Physiognomic-ecological units associated with remnants of natural vegetal cover


Georeferenced maps will be drawn containing the potential vegetation according to the physiognomic-ecological units (types of vegetation) developed by the RADAMBRASIL project. This survey will be associated with the São Paulo Forestry Inventory (1993) developed on the scale 1:50.000, with the mapping and quantification of the remaining natural vegetation and the states of forest cultivation (reforestation), correctly updated using recent orbital images. The phytophysiognomies considered in that opportunity (forest, scrub, wooded savanna, barren land, enclosed countryside, open countryside, cultivated plains, mangrove and sandbank), will be detailed within the concept of the physiognomical-ecological units of the aforementioned Project. In the case of the cultivated forests, it will be possible to undertake studies on the implantation of these forests in spaces previously occupied by natural ecosystems. The updating of the survey of the natural vegetation, based on the São Paulo Forestry Inventory (1993) and the elaboration of the respective georeferenced digital base, are already objectives of the Biota-FAPESP Program, specifically FAPESP Project 98/05251-0 (Viability of Conservation of Remaining Fragments of Cerrado in São Paulo) and FAPESP 98/05117-1 (Development of an Environmental Information System for the Biota-FAPESP Program).
