Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: GB Red List (Fox et al. 2019): NT; no long-term trend data available. Suffered severe historical declines and now reduced to around 15 populations in England. Not present elsewhere in GB.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Ecology poorly understood and requires research. Bespoke surveys also required to determine current status. There is some evidence that coppicing of Sweet Chestnut is beneficial but this also needs more research.
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: Not entirely clear but increasing the structural diversity of woodland, particularly overstood Sweet Chestnut coppice, may be beneficial.

Species Assessment

Current step on the Species Recovery Curve (SRC): 1. Taxonomy established
Recovery potential/expectation: Medium-high
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Poor knowledge of current status and ecology. Some evidence of a positive response to Sweet Chestnut coppicing but research needed before management recommendations can be made.

Key Actions

Key Action 1

Proposed Action: Bespoke survey required in order to determine current status across range.

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 3-5 years

Scale of Implementation: National

High priority sites:

Comments:

Key Action 2

Proposed Action: Undertake research into larval ecology. Previous attempts have failed to find the larvae in the wild. Related species feed on hanging dead leaves but larvae of this species could not be found in that situation. Knowledge of larval requirements is essential to understand habitat management required.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites:

Comments:

Key Action 3

Proposed Action: Undertake research into the effects of coppicing on populations.

Action targets: 6. Recovery solutions trialled

Action type: Scientific research

Duration: >10 years

Scale of Implementation: ≤ 5 sites

High priority sites:
