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
Meles (genus) has been much discussion as to whether it is a single species or three distinct species. There are geographical differences between individuals from different parts of the range in skull structure, morphology of the first premolar teeth, and facial markings. Some authorities advocated placing European and Asian badgers in separate species, "Meles meles" and "Meles leptorhynchus" (Milne-Edwards, 1867), the boundary between the two being the Volga River. Others considered there to be three subspecies, "M. m. meles", found west of the Volga, "M. m. arenarius-leptorhynchus", found between the Volga and Transbaikalia, and "M. m. amurensis-anakuma" from the Amur region and
