Scolytus triarmatus
Local name: större almsplintborre
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Scolytus triarmatus faces severe population decline primarily due to the widespread loss and degradation of mature elm forests across its range. The species' specialized dependence on large, healthy elm trees makes it particularly vulnerable to Dutch elm disease, which has devastated elm populations throughout Europe. Urban development and intensive forestry practices have further reduced suitable breeding habitat, while climate change may be altering the distribution and health of its host trees.
Habitat
This bark beetle species inhabits mature elm forests and woodland edges where it breeds exclusively in the bark and wood of elm trees (Ulmus species). The species requires large, healthy or recently dead elm trees for successful reproduction and larval development.
