NatureScot Commissioned Report 615: Whorl snails (Vertigo spp.) surveillance in Scotland: a condition assessment of the narrow-mouthed whorl snail Vertigo angustior in Aberdeenshire
The narrow-mouthed whorl snail Vertigo angustior is listed on Annex II of the EC Habitats Directive. In Scotland the species is known only from two coastal locations at White Port on the Solway and in two places at Perthumnie Bay in Aberdeenshire. To provide information for the next round of Article 17 reporting, a condition assessment of V. angustior has been carried out by using methods designed to allow assessments of population, habitat and prospects. Although small in area, the habitat at both Garron Point and Red Man Bay is in good condition for Vertigo angustior, and the snail is present at several places within each site and in moderately high abundance. The assessments for population, habitat and future prospects are all 'favourable - maintained', and therefore, the overall assessment is 'favourable - maintained'.
