Soil Fauna Helping the Recovery of Degraded Areas in Corrego Brejauba, State of Minas Gerais, Brazil

ABSTRACT

Two areas were chosen in Corrego Brejauba, State of Minas Gerais in order to characterize soil and litter invertebrates: a secondary forest and an area in advanced stage of degradation. Invertebrates were extracted by sorting and Berlesse funnels. The abundance and richness were higher in the secondary forest. In the degraded environment, lack of vegetation cover probably resulted in smaller sampling of soil fauna. Key groups such as Colembolla, Oligochaeta and Mites, involved in the soil-litter fundamental processes, can help the recovery of degraded areas through strategies that encourage their activities.
