Abstract

The State of Parana has suffered severe degradation of its native forests, and the Semidecidual Seasonal Forest has been the most affected forest type. This degradation caused forest fragmentation with great damage to biodiversity and environmental balance. This study aimed to acknowledge the environmental perception of the pioneer people that were present by the time of the forests degradation, and to evaluate the quantity and quality of remaining forest areas in the Maringa municipality between1990 and 2008. The more adequate satellite images Landsat 5 to the referred years were selected, prepared through georeferencing and segmentation for a supervised classification and calculation of landscape indexes. In order to qualify the area the methodology used evaluated its physical and biological attributes. It was noticed that the overall perception of the pioneer people about the native forests is based on an superficial knowledge, where remains the idea that native forests hinder economic development. It was also noticed an increase in forest coverage in the municipality of about 70%, mainly concentrated along the rivers, mainly located in the southern rural sector of the city. The forest fragments with better flora quality and greater richness of species were those located in the northern sector of Maringa.
