Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | There is very little information on this poorly known British endemic which is now classed as Data Deficient (Rich 2025 in press). It has been recorded historically in 20-25 locations from Wales to Derbyshire, with only 2 post-2000 records. Basic data required. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Targeted survey required to determine current status and requirements for conservation. Welsh seed held in Millennium Seed Bank. |
| 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: | would benefit reduction in grazing at landscape scale |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Medium-high |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | few specialist hawkweed surveyors |
Key Actions
Key Action 1
Proposed Action: Resurvey of all sites to asses possible reasons for decline, and collect autecological data (vegetation niche, management) to assess conservation requirements.
