Dutch elm disease (grafiosis in Spanish) arrived relatively late to Spain. It was first detected in the 1980s, though it may well have reached the country a decade before, and has decimated 80-90% of common elms (Ulmus minor) in Iberia. One of the very few elm stands to have survived in Spain is in Rivas Vaciamadrid, near Madrid, as it is isolated from other trees. Efforts are being made here to conserve the trees here and ensure a genetic bank from which one day to replant elms across the country.
