The data have been collected in the Hauts-de-France Region in a metal-polluted site (Mortagne-du-Nord) and a non-polluted site (Quarouble). In Mortagne-du-Nord, data came from an experimental set-up, and include: elemental concentrations in soil (two depths: 0-20 cm and 20-40 cm), elemental concentrations in plant shoots of the different species, plant functional traits, indicators of ecosystem functioning (plant biomass production, plant biomass productivity and litter decomposition), and species abundances. In the non-polluted site of Quarouble, only plant functional traits, indicators of ecosystem functioning, and species abundances were measured.
