What Alterations can be seen in the Soil Seed Bank after Eucalyptus Harvest?
Abstract The objective of this study was to assess the potential and the alterations of the soil seed bank as a mechanism for the regeneration of tree species in disturbed forest fragments after Eucalyptus grandis harvest. Soil samples were collected in two periods, during the winter and summer, in areas with different ages after E. grandis harvest. In each environment, 20 samples of soil were collected, with 60 samples per period (winter and summer), this samples were distributed in trays and arranged in open air for germination analysis. A total of 2,002 individuals were identified, belonging to 36 species and 17 families. The highest densities occurred during the summer, which also showed higher similarity between the environments. More species and diversity in relation to the ages of regeneration was observed during this period. Therefore, this study represents a contribution for further experiments in the field of conservation and restoration.
