In past centuries, the grazing of farm animals was one of the elementary pillars of biodiversity in today's cultural landscape. In their fur and hooves, even in their excrement, cattle, sheep or horses dispersed seeds, spores, fruiting bodies as well as small insects and beetles. They ensured the spread of a wide variety of plants and thus also the dense interconnectedness of these biotopes. The changeover to year-round livestock housing thus had a major influence on the decline in biodiversity.
