Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | No |
| Justification: | Regionally Extinct. In Britain Obrium cantharinum was primarily found in the region north of the River Thames including Epping and Hainault Forests, Wanstead Park and Dagnam Priory. It has not been reported since the 1920s. The species has been assessed as Least Concern at a European level and the UK is the only country where it has become extinct. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | The species has been assessed as Least Concern at a European level and the UK is the only country where it has become extinct. Given that it has not been recorded even as a vagrant in 100 years, it may be unlikely to naturally recolonise Britain from the continent. |
| 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 |
