ABSTRACT
The objective of this study map the landuse/landcover using IKONOS II data, automatize the delineation of permanent preservation areas and to identify landuse conflict based on the Brazilian Forest Code and Resolution nº 303 of CONAMA. The study was developed in the Alegre river watershed, located in the south region of the State of Espirito Santo, Brazil. Twelve landuse classes were mapped, along with the following permanent preservation areas: upper third of hills (49,7 ha); hillsides with slopes above 45 degrees (27,5 ha); springs and their respective contributing areas (1.975,6 ha); riparian zones with width less than 10 meters (2.818,3 ha); and upper third of sub-basins (4.695,8 ha), summing 9.566,9 ha (45.95%). The area of undue use corresponded to 7.499,7 ha (43,80%), with coffee plantation and pasture classes occupying most of this area (74.73%). Only 1.780,7 ha (18.61%) of permanent preservation areas are protected by native vegetation 7.786,2 ha (81.39%).
