| Qualifying criterion: 4.4: very rare (less than 5 sites) with evidence of ongoing threat |
| Justification: formerly submerged within B. regius, there is need for continuing BAP action that has been applied previously to B. regius |
| Threats: habitat destruction (particularly in the New Forest by clearance of trees from around old marl pits); trampling, compaction, biking, eutrophication, overgrowth |
| Action Required: site protection and monitoring against habitat loss and degradation; taxonomic research; liaison with site managers |
