Sheeps play a key role in maintaining the biodiversity. Indeed, the landscapes have been shaped by their presence and their needs in grazing areas and in mowing meadows. The environment has gradually evolved, the large forests have lost in land by giving way to grasslands and biodiversities. Today, without pastoralism, the areas tend to close up and lose their diversity. Careful, excessive exploitation also causes a decrease in biodiversity. A good organization of pastures requires regular monitoring and respecting the life cycle of plants.
