Importance and distribution in Luxembourg
Pale bridewort is a shrub that prefers moist to wet conditions and grows on soil with abundant nutrients and organic material. It occurs mainly in riparian habitats such as on river banks, in wet meadows, swamps, ditches and bogs. This pioneer species needs full sunlight for optimal growth, flowering and fruiting but may survive under the tree canopy. It reproduces mainly vegetatively and may be propagated via garden waste or waterflow. It forms stable and very dense shrub communities that can expand over large areas and displace native plant species. The dense cover of this plant prevents tree regeneration and inhibits the successional process towards a forest stage (Source: http://ias.biodiversity.be/species/show/141).
The first documented occurrence of the species in Luxembourg dates from 1949. It was found on 5th August 1949 in Ousterbësch, municipality of Larochette (Beck et al. 1952). Only two observations are indicated in the Recorder database.
ISEIA protocol: C1 (1+1+3+2) (Ries et al. 2013: 19).
