[3] The Hundsheimer Berge form an island in the flat agricultural landscape of Lower Austria.

These rocks that are prone to karst influences, in combination with the very thin humus layer, create a very dry environment on the steep slopes of the Hundsheimer Berge.

[4] Approximately 1350 species of Micro- and Macrolepidoptera have been found in the Hundsheimer Berg nature reserve.

The remaining 1315 species represent almost 40% of the total butterfly and moth fauna of Lower Austria.

[3] Other notable animals are Saga pedo, European ground squirrel, Setina roscida and species of Megachile.
