Mapping floristic diversity: a case study in Sicily
Keywords:Biodiversity, Plant species richness, Biological Conservation, Environmental planning, Grid mapping, Geographical Information Systems
This paper presents an operational methodology to map and analyze the floristic richness of “target species” in Natura 2000 sites, making use of G.I.S. tools and procedures. A Floristic diversity map (scale 1:50,000), covering an area of 612 km2, was produced by a team of experts as part of the management plans of “Madonie Mountains” Sites of Community Importance (SCIs), located in Sicily (Italy). The primary grid map represents the richness of “target species”, which include species of Community interests, taxa on the National Red List, endemic and threatened, species protected under International Conventions, taxa of phytogeographic importance. Secondary data frames include a three-dimensional map representing the number of species present in each cell, a coarser species richness distribution (scale 1:400,000) and a reference map of endemism rate in the Mediterranean area. Such a cartographic document has proven to be an effective tool in biodiversity conservation planning. Furthermore, the knowledge of floristic richness and distribution is not only important for the management of protected areas, but it is also important for the sustainable management of cultural landscapes.
