| Section 41 Status: | (not listed) |
| Taxa Included Synonym: | (none) |
| UKSI Recommended Name: | Hieracium crebridens |

Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Hieracium crebridens is a scarce English endemic in the Yorkshire Dales and north-east England, known historically from 16 locations but only five post 2000 sites in Yorkshire and now described as rare (Jones 2014) and little is known about it - 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. 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: | Yes |
| Justification: | would benefit reduction in grazing at landscape scale in Yorkshire Dales. |
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: Survey of all sites to asses possible reasons for decline, and collect autecological data (vegetation niche, management) to assess conservation requirements.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 20 sites
High priority sites:
Comments: Medium priority for continued action amongst hawkweeds
Key Action 2
Proposed Action: Collect seed for Millennium Seed Bank
Action targets: 5. Remedial action identified
Action type: Ex situ conservation
Duration: 1 year
Scale of Implementation: ≤ 5 sites
High priority sites:
Comments: Coordinate with Millennium Seed Bank
Key Action 3
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
