Cyperus mangarevica

Declining

Overview

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

Cyperus mangarevica faces severe threats from invasive plant species that outcompete native vegetation and alter soil chemistry in its limited habitat range. The species' restriction to specific wetland microsites on Mangareva Island makes it particularly vulnerable to habitat degradation from human activities and introduced herbivores. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate hydrological balance required for this sedge's survival.

Threat summary

Habitat

This endemic sedge inhabits freshwater wetlands, marshy areas, and seasonally flooded depressions on Mangareva Island in the Gambier Islands of French Polynesia. It requires specific soil moisture conditions and is typically found in areas with consistent water availability throughout the year.
