Overview

Carex bicolor, the bicoloured sedge, is a species of sedge native to North America, Northern Europe and Northern Asia. The International Union for Conservation of Nature has assessed the plant's conservation status as being of least concern because it has a widespread distribution and faces no particular threats.

Bicoloured Sedge faces severe population declines primarily due to habitat loss and degradation of its specialized wetland environments. Climate change poses an additional threat by altering the hydrological conditions and temperature regimes essential for this arctic-alpine species.
