Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: EN, criteria: B2ab(ii,iii): no change since review. Only recorded in GB from 3 hectads in E Kent - and only 1 of them this century
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Extremely restricted range even in relation to specialist habitat
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: Recorded from fixed and yellow sand dunes on the E Kent coast. A likely natural rarity and edge of range species.

Key Actions

Key Action 1

Proposed Action: Targeted survey of adjacent and other similar dune systems in Kent, using standardised methodology to confirm 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: ≤ 5 sites

High priority sites:

Comments: Target to coincide with what appears to be a primarily autumn maturation season. Likely to require pitfall-trapping/grubbing cf vacuum sampling.

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: 1 site

High priority sites: Greatstone-on-Sea, Kent

Comments:

Key Action 3

Proposed Action: Ensure site managers are aware of species past/recent presence and vulnerability on their sites on their sites. Update them with Action 1 and 2 results to provide any resulting guidance on locations/management and inform commissioning of invertebrate survey work (methods likely to detect/damage species, need for retention and examination of spider by-catch when not a survey target)

Action targets: 5. Remedial action identified

Action type: Advice & support

Duration: Unknown

Scale of Implementation: ≤ 5 sites

High priority sites: Greatstone-on-Sea and Sandwich Bay, Kent

Comments: Assemble mailing list and update site managers at species-appropriate intervals; most easily delivered by BAS/SRS.
