The Taurus Project of the German Arbeitsgemeinschaft Biologischer Umweltschutz aims to re-create the extinct aurochs, the wild ancestor of domestic cattle, by cross-breedingHeck cattle (themselves bred in the 1920s and 1930s in an attempt to replicate the aurochs) with aurochs-like cattle, mostly from Southern Europe. Herds of these cross-bred Taurus cattle have been established in Germany, Denmark, Hungary and Latvia, and are used in conservation of natural landscapes and biodiversity.[1][2]
