02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Stor barktæge (Aradus conspicuus) faces severe population declines due to habitat loss and degradation of its specialized bark beetle-dependent ecosystems. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to forest fragmentation and changes in host tree availability.
