Freshw<strong>at</strong>er molluscs Four percent* of freshw<strong>at</strong>er molluscs th<strong>at</strong> occur in Luxembourg are thre<strong>at</strong>ened <strong>at</strong> the European level and all of them are classified as Critically Endangered. Declining w<strong>at</strong>er quality in freshw<strong>at</strong>er rivers and lakes caused by agricultural, forestry and domestic effluents is the main thre<strong>at</strong> to this group <strong>at</strong> the European level. Habit<strong>at</strong> degrad<strong>at</strong>ion as a result of inappropri<strong>at</strong>e ecosystem management shipping lanes and the construction of dams are also major thre<strong>at</strong>s to this group. St<strong>at</strong>us <strong>at</strong> European level Vascular plants At European level, priority crop wild rel<strong>at</strong>ives, aqu<strong>at</strong>ic plants and all species included in the annexes of the Habit<strong>at</strong>s 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 conserv<strong>at</strong>ion st<strong>at</strong>us of vascular plants in Luxembourg based on the European Red List d<strong>at</strong>a is rel<strong>at</strong>ively good since less than 1%* of them are considered thre<strong>at</strong>ened and 92% is classified as Least Concern <strong>at</strong> the European level. For terrestrial plants, habit<strong>at</strong> degrad<strong>at</strong>ion due to urban development has the worse impacts. For aqu<strong>at</strong>ic species, n<strong>at</strong>ural system modific<strong>at</strong>ions are the main thre<strong>at</strong>.

Since the number of thre<strong>at</strong>ened species is often uncertain because it is not known whether DD species are actually thre<strong>at</strong>ened or not, this formula considers th<strong>at</strong> DD species are equally thre<strong>at</strong>ened as d<strong>at</strong>a sufficient species.
