Importance and distribution in Luxembourg
The species was first documented in Luxembourg by Léopold Reichling on 8th August 1952 in Manzenbaach, Municipality of Larochette. Since then, almost 200 observations have been recorded, especially in the central area of Luxembourg, while the north of the country is populated much more sparsely.
C. canadensis is considered a weed and is associated mostly with perennial crops, fallows and field borders. It also occurs on roadsides and appears as an early successional species on recently disturbed land. The species has a high spreading capacity due to its ability to adapt to different environments combined with high reproductive potential and high seed mobility.
ISEIA protocol: C3 (3+2+2+1) (Ries et al. 2013: 18).
