Special Area of Conservation (SAC) Monitoring: Vertigo moulinsiana in Cors Geirch, Corsydd Llyn/Lleyn Fens cSAC (2004)
Desmoulin's whorl snail, Vertigo moulinsiana, is listed in the British Red Data Book as an RDB3 (Rare) species, is scheduled on Annex II of the European Habitats and Species Directive and is included on the UK Biodiversity Action Plan short-list of priority species. The purpose of this study was to undertake monitoring of the Vertigo moulinsiana population at Cors Geirch in order to determine the thresholds necessary to carry out a condition assessment, which is a requirement of the EU Habitats and Species Directive. The only data held aside from the associated report is photographic images that are also held within the report itself.

The monitoring of favourable condition followed the Common Standards approach outlined by the Joint Nature Conservation Committee, as adapted for the LIFE in UK River's project. Condition of the snail population and its habitat was carried out by measuring environmental variables and snail numbers at 5m intervals along two linear transects (150m and 40m in length). The results were logged onto Standard Recording Forms as developed for the LIFE Protocol. The attributes used to assess Condition were: - Area of occupancy of Vertigo moulinsiana in both transects - Population density of Vertigo moulinsiana in both transects - Vegetation species class - Ground moisture levels
