Puccinia arctica

Local name: finnmarksnøkleblomrust

Unknown

Overview

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

Puccinia arctica faces severe threats from climate change as Arctic warming reduces suitable habitat for both the fungus and its host plants. The species' restricted range in high-latitude environments makes it particularly vulnerable to temperature increases that alter the delicate ecological balance required for its parasitic lifecycle. Habitat degradation from increased human activity in Arctic regions and potential changes in host plant communities further compound these pressures.

Threat summary

Habitat

This Arctic rust fungus inhabits high-latitude tundra environments, parasitizing specific host plants in cold, northern ecosystems. It is adapted to the extreme conditions of Arctic and subarctic regions where temperature and seasonal patterns are critical for its reproductive cycle.
