Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: GB Red List (Fox et al. 2019): LC; no long-term trend data available. Has suffered serious historical and recent losses of distribution in England in particular (remains widespread in western Scotland).
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: In woodland habitats requires rotational management; on bogs/heaths requires retention of small birches and Bog Myrtle, which are often removed during routine management.
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: Would benefit from management that creates early successional habitat in woodlands; also management that creates greater structural diversity of vegetation on bogs and heaths.

Species Assessment

Current step on the Species Recovery Curve (SRC): 7. Best approach adopted at appropriate scales
Recovery potential/expectation: Medium-high
National Monitoring Resource: Combination - insufficient
Species Comments: Some bespoke monitoring underway but not yet at sufficient sites to generate a population trend.

Key Actions

Key Action 1

Proposed Action: Ensure known sites are managed appropriately to provide a good supply of small birches and/or Bog Myrtle at all times. Requires bespoke advice to landowners which may sometimes conflict with routine site conservation management.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 20 sites

High priority sites: Whixall & Bettisfield Mosses, Shapwick Heath, Staffordshire/Nottinghamshire woodlands, Cumbrian mosses

Comments:

Key Action 2

Proposed Action: Undertake adult and/or larval surveys at all remaining sites at least once every 3-5 years.

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 3-5 years

Scale of Implementation: National

High priority sites: Whixall & Bettisfield Mosses, Shapwick Heath, Staffordshire/Nottinghamshire woodlands, Cumbrian mosses

Comments:

Key Action 3

Proposed Action: Bespoke monitoring currently underway at just 2 sites. Establish annual monitoring at an additional 5-10 sites in order to be able to generate a population trend for this species. Monitoring can be undertaken at either the adult or larval stage.

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Targeted monitoring

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: Whixall & Bettisfield Mosses, Shapwick Heath, Staffordshire/Nottinghamshire woodlands, Cumbrian mosses
