How drones are hunting fires hidden beneath the Cairngorms
Thermal drones are being used to detect and map hidden hot spots of a wildfire that devastated the Cairngorms National Park in July, allowing ground teams to extinguish them efficiently.

Following a major wildfire in Scotland's Cairngorms National Park, thermal drones are now crucial for identifying lingering underground heat sources. This technology enables targeted intervention by conservation teams, preventing reignition and aiding in the long-term monitoring of the landscape's recovery.
Imagine a campfire that's been put out, but the ground is still warm underneath. Drones with special cameras can see this hidden warmth, like a superhero's heat vision. This helps people find and cool down those warm spots before they start a new fire, helping the forest heal.
Analysis
Cairngorms National Park
The Cairngorms National Park, a vast area in Scotland, was the site of a significant wildfire in July that burned across approximately 3,300 hectares. The immediate aftermath saw the deployment of experienced drone pilots to provide aerial intelligence to firefighting agencies. However, the challenge has evolved from combating visible flames to detecting persistent heat sources that remain buried beneath the ground. These 'hidden fires' pose a continuous threat of reignition, making their precise location critical for effective management.
Pete Short
Drone pilot Pete Short has been instrumental in this post-fire effort, conducting dawn patrols for nearly three months. His work involves launching thermal drones to scan the landscape for heat signatures. The technology allows him to identify areas where the ground remains dangerously hot, even when no visible smoke or flames are present. Pete describes the initial firefighting as one of the most challenging environments he has encountered, but the current task of finding these subtle hot spots requires a different, yet equally vital, skill set. His findings are reported to land managers, enabling focused efforts to extinguish these lingering embers.
Thermal Drones
The core of this operation relies on thermal drones, which can detect heat invisible to the human eye. These drones provide real-time imagery, highlighting 'hot spots' beneath the surface. This technology is indispensable, as Pete Short states, "Without the thermal technology we would be totally blind to this." The data collected allows conservationists, like Ben Jones from the RSPB, to deploy limited resources precisely where they are needed most, ensuring that teams can efficiently dig into the ground and douse the remaining heat. Beyond immediate fire suppression, these drones are also being programmed for long-term monitoring, flying predetermined routes to document the landscape's recovery over time.
Key points
- Thermal drones are detecting hidden underground hot spots from a July wildfire in the Cairngorms National Park.
- This technology allows for precise targeting of limited ground resources to extinguish lingering heat.
- Drone pilots like Pete Short are crucial in identifying these invisible threats.
- The drones are also being used to monitor the long-term ecological recovery of the landscape.
- This AI-driven approach enhances wildfire management and conservation efforts.
The successful use of thermal drones in detecting and managing post-wildfire hot spots could lead to more efficient and less resource-intensive firefighting strategies. This technology's application in monitoring landscape recovery also promises valuable data for understanding ecological resilience and informing future conservation efforts.
Despite the effectiveness of thermal drones, the persistent nature of underground fires means that complete eradication remains a challenge. There's a risk that some hot spots could be missed, leading to reignition and further damage to the already fragile ecosystem, especially if resources for follow-up ground operations are insufficient.
