Toelichting (Engels) An inventory of the desmid flora in a number of forest and moorland pools, carried out in I975, revealed that an appreciable impoverishment has occurred since the turn of the century. In those pools which are immediately surrounded by arable land and pastures or are connected with cultivated areas by small streams, the deterioration is caused by eutrophication and pollution of the aquatic environment. ln hydrologically isolated pools, situated within nature reserves, the decline must be attributed to an acidification and oligotrophication of the site. The latter phenomenon may be associated with a much increased acid deposition in the atmospheric precipitation owing to air pollution, as recorded in the Netherlands especially in the last decennia.
