Overview

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

Farnoldia jurana faces severe threats from air pollution and acid rain, which degrade the specific chemical conditions required for this crustose lichen's survival on limestone substrates. Climate change is altering precipitation patterns and temperature regimes in its montane habitats, while quarrying and development activities continue to destroy the calcareous rock formations it depends upon.

Threat summary

Habitat

This crustose lichen grows exclusively on calcareous rocks and limestone substrates in montane and subalpine regions, typically found on exposed cliff faces, rocky outcrops, and limestone pavements at elevations between 800-2000 meters.

Frequently asked questions

Why is farnoldia lichen classified as Critically Endangered?
farnoldia lichen is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Farnoldia jurana faces severe threats from air pollution and acid rain, which degrade the specific chemical conditions required for this crustose lichen's survival on limestone substrates. Climate change is altering precipitation patterns and temperature regimes in its montane habitats, while quarrying and development activities continue to destroy the calcareous rock formations it depends upon.
Where does farnoldia lichen live?
farnoldia lichen occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to farnoldia lichen?
The main threats to farnoldia lichen are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
