Variegated sedge

Carex stylosa

Unknown

Overview

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

Carex stylosa faces severe population decline primarily due to wetland drainage and agricultural conversion of its specialized bog and fen habitats. Urban development and infrastructure projects have fragmented remaining populations, while altered hydrology from nearby land use changes disrupts the precise water table conditions this sedge requires. Climate change poses an additional threat through shifting precipitation patterns that could dry critical wetland sites.

Threat summary

Habitat

Carex stylosa inhabits specialized wetland environments including calcareous fens, alkaline bogs, and wet meadows with consistent groundwater seepage. This sedge requires specific hydrological conditions with stable water tables and mineral-rich soils, typically found in undisturbed wetland complexes.

Frequently asked questions

Why is Variegated sedge classified as Endangered?
Variegated sedge is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Carex stylosa faces severe population decline primarily due to wetland drainage and agricultural conversion of its specialized bog and fen habitats. Urban development and infrastructure projects have fragmented remaining populations, while altered hydrology from nearby land use changes disrupts the precise water table conditions this sedge requires. Climate change poses an additional threat through shifting precipitation patterns that could dry critical wetland sites.
Where does Variegated sedge live?
Variegated sedge occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Variegated sedge?
The main threats to Variegated sedge are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
