Criteria
Question 1: | Does species need conservation or recovery in England? |
Response: | Yes |
Justification: | CR, criteria: B2ab(ii,iii,iv): status unchanged, with no records since 1985. Only recorded from 3 hectads in S England. |
Question 2: | Does recovery/ conservation depend on species-specific actions? |
Response: | Yes |
Justification: | Not recorded since 1985 despite 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 - sufficient |
Species Comments: | Found among stones on a (now destroyed) quarry floor in Somerset and in damp grassland (IoW). On the continent it occurs in a wide range of habitats including tussocky grassland. |
