• Abstract: Mining, although important for job creation and investments in health and education, has significant environmental impacts, such as deforestation and soil degradation, altering the landscape and affecting the habitats of soil organisms. This study aimed to characterize the activity of epigean fauna in areas reforested after bauxite mining in the municipality of Juruti, western Pará, using different nucleation methods. Four areas were selected: (A1) reforested in 2018, (A2) in 2015, (A3) in 2012 and (A4) a native forest as a reference. Pitfall traps were used to collect epigean fauna. The traps remained in the field for 5 days, composed of 70% alcohol and neutral detergent to preserve the organisms. The activity of the epigean fauna was expressed by calculating the number of individuals per trap per day. The activity of the groups Araneae, Acari, Blattodea, Diplopoda, Heteroptera, Hymenoptera and Isoptera were similar in the evaluated areas. The Entomobryomorpha group was observed to be more active in area A4, to the detriment of the areas with nucleation techniques. While the Formicidae did not present differences in areas A2, A1 and A4. The reforested areas promoted the addition of plant material, especially brushwood, which favored the activity of the epigean fauna groups.
