During our visit to Porto (Portugal), we discussed with Juan Vilela and Aitor Albaina from CEA (Centro de Estudios Ambientales, Vitoria-Gasteiz, Spain) and Txema Becerril from the University of the Basque Country our intention to submit new European proposals on the importance of preserving the unique biodiversity present in many metal contaminated sites, as well as on the importance of fostering biodiversity in phytoremediation and phytomanagement initiatives. Some of these proposals will focus on the links between biodiversity and the provision of ecosystem services.
