Since 2015 the epigael beetle population is monitored with the help_of Ground traps in the area around an inland dune in the vicinity of Lorsch, Southern Hesse, which is used as pasture for cattle from the Auerrind-Project of the Open Air Laboratory Lauresham. The results of this long time study are now presented in tabular form and discussed for the first time. This includes not only faunistic and ecological aspects, but also fundamental assessments about the completeness of beetle recording in the selected time span. Furthermore, additional surveys of the local bettle population, using different methods, are presented and evaluated.
