Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | VU at England level; |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Needs action directed at sites where it grows |
| 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: | Restricted to specific sites |
Species Assessment

Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: National
High priority sites:
Comments: Will need water sampling and testing
Key Action 3
Proposed Action: Implement management plans at sites to address need to maintain hydro-geological conditions necessary and appropriate annual management
Action targets: 6. Recovery solutions trialled
Action type: Habitat management
Duration: Unknown
Scale of Implementation: ≤ 50 sites
