In order to establish those areas where forest fire management strategies should be implemented, it would be sufficient to identify those areas with a history of forest fires; however, because of the anthropogenic nature of the causes of the fires, the location of the areas may vary from one country to another. The objective of this work was to determine the spatial-temporal variations of fire occurrence through the estimation of the Kernel density as well as the parameters that favor it. Historical information (2016-2023) on forest fires in Colima, Mexico, was used. The areas with the highest priority for protection against forest fires were those with the highest density of occurrence. Their distance was analyzed in relation to risk parameters: (a) Roads, (b) Highways, (c) Agricultural areas, and (d) Grasslands. The results indicated that most of the forest fires were located in the Western region of the state, in areas with secondary vegetation of low deciduous forest. However, there was a temporal variation in the spatial distribution of fires, although it was conditioned by the proximity of access routes, mainly by the proximity of roads, with a negative trend (p<0.001). The highest number of fires was located at an altitudinal range of 0 to 1 650 m; while, in relation to the proximity of roads, the highest frequency occurred at an altitude of 0 to 820 m. The definition of priority areas, based on (Kernel) fire densities, makes it possible to locate and delimit areas by fire risk class.
