摘要：Regarding the protection and rehabilitation of forest fragments, Environmental Protection Areas (EPA) has been created. These EPAs are large areas with different kinds of human settlement, in order to protect biological diversity, to regulate the settlement and to ensure the natural resources sustainability. In some cases, the EPA is impacted by tourism, due to its natural attraction. Therefore, this research aims to assess the impact on the trails in the southern part of Cairuçu EPA. Soil samples have been collected to determine aggregate stability at six sites of Laranjeiras-Sono trail; three on the trail and three on the forest, at one depth (0-10cm). Analyses of water aggregate stability and sieve analysis, and realized that the forest areas are less degraded than the trail, where you can observe many erosive processes such as the formation of rills. Were performed analyses of water aggregate stability and granulometric analysis, and it was noticed that the forest areas are less degraded than the trail, where you can observe many erosive processes such as the formation of rills.
