The study has three main objectives: validating regional soil quality monitoring standards against soil productivity potential; determining the productive potential of the land for vegetative growth; and understanding how soil porosity and site organic matter interact to regulate long-term site productivity. The biotope features is determining the vegetation type.
Usually the soils have a natural charge of heavy metals originating from the native bedrock chemical composition. The heavy metals are determining the presence or the absence of some certain species in the vegetation habitat influencing biodiversity, some of the species being indicators for some metals growing and spreading better in the presence of the increased concentration of them. The purpose of this work is to show the interrelation between the concentrations of heavy metals in soil and the vegetation habitat biodiversity.
Soil and vegetation samples were taken according to the authorized general procedures. From the mineralized samples, heavy metals concentration was determined by atomic absorption spectrometry. The results obtained were compared to the reference soil and vegetation samples taken from a mountain area considered unpolluted. Some metals are determining a powerful decrease of the vegetation biodiversity the greatest impact being determined in the case of copper, nickel and zinc.
