Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Provisional England LC, Britain LC (Stewart & Lansdown 2021, Stewart 2022). Currently increasing but still problems with nutrient impacts |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | No |
| Justification: | Largely constrained by nutrient enrichment problems. In the Norfolk Broads may also affected by boat traffic, cutting, loss of underwater topographic structure (too much soft organic silt) but maybe less so than other stonewort species. |
| 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 |
