Resumo(s)
The aim of this study was to evaluate the effect of vegetation on soil microbial activity during
spontaneous restoration and the effect of remaining eucalypts on the restoration stage of reserve
ranges installed in eucalypt plantations. The studied areas were in the following stages: initial
restoration stage with and without remaining eucalypts; advanced restoration stage with and
without remaining eucalypts. Areas of Cerrado, native forest and commercial eucalypt plantation
(Eucalypts) were evaluated for reference. Principal component analysis detected the following
groups: 1- Cerrado and areas in initial restoration stage with or without eucalypts and areas
in advanced restoration stage without eucalypts; 2- areas in advanced restoration stage with
eucalypts; 3- native forest; 4- Eucalypts. The restoration areas are at intermediate stage of recovery,
slightly superior to the advanced stage. Basal respiration, organic and microbial soil carbon
and microbial and metabolic quotients were more similar to those observed in Cerrado than in
eucalypt cultivation areas and little influence of the remaining eucalypts plants was observed.
