Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | VU, criteria: D2. still only a limited area of a single site in S England. Threat status likely to increase at next review. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Very much rarer than its SE of England chalk pit location would suggest |
| 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: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Apparently a thermophilic species, found in sparse, calcareous broken ground/short grassland at a single Kent quarry site. |
Key Actions
Key Action 1
Proposed Action: Targeted survey of entire, extensive known site, and of other Kent quarries/sparse chalk grassland sites, to improve status assessment
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 5 sites
High priority sites: Culand Pits, Burnham and other N Kent chalk pits
Comments:
Key Action 2
Proposed Action: Consider the potential for site designation to protect this species and the important thermophilus calcareous grassland assemblage with which it is associated.
Action targets: 7. Best approach adopted at appropriate scales
Action type: Site protection
Duration: 3-5 years
Scale of Implementation: 1 site
High priority sites: Culand Pits, Burnham, Kent
Comments: Site is a Wildlife Trust reserve with only RIGS designation
Key Action 3
Proposed Action: Site management to control scrub invasion of open chalk and visitor pressure
Action targets: 7. Best approach adopted at appropriate scales
Action type: Habitat management
Duration: >10 years
Scale of Implementation: 1 site
High priority sites: Culand Pits, Kent
Comments: Invasion particularly of non-native Cotoneaster species threatens open bare and sparsely vegetated chalk. Frequent fire pits left by visitors in more open areas.
