Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: EN, criteria: B2ab(ii): status likely to improve when next reviewed because of conspicuous increase in records, especially in the SW. Most records from England.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Absent from much apparently suitable habitat. Climate-induced westward range shift looks possible but losses from S and E sites not understood, so currently justifies action.
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): 2. Biological status assessment exists
Recovery potential/expectation: Low - Combination or other (detail in comments)
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Found on dry heathlands and calcareous grasslands, often near to the coast. Likely ant feeder. Recovery potential likely limited by specialist habitat availability and climate change.

Key Actions

Key Action 1

Proposed Action: Targeted re-survey of former and similar nearby sites, using standardised methodology to assess current status (and establish baseline for national monitoring programme)

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 2 years

Scale of Implementation: ≤ 50 sites

High priority sites:

Comments: Main focus on all former E and S sites to ascertain extent of loss. Significant H&S issues with survey for this species at some sites - best practise for cliff top working to be strictly observed.

Key Action 2

Proposed Action: Autecological research to better characterise habitat requirements and inform management

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Kynance Cove, Cornwall; Seaford Head, E Sussex; any E.Anglia or Surrey heath site where it is re-found

Comments: Focus on reliable and contrasting sites

Key Action 3

Proposed Action: Site management to include scrub control with aftermath grazing to maintain short, open turf.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 50 sites

High priority sites:

Comments: Action likely to be integral to wider management objectives for sites
