Thermal Drones Used to Detect Underground Wildfire Hot Spots in the Cairngorms

Thermal-equipped drones are used to locate residual hot spots after a major wildfire in the Cairngorms, Scotland, and to support long-term landscape monitoring. The footage follows drone teams, land managers, and rangers as they survey scorched forest, identify heat signatures beneath the soil, and report findings for firefighting crews.

■ Thermal drone response to a large wildfire
- Why ground crews needed aerial thermal coverage
- How drone teams supplied information to agencies

■ Detecting underground hot spots
- Pre-sunrise surveys and visual line-of-sight roles
- Identifying warm soil, smoke, and heat signatures
- Reporting locations to land managers for follow-up

■ Monitoring ecosystem recovery
- Repeated waypoint flights to track change over time
- Observing early signs of life in damp fire-break pockets
- Use of drones after active hot spots are gone

The material is suited to viewers interested in wildfire management, drone technology, environmental monitoring, and climate-related emergency response. It provides a concise look at how thermal imaging can reveal hazards that are invisible to the naked eye and how repeated aerial surveys can contribute to recovery monitoring.
