Changes in the Dutch ‘wild’ flora have been studied by analysing data from the Standard List 1990. For each taxon data are available in this List about the frequency (UFK) in 1940 and 1990, ecological group and the category of the Red Data List. A trend is visible that common species are becoming more common and that rare species are becoming more rare. The floristic decline affects the chalk-rich and nutrient-poor habitats, the progress concerns the nutrient-rich habitats.
