Overview

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

Hieracium psiloloma faces severe threats from habitat destruction and fragmentation in its extremely limited range. The species is vulnerable to invasive plant species that outcompete it for resources and alter soil conditions. Climate change poses additional risks through altered precipitation patterns and temperature regimes that may exceed the species' narrow ecological tolerances.
