This year the 12th "GeoTag der Artenvielfalt" took place. Nationwide full-time and volunteer called environmentalists and experts on the local flora and fauna met to explore and list the species inventory of a selected habitat.

Also Norbert Hecker, Uwe de Bruyn und Dr. Jörg Petersen set out on the search.
