The main threat to the beaked rush is habitat loss which is thought to have reduced various populations. Conversion of previously suitable habitat for agriculture, wetland drainage, peat extraction and afforestation have all contributed to the decline of this species throughout its range (5) (6) and have resulted in some populations becoming fragmented. Succession and detrimental forest management practices may have also negatively affected certain populations (6).
Climate change may pose a threat to the beaked rush in the future. This species requires wetland habitats which may begin to desiccate as weather patterns change (6).
