Firefighters acted swiftly to wet down a smouldering tree stump as temperatures soared on Monday.
Two crews from Hemel Hempstead and Tring rushed to the B4506 - close to Ashridge Golf Course - to deal with the fire just before 1pm.
They used a hose reel to ensure the flames were extinguished and left just before 1.30pm. It is not known how the fire started but it was logged by firefighters as doubtful or deliberate.
