The human action has led to a sharp and accelerated environmental degradation of areas of permanent preservation (APP). In this context, the objective of this study was to identify and map the possible use conflicts in APPs of the Ribeirão Gustavo watershed, city of Massaranduba, SC. The analysis of the current use required QuickBird high-resolution satellite imagery with orthorectification from the year 2008, with confirmation of the
use classes and field occupancy. The following mapping classes were identified: reforestation, flooded rice, banana, fields, annual crops, subsistence household complex, agroforestry system, in addition to categories based on the CONAMA Resolution number 10 (Brazil, 1993): primary forest and secondary forest at initial, intermediate and advanced stages of regeneration. PPAs were mapped using SIG ArcGIS 9.3, considering the
limits set by law (Law 4.771/65 and CONAMA Resolution 303/02). Among the possible categories of APPs foreseen by legislation, the following were identified and mapped in the watershed at the banks of watercourses, buffer of 30 m: springs, buffer of 50 m: hilltops, through the delimitation of the upper third. The predominant land use of the watershed is forest, which represents 66.38% of the study area. APPs represent 660.35 ha, which corresponds to approximately 22.72% of the total area of the Ribeirão Gustavo watershed. Of this total, 80.32% of APPs are covered by primary and secondary forests, showing the high conservation level of the area. In the riparian forest, flooded rice is the culture causing the highest environmental degradation in the watershed.
