Abstract: The arrival of Water Hyacinth plants (Eichhornia crassipes (Mart) Solms.) at the beaches of the Galician Atlantic Islands Maritime-Terrestrial National Park is assessed as a consequence, of a long distance transport of individuals coming from naturalized populations located on the Portuguese coast. This South American native species is highly invasive due to its fast growing and high reproductive capacity. Water hyacinth is named by the IUCN as one of the top one hundred of the world’s worst invasive alien species. It was first cited in Europe during the first half of the 20th century, in central Portugal, from where it has expanded mostly throughout the catchments of Tejo and Sado Rivers, although there are some other known populations in the north of Portugal. Its presence is quite
exceptional in Galicia, being scarcely cited as it is normally linked to eradication events. During 2011 and 2012, after some SW squalls had passed by, some Eichhornia crassipes (Mart) Solms. remains were detected in one of the beaches of Cíes Island. Based upon the amount of plants, and the deterioration degree of the remains, it is thought that they have been transported from a big distant population.

Key words: Water Hyacinth, Galician Atlantic Islands Maritime-Terrestrial National Park, invasion, long-distance transport.
