Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | (No GB Red List for micro-moths.) Highly restricted distribution. Main hostplant susceptible to loss through competition or mis-management. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Targeted action to preserve and increase populations of Water Dock is required. |
| 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: | See Q2 |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 1. Taxonomy established |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Difficult to access potential breeding sites to carry out surveys. |
Key Actions
Key Action 1
Proposed Action: Determine whether one of the two Suffolk colonies has been exterminated by work to prepare for a Fen Raft Spider introduction.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 1 year
Scale of Implementation: 1 site
High priority sites: Carlton Marshes
Comments: This incident demonstrates the importance of far more detailed investigations before species introductions take place.
Key Action 2
Proposed Action: Bespoke surveys for larvae at potential and former sites in the Norfolk Broads and on coastal shingle sites in south-east England and East Anglia in order to ascertain threat level.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 3-5 years
Scale of Implementation: ≤ 50 sites
High priority sites: Norfolk Broads
Comments: To ensure that presence is known at all occupied sites in order to reduce the risk of incidents like that at Carlton Marshes from taking place.
