It can be concluded that the inertia in the response processes following changes in a given habitat and at a given site may distort the picture of species of plants and invertebrates expected to be present at the site or in the habitat. With an increase in field size, the actual amount of non-arable, small-scale habitats such as field edges, hedges and wild corners of the fields will decrease. Together with other small-scale farmland habitats, field edges, hedges and field corners that are left without regular cultivation make up a network of small, natural habitats that have profound effect for the occurrence and distribution of biodiversity in the farmland landscape.
