ResumenWildfires are one of the most important problems that the planning and management of forest areas in Andalusia face. Although the number of fires and total burnt area experience significant fluctuations from year to year, there is a spatial pattern resulting from the interaction between anthropogenic and environmental factors which determines the existence of more vulnerable areas. In this communication, we present an exploratory study in which we analysed the characteristics of areas that been burnt by wildfires in Andalusia from 1975 to 2013 in relation to different explanatory variables. This study is part of a larger project which aims to model the general explanatory mechanisms underlying the distribution of burnt areas in the south of the Iberian Peninsula. To do this, we developed a spatial database which annually recorded the burnt areas in the whole region. Based on previous studies, we identified the main factors potentially involved in the distribution of forest fires. We selected a set of environmental variables that we coded as cartographic covers. Finally, we performed a cross-tabulation analysis by relating the burnt areas to environmental and territorial factors. The results show that most wildfires in Andalusia occurred in shrublands, in low and middle mountain areas, and in areas with moderate to high slope. The provinces with the largest average burnt areas were Huelva and Malaga, which were also the provinces with the highest frequency of burnt areas.
