According to the local leader of "The Danish Nature Preservation Society", geologist "Jørgen Butzbach", there will not be done anything to preserve the cliff with the footprints. As time goes by the visible footprints will erode away, and new will surface.
The area was geologically seen, 144 million years ago (the early cretaceous period) a subtropical flood delta environment, containing areas with still waters with a high content of organic material.
It's possible to se fossilized, vertical burrows from freshwater lungfish, that lived at the sime time, as the sauropods left their footprints.

Ifølge den lokale formand for Danmarks Naturfredningsfoening Jørgen Butzbach gøres der intet for at bevare klinten. Med tiden vil denne blive nedbrudt af vejret, og nye fodspor vil dukke frem.
Området var geologisk set for 144 millioner år siden (tidlig kridttid) et subtropisk flod delta miljø, med områder med stillestående vand, der havde et højt indhold af organiske stoffer.
I umiddelbar nærhed af fodsporene kan man finde forstenede gravegange fra friskvands lungefisk, der levede samtidigt med de sauropoder, der efterlod sine fodspor.
