Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | While it has a restricted distribution, there is no evidence of a loss of range and E. nigritus is likely benefiting from wetland restoration in Fenland. It can be abundant where it occurs. This species is capable of at least localised dispersal, so has the potential to colonise new habitats close to existing centres. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | While this species is not a conservation priority, E. nigritus is one of the high quality fen species which could potentially colonise new and restored wetlands in Cambridgeshire and Norfolk. Monitoring of aquatic invertebrate assemblages at such sites should be encouraged. |
| 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: |
