Coverage and depth limit of macrophytes as tools for classification of lakes; 124–140

Helle Mäemets, Lilian Freiberg
The aim of the study was to clarify the applicability of total coverage percentage of macrophytes and depth limit of submerged plants for the quality estimations of Estonian lakes. Total coverage does not seem to be correlative with lake quality. The depth limit of submerged plants appears to be a better characteristic of the state of small lakes, and is relatively well correlated with water transparency, less with chlorophyll a content. In large L. Peipsi the mean of macrophyte depth limit would be a better characteristic than single maximum values.
