Overview

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

Tawny Sedge faces severe population declines due to widespread habitat loss from agricultural intensification, drainage of wetlands, and changes in traditional land management practices. The species' specialized requirements for calcium-rich, seasonally wet soils make it particularly vulnerable to hydrological changes and nutrient enrichment from agricultural runoff.

Threat summary

Habitat

Tawny Sedge occurs in calcium-rich wetlands including wet meadows, fens, dune slacks, and marshy grasslands that experience seasonal flooding. The species requires base-rich, nutrient-poor soils and benefits from light grazing or mowing that maintains open conditions.
