First record of Salvinia molesta in Corse (FR)
Salvinia molesta (Salviniaceae, EPPO Alert List) was observed for the first time in 2010 in Corse (FR), in a 900 m² water reservoir, south of the Ajaccio Gulf. S. molesta was covering the entire reservoir over a depth of 75 cm. The plant was most probably introduced by human activities 20 years ago, but it has not spread to other waterbodies as the reservoir is very isolated.
