Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Was known (2014) to be present on about 13 stretches of ivy-covered limestone wall in a small area of Glos. Vulnerable to ivy clearance and wall restoration. A possible risk from collection. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | The current status is unknown. An assessment of current presence and then a monitoring plan is required. This might come out of the prep work for the mollusc review |
| 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 |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 4. Autecology and pressures understood |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: |
Key Actions
Key Action 1
Proposed Action: Undertake an assessment of species presence at sites it has been recorded at previously and the state of the occupied walls to feed into a possible update of the red list .
Action targets: 5. Remedial action identified
Action type: Targeted monitoring
Duration: 3-5 years
Scale of Implementation: ≤ 20 sites
High priority sites: Cluster in one region of Gloucestershire.
Comments:
Key Action 2
Proposed Action: Provide advice to wall owners on sustainable wall management to retain snail. In person advice could be expanded to the landowners/farmers and the highways agency for other areas of adjacent or nearby walls.
Action targets: 5. Remedial action identified
Action type: Habitat management
Duration: >10 years
Scale of Implementation: ≤ 20 sites
High priority sites:
