Qualidade física do solo das trilhas do parque estadual do Cerrado - PR

Abstract

The tourism in protected areas has been gaining attention and interest. However, the increased flow of people in these areas may endanger the ecological integrity of these environments preserved since the intensification of tourist crossing the tracks may enhance the possibility of soil compaction (soil degradation). This study aims to evaluate the effect of the movement of people in some soil physical properties of the State Park trails Cerrado (PR) to guide future actions in planning the use and occupation of the area that contribute to the preservation of the ecosystem. To evaluate the physical soil were collected at random points, 5 soil samples off track (FTr) and track (Tr) with preserved structure in the depth of 0-20 cm. With these samples, we determined the bulk density, total porosity, macro and micro, organic matter and aggregate stability. The trails of the state park Cerrado (PR) receiving more than 50 visitors over the month, showed no degradation as the organic matter content and soil aggregation in relation to the area of native soil.
