Let me make it clear that burning takes place only in February and March, when the weather is cold and wet, and therefore by extension so is the heather—hence why it is called a “cool-burn”. Trained operatives burn the heather in a light wind. A Scottish moorland group made a video of a heather burn moving slowly over a Mars bar. Five minutes later, once the fire had passed, the Mars bar was picked up and opened. The fire had not even melted the outer chocolate coating. As well as leaving the Mars bar unharmed, the process leaves the peat unharmed, and any damage to the moss and litter layer, which sits on top, is minimised.
