Jamesonia hirta

Unknown

Overview

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

Jamesonia hirta faces severe threats from habitat destruction due to agricultural expansion and livestock grazing in its restricted high-altitude range. Mining activities and infrastructure development further fragment its already limited páramo habitat. Climate change poses an additional threat as warming temperatures force this cold-adapted fern to retreat to increasingly smaller areas at higher elevations.

Threat summary

Habitat

This critically endangered fern is endemic to high-altitude páramo ecosystems in the Andes, typically found in moist, rocky crevices and slopes between 3,000-4,200 meters elevation. It requires the specific cool, humid conditions of these montane grasslands and shrublands.
