The project was founded in 2008, and the actual breeding program started the following year.
Background
In line with the
wood-pasture hypothesis, herbivorous
megafauna are considered important tools of
nature conservation in maintaining the biodiversity of open or park-like landscapes without human interference. Therefore, it is planned to reintroduce large game in several reserves to recreate the natural dynamics of the European ecosystems. The aurochs was one of the most important European

Highland cattle. Heck cattle originated in the 1920s as an attempt by
Lutz and
Heinz Heck to breed an aurochs look-alike from several cattle breeds. Heck cattle turned out to be a hardy breed, but are found to be considerably different from the aurochs in several aspects.
The Tauros Programme is one of several
breeding back attempts. This is based on the idea that original features of the aurochs are still present in some less-derived cattle breeds and can be reunited by crossbreeding and selective breeding. Stichting Taurus has been running grazing projects with hardy cattle and horses for years and purchased cattle breeds they consider to be useful for the project from southern Europe.
Methods and goal
Tauros programme uses very hardy cattle breeds, which should preferably resemble the aurochs to a useful extent. Crossbreeding and selective breeding with such breeds should create new lineages which are hoped to come close to the aurochs as much as possible and are fit for being released in European wild reserves. Not only the phenotype and robustness are in the focus of breeding, but also genetic information of the aurochs which might be preserved in these breeds is considered.
There are variations within each breed, so selection criteria are necessary to select the individuals to be included on the project. Accordingly, studies are running parallel under the umbrella of the project, e.g., to evaluate possible

Lidia breed (Spanish fighting bull) was not used for the project due to its aggressive behaviour.
These primitive breeds have decreased in numbers during the last decades, and some are highly endangered. Scottish
highland cattle are used as well, because this breed has a long and dense coat and is very hardy. Several cross individuals have been born already.
Members of the project hope that the Tauros cattle will one day be able to move freely in wild herds in European nature areas just as
