Qualifying criterion: 4.6: very rare (less than 5 sites); associated with fens and upland flushes; threatened in 3 out of 9 European countries with official Red Lists
Justification: the three known sites are all vulnerable to inappropriate management that does not take into account the fragile nature of the microhabitat
Threats: changes to groundwater conditions, eutrophiciation, peat extraction, creation of open water areas, trampling of moorland flushes
Action Required: Site protection and monitoring against habitat loss and degradation
