About

Civil defense or civil protection is an effort to protect the citizens of a state from human-made and natural disasters. It uses the principles of emergency management: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew.

About

A wildfire, forest fire, brushfire or a bushfire is an unplanned and uncontrolled fire in an area of combustible vegetation. Some natural forest ecosystems depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. Controlled burns can turn into wildfires if they escape containment lines.

began around midday on Friday 14 August and expanded rapidly from an early estimate of 80 hectares to about 850 and then roughly 3,000 hectares, according to the Walloon public service figure reported by RTBF. Around 600 residents in Waimes and Bütgenbach were ordered to evacuate. Some evacuees were sheltered in a Malmedy sports hall, while some residents reportedly declined to leave.

near the German border. By Sunday afternoon the fronts at Jalhay and Monschau were described as under control, but the overall fire was still not mastered. A fire line of about one kilometre was advancing south-east towards the Ternell nature site.

The difficult, uneven terrain prevents crews from attacking every part of the fire at close range with their usual equipment. Peat can also retain heat below the surface and create hidden hot spots after visible flames subside. Monday's weather was expected to risk complicating the work further.

Access restrictions remain part of the response. The N68 route onto the High Fens plateau was closed to the public so emergency vehicles could work, and smoke was reported as far as Namur Province. Tourism businesses and events across the affected area faced evacuations, closures, cancellations and early departures during the normally important 15 August weekend. Activities on Lake Robertville were restricted so firefighting aircraft could take on water.

The immediate priorities remain protecting residents and responders, containing the advancing perimeter and preventing underground hot spots from reigniting. A reliable ecological assessment can only follow once the emergency is controlled.

Context & what happens next

What to watch

Watch for official confirmation that the perimeter is contained, revisions to the provisional affected area, any evacuation or smoke-health instructions, the lifting or extension of access closures, and an investigator’s finding on ignition. A later habitat survey will be more informative than early images about ecological severity.

What to do

Residents and visitors should avoid the High Fens, respect the N68 and local access closures, and keep emergency routes clear. Follow instructions from Liège Province, local municipalities, police and fire services rather than unofficial perimeter maps. Anyone seeing a new fire should call 112, provide a precise location and move away. People affected by smoke should close windows and seek medical advice if symptoms develop. Travellers should confirm accommodation, attraction and event status directly before setting out.

Impact

Regional — Evacuation orders affected communities in Waimes and Bütgenbach, while Malmedy provided emergency shelter. The public closure of the N68 and restrictions around the plateau are intended to preserve access for responders. Smoke has travelled towards Namur Province. Tourism operators reported evacuations and early departures, and events in Stavelot, Spa and Malmedy were cancelled or put under review; Lake Robertville activities were restricted for firefighting water operations.

How we got here

  1. 2011-04-25

    A major High Fens fire affected approximately 1,200 hectares, according to a Walloon government communication.

  2. 2023-05-29

    A new High Fens wildfire began; later assessments put the crossed area at about 155 hectares.

  3. 2026-04-23

    Wallonia raised the red flag in the reserve because of elevated nature-fire danger.

  4. 2026-05-04

    Wallonia lifted that red flag after rainfall reduced the immediate danger.

  5. 2026-08-14

    A wildfire spread through the High Fens and Liège provincial authorities activated the provincial emergency plan.

Voices & reactions

What the main actors are doing

Reported positions, summarised — not direct quotations

Firefighters and emergency coordinators

Their immediate priority is to contain the perimeter, protect crews and nearby communities, and identify underground hot spots that could reignite. Liège Province is coordinating the response under the provincial emergency plan.

High Fens reserve and environmental managers

Their focus extends beyond visible flames to damage in peat, heath and woodland habitats. A reliable ecological assessment can begin only after the fire line is stable and the affected area can be mapped.

Residents and visitors

They need clear information about smoke, access restrictions and emergency routes. Current guidance is to avoid the affected reserve, keep access roads clear and follow official instructions rather than unofficial perimeter maps.
