Thermal Drones Monitor Lingering Wildfire Hotspots in Cairngorms National Park
Three months after a significant wildfire burned approximately 3,300 hectares of land in Cairngorms National Park, thermal drone technology is being deployed to locate persistent underground hotspots. While the surface flames have been extinguished, heat remains trapped beneath the soil, posing a risk of reignition. Drone pilots are conducting regular patrols to guide ground teams to these specific locations for targeted dousing. Beyond immediate fire suppression, the drones are being utilized to monitor the long-term ecological recovery of the landscape through repetitive, standardized flight paths.
Key points
- Thermal drones are identifying underground hotspots in the Cairngorms three months after a major July wildfire.
- The wildfire affected approximately 3,300 hectares of land.
- Ground teams use drone-identified coordinates to target and extinguish hidden fires.
- Drones are now being programmed for long-term ecological monitoring of the park's recovery.
- Experts note that while some recovery is visible, the full ecological impact may take years or decades to manifest.
What happened
Thermal drone technology is currently being used to detect persistent underground hotspots in Cairngorms National Park. The park was previously impacted by a large wildfire that began in mid-July and scorched approximately 3,300 hectares of land.
Although surface flames have been extinguished, drone pilots continue to conduct dawn patrols to identify heat signatures beneath the earth. These findings are reported to land managers, who deploy teams to dig into the soil and douse the heat sources with water.
Context
Ben Jones, a senior site manager for the RSPB at Abernethy, stated that the technology is essential for resource management, as it allows teams to focus their efforts on specific areas rather than searching the entire site. Despite the arrival of colder, wetter weather, officials warn that these hotspots retain the potential to trigger larger fires.
The park is also beginning to show signs of ecological recovery, with green shoots and fungi appearing on the scorched forest floor. Dr. Sarah Henshall of the Cairngorms National Park Authority noted that while the park will recover, the timeline for this process remains uncertain.
What's next
Conservationists are transitioning the drone technology toward long-term monitoring. By flying predetermined, repetitive routes, the drones will capture consistent visual data to track how the landscape changes over months and years.
Additionally, there is potential for this technology to be used for early detection of future wildfires, allowing for intervention before fires spread beyond control.
Why it matters
The use of thermal drone technology demonstrates a shift in wildfire management and ecological monitoring, allowing for precise intervention in hidden fire threats and providing a standardized method for tracking environmental recovery in protected landscapes.
What we know
- A wildfire in Cairngorms National Park burned approximately 3,300 hectares of land starting in July.
- Thermal drones are being used to detect underground hotspots three months after the initial fire.
