Introduction
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 [IUCN (2012). Guidelines for Application of IUCN Red List Criteria at Regional and National Levels: Version 4.0. Gland, Switzerland and Cambridge, UK: IUCN. iii + 41pp.]. An initial version was 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 42: 77 pp. [3.5 MB]).
The checklist of pteridophytes on which the Red List is based on contains 62 plant taxa. Out of these, 12.9 % are considered to be Regionally Extinct (RE), 6.5 % Critically Endangered (CR), 6.5 % Endangered (EN), 6.5 % Vulnerable (VU), 8.1 % of Lower risk – least concern (LRlc) and 25.8 % Extremely Rare (R). 33.9 % of all pteridophyte taxa are considered of being not threatened (*).
