Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | VU, criteria: D2: Last recorded 1994-2000 in 1 of 3 known calcareous grassland sites in SE England. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Much more restricted than its chalk grassland 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 - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Appears to be a thermophilic species of short, south-facing chalk swards, most likely at edge of range. Location of two of the sites are not known beyond 'Surrey' and 'Sussex' |
Key Actions
Key Action 1
Proposed Action: Targeted resurvey of Castle Hill, Folkstone and other steep, south-facing chalk grasslands on the Folkestone escarpment and South Downs
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: Unknown
High priority sites: Castle Hill, Folkstone and other steep, south-facing chalk grasslands on the Folkestone escarpment and South Downs
Comments:
Key Action 2
Proposed Action: Awareness raising primarily for invertebrate specialists working on chalk grasslands in SE England: may contribute new distributional information and/or preservation for ID by experts of spider by-catches from work on other taxa in suitable habitat.
Action targets: 2. Biological status assessment exists
Action type: Education/awareness raising
Duration: 3-5 years
Scale of Implementation: Not applicable
High priority sites: Sussex, Surrey and Kent chalk grasslands
Comments: Deliver by BAS and NE regional and national contacts with species specialists/specialist groups
