Aldrovanda vesiculosa is listed as Endangered on the IUCN Red List. It is native to Europe, Asia, Africa, and Australia, but is considered extinct in much of its native range, primarily due to eutrophication. Despite being endangered in its native range, it was introduced in the U.S. and has been reported to be rapidly spreading in the waters of the Catskill Mountains of New York, USA, where it is being evaluated as a potentially problematic invasive species.
