Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Vulnerable in GB and rare in England. Appears to have declined in recent decades. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Evidence gaps limit understanding. A rare specialist of mesic bark on veteran trees in open conditions. Current status uncertain. |
| 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: | Maintaining and improving habitat quality is likely to be the most effective conservation measure. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Extinction debt |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | A small internationally rare specialist of mesic bark on veteran trees in open conditions, typically found in parklands. With an eastern sub-oceanic distribution. The species requires skill to find but there are very few recent records and it is definitely very rare. It's vulnerable to ammonia pollution. |
