Cyperus gigantobulbes

Unknown

Overview

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

Cyperus gigantobulbes faces severe threats from agricultural expansion and urban development across its limited range in Madagascar. The species' specialized wetland habitat requirements make it particularly vulnerable to drainage and conversion of seasonal pools and marshy areas. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while invasive plant species compete for resources in degraded areas.

Threat summary
