Stock Photo - Not only wild horses, but newly also aurochs are grazing on grass at the former Czech military training grounds in Milovice to which they were released today, on Tuesday, October 13, 2015. The aurochs were brought to an acclimatisation enclosure where they will stay for a month and then will be released to a 40-hectare area where a herd of 15 wild horses has already been for several months. Together, the animals will help maintain the pastures with rare species of plants and butterflies. Thanks to the horses and aurochs the pastures are to be grazed in a combined way. The horses mostly graze on the grass, while the aurochs prefer the naturally regenerated evergreen tree species and plants that are avoided by the horses. This will create good conditions for the appearance of rare plants such as star gentian (Gentiana cruciata) and the rare butterfly Mountain Alcon Blue (Phengaris rebeli). The aurochs are bred back because the original aurochs became extinct in the 17th century, in the Czech Lands as early as the 12-13th century. In prehistory, the aurochs ranged across much of Europe and Asia. The Dutch Taurus Foundation has been working on breeding back a type of aurochs from similar species of cattle since 2008. The back-bred aurochs in Milovice will be the first herd in central and eastern Europe. A bull and five young heifers were brought in a lorry from the Netherlands. (CTK Photo/Vit Simanek)
