LANDSCAPE ANALYSIS OF A BUFFER ZONE TO PLANNING AND MANAGEMENT OF PROTECTED AREAS

The main objectives of this study were to diagnose the current environmental scenery and a legal scenery for the Buffer Zone (BZ) of the State Park of Porto Ferreira (SPPF), and propose a discussion of BZs and their planning. We conducted a mapping of the land use and occupation and calculated landscape metrics. The predominant class use in the BZ was sugarcane, with 46.24%, and forest class was the third, with the largest coverage, 12.7%. Landscape metrics indicated that the natural vegetation of the BZ has 83.3% of fragments up to 10ha, and 50% of them showed a very low connectivity. The PPA totalized 386ha, 39% of it has natural vegetation. As for the legal scenery, with all the PPA preserved, there would be an increase of 239ha of natural vegetation and a reduction of fragments from 60 to 27, thus showing larger and more connected fragments. The low percentage of forest, low connectivity between fragments and the non-compliance with environmental legislation in the BZ contribute to isolation of the conservation unit and the increase of edge effects, generating impacts on the biodiversity of the SPPF.
