Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: NT, criteria: B2ab(ii,iv): no evidence of recent decline. Confined to the S coasts of England and Wales.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Absent from many apparently suitable sites
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 - Relict or natural rarity
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Entirely restricted to S coast, in a variety of hot, dry, south-facing habitats including shingle, stable sand dunes and sparse cliff-top maritime grassland

Key Actions

Key Action 1

Proposed Action: Targeted survey of all known sites and similar intervening habitat

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 2 years

Scale of Implementation: ≤ 20 sites

High priority sites: south coast from N Kent to Cornwall

Comments:

Key Action 2

Proposed Action: Autecological research to establish microhabitat requirements at apparently contrasting sites

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Sandwich Bay, Kent (dunes); Chesil/Portland, Dorset (shingle); Outer Froward Point, Devo (cliff-top).

Comments: Target reliable and contrasting sites

Key Action 3

Proposed Action: Manage scrub and graze/mow aftermath where needed to maintain open grassland

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 20 sites

High priority sites:

Comments: Liaise with site managers to ensure integration into management plans
