First report of Cabomba caroliniana in France
In France, Cabomba caroliniana (Cabombaceae, EPPO List of IAP) has been recorded for the first time on the Bourgogne canal in Dijon during the hottest period of summer 2005. A study had been undertaken since 15 km of the canal had been significantly invaded over this period. This study ascertained that in general, indigenous species were present, but noted the new occurrence of C. caroliniana. Water analysis did not show any quality degradation in the canal. Until now, C. caroliniana is only considered casual in France.
