A survey of the Broadland distribution of the swollen spire snail (Pseudamnicola confusa) (Frauenfeld) (ENRR319)

This survey examined the distribution of Pseudamnicola confusa in Broadland. It aimed to gain data on densities, habitat vegetation, mud structure, chloride levels, and other possible factors affecting the ecology of the species. The survey included an assessment on the decline of Glyceria maxima and the management strategies to conserve the habitat for the mollusc. The Yare valley was the subject of extensive plans for bank reinforcement and development employing different rond profiles. In identifying existing sites the survey aimed to advise on suitable bank profiles necessary to conserve the mollusc.
