Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Urgently requires a recovery project of this Critically Endangered (Rich 2025 in press) Yorkshire endemic, now with one very precarious, declining population on one roadside at Linton (Rich et al. 2018). Verge needs managing properly. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | There are insufficient data to assess trends at subspecies level and so it is assessed the same as the species as EN due to a dramatic decline in its extent of occurrence since the 1950s (Stroh et al., 2014). See line in data for Hypopitys monotropa. |
| 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: | Remaining population too small to benefit from wider initiatives |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 5. Remedial action identified |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | few specialist hawkweed surveyors |
