Fire is a natural phenomenon that has played, on a global scale, one of the most critical roles in transforming the environment and maintaining biodiversity. However, some habitats have not developed plant strategies in the event of fires or are not adapted to the change in fire-regimes. The main objective of this study is to assess and map ecological vulnerability to fires on a global scale. Through existing global databases, Ecological Value and Post-fire Regeneration Delays indices have been generated. Two ecological indices have been identified for Ecological Value (fig. 1): Biological Distinction (fig. 2) and Conservation Status (fig. 3). For the Post-fire Regeneration Delay (fig. 4), the Adaptation to Fire (fig. 5) (result of integrated the type of fire-regime and its degradation) and Potential Soil Erosion (fig. 6) have been taken into account. The indices have been integrated into the Ecological Vulnerability to Fire (fig. 7) through a qualitative cross-tabulation. The results that show the world land surface are liable to lose their ecological value by 50%. The terrestrial biomes most affected are the moist tropical and subtropical forests; tropical and subtropical grasslands, savannas, and scrublands; and xerophilous scrublands. The latter mentioned is an attempt to produce a global fire hazard map, based on a wide variety of factors related to fire damage on ecological values. It can serve as an incentive to develop studies that can contribute management policies to global change scenarios.
