Abstract

[Autom. eng. transl.] The Interreg project MANFRED (www.manfredproject.eu, 2009-2012) aimed to study the impacts of climate change on the health status of Alpine forests. Within the project, an activity line was dedicated to the study of space-time dynamics of forest fires in the Alps. On an alpine scale, the effectiveness and efficiency of the fire hazard forecasting services, of the activities of risk prevention and anti-fire actions has significantly increased over the past few decades. The current trends show a progressive reduction in both the frequency of fires and the average extension of each occurrence. Despite this, forest fires are one of the main pressure factors for the forests of the Alps. According to data from the pan-alpine fire database developed in the project (and can be consulted via the dedicated webGIS platform), in fact, in the period 2000 - 2009 they were recorded over 29,000 forest fires, with a total burned area of almost 95,000 ha. Furthermore, the current climate changes could represent a determining factor in influencing future patterns of fires and the fires regime itself. The present work was aimed at a characterization of spatio-temporal patterns of fires in the Alps, with the aim of defining which vegetation units are most critical both in terms of frequency and average extension of the fires that develop within them. For this purpose, a Monte Carlo analysis was conducted on a sample of over 26,000 fires, stratified according to various parameters: location of the trigger point, geographical area, season, altitude, exposure. The analysis highlights the most vulnerable vegetation units with respect to the fire risk and provides a first knowledge base to guide future risks prevention and mitigation actions related to forest fires in the Alps.
