Hypolytrum subcompositus

Unknown

Overview

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

Hypolytrum subcompositus faces severe threats from agricultural expansion and urban development across its limited range in Southeast Asia. The species' specialized wetland habitat requirements make it particularly vulnerable to drainage and conversion of freshwater swamps for rice cultivation and aquaculture. Climate change-induced alterations to precipitation patterns further threaten the delicate hydrological balance these sedges require for survival.

Threat summary

Habitat

This critically endangered sedge inhabits freshwater swamps, marshy areas, and seasonally flooded grasslands in tropical lowland regions. It requires specific hydrological conditions with consistent moisture levels and is typically found in areas with organic-rich soils and partial shade.
