Sticta canariensis
Key Details
| Taxonomic Groups: | Fungus or lichen > lichen > Lichen |
| Red List Status: | Vulnerable (Not Relevant) [VU(nr)] |
| D5 Status: | Included in the baseline Red List Index for England (Wilkins, Wilson & Brown, 2022) |
| Section 41 Status: | (not listed) |
| Taxa Included Synonym: | (none) |
| UKSI Recommended Name: | Sticta canariensis |
| UKSI Recommended Authority: | (Bory) Bory ex Delise |
| UKSI Recommended Qualifier: | (none specified) |
| Red List Citation: | Woods & Coppins, 2012 |
| Notes on taxonomy/listing: | sensu stricto (green morph) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | There do not appear to be any records of the independent green (algal) morph in England, but this needs clarification. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Status in England needs clarification before it can be determined whether further species-specific action is warranted. |
| 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: | At this stage, this seems unlikely. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 3. National Monitoring Plan agreed and implemented |
| Recovery potential/expectation: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Records appear confused between the cyanobacterial morph, green algal morph (which this entry relates to) and the combined morph i.e. with the cyanobacterial or combined morph recorded as canarensis, implying s. str. There do not appear to be any recent records of the independent green morph from England. |
Key Actions
Key Action 1
Proposed Action: Review records, both herbaria and in the field where necessary, to establish status in England (collecting data on all three morphs). Consider using DNA analysis.
Action targets: 3. National Monitoring Plan agreed and implemented
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 50 sites
High priority sites:

There do not appear to be any recent records of the independent green morph from England.
Key Action 2
Proposed Action: If the outcome of A1 is positive, produce a species dossier to collate information on current and historic sites, including results of surveys and assessment of threats and remedial actions.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 1 year
Scale of Implementation: ≤ 50 sites

Comments:
Key Action 3
Proposed Action: If the outcome of A1 is positive, advise and support site owners and managers to implement the site-level actions identified in A2.
Action targets: 7. Best approach adopted at appropriate scales
Action type: Advice & support
Duration: 6-10 years
Scale of Implementation: ≤ 50 sites
