WARNING: Accuracy of Data: The information contained in this mapping tool, has been compiled from both published historic records of dung beetle distribution and observations from experts associated with the DBEE project. The map shows where the selected introduced dung beetle has been found in Australia at the level of Natural Resource Management (NRM) units. The absence of a dung beetle specie in a particular NRM may reflect a lack of collecting effort rather than true absence of a species and species may not be present across an entire NRM.
