Cyperus multifolius

Unknown

Overview

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

Cyperus multifolius faces severe threats from urban development and agricultural expansion across its limited range in Madagascar. The species' wetland habitats are being drained and converted for rice cultivation and human settlement, while invasive plant species compete for resources in remaining suitable areas. Climate change poses additional pressure through altered precipitation patterns affecting the seasonal flooding cycles essential for this sedge's reproduction.

Threat summary
