Invasive aquatic plants in Europe
Introduction
This key is an identification tool for invasive aquatic plants and the close allies (‘look-alikes’). Part of the species is traded as ornamental plants for ponds and aquaria. As such they may escape cultivation and start colonizing natural environments and become a pest.
A total of 78 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. Distinguishing characters have been added for certain groups of closely related species. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. The key is regularly updated with new species and new photographs. This key is also available in French and Dutch.
EPPO-Q-bank
EPPO-Q-bank – Comprehensive databases on plant pests and diseases covers the following organism groups that contain quarantine organisms:
- Fungi
- Bacteria
- Invasive Plants
- Nematodes
- Arthropods
- Phytoplasma’s
- Viruses and viroids
The databases are managed by EPPO – the European and Mediterranean Plant Protection Organization and curated by internationally known specialists and contain specimen-based information including molecular data. The website offers the possibility to blast, in single- or multi-locus mode, sequences for identification.
