Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Apart from a single Scottish location, D. anglicanus is confined to relict-fens in Cambridgeshire and East Anglia. Recorded from 16 English hectads since 1980. Due to the difficulties in assessing historic records of Dryops species, there is no clear indication of population trends. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Its dependence on fens of natural origin and presumed lack of dispersal capability make this species inherently vulnerable. Dryops anglicanus is probably confined to protected sites and shares requirements in common with other relict-fen water beetles but it cannot be assumed that site managers/stakeholders are aware of these. |
| 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 is too rare and localised to benefit from generic measures; it has a highly restricted distribution and is dependent on relict fens. Generic guidance on pond management/restoration may not be appropriate where this and other species of richly-vegetated seasonal pools are present. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 4. Autecology and pressures understood |
| Recovery potential/expectation: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Ad hoc recording as part of GB water beetle recording scheme (Balfour-Browne Club/Aquatic Coleoptera Conservation Trust). |
Key Actions
Key Action 1
Proposed Action: Make an inventory of all protected sites with post-1980 records. Consider opportunities for listing this species as a site 'feature' (e.g. review of SSSI citations).
Action targets: 5. Remedial action identified
Action type: Site protection
Duration: 2 years
Scale of Implementation: National
High priority sites: In England, D. anglicanus is confined to East Anglia.
Comments: Relevant to all sites in inventory.
Key Action 2
Proposed Action: Undertake a review of this species and other water beetles dependent on relict-fens in order to promote better understanding of their conservation requirements. D. anglicanus belongs to a suite of water beetles closely associated with remnant fens; others include Agabus striolatus, D. auriculatus, D. griseus, Helochares obscurus, Hydrochus brevis, H. ignicollis, H. megaphallus, Hydroporus elongatulus, H. glabriusculus, H. scalesianus, Laccornis oblongus and Limnebius aluta.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 1 year
Scale of Implementation: National
High priority sites:
Comments:
Key Action 3
Proposed Action: Advise site managers on the presence and requirements of this species in consideration of SSSI, nature reserve management, and other land management, especially pond restoration and water level control.
Action targets: 5. Remedial action identified
Action type: Advice & support
Duration: 2 years
Scale of Implementation: National
