Large herbivore species like the aurochs, wisent, elk, and wild horse play an important role in the dynamics between fauna and flora and their grazing is recognized as essential for maintaining the biodiversity in open, park-like areas.
Therefore, their re-introduction into Europe's natural areas is deemed necessary, but some of these species are extinct in the wild.
[1] Stichting Taurus uses Exmoor ponies and Konik horses as large equine grazers.
[2] The robust grazers can survive without supplementary food during the winter and roam freely in the natural landscape of Keent the whole year.
[3] In the early 2000s Stichting Taurus instigated the Tauros Programme, which is a project attempting to breed a type of cattle which comes as close as possible to the extinct aurochs by crossbreeding and selecting the robust and aurochs-like cattle breeds.
