Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Regionally Extinct. None of the records are well documented and last recorded in Surrey in 1877. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | This species has not been recorded even as a vagrant in over 180 years, and so may be unlikely to naturally recolonise Britain from the continent. |
| 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: | Low - Combination or other (detail in comments) |
| National Monitoring Resource: | Opportunistic - sufficient |
| Species Comments: | Nothing has been published about the ecology of this species apart from an association with fresh oak palings |
Key Actions
Key Action 1
Proposed Action: Complete desk study to determine whether a reintroduction is feasible under current Natural England codes and guidance for England
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 2 years
Scale of Implementation: Not applicable
High priority sites: Not applicable
Comments: This will probably need to be completed in tandem with Action 2
Key Action 2
Proposed Action: Autecological research to better characterise habitat requirements and inform management
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: Unknown
Comments: As Tilloidea unifasciata is extinct in England, ecological studies would have to be based on fieldwork in Europe.
Key Action 3
Proposed Action: Reintroduction if this is judged to be feasible based on the results of Actions 1 and 2.
Action targets: 6. Recovery solutions trialled
Action type: (Re-)introduction
Duration: >10 years
Scale of Implementation: 1 site
High priority sites: Unknown
