Freshwater molluscs Four percent* of freshwater molluscs that occur in Luxembourg are threatened at the European level and all of them are classified as Critically Endangered. Declining water quality in freshwater rivers and lakes caused by agricultural, forestry and domestic effluents is the main threat to this group at the European level. Habitat degradation as a result of inappropriate ecosystem management shipping lanes and the construction of dams are also major threats to this group. Status at European level Vascular plants At European level, priority crop wild relatives, aquatic plants and all species included in the annexes of the Habitats Directive, Bern Convention and CITES have been assessed. A total of 295 species are found in Luxembourg, which represent 16% of the total of species assessed in Europe. The conservation status of vascular plants in Luxembourg based on the European Red List data is relatively good since less than 1%* of them are considered threatened and 92% is classified as Least Concern at the European level. For terrestrial plants, habitat degradation due to urban development has the worse impacts. For aquatic species, natural system modifications are the main threat.

Since the number of threatened species is often uncertain because it is not known whether DD species are actually threatened or not, this formula considers that DD species are equally threatened as data sufficient species.
