Walking in ancient hoof prints

Such an animal has not been seen on Czech territory for hundreds of years. A Dutch breeding program has recreated massive bovines closely related to aurochs, once the heaviest European land mammal and the wild ancestor of today’s cattle that became extinct in the 17th century. It is believed they disappeared from what is now the Czech Republic in the 12th or 13th century. On Tuesday, a small herd was introduced to a Czech sanctuary as part of a project to use big-hoofed animals to maintain the steppe character of the former Milovice military base, 22 miles northeast of Prague. The beasts joined a herd of 15 wild horses from Britain’s Exmoor National Park that were moved here in January with a task to stop the spread of aggressive and evasive grasses and bushes, delicacies to the animals. The invasive plants began to grow after Soviet troops withdrew from the base in 1991, threatening the area’s original plants and animals. After a nine-hour drive and few more minutes of hesitation, five cows and a bull — all calves— jumped out of a truck at dawn to take the first look at their new home. The Dutch Taurus Foundation joined forces with the University of Wageningen and some other groups in the Tauros program, as the new animal is called, in 2008. With knowledge of the aurochs’ DNA, the scientists analyzed some existing primitive cattle breeds that are similar to their extinct ancestors. They included Pajuna, Sayaguesa and Limia from Spain, Maremmana from Italy and Highlander from Scotland. Through cross-breeding, they have been working on reconstructing the original aurochs with the goal to have “the presence of the Tauros as a self-sufficient wild bovine grazer in herds of at least 150 animals each in several rewilding areas in Europe,” Rewilding Europe, another organization involved, said on its Web site. “In a few generations, we should be able to get an animal that looks like the aurochs and also has the same impact on the environment,” Dostal said...more
