Norwegian specklebelly

Pseudocyphellaria norvegica

Unknown

Overview

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

The Norwegian specklebelly faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical balance of its substrate. Habitat fragmentation from forestry practices has reduced the availability of suitable old-growth forest environments. Climate change poses an additional threat through altered precipitation patterns and temperature fluctuations that affect the delicate moisture balance this lichen requires for survival.

Threat summary

Habitat

This foliose lichen inhabits the bark of old deciduous trees, particularly in humid, undisturbed forests with stable microclimatic conditions. It requires specific moisture levels and air quality, typically found in ancient woodland environments with minimal human disturbance.
