Soil trace metal content does not affect the distribution of the hyperaccumulator Noccaea caerulescens in the Vosges Mountains (France)

Aims Noccaea caerulescens is a pseudo-metallophyte known to hyperaccumulate Zn, Cd and Ni, and a model species for the study of the hyperaccumulation of trace metals. However, information about its ecology is rather scarce. The aim of this work was thus to determine if soil metal content was the main factor responsible for the distribution of N. caerulescens.
