To judge the extent of anthropogenic impacts on the natural environment, it is important to choose an animal group which is able to reflect this reality and can indicate this influence over a long geological time. Molluscs correspond excellently with these demands. Through studing malacofauna, changes in malacoenoses or in individual populations can be traced from the Quaternary to the Holocene. As a basis of analysis, in determining the ecological stability of an area, maps of chosen species distribution (bioindicators) are used, from which it is then possible to create a map showing the occurrence of endangered and rare species. Land is differentiated into categories with the help of malacofauna which adequately reflect the state of preservation. The areas which are originally preserved or in which the natural conditions are near to the potential belong in the gene pools. These are becoming a part of gene pool areas with the primary aim of preserving biodiversity
