| 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: | Anthogona britannica |
| UKSI Recommended Authority: | Gregory, Jones & Mauriès, 1993 |

Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | NT, may be frequent at sites within a restricted area of S. Devon but is endemic to England |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Restricted range for reasons that need to be determined |
| 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: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | First described in 1993 and probably overlooked as juveniles of a larger species in the past |
Key Actions
Key Action 1
Proposed Action: Determine precise distribution by extending searches for millipede to east and to west of known range along South Devon coast and inland from this area. Extend survey to coasts of Cornwall and Dorset in second year.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: ≤ 50 sites
High priority sites: Devon and Cornwall
Comments:
Key Action 2
Proposed Action: Autecological research to better characterise habitat requirements. Sufficient data is expected from action one to confirm and refine provisional view of habitat requirements.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 2 years
Scale of Implementation: ≤ 10 sites
High priority sites: Devon and Cornwall
Comments: Data will be collected alongside survey in action one but repeat visits to at least some sites may be required
Key Action 3
Proposed Action: Assess potential for assisted colonisation of sites on nearby stretches of coast if new populations are not found there. Identify 3-5 locations where, based on results of action 2, the habitat appears suitable for colonisation by the millipede
Action targets: 5. Remedial action identified
Action type: (Re-)introduction
Duration: >10 years
Scale of Implementation: ≤ 5 sites
High priority sites: Devon and Cornwall
