Abstract

Superficial water quality was monitored in plantation areas with exotic species (Pinus taeda e Pinus ellioti) in Joinville coutry, Santa Catarina, Brazil, between September 2005 and July 2006. The results, obtained in the monitoring area through the comparison of different forested catchments of different forestry ages, were compared with the ones of the native forest. The parameters used in monitoring were temperature, pH, dissolved oxygen (DO), oxygen biochemist demand (OBD), total solids dissolved (TSD), turbidity, and thermo tolerant coliforms (TC). The most significant result was: an average increase of 0,4 units of pH, 42 NMP/100 mL of TC, comparing the water quality in the entrance and exit of the forestry. It had greater stability at temporal and spatial variation in pH values in the oldest forestry. Preliminary, this research showed that the silviculture does not considerably intervene in the superficial water quality.
