Overview

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

Cerylon impressum faces severe threats primarily from habitat loss due to deforestation and forest degradation, which destroys the dead wood substrates essential for its survival. The species' specialized ecological requirements and limited dispersal ability make populations highly vulnerable to fragmentation and local extinctions. Climate change may further exacerbate these pressures by altering forest composition and moisture regimes critical for fungal decay processes.

Threat summary

Habitat

This species inhabits mature deciduous and mixed forests where it lives under the bark of dead and decaying hardwood trees, particularly favoring fungus-infected wood. It requires specific microhabitat conditions with appropriate moisture levels and fungal decay processes in fallen logs and dead standing trees.

Why is tallgångbagge classified as Critically Endangered?
tallgångbagge 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. Cerylon impressum faces severe threats primarily from habitat loss due to deforestation and forest degradation, which destroys the dead wood substrates essential for its survival. The species' specialized ecological requirements and limited dispersal ability make populations highly vulnerable to fragmentation and local extinctions. Climate change may further exacerbate these pressures by altering forest composition and moisture regimes critical for fungal decay processes.
Where does tallgångbagge live?
