Importance and distribution in Luxembourg
The first documented occurrence of the species in Luxembourg dates from 1993. It was found on 9th August 1993 at Wintrange, Municipality of Schengen (Schmidt 1993). 11 observations located in the Moselle and Lower Sûre valleys and in the south-west of the country close to the French border are found in the Recorder database (08/01/2018).
The narrow-leaved Michaelmas-daisy thrives both in ruderal and riparian areas, especially on rich and moist to humid soils. Commonly planted in gardens, it then gets propagated through fly-tipping of green waste. Seed development depends on climatic conditions. Asters are rhizomatous species, and can propagate clonally. They easily form dense and wide monospecific colonies displacing native wetland plants, favouring sedimentation and stabilization of riverbanks which reduces the ability of rivers to meander and flood (Source: http://ias.biodiversity.be/species/show/137).
ISEIA protocol: C1 (2+2+2+1) (Ries et al. 2013: 18).
