In the soil diverse organisms live that due its activity, can influence in the chemical, physical and
biological processes, contributing for fertility of the soil for the mineralization of nutrients contained
in the organic substance of the soil. The vision of the ecological restoration search always to
imitate the nature, where a set of techniques is implanted not in total area and yes in nuclei,
restituting the mosaic of the environment. The activities of restoration, based in the ecological
process of nucleation, had been called by Reis et. al. (2003) of ?nucleation techniques of
restoration?. The diversity of the flora has consequences in the diversity of the macrofauna of the
soil, that directly is influenced by the antropical action. This work had as objective to evaluate the
possible correlations between the macrofauna of the soil and the restoration of a demonstrative
unit (UD) of 1000m2 (0.1 ha) in an area of Atlantic Forest in Piranguçu ? Minas Gerais estate ?
Brazil. During the restoration, it was evaluated activity of the macrofauna of the soil, parallel the
restoration of the area. Samples of soil had been collected for chemical analysis, and used the
following Nucleation Techniques: tree branches transportation, in a continuous line of 1m3, soil
transportation removing a fraction of 5 cm of the soil, direct transposition of plantlent, and setting
of two dry perches (tree deceased). In order to evaluate the activity of the macrofauna throughout
the restoration process, traps had been installed (of fall) ?pitfall-traps? (Moldenke, 1994). For
such evaluation, 15 pots in rows, that had remained seven days in the field, that they had been
soon after conditioned for posterior identification. The samplings were taken along one year,
one to each station, autumn, winter, spring and summer. During of the period of collection
variations in the total number of captured individuals had been observed, resulting in 1197
pertaining individuals 11 Orders, being 251 in the autumn, 148 in the winter, 387 in spring and
411 in the summer. These variations had been attributed the climatic factors, and to the effect of
the restoration due to the successional processes that was initiated in the system by the
nucleadoras techniques. Although the restoration still is in the beginning, already all is noticed a
consequent interaction of the nucleadoras techniques, as decomposition of branches, burlap
formation, presence of anemochorous, autochorous, and zoochorous seeds, sprouting of
plantlent, presence of avifauna in the perches, biogenic presence of the macrofauna, and
structures (fecais galleries, pellets, etc.) that they modify the physical property of the soil where
they live and the availability of resources for other organisms Wolters (2000), in a process of
biodiversity nucleation.
