Hydrological requirements of Vertigo moulinsiana (ENRR549)

The report describes the combined results of two projects that were commissioned to make quantitative determinations of the hydrological requirements of the land-snail Vertigo moulinsiana (Dupuy, 1849) on 3 English SACs. The project was undertaken within small study areas at Chilton Foliat (Wiltshire), Market Weston Fen (Suffolk) and Thompson Common (Norfolk), which lie within the Kennet and Lambourn Floodplain, Waveney and Little Ouse Valley Fens and Norfolk Valley Fens SACs respectively.
