Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Geographically restricted to oceanic areas, appears to be on the increase, but likely to be EN in England red list. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Evidence gaps. Research into distribution and autecology needed. |
| 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: | Yes |
| Justification: | Likely to benefit from expansion of well-lit woodland/woodland edge, wood pasture etc |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: |
Key Actions
Key Action 1
Proposed Action: Produce a species dossier to collate information on current and historic sites, including results of surveys and assessment of threats and remedial actions
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 1 year
Scale of Implementation: Not applicable
High priority sites:
Comments: Needs review of records to establish current status on sites, monitoring status, overlap with SSSIs, threats, remedial actions etc.
Key Action 2
Proposed Action: Resurvey all known sites, especially where the species has not been recently recorded and identify recovery actions/trial management.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 1 year
Scale of Implementation: ≤ 100 sites
High priority sites:
Comments:
Key Action 3
Proposed Action: Advise and support site owners and managers to implement the site-level actions identifies in A1 and A4
Action targets: 7. Best approach adopted at appropriate scales
Action type: Advice & support
Duration: 6-10 years
Scale of Implementation: ≤ 100 sites
High priority sites:
Comments: Positive impacts on many threatened lichen species. Potential to bundle this with other grazing dependant woodland species.
