Overview

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

Yellow sedge faces severe decline due to widespread drainage and conversion of its wetland habitats for agriculture and urban development. Eutrophication from agricultural runoff and sewage discharge alters the nutrient-poor conditions this species requires, leading to competitive exclusion by more aggressive plant species. Climate change-induced shifts in precipitation patterns and increased drought frequency further threaten the hydrological stability of remaining suitable habitats.

Threat summary

Habitat

Yellow sedge inhabits nutrient-poor, calcareous wetlands including fens, wet meadows, marshes, and boggy areas with alkaline to neutral pH conditions. It typically grows in areas with fluctuating water levels and requires consistent moisture throughout the growing season.

Frequently asked questions

Why is Large Yellow-sedge classified as Endangered?
Large Yellow-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. Yellow sedge faces severe decline due to widespread drainage and conversion of its wetland habitats for agriculture and urban development. Eutrophication from agricultural runoff and sewage discharge alters the nutrient-poor conditions this species requires, leading to competitive exclusion by more aggressive plant species. Climate change-induced shifts in precipitation patterns and increased drought frequency further threaten the hydrological stability of remaining suitable habitats.
Where does Large Yellow-sedge live?
Large Yellow-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 Large Yellow-sedge?
The main threats to Large Yellow-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.
