The first campaign of surveys on the Island of Giannutri has been concluded. This involved the mapping of invasive alien plant species and the definition of methods of control and eradication. The species most widespread and dangerous to the conservation of the island’s biodiversity are all the ornamental plants, such as Caprobotus edulis (known as the Hottentot fig), Senecio angulatus and Mesembryanthemum cordifolium.
