived separately on Sunday. The EU mechanism’s rapid activation reflects how European fire emergency capacity has been developed since the catastrophic fire seasons of 2017 and 2022.
Three days before the Belgian fire started, on August 13-14, a wildfire near Omiš on Croatia’s Dalmatian coast burned 900 hectares, hospitalized 40 people, and forced 2,000 to evacuate in what fire chief Slavko Tucaković described as one of the worst in Croatia’s history.
| Country | Location | Scale | Status August 16 |
| Belgium | High Fens, Liège province | 3,000 ha; national record | Still burning; heading toward Germany |
| Greece | Salamina island, near Athens | Active | 2 killed; near gale-force winds |
| Spain | Aragon region | 16,600 ha burned | Active; French firefighters assisting |
| Germany | Hürtgen Forest | Active until Saturday | Contained; Gey residents returned |
Belgium Wildfire Emergency Response: 260 Firefighters, EU Aircraft, Dutch Helicopters, and the Army
Belgium’s emergency response to the High Fens wildfire assembled one of the largest combined firefighting operations the country has mounted, with 260 firefighters on site including 15 ground teams, 10 fixed-wing aircraft, and 8 helicopters, backed by the Belgian Army, farmers using agricultural equipment, firefighters from Germany and Luxembourg, Dutch helicopters from the Netherlands, and EU emergency reinforcements of 3 helicopters and 2 water-bombing aircraft.
Stephanie Ernoux, spokesperson for the government of Belgium’s Wallonia province, confirmed on Sunday that firefighters were focused on containing the advancing fire front rather than attempting total extinction. Containing the front means establishing control lines ahead of the fire to prevent further spread, buying time for aerial and ground teams to attack the body of the fire behind the front line.
Farmers joined the firefighting operation using agricultural sprayers and tractors to wet down vegetation ahead of the fire line and to cut firebreaks in the fields bordering the reserve. The combination of professional firefighters, military personnel, and farmers reflects the scale of an event that exceeded Belgium’s standard firefighting capacity from its first day.
Belgium triggered the EU Civil Protection Mechanism on Saturday after determining that the fire required resources beyond what Belgium and its neighbours could supply bilaterally. The EU response came within hours. Dutch helicopters arrived independently on Sunday, adding water-carrying capacity to the aerial fleet already operating over the High Fens.
Belgium Wildfire August 2026: A Record That Should Not Exist in Northern Europe
The Belgium wildfire of August 2026 broke the country’s historical record by more than double, in the same nature reserve, against the same type of peat bog ecosystem, under conditions of heat and drought that have become the signature of European summers in the 2020s. Karim Bouarfa, who worked through Saturday night battling the High Fens fire, said: “Now, we have to face the facts.” Three thousand hectares of protected peat bog have burned. Six hundred residents were evacuated. The German border is under smoke. The fire was still advancing as Europe entered August 16. For a country that had never considered itself in the zone of catastrophic wildfire risk, that reckoning is now underway.

Frequently Asked Questions
Where did the Belgium wildfire start and when?
The Belgium wildfire started on Friday, August 14, 2026, in the High Fens (Hautes Fagnes) nature reserve in Liège province, eastern Belgium, near the German border. By Sunday, August 16, it had burned 3,000 hectares and surpassed the previous national record set by a 2011 fire in the same reserve.
Is the Belgium wildfire the largest in the country’s history?
Yes. The High Fens wildfire of August 2026, at 3,000 hectares, is Belgium’s largest wildfire ever recorded, according to the European Forest Fire Information System. It more than doubled the previous national record, a 2011 fire in the same Hautes Fagnes reserve that burned 14 square kilometres.
Why did the Belgian wildfire spread so rapidly?
Belgium had received barely any rain for weeks before August 14. Temperatures reached 37°C the same day the fire started. The High Fens peat soil had dried to critical levels at depth. Peat fires burn below the surface and cannot be extinguished by aerial water-bombing alone, making containment far slower.
How many people were evacuated in the Belgium wildfire?
Six hundred residents in the municipalities of Waimes and Bütgenbach in Liège province were ordered to evacuate on Saturday, August 15. Germany’s town of Monschau, just across the Belgian border, also asked border residents to leave due to significant smoke pollution from the advancing fire.
What is the High Fens and why is its ecology significant?
The High Fens (Hautes Fagnes) is a protected Ardennes nature reserve containing rare raised peat bogs and wet heath habitats that take centuries to form. Peat stores more carbon per hectare than tropical forest. Burning 3,000 hectares of peat habitat releases centuries of stored carbon and creates ecological damage that cannot be restored quickly.
Did the Belgian wildfire cross into Germany?
German authorities said on August 16 the fire was not expected to cross into German territory, but significant smoke pollution prompted Monschau to ask border residents to evacuate as a precaution. German firefighters joined the containment effort inside Belgium. Germany was simultaneously managing a separate wildfire in the Hürtgen Forest.
What other major European wildfires were burning at the same time?
On August 16, 2026: two people died in a wildfire on the Greek island of Salamina near Athens; 16,600 hectares burned in Aragon, Spain, with 100 French firefighters deployed; Germany managed the Hürtgen Forest fire requiring 2,000 evacuations before containment; and Croatia’s Omiš wildfire had burned 900 hectares three days earlier.
