Criteria
Question 1: | Does species need conservation or recovery in England? |
Response: | Yes |
Justification: | Clearly very rare in England with most records representing brackish coastal sites but also a few brackish inland sites plus a few anomalous non-Brackish sites. Very rare in Wales and Scotland. Near Threatened in Europe (IUCN). |
Question 2: | Does recovery/ conservation depend on species-specific actions? |
Response: | Yes |
Justification: | Currently there is insufficient understanding of the specific needs of this species . |
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): | 4. Autecology and pressures understood |
Recovery potential/expectation: | Unknown |
National Monitoring Resource: | Opportunistic - insufficient |
Species Comments: | Preserving, enhancing and improving the connectivity of brackish coastal marsh, especially the presence of Sea Clubrush and Common Reed, will be of importance. |
Key Actions
Key Action 1
Proposed Action: Specific targeted surveying/monitoring in its key area to investigate its current status (to feed into a revision of the Red List), the extent of populations and whether there are specific habitat needs. This could be linked to the Lejops vittata work.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 50 sites
High priority sites: Christchurch Harbour, the Solent, Sussex, Kent, Thames Gateway and East Anglia.
