Dear Editor,rnThe forests of the world are prone to fires of varying frequencies and intensities (Whitlock, 2004).After fires,habitats previously not present in forest emerge: these are the areas of bare ground that are better insulated and thus have more contrasting soil temperatures during the day and between seasons (Winter et al., 1980;Phillips et al., 2000).Such areas are usually more poorly drained due to the lack of trees providing evapotranspiration (Smits et al., 2016).Moreover, soils in the bt areas become a source of easily available nutrients (N, K, and P) (Certini, 2005).These factors lead to an instant increase of microbial biomass and rapid development of pyrogenic plant communities.
