Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: 44 post-1980 hectads in England with 2 more in S Wales (Foster et al, 2018). It has been lost from most of its historic inland locations in E England but there are remaining strongholds on coastal levels in E Anglia, the south-east and on the Somerset Levels. Its fate is closely linked to that of Coastal & Floodplain Grazing Marsh priority habitat.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: No
Justification: Most of the habitats occupied by L. niger have been well surveyed in recent years. Current levels of ad-hoc recording are probably proportionate to its status at present; this should be reviewed if evidence of ongoing decline is forthcoming.
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
