Peat is Highly Flammable
The New Forest includes large areas of peat, which can ignite very easily and burn for days or weeks, even smouldering underground and re-emerging away from the initial source. These fires are incredibly difficult to extinguish and highly unpredictable. Temperatures in a disposable barbecue can reach over 600°F and placing them directly on or close to the ground can cause peat to alight.
