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).
