Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | A species only present in England. Although relatively locally distributed the snail is maintaining good populations at a number of sites in East Sussex e.g. Southerham Down, Lewes; banks of River Ouse south of Lewes, dunes near Rye Harbour so no actions are proposed at this time. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Appears to be doing well at its East Sussex sites and requires general management to maintain its open, unshaded (but not over-grazed) habitat |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | No |
| Justification: | This species would not benefit from untargeted management |
