In this way extensive permanent grassland and, therefore, new habitats for many species can be created from intensively used areas. Whether fertiliser nor pesticides are applied. The soil is not tilled anymore so that humus can form. Consequenlty, over-fertilised or depleted soils and the groundwater can recover. Furthermore, the ground is complety planted with regional plant species, which attracts animals, especially inspects. Humans seldomly set foot on the areas so flora and fauna can grow without much interference. Only two times a year the maintenance team visits the plant and uses mineral-fortified and, therefore, water permeable paths to get to the modules.
