ABSTRACT
This work studied the composition and vegetation structure in three areas with different abandonmentcondition and two forest fragments in the Soratama quarry. The main purpose was to identify thevegetation community after ten years of abandonment mining activities, and to study propagule sourcesfor the experimental design of sewage sludge as an organic soil amendment. Data collection was doneusing quadrants. Study of composition and floristic structure made evident a mosaic of areas in differentsuccessional conditions because of the disturbance caused by mining, which are being noteworthyinfluenced by degrading agents like rainfall and wind, and present an extreme increase of exotic species.Mosaic is composed by areas with low species richness, low vegetation cover, and a high percentage ofbare soil and forest fragments with native floristic elements.
