Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | While H. crenatus has a restricted range, probably for climatic reasons, it is not of high conservation concern. It can be abundant where it occurs, and it occurs relatively extensively outside the protected sites network. Like Enochrus nigritus (and possibly Limnebius aluta), it is one of the fenland specialities likely to benefit from the creation of new wetlands in the Fens and East Anglia. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Hydrochus crenatus would likely benefit from dissemination of generic good practice in managing Fenland drains, but it does not require species-specific conservation 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: |
