Clubiona genevensis
Key Details
| Taxonomic Groups: | Invertebrate > spider (Araneae) > Spider |
| Red List Status: | Near Threatened (Not Relevant) [NT(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: | Porrhoclubiona genevensis |
| UKSI Recommended Authority: | (L. Koch, 1866) |

Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | NT, criteria: B2a. Last seen at Dorset sites in 1945 and now apparently restricted to the far west of Cornwall, plus Isles of Scilly, and Wales (4/10 recorded hectads). |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Absent from much apparently suitable habitat |
| 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): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Combination or other (detail in comments) |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Restricted to open, stony maritime grassland/scree where it is found under small stones on bedrock. A natural rarity because of restricted habitat, but may also be undergoing a climate change induced W range shift |
Key Actions
Key Action 1
Proposed Action: Targeted re-survey of recorded, nearby and other suitable sites, using standardised methodology to assess current status (and establish baseline for national monitoring programme)
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 10 sites
High priority sites: Lulworth Cove, Dorset; Lizard peninsula, Cornwall; Isles of Scilly
Comments: Significant H&S issues with survey for this species - best practise for cliff top sites to be strictly observed.
Key Action 2
Proposed Action: Autecological research to better characterise habitat requirements and inform management
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: Kynance Cove, Cornwall (Lulworth Cove, Dorset if it is rediscovered there (Action 1)
Comments: Focus on reliable and contrasting sites
Key Action 3
Proposed Action: Site management to include of scrub control with aftermath grazing to maintain short, open turf (particularly an issue in cliff top situations)
Action targets: 7. Best approach adopted at appropriate scales
Action type: Habitat management
Duration: >10 years
Scale of Implementation: ≤ 5 sites
High priority sites: Lulworth Cove, Dorset; Lizard peninsula, Cornwall; Isles of Scilly
Comments: Action likely to be integral to wider management objectives for site/s
