Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Northern Clubrush faces severe decline due to habitat degradation from agricultural intensification and drainage of wetland areas across its limited range. Climate change poses an additional threat by altering the hydrology of the specialized bog and fen ecosystems this species requires. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction and changes in water table levels.

Threat summary

Northern Clubrush inhabits acidic bogs, fens, and wet moorlands, typically growing in nutrient-poor, waterlogged soils with consistent moisture levels. The species is found in montane and sub-arctic wetland ecosystems, often associated with Sphagnum moss communities and other specialized bog vegetation.
