Recently, unattached viable stem fragments of the invasive macrophyte Cabomba caroliniana Gray were found at several locations in two canals in northern Belgium. A subsequent survey of the canal Zuid-Willemsvaart revealed one site with rooted plants and the presence of floating stem fragments along the entire length of the canal (25 km). These findings indicate that C. caroliniana is already well established in the Zuid-Willemsvaart and probably considerably more widespread than previous records from isolated lentic water bodies indicate. We have summarised the new records and discuss the potential spread and risks associated with further establishment and spread of C. caroliniana in Belgium.
Résumé
Récemment, des fragments de tiges viables libres du macrophyte envahissant Cabomba caroliniana Gray ont été trouvés à plusieurs endroits dans deux canaux du nord de la Belgique. Une étude subséquente du canal Zuid-Willemsvaart a révélé la présence de plantes à racines et de fragments de tiges flottantes sur toute la longueur du canal (25 km). Ces résultats indiquent que C. caroliniana est déjà bien établie dans le Zuid-Willemsvaart et probablement beaucoup plus répandue que les signalements précédents dans des masses d'eau lentiques isolées l'indiquent. Nous avons récapitulé les nouveaux signalements et discuté de la dissémination potentielle et des risques associés à l'établissement et à la dissémination de C. caroliniana en Belgique.
