État de la populationTexte officiel évaluation IUCNExpert

E. gracile is classed as Regionally Extinct in Croatia, Endangered in Norway, Denmark and Switzerland, Vulnerable in Estonia and Near Threatened in the UK.

It is clear that many populations are in decline, many significantly so and that this decline is partly due to the degradation of its habitat that is occurring to wetlands throughout the region. Recent intensive survey work in Ireland (Conaghan and Sheehy Skeffington 2009) has shown that this species is more abundant than would have been evident from casual records, but it also supported the conclusion that populations continue to be lost. In Sweden it is classed as Least Concern. Recent wetland inventories and flora projects have revealed that this species is rather common in the northern third of Sweden, and not declining. Further south it is rarer, and has declined in many areas.

Description complète des menacesTexte détaillé évaluation IUCNExpert

E. gracile appears to be susceptible to drainage and eutrophication, the former leading to loss of suitable habitat and the latter to aggressive succession which excludes this species.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

E. gracile is classed as Regionally Extinct in Croatia, Endangered in Norway, Denmark and Switzerland, Vulnerable in Estonia and Near Threatened in the UK.

There are populations on protected sites throughout much of its range, however it appears that few active measures have been taken toward conservation of this species.
