Material collected during the years 1995–2011 was used to describe the distribution and environmental preferences of charophyte species in Estonian lakes and its coastal Baltic Sea. Altogether 22 species of charophytes were found in Estonian waters

We have compared the floristic composition of managed (M) and wild (W) shore areas in the northwestern, eutrophic part of Lake Peipsi (3555 km 2 , with unregulated water levels). Management techniques include uprooting or cutting of reeds and willows

We made use of a 22-year (1985–2007) retrospective archive of moderate resolution Landsat TM and ETM+ satellite images to estimate the changes in cover of emergent macrophytes in the large shallow eutrophic Lake Vortsjarv (270 km 2 ) in Estonia. An

We present an overview of long-term changes in the floristic composition and growth areas in L. Peipsi (3555 km 2 , unregulated water level) that have occurred since the 1960s and a list of plant taxa containing 140 species of higher plants and 4 cha

The Water Framework Directive (WFD 2000) defines macrophytes as one of the biological groups required for the ecological assessment of European surface waters. For the first step of the intercalibration exercise on the different existing macrophyte a

Yearly differences in the composition and nutrient content of submerged macrophyte stands, mainly of the long-term dominant Potamogeton perfoliatus L. were observed at 10 stations along 83 km route of the Estonian shore of L. Peipsi (total area 3555
