An assessment of the condition of the Narrow-mouthed Whorl Snail Vertigo angustior at Whiteford Burrows NNR, October 2018
Single day assessment visit was undertaken in October 2018. which allowed an overview site-survey, combined with off-site bulk sample analysis, to assess most of the sand dune/salt marsh transition zone and allowing the field assessment of the snail at 11 sites, which also involved the removal of bulk vegetation samples for off-site determination of snail presence. The results revealed V. angustior to be present at seven sites including several in the northern transition zone, an area in which the snail had not been recorded previously and which had been overlooked for study since the 1993 survey. The 2018 results demonstrated the presence of the snail over a linear distance of 1.9km extending the previously recorded range by 1.2 km, a 171% increase
