Saproxylic Insects in the Gesäuse National Park
Half of the Gesäuse National Park is covered by forests. In co-operation with Erwin Holzer and Carsten Morkel, we studied saproxylic beetle and Aradidae bug species in the National Park and identified the most important forests sites for biodiversity conservation issues.
Using window traps on 30 sites, we collected 1553 beetles from 231 species (Ø 15-30 species/site). Decidous forests north of the Enns river showed the highest species diversity. We also found eight aradid bugs and a very rare, saproxylic planthopper. Their presence is dependant upon higher amounts of deadwood.
To further enhance biodiversity, we recommend to leave any dead wood (also after catastrophic events) untouched.
