The largely abandoned quarry Gerhausen/Beiningen of HeidelbergCement AG is the home to many amphibians, birds, insects and rare plant species that need much warmth and light and therefore prefer an open landscape. To keep the vegetation low and preserve the character of the landscape special Taurus cattle graze here all over the year. Taurus cattle are an attempt of breeding back the aurochs, the wild ancestor of domestic cattle. Additionally, a small herd of Konik horses, a semi-feral horse breed, also help to prevent bush encroachment. Today, the quarry is a hotspot of biodiversity and a successful project in the open preservation of quarries. The grazing of the quarry is a joint project by the Building Material Association Baden-Württemberg e.V. and the UNESCO Global Geopark Swabian Alb.
