Field Study in Entlebuch

As another potential reference biotope, I chose the mountainous region of Entlebuch (ca. 46º 53' N/8º 0' E to 46º 48' N/7º 56' E) in Central Switzerland, which had been approved in 2001 by UNESCO (United Nations Educational, Scientific and Cultural Organization) as the first Swiss Biosphere Reserve. A total of 18 different locations were chosen according to topographic criteria, lying within an area of ca. 12 × 16 km. Per study site, 65 true bugs were collected. In spite of sustainable cultivation, the Entlebuch true bugs are endangered. In the North there are 4 nuclear power plants and one nuclear research palnt, Paul Scherrer Insitute PSI located. PSI houses a oven for the burnig of nuclear waste.
It seems that the emitted artificial radiation causes the disturbances.
