Before humankind started impacting the landscape and hunted animals intensively, all kinds of large grazers could be found in our ecosystem. Think of wild cattle and horses, roe deer, red and fallow deer, but also native species such as European bison and elk. Each species has a different diet and displays different behaviour. One species can even make an area better suitable to another species. Cattle, for example, thrive on high grass and rough terrain. Following in their footsteps are horses, whom like a more open landscape and shorter grass. But also less conspicuous herbivores have great influence on the diversity of nature and landscape. Think about caterpillars that defoliate forests and crops, grazing waterfowl that eat bare banks and beavers that gnaw down trees.
