W sezonach wegetacyjnych 2002-2005 przeprowadzono interdyscyplinarne badania 30 zróżnicowanych morfometrycznie jezior, zlokalizowanych na Pojezierzu Lubuskim. Celem badań było określenie stopnia zróżnicowania badanych jezior na tle udziału powierzchniowego oraz liczby zbiorowisk charofitów jak również ich znaczenia w ocenie stanun ekologicznego.

In the vegetation seasons 2002 - 2005 multidisciplinary investigations of 30 lakes located on Lubuskie Lakeland (mid-Western Poland) were carried out. The aim of this paper, based on the above studies, was to characterize the significance of charophytes in the differentiation of investigated lakes and their applicability in the ecological status assessment as well. To characterize the differentiation of studied lakes against the background of analyzed properties principal component analysis (PCA) was undertaken. The results demonstrated that charophytes significantly differentiated among the lakes studied. Visibly better habitat conditions as well as lower biomass of pelagic phytoplankton were found in lakes with abundant and diverse charophyte vegetation. Lakes with poorly developed or without charophytes were characterized by significantly worse habitat conditions and higher biomass. Moreover it was assumed that interrelationships between the charophyte coverage and phytoplankton biomass and visibility can play a significant role in functioning of lakes and their ecological status assessment.
