Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Extinct in England |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Recovery may be possible via reintroduction |
| 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: | The species is extinct and so is unlikely to benefit from untargeted actions |

Key Actions
Key Action 1
Proposed Action: Assess feasibility and develop a plan for reintroduction to Warwickshire
Action targets: 6. Recovery solutions trialled
Action type: (Re-)introduction
Duration: 1 year
Scale of Implementation: 1 site
High priority sites:
Comments: Formerly known from a single sandstone quarry in Warwickshire. The original site is destroyed but reintroduction could potentially occur to a suitable site elsewhere within the region.
Key Action 2
Proposed Action: Develop ex situ cultivation for use in reintroduction trial
Action targets: 6. Recovery solutions trialled
Action type: Ex situ conservation
Duration: 3-5 years
Scale of Implementation: Not applicable
High priority sites:
Comments: Not presently in cryopreservation or in culture. Material would need to be collected from mainland Europe.
