Mapping of forest fragments in the Aeronautics Garrison of Pirassununga (São Paulo State, Brazil)
| Resumo: | The remaining forest in the State of São Paulo is fragmented and has an accelerated process of devastation, as well as the maintenance of forest fragments is essential for the conservation of biodiversity. Therefore, this work was understood as a forest analysis of the forest, through forest mapping and located in Aeronautics Garrison located in Pirassununga (SP), Garrison on the banks from Mogi Guaçu River (SP). Forest fragments in Garrison are essential for the conservation of biodiversity, since they present ecotones with different plant forms. Classification and measurement from tree component was carried out through field visits and the use from free QGIS 2.18 software, through which it was also possible to perform the examination of Landsat 8 satellite images, and the calculation of vegetation indices by difference normalized (NDVI) and shaped (SI). From this study, approximately 2000 hectares of native vegetation were identified, considering formations as Seasonal Semideciduous Forest (FES) associated with the Riparian Forest, Cerrado and Cerradão, and transition areas, in addition to the 252 hectares of lowland and 356 hectares of silviculture . From municipalities belonging to the Water Resources Management Unit of the Mogi Guaçu River Basin, Pirassununga has fragments FES and Cerradão, with an area greater than 200 hectares, which has not yet been accounted for in the literature. And by using the NDVI it can be seen that in the summer the vegetation was denser and that in the winter there is a reduction in these values due to the decrease in leaf biomass. |
