Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | A rare species, confined to a few sites in southern England. Formerly, it occurred from Dorset (vc9) eastwards as far as South Essex (vc18). Recent records come from Filsham (vc14, East Sussex), Bewl Water (vc14 and vc16, West Kent) and Ashleworth Ham in West Gloucestershire (vc34). Associated with the drawdown zone of shaded waterbody margins. May be under-recorded. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Apparent association with a specific habitat feature - shaded drawdown zones - gives a target for specific management action. |
| 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: | Yes |
| Justification: | Conservation of areas of shaded drawdown when managing waterbodies may benefit this species. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 6. Recovery solutions trialled |
| Recovery potential/expectation: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: |
Key Actions
Key Action 1
Proposed Action: Provide stretches of shaded fluctuating waterbody margins with saturated litter under broadleaved trees wherever these occur. Ensure any management around waterbodies that may be suitable do not completely clear shading trees if not necessary for other conservation priorities.
Action targets: 6. Recovery solutions trialled
Action type: Habitat management
Duration: >10 years
Scale of Implementation: ≤ 50 sites
High priority sites: Filsham (vc14, East Sussex), Bewl Water (vc14 and vc16, West Kent) and Ashleworth Ham in West Gloucestershire (vc34).
Comments: Action will be ongoing but will be achieved best by reduced intervention in key areas.
