Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | CR in England |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Relies on being dispersed by humans |
| 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: | This species would not benefit from untargeted management |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 5. Remedial action identified |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Probably extinct as a native |
Key Actions
Key Action 1
Proposed Action: Advice and support for land managers at recent and historic locations to encourage and enable targeted management.
Action targets: 7. Best approach adopted at appropriate scales
Action type: Advice & support
Duration: 1 year
Scale of Implementation: National
High priority sites:
Comments: Annual
Key Action 2
Proposed Action: Establish a programme of translocations at suitable sites across its natural range.
Action targets: 6. Recovery solutions trialled
Action type: (Re-)introduction
Duration: 3-5 years
Scale of Implementation: ≤ 50 sites
High priority sites:
Comments: Will require sourcing of suitable material for translocation, probably necessitating ex-situ propagation to bulk up seed. Ongoing monitoring of translocation sites needed after the duration of the action.
