Importance and distribution in Luxembourg

Distribution map of Impatiens glandulifera Royle in Luxembourg. Recorder-LUX & iNaturalist, 2019.08.21.

The first documented occurrence of the species in Luxembourg dates from 1966. It was found by Léopold Reichling on 4th August 1966 in Koetschette (Municipality of Rambrouch). There are 7.106 observations indicated in the Recorder database (18/01/2018)

Himalayan balsam is one of the most common and widespread invasive neophytes in Luxembourg. It builds huge colonies along riparian ecosystems, often together with colonies of Bohemian knotweed. Several major rivers of Luxembourg are being affected. A worst case example can be seen along the river Sure between Ettelbruck and Michelau.

Since the end of the first decade of the 21st century, Himalayan balsam is increasingly spreading throughout the countryside, leaving the riverbanks and colonising other habitats like roadsides and forests. An example can be seen in the Our valley between Stolzembourg and Dasbourg-Pont, where the Himalayan Balsam managed to “jump” across the main road, to “climb” up the steep slopes and to “enter” the oak forests. In the meanwhile Impatiens glandulifera occurs in many forests across the country.

In summer 2017 the Nature Park of the Our Valley launched a pilot project to free the small river Blees (20 km) from Impatiens glandulifera, in co-operation with the National Museum of Natural History.

Two other alien balsam occur in Luxembourg, the invasive small balsam (Impatiens parviflora DC.), which is widespread in forest ecosystems across Luxembourg, and Balfour’s touch-me-not (Impatiens balfourii), first observed in 2016 in the wild in Luxembourg.
