The pH history of Huzenbachersee in the northern Black Forest has been studied by using diatom records of a long core and a short core. The results reveal that the pH of the lake has decreased by 1 unit since the end of the ice age until circa 1800, owing to natural long‐term acidification. The impact of man in the last 200 years, such as catchment afforestation and especially acid deposition, have caused additional dramatic pH declines in a very much shorter period of time.
