Azolla as an invasive species

Azolla has been designated as an invasive species in some regions or countries.

It is essential to not introduce any species or subspecies of Azolla into regions or countries where it has been designated as an invasive species.

Details of countries where Azolla species and subspecies have been designated as an invasive species are given in the Invasive Species Compendium (ISC).  Although every effort is made to provide a comprehensive and up-to-date listing, the ISC and the Azolla Foundation do not take responsibility for the information given on their websites, because legislation is constantly being updated in different countries regarding the designation of individual Azolla species as being invasive.

The ISC lists three Azolla species in its compendium of invasive species. Details of these species are given on these pages of the ISC website: A. filiculoides, A. mexicana and A. pinnata, and they are also summarized on these pages of the Azolla Foundation website for A. filiculoides, A. mexicana and A. pinnata.

Data for individual species

A list of data provided by ISC for individual species is given on this page of its website.

These include the following:

Basic Datasheets: Basic datasheets are available for species that are invasive (but not yet populated with full data) or are associated with invasive species, threatened species, country datasheets, pathway datasheets and habitats. Data have been downloaded from CAB Abstracts and other reference databases by a process of ‘data mining’ and automatic cross-checking. This data may provide useful indications of the identity, distribution and relationships of these entries, but it must be noted that not all the data in this form have been manually checked by CABI editorial team.

Distribution Maps 
For detailed datasheets, geographic distributions have been researched by individual contributors and when available.

Definitions used in the Invasive Species Compendium

The following working definitions have been applied during the development of this compendium.

Invasive (alien) species: an (alien) species whose establishment and spread threaten ecosystems, habitats or species with economic or environmental harm. 

Introduced species (alien, non-native): A species, subspecies or lower taxon, introduced outside its natural past or present distribution; includes any part, gametes, seeds, eggs, or propagules of such species that might survive and subsequently reproduce.

Native species: A species, subspecies, or lower taxon, occurring within its natural range (past or present) and dispersal potential (i.e. within the range it occupies naturally or could occupy without direct or indirect introduction or care by humans.)
