We studied this question in 2016/2017 by sampling Invertebrates on six meadows and collected more than 147.000 specimens.
The results of this study are summarized hiere:DOWNLOAD
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.
The Styrian government - A13 has contracted us to study the distribution and densities of the Otter in Styria, in co-operation with Steven Weiß (University Graz, Institute for Biology).
