Abstract

Black and white aerial photographs from 1947-1963 and colour, mainly infrared aerial photographs from 1996-2000 were used to study quantitative vegetation changes in 7 large lakes : Kemijärvi, Unnukka, Kallavesi, Päijänne, Näsijärvi, Pyhäjärvi and Vanajavesi. Vegetation changes were evaluated by comparing the situation before large-scale water level regulation and eutrophication to the current situation. The results point out the crucial impact of changing water levels and the significance of the surrounding soils to the cover of emergent aquatic vegetation
