Land-use interactions with fire in Mediterranean Pinus halepensislandscapes of Greece: patterns of biodiversity

摘要

The landscapes of the Mediterranean have suffered major land-use transformations during the last 40 years. Fire, as an integral part of the Mediterranean environment has also experienced changes in its regime, mainly in its recurrent time. The aim of this paper is to tackle the influence of land-use interactions with fire on the patterns of plant diversity in Penteli mountainous region of Attica, Greece. Land cover maps for 1945, 1971 and 1995 were obtained from aerial photographs. The area has experienced several fire events, the two biggest and more recent with only 3 years difference. Sites studied are discriminated after their geological substrate, their post-fire age, the fire interval and the number of fires they have experienced. Land use history does not seem to affect sites ordination when data on vegetation composition are used.
