BRACATINGA (MIMOSA SCABRELLA), EUCALlPTO (EUCALYPTUS VIMINALIS) E PINUS (PINUS TAEOA) NA RECUPERAÇÃO DA BIODIVERSIDADE, A NÍVEL MICROBIOLÓGICO, DE SOLOS DEGRADADOS

Soil studied, comparatively, from native forest, plantations of bracatinga (Mimosa scabrella), eucalipt (Eucalyptus viminalis) and pinus (Pinus taeda) and frorn a bare soil. Ali, except lhe first soil, had been mined forthe extraction of "mineral pitch", before restoration. The work took place in an area belonging to PETROBRÁS, in São Mateus do Sul, Paraná State. The airn was to compare the effect of different types of plantation on the restoration of the soil disturbed by mining. The fungi population was used as parameter to measure the biodiversity in those soils. The bracatinga was the more efficient specie in getting the biodiversity close to the levels of soil from native forest.lt reached 83.3% ofthe original biodiversity. The modification in the levels of soil fertility that occurred in the soil under bracalinga changed the original microbiological balance that had a predominance of Paecilomyces, Chaetomium and Gongronella, towards a newbalancewith predominance of Trichoderma, Fusarium and Mucor this may indicate a successional process paralel to the undestorey vegetation in the plantation.
