Morocco, as a country with arid and semi-arid climate is vulnerable to climate change and presents many challenges for the future of the forest resources, mainly their vulnerability to forest fires. In addition, Moroccan forests are extremely flammable, especially in summer when the water content of plants, soil and the air become very low. This is especially noticeable in the Rif region (North of Morocco) where almost 65% of the phenomenon of wildfires across the country are concentrated. To deal with this new situation, the development of a prevention plan against forest fires requires an appropriate analysis of forest fire phenomenon and its response to the climate and vegetation changes. The present study has the goal to establish a spatio-temporal analysis of fires based on bioclimatic types because of the inclusive relationship between vegetation and climate. The fires that occurred in the rif region between 1997-2011 were analyzed and classified according to the affected area during the fire episode. The analysis has shown that almost 80% of the burnt area during the year were recorded only during August and September. Thereafter, using a two-factor ANOVA showed a significant difference of the fires spatial distribution according to the bioclimatic types, mainly for the warm variant of bioclimatic type where the development of the biomass is very important.
