Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Assessed as LC in England with no evidence of a decline and still relatively widespread and possibly increasing in some areas due to conservation/habitat restoration schemes (Stroh et al., 2014). This was corroborated by Plant Atlas 2020 which showed that its overall distribution is stable. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | This species appears o be increasing in range. |
| 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: | This species does appear to have spread in areas where hay meadow restoration has been undertaken at a landscape scale (e.g. Thames Tributaries). |
