Klonk is represented by red fox ("Vulpes vulpes)", European badger ("Meles meles"), wood mouse ("Apodemus sylvaticus") and other, usually common species. The goal of the protection plan is to secure the important geological profile and preserve it for future study. Klonk is mainly threatened by amateur palaeontologists who expect a rich locality, however the location is important mainly due to microfossils. Another threat is the overgrowing of vegetation, which has been successfully removed mechanically and by herbicides in the past. The removal of unwanted vegetation should also help the return of the original vegetation, which used to be strongly influenced by
European land mammal age young). European Land Mammal Mega Zones most often have their bases at first appearances (FAD, First Appearance Date) of a certain species or genus. The numbers are higher for younger zones. Due to a redefinition of the boundary between the Neogene and Quaternary periods, MN 17 is now in fact considered a Quaternary biozone. European land mammal age The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of European land mammals.
