Percolation in real Wildfires

This paper focuses on the statistical properties of wild-land fires and, in particular, investigates if spread dynamics relates to simple invasion model. The fractal dimension and lacunarity of three fire scars classified from satellite imagery are analysed. Results indicate that the burned clusters behave similarly to percolation clusters on boundaries and look more dense in their core. We show that Dynamical Percolation reproduces this behaviour and can help to describe the fire evolution. By mapping fire dynamics onto the percolation models the strategies for fire control might be improved.Comment: 8 pages, 3 figures, epl sytle (epl.cls included

Le formazioni erbacee del retroduna del Parco Nazionale del Circeo

The wet meadows and saltmarsh communities behind the dunes of the Circeo National Park (Latium, Centra Italy) are described. They make a complex, high-diversity mosaic in which floristic and vegetational elements, otherwise rare along the latial shoreline, can still be found

Ecosystem classification and mapping: a proposal for italian landscapes

This paper deals with the development of a hierarchical land classification for describing and mapping landscapes at different scales. After a brief overview of the theoretical background, an integrative framework is proposed which incorporates different hierarchical levels from plant sociology as diagnostic attributes. The feasibility of this proposal has been tested in different sample landscapes in central Italy. This system has a potential for applications to Italian landscapes from national to local scales, because it is based on solid theory and on information which is generally available in Italy
