Schoenoplectiella perrieri

Declining

Overview

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

Schoenoplectiella perrieri faces severe threats from habitat destruction due to wetland drainage and conversion for agricultural use across its limited range in Madagascar. Urban development and infrastructure projects have further reduced available habitat, while invasive plant species compete for resources in remaining wetland areas. Climate change-induced alterations to precipitation patterns threaten the specific hydrological conditions this sedge requires for survival.

Threat summary

Habitat

This critically endangered sedge is endemic to Madagascar's freshwater wetlands, including marshes, swamps, and seasonal pools. It typically grows in shallow water or saturated soils with specific hydrological requirements that make it highly vulnerable to environmental changes.

Schoenoplectiella perrieri is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Schoenoplectiella perrieri faces severe threats from habitat destruction due to wetland drainage and conversion for agricultural use across its limited range in Madagascar. Urban development and infrastructure projects have further reduced available habitat, while invasive plant species compete for resources in remaining wetland areas. Climate change-induced alterations to precipitation patterns threaten the specific hydrological conditions this sedge requires for survival.
Where does Schoenoplectiella perrieri live?
Schoenoplectiella perrieri occurs in Madagascar. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Schoenoplectiella perrieri?
The main threats to Schoenoplectiella perrieri are 11.1, 2.1, 5.3, and 7.2. The full IUCN-classified threat record for this species is detailed on the species page.
