No results: no species in Luxembourg meet the strict “Endangered” criteria
The label “Endangered Species in Luxembourg” returns no exact matches. Luxembourg’s lists and international lists use strict definitions and thresholds. No species in the country currently meet that exact national/IUCN “Endangered” classification as defined for this post.
Explain why this happens. Use strict terms like “Endangered” only when a species meets specific criteria set by the IUCN or by a national red list. Luxembourg is small and has few species that are assessed at that national level. Many species are instead listed as “Vulnerable”, “Near Threatened”, “Protected”, or “Data Deficient.” Some species are assessed only at a larger European level, not by a separate Luxembourg category. In short, the exact tag “Endangered” can be rare or absent for a given country.
Consider technical and historical reasons. Countries follow different rules and update lists at different times. Some species decline across Europe but are stable locally. Some highly threatened species occur only as migrants or occasional visitors, so they do not reach the national “Endangered” threshold. Data gaps and recent recoveries or local extinctions also change statuses. Near matches include IUCN-listed species found in Luxembourg (for example, the European eel, Anguilla anguilla), species listed as “Vulnerable” or “Near Threatened” on national red lists, and species protected under EU Natura 2000 or the Habitats Directive.
Explore related categories instead. Check “Threatened species in Luxembourg”, “Protected species and Natura 2000 priority species”, national red lists by taxon (birds, bats, amphibians, plants), IUCN-listed species present in the country, and endangered habitats such as wetlands or old-growth forest patches. Use those lists, a sortable table, and mapped records to find species of conservation concern in Luxembourg.
