Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Slender Cottonsedge faces severe decline due to widespread drainage and conversion of its specialized wetland habitats for agriculture and development. Climate change compounds these pressures by altering precipitation patterns and increasing temperatures, which disrupts the delicate hydrology of peat bogs and fens essential for the species' survival. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural recolonization of suitable sites.
Habitat
Slender Cottonsedge inhabits acidic peat bogs, calcareous fens, and wet meadows across northern temperate regions, requiring consistently waterlogged soils with specific pH conditions. The species thrives in open, nutrient-poor wetlands where competition from other vegetation is limited by the harsh growing conditions.
