In 2003 the back-breeding project Projekt Urokse ('Project Aurochs') was initiated in Lille Vildmose, in which a crossbred population of Heck cattle, Chianina and Sayaguesa was released under controlled conditions and is being bred and selected for heightened similarity to the extinct aurochs in both morphology (looks) and instincts (behaviour).
