Importance and distribution in Luxembourg

Myriophyllum aquaticum is an invasive submerged/emergent aquatic weed characteristic of sub-tropical to warm-temperate regions, but found as far north as the UK. The species thrives in well-lit ponds, ditches, canals and slow-running streams. It is most often found in eutrophic water bodies and is able to grow as a terrestrial plant when ponds dry out, making it well adapted to medium water level fluctuations (Source: http://ias.biodiversity.be/species/show/76).

For Luxembourg, a single occurrence is documented. In June 2000, the plant was found in a pond (dead stream branch of the Alzette river) in Freschewisen, municipality of Roeser (Colling & Krippel 2003).
