Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Endangered. Modern records from just four locations: Monks Wood (Huntingdonshire), the New Forest (Hampshire), Wappenbury Wood (Warwickshire), and Ashtead Common (Surrey). Highly fragmented, old records from a further 12 hectads, suggesting a major decline in an already highly localised species. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Minimum intervention management will not provide conditions suitable for the development of successive generations of veteran trees, and well-planned tree planting remains the exception rather than the rule. |
| 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): | 4. Autecology and pressures understood |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Polyphagous but oak is preferred; larvae feed in relatively moist red-rotten wood in close contact with living tissue, such as the bases of dead branches surrounded by living callus development as the healthy tree produces fresh woody tissues around the wound. It is thermophilous and consequently the preferred habitats are oaks growing on south facing slopes or sunny woodland edges. Old stunted oaks with plenty of wounds and dead branches still attached to the living trees are especially attractive to the beetle. |
Key Actions
Key Action 1
Proposed Action: Research to characterise the ecology of the beetle, in terms of the size, condition, situation and management of host trees
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: Monks Wood (Huntingdonshire), the New Forest (Hampshire), Wappenbury Wood (Warwickshire), and Ashtead Common (Surrey).
Comments: Only the New Forest has a long-term history of records for this species.
Key Action 2
Proposed Action: At sites where the species occurs, plant suitable host trees or promote natural regeneration on sites where there has been insufficient recruitment of younger age classes.
Action targets: 7. Best approach adopted at appropriate scales
Action type: Habitat management
Duration: >10 years
Scale of Implementation: ≤ 5 sites
High priority sites: Prioritisation is subject to assessment of tree age structure at all sites where the species occurs
Comments: Research in Scotland suggests that this is a species of developing aspen stands
Key Action 3
Proposed Action: Create a UK DNA sequence, and primers to allow eDNA sampling.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 2 years
Scale of Implementation: 1 site
High priority sites: Watersmeet Woods (Devon), New Forest (Hampshire), Savernake Forest (Wiltshire)
Comments: To allow a focus on larval development sites through less invasive detection in saproxylic substrates.
