Fire is a natural phenomenon that has played a critical role in transforming the environment and maintaining biodiversity at a global scale. However, the plants in some habitats have not developed strategies for recovery from fire or have not adapted to the changes taking place in their fire regimes. Maps showing ecological vulnerability to fires could contribute to environmental management policies in the face of global change scenarios. The main objective of this work is to characterize the ecological vulnerability to fires based on how fires occur on a global scale. For this purpose, we are going to create zonal statistics by biome and by vulnerability category, finding out the average data of the different fire variables. For this, we have taken two spatial databases previously developed by us, Ecological Vulnerability to Wildfires and Wildfires Characteristics. Ecological Vulnerability to Wildfires is a global database that categorizes spatial vulnerability by ecoregion. Wildfire Characteristics collects global spatial mean data on recurrence, seasonality, patch size, and interannual variability. The results show that in areas with High/Very High vulnerability of tropical and subtropical biomes, fires are not very intense, with a small patch size and low interannual variability, but are highly recurrent and with extensive seasonality. The most vulnerable areas of the Mediterranean biome have more intense fires, with a considerable patch size and, in addition, they present considerable interannual variability, little recurrence and limited seasonality. Temperate forest biomes present their most vulnerable areas with moderate intensity, patch size and recurrence fires, but with high interannual variability. The most vulnerable areas of the montane grasslands biome show highly recurrent fires, with extensive seasonality, with moderate patch size, intensity, and interannual variability.

This congress will take place in November 2022. In addition, this work will be a book chapter.
