Over the last years there have been several large wildfires in Norwegian coastal heathlands and nearby forests, some occurring in dry winters with strong winds and others due to high temperatures combined with low precipitation [1]. Wildfire risk depends on many factors, such as temperature, wind conditions, humidity, and characteristics of the vegetation, including chemical composition and geometry. In this study, the fire characteristics of stair-step moss (Hylocomium splendens), lingonberry shrub (Vaccinium vitis-idaea), juniper (Juniperus communis), bilberry (Vaccinium myrtillus) leaves and stem, and heather (Calluna vulgaris) were studied.
