Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Recent work has shown that although this Yorkshire endemic was once known from c. 5 localities, B. Burrow was unable to refind in any sites 2022-2023 and it is now Critically Endangered (Rich 2025 in press) or even Extinct. Requires targeted search and collection of seeds from any remaining populations to enable recovery. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Rediscovery in the field is essential; no seed 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: | No |
| Justification: | Unknown at this stage |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | few specialist hawkweed surveyors |
Key Actions
Key Action 1
Proposed Action: Survey of all 5 known sites a priority to rediscover it, and collect autecological data (vegetation niche, management) and collect seed for the Millennium Seed Bank.
Action targets: 2. Biological status assessment exists

Scale of Implementation: ≤ 5 sites
High priority sites: Lock Scar and Comb Hill
Comments: high priority for action amongst hawkweeds
Key Action 2
Proposed Action: Promote awareness of the group amongst landowners, understanding of conservation requirements amongst conservation professionals and identification skills amongst field botanists e.g. via BSBI training resources and workshops
Action targets: 5. Remedial action identified
Action type: Advice & support
Duration: 3-5 years
Scale of Implementation: ≤ 100 sites
High priority sites:
Comments: generic action
