Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Only seems to be known from 1 extant site in Northumberland (2016). |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Only seems to be known from 1 extant site in Northumberland (2016) so targeted action is likely necessary. |
| 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): | 3. National Monitoring Plan agreed and implemented |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Latest record seems to be 2016 from Northumberland, possibly just the one extant site, although may have been recorded since. Older records from other N Pennines sites. |
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: ≤ 10 sites
High priority sites: All previously known sites, plus sample of other potential sites
Comments: Not clear if older sites have been revisited. Most recent site also needs a visit to assess current status, threats etc.
Key Action 2
Proposed Action: Survey sites with no recent information (identified through A1) to update status assessments, identify habitat management issues and identify actions required to address them
Action targets: 5. Remedial action identified
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 5 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 A2
Action targets: 7. Best approach adopted at appropriate scales
Action type: Advice & support
Duration: 6-10 years
Scale of Implementation: ≤ 5 sites
High priority sites:
Comments: Positive impacts on many threatened lichen species. Potential to bundle this with other grazing dependant woodland species.
