Overview

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

Sharp-flowered Rush faces severe threats from wetland habitat destruction and degradation due to agricultural intensification, drainage projects, and urban development. Climate change-induced alterations to hydrological regimes and increased frequency of extreme weather events further compromise the specialized acidic wetland conditions this species requires for survival.

Threat summary

Habitat

Acidic wetlands, marshy grasslands, bog margins, and wet heathlands, typically in areas with nutrient-poor, waterlogged soils. The species is particularly associated with seasonally flooded depressions and the edges of ponds, streams, and ditches in moorland and upland regions.
