Cyperus grandifolius

Declining

Overview

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

Cyperus grandifolius faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range. Wetland drainage and water diversion projects have eliminated critical marsh habitats where this sedge historically thrived. Climate change-induced alterations to precipitation patterns further threaten the specific hydrological conditions this species requires for survival.

Threat summary

Habitat
