By Franco Pedrotti

The ebook is worried mostly with geobotanical mapping. Geobotany is a wide technology that bargains with the examine of species and of crops groups in terms of the surroundings; it comprises different, possibly extra everyday sciences, akin to plant geography, plant ecology, and chorology, and phytosociology (plant sociology).
Geobotanical cartography is a box of thematic cartography that bargains with the translation and illustration, within the kind of maps, of these spatial and temporal phenomena that pertain to plant life, plants, vegetated landscapes, crops zones, and phytogeographical devices. The construction of a geobotanical map represents the final level in a cognitive method that starts with observations within the box and maintains with the gathering of pattern information, interpretation of the phenomena saw, and their acceptable cartographic illustration; geobotanical cartography is heavily tied to the ideas and scope of geobotany in general

Beyond scientific interest, current methods and trends in chorological mapping come today from conservation problems: knowledge of the locations of species is essential for protection, including establishment of protected areas. Chorological data are also essential for compilation of the “red books”, for whole countries or more regionally, and for evaluating plant biodiversity.

On this map it is possible to recognize seven synusiae (of order III, sensu Gams 1918) forming three groups: synusiae that occupy submerged depressions, flat terrain and small rises. ); the synusiae of flat terrain have only tall forbs; and the synusiae of the rises are characterized by Linnaea borealis, Vaccinium vitis-idaea, Majanthemum bifolium and other species (Falin´ski and Venanzoni 1991). e. a complex, multi-layered association defined during the integrated synusial analysis of the vegetation by integrating the different synusiae at a site (Gillet 1988).
