Hyperaccumulation of nickel to concentrations above 1000 mg/kg on a dry matter basis has become recognized as an unusual response by some plant species to the elevated nickel concentrations generally found in soils derived from ultramafic rocks (often referred to as serpentine soils). Such soils are widespread in the Balkans. The objectives of the study were to widen understanding of the distribution of the nickel hyperaccumulators and their uptake behaviour in relation to the characteristics of their native soil environments. Collection and chemical analysis of both plant and soil samples has allowed evaluation of phenotypic efficacy in hyper accumulating nickel. In total, eight taxa were studied.
