Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Hydroporus longicornis remains widespread in the English uplands and is too frequent to consider it a national priority. However, as a species of natural seepages, lowland populations are at risk e.g. through over-abstraction of groundwater. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Hydroporus longicornis remains widespread in upland Britain and it is now accepted that it does not merit Nationally Scarce status in GB (Foster et al, 2020). Lowland sites are likely to be at greater risk but this could be mitigated by protection of groundwater-dependent habitats rather than species-specific measures. |
| 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: | N/A |
| Justification: |
