| Qualifying criterion: 4.7: very rare with restricted range |
| Justification: this species has shown approximately 50% decline in pre- and post-1960 hectads, although recording frequency within sites has increased |
| Threats: felling of host trees, trampling, compaction, forestry operations, track maintenance, eutrophication, overgrowth |
| Action Required: Site protection and monitoring against habitat loss and degradation; taxonomic research |
