The current climate change in which we are immersed favors both the increase in the entry of invasive alien species (IAS) and the frequency and intensity of forest fires. The northwest of the Iberian Peninsula is one of the areas in Spain with the highest number of fires. Fires open spaces free of competition which are quickly exploited by many invasive species to establish themselves in new places. In addition, fire can also act directly by stimulating the germination of some of these invasive species. In the invasion process of a species, three phases are usually distinguished: Introduction, Establishment and Invasion. The greatest IAS control efforts should be concentrated in the first two stages. Among the many IAS that are already part of the landscape of Galicia, the species of Acacia are a particularly dangerous group for native vegetation for their ability to produce large amounts of seeds, form soil seeds banks lasting for many years, stimulation of germination by the heat of the fires and capacity of regrowth, among other strategies. Its control can be a difficult, complex and extensive task in time. Among other measures, autochthonous, highly colonizing species, could be used to eliminate IAS by competition.
