Check-List and Red List of the Pteridophytes of Luxembourg

The Red List of the pteridophytes of Luxembourg applies the revised IUCN Red List categories [IUCN (2001). – IUCN Red List Categories and Criteria: Version 3.1. IUCN Species Survival Commission. IUCN, Gland, Switzerland and Cambridge, UK. ii + 30 pp.] at a national level. It is integrated in the Red List of the vascular plants of Luxembourg – Pteridophyta and Spermatophyta (Colling, G., 2005. – Red List of Vascular Plants of Luxembourg. – Ferrantia. Trav. Scientif. Mus. Hist. Nat. Lux. 42: 77 pp.). The checklist of pteridophytes on which the Red List is based on contains 60 plant taxa. Out of these, 13.3% are considered to be Regionally Extinct (RE), 6.7% Critically Endangered (CR), 6.7% Endangered (EN), 6.7% Vulnerable (VU), 8.3% of Lower risk – least concern (LRlc) and 23.3% Extremely Rare (R). 35% of all pteridophyte taxa are considered of being not threatened (*).
