Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | No modern collections at historical sites, apparently extinct in England |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Monitoring and surveys in previously occupied sites needed to establish presence or extinction in England |
| 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): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Only recent UK records are North Wales but was previous known from southern England |
Key Actions
Key Action 1
Proposed Action: Include this species as a particular target in surveys of suitable sites
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: Studland, Brighton, Worthing
Comments: Establishing the distribution is essential, but nothing is known of habitat requirements except at the North Wales site
Key Action 2
Proposed Action: If found during surveys use records to help determine habitat requirements and whether any existing monitoring programmes could include it.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: Unknown
High priority sites: where found
