Schoenoplectiella aberrans

Declining

Overview

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

Schoenoplectiella aberrans faces severe threats from wetland habitat destruction and degradation across its limited range. Urban development and agricultural expansion have eliminated many of the specialized freshwater marsh environments this sedge requires. Water pollution from agricultural runoff and urban discharge further degrades remaining habitat quality, while altered hydrology from dam construction and water diversions disrupts the natural flooding cycles essential for the species' reproduction.

Threat summary

Habitat

This critically endangered sedge inhabits freshwater marshes, shallow wetland margins, and seasonally flooded grasslands. It requires specific hydrological conditions with periodic flooding and drawdown cycles typical of natural wetland systems.

Frequently asked questions

Why is Schoenoplectiella aberrans classified as Critically Endangered?
Schoenoplectiella aberrans 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 aberrans faces severe threats from wetland habitat destruction and degradation across its limited range. Urban development and agricultural expansion have eliminated many of the specialized freshwater marsh environments this sedge requires. Water pollution from agricultural runoff and urban discharge further degrades remaining habitat quality, while altered hydrology from dam construction and water diversions disrupts the natural flooding cycles essential for the species' reproduction.
Where does Schoenoplectiella aberrans live?
Schoenoplectiella aberrans 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 aberrans?
The main threats to Schoenoplectiella aberrans are 2.1, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
