Brasília - A field survey that took four years to complete showed that, beyond what was already known from existing forests in the state of Santa Catarina, other 4% of the territory of Santa Catarina are also covered by forests that are regenerating. The collection and analysis of data in the state functioned as an experimental project that is now extended to the whole country.
The expectation is that by 2016, all detailed information of the Brazilian forests, as the volume of land cover, soil quality, species of trees, animals and flora are related in a national inventory. With this kind of material scrutiny will be possible to rethink public policies that today are geared towards biodiversity conservation and economic use of these areas, but they were prepared with inaccurate information.
The Floristic Inventory of Forest Santa Catarina was made between 2007 and 2011 by the Brazilian Forest Service, Foundation for Research and Innovation in the State of Santa Catarina (Fapesc), Federal University of Santa Catarina, Enterprise for Agricultural Research and Rural Extension of Santa Catarina (Epagri), Regional University of Blumenau (Furb) and government of Santa Catarina.
In the case of Santa Catarina, previous data, detected by satellites, indicated that the remaining forest cover in Santa Catarina reached 29% of the territory. But when examined in person areas, the researchers found that there pioneer vegetation and forest formations in early stages of regeneration in another 2% to 4% of the territory of Santa Catarina.
"Normally personnel vegetation maps using satellite images and this has two problems. One is the pixel size [distance of points identified in the images], which is relatively large, and another when the vegetation is fragmented into small areas of forest does not enter into the account, "said Daniel Piotto, executive manager of Forestry Information Service Brazilian Forest.
According Piotto, inventory done in the field allows for the observation of these smaller areas. "The forests regenerate quickly. Areas that have been deforested or used prior to planting soybeans or corn and were abandoned regenerate in five years. In mapping we had before did not include many of these areas, "he added.
