Overview

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

Skør kuglelav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds, which dramatically alter the chemistry of its substrate and surrounding environment. Climate change compounds these pressures by creating conditions that favor competing species and alter the delicate moisture regimes this sensitive lichen requires. Habitat fragmentation and loss of suitable old-growth forest stands further restrict available colonization sites.

Threat summary

Habitat

This species occurs on bark and wood of old trees in mature, humid forests, particularly favoring acidic substrates in areas with clean air and stable moisture conditions. It is typically found in undisturbed coniferous and mixed forests where air quality remains high and atmospheric pollution is minimal.

Why is Skør kuglelav classified as Critically Endangered?
Skør kuglelav 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. Skør kuglelav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds, which dramatically alter the chemistry of its substrate and surrounding environment. Climate change compounds these pressures by creating conditions that favor competing species and alter the delicate moisture regimes this sensitive lichen requires. Habitat fragmentation and loss of suitable old-growth forest stands further restrict available colonization sites.
Where does Skør kuglelav live?
Skør kuglelav 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 Skør kuglelav?
The main threats to Skør kuglelav 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.
