Abstract

Postfire regeneration of thermomediterranean shrublands burnt in 1998 was studied in the Province of Murcia (SE Spain). The vegetation structure of sites with different exposures was compared with that of adjacent unburnt areas. Three years after the fire, the mean vegetation cover of the burnt sites was still significantly lower than that of the non-burnt areas. However, the results of a Detrended Correspondence Analysis indicate that fires induce only minor changes in the species composition and the vegetation structure. Fire seems to be a common phenomenon, and the dominant species are characterized by pre-adaptations to withstand fires. The most frequent pre-adaptation is the ability to resprout rapidly from subterranean parts, whereas the regeneration from seeds is clearly less important in the most dominant species.
