The objective of this work was to characterize the fauna of edaphic invertebrates in areas with distinct vegetation cover and land use. Three areas of the Ifes Campus of Alegre were sampled: 1 - coffee monoculture (MC); 2 - area under-recovery with the planting of native species and (FP); 3 - an area with native forest fragment (FES). Invertebrates were captured using pitfall traps containing formaldehyde solution (2%). Three samples were taken 30 days apart, from March to May 2015. In each sample, 5 traps were arranged in rows 10 m apart. Ecological indices were estimated for each area. By using multivariate statistical analysis, the areas were compared in relation to the occurrence of invertebrates. There was greater diversity in areas with greater plant diversity as well as better distribution of organisms in terms of trophic level. The study showed that the conserved FES area presented greater ecological balance in relation to the others. There is a need to adopt soil conservation practices in the coffee-growing area.
