Felwort Rust

Uromyces gentianae

Unknown

Overview

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

Felwort Rust faces severe decline due to the loss of its specialized host plants, particularly gentian species, through habitat degradation and agricultural intensification. Climate change poses an additional threat by altering the delicate moisture and temperature conditions required for both the fungus and its host plants to thrive. The species' highly specialized parasitic relationship makes it extremely vulnerable to any disruption affecting gentian populations in alpine and subalpine grasslands.

Threat summary

Habitat

Felwort Rust is found exclusively in alpine and subalpine grasslands where its host gentian species grow, typically at elevations between 1,000-2,500 meters. The fungus requires the specific microclimate conditions of these montane environments, including cool temperatures, high humidity, and the presence of healthy gentian populations.
