Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Very rare upland woodland rainforest specialist found on smooth bark, only known from one rainforest site in England. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Very rare upland woodland rainforest specialist. Status uncertain, targeted survey required. |
| 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: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Only two records for England - an old (pre-2000) record from Cumbria and a more recent (post-2000) record (collection - specimen?) from Devon which may be referable to another species. |
Key Actions
Key Action 1
Proposed Action: Follow up on old records inc. resurvey of Cumbria site and confirm ID of Devon specimen. If refound, collect data on threats, remedial measures and autecology.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 1 year
Scale of Implementation: ≤ 5 sites
High priority sites: 1 in Cumbria, 1 in Devon
Comments:
Key Action 2
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: 5. Remedial action identified
Action type: Scientific research
Duration: 1 year
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: Seatoller, Borrowdale
Comments: The habitat appears somewhat under grazed for Atlantic Hazel wood conservation, but there is pressure to reduce grazing further. The conflicting assessments require resolving.
