Description

Matteuccia struthiopteris was considered as Regionally Extinct (RE) in Luxembourg, until 2017, when the Ostrich Fern was (re)discovered by K.-G. Gessner near Dondelange. The presence of M. struthiopteris along a hedgerow is probably the result of a garden escape.

Map Lycopodium clavatum

Further information

Lycopodium clavatum is considered as ‘critically endangered’. In the last decades however, the species was no longer observed in its known locations, and it was considered as possibly extinct!

Fortunately Jean Werner and Thierry Mahévas, investigating the bryophytes in the valley of the Mandelbaach near Brouch/Mersch found a new site of this extremely rare species in spring 2013, more than 20 years after the last observation made in 1992 in the north of Luxembourg (Krippel & Colling 2014: 110).

More information about Lycopodium clavatum in Luxembourg was compiled by Krippel & Massard (2019).
