This study analyses the postglacial fire history in a temperate mountain forest in Central Europe. More frequent fire dis- turbances were related to coniferous forests dominated by Pinus sylvestris/mugo during the period 11 200–9300 cal a BP and the subsequent expansion phase of Picea abies between 9300 and 6200 cal a BP. The fire disturbance dynamics closely resembled those of boreal forests, with fire occurring with a frequency of one to two fires per 500 years during the early to mid-Holocene. By contrast, from 6200 to 600 cal a BP, fire completely disappeared from mesic sites. This marked decrease was probably a response to climatic cooling around 5300–5600 cal a BP, which triggered an expansion of less-flammable mixed deciduous forests consisting of Fagus sylvatica and Abies alba. This suggests that climatic factors acted synergistically with biotic change, resulting in a modulation of the local fire regime. These results highlight the importance of fire disturbances for forest communities in Central Europe, especially for coniferous forests.
