Dear Josè, as far as i know there is not so much info on the invasive status of Casuarina equisetifolia in Europe. C. equisetifolia is planted as ornamental in many Med. countries. The MEPA Guidelines on managing non-native plant invaders and restoring native plant communities in terrestrial settings in the Maltese Islands promotes actions to control C. equisetifolia. You might also try to contact expert from Cyprus and Azores, but I do not know if published literature is already available on that. C. equisetifolia is cited also by Ramon Vallejo in his work(s) on Restoring Mediterranean Forests. Another useful info source is the EPPO site, in the EPPO reporting service and on ISSG on-line data-base. Hope it helps, best wishes, Giuseppe

Dear Giuseppe, thank you very much for all the information.

In the Canary Islands we have some introduced populations (even big, of more than 1 km2) or isolated plants of Casuarina equisetifolia in public gardens and parks, and also in nature, but this species (at least for the moment) is not invasive here.
