Carex austromexicana

Unknown

Overview

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

Carex austromexicana faces severe threats from agricultural expansion and livestock grazing in its restricted montane habitat range in Mexico. Urban development and infrastructure projects continue to fragment the remaining populations of this critically endangered sedge. Climate change poses an additional threat as warming temperatures may push suitable habitat to higher elevations beyond the species' current range limits.

Threat summary

Habitat

This sedge species inhabits high-elevation montane grasslands and meadows in the mountains of central Mexico. It typically grows in moist, well-drained soils at elevations between 2,500-3,500 meters in areas with seasonal rainfall patterns.
