One crew from Amersham, one crew from Beaconsfield, a wildfire response unit from Chesham and one crew from Hemel Hempstead attended a fire in a field.
To gain access to the affected area, firefighters cut through a barbed wire fence.
Firefighters tackled a grass fire affecting approximately 10 acres of land, with around 40% of the field damaged by fire.
Crews used one hose reel jet, a wildfire response unit and beaters to extinguish the fire and prevent it from spreading further.
Crews remained on scene for a considerable time to ensure all hotspots were fully extinguished.
