Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Assessed as NT at a GB level in 2005 and LC at England-level in 2014 (Stroh et al., 2014). Plant Atlas 2020 reported a moderate long-term decline since the 1950s suggesting that its range has contracted irrespective of differences in recording intensity (Stroh et al., 2023) but this is probably not sufficient to warrant bespoke, tailored conservation actions in England. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | This is a naturally rare species in England, some range contraction, likely sensitive to climatic and atmospheric conditions. |
| 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: | N/A |
