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 hedgehog days they can roll into a ball. Weaning occurs at four to six weeks of age. European hedgehogs may live to ten years of age, although the average life expectancy is three years. Starvation is the most common cause of death, usually occurring during hibernation. If alarmed, the animal will roll into a ball to protect itself. Many potential predators are repelled by its spines, but predation does occur. Remains of hedgehogs have been found in the stomachs of European badgers ("Meles meles"), red foxes ("Vulpes vulpes") and pine martens ("Martes martes"). A large portion of these may be from
