Summary Summaries of scientific research papers Vegetation in the environs of Pilviškiai The research had been performed in the summer of 2006 applying the route method. Natural communities had been described applying the principles of French-Swiss school of vegetation studies and classification as well as the methodology based on it. Later they were valued and habitats of European importance were distinguished according to the methods of determination of European important habitats. Pilviškiai area is notable for plain relief dissected by the Šešupė River and its tributaries. There are no primary untouched forests and wetlands at all. Now only some small plots of secondary forests (aspen or birch) are scattered among the cultivated fields or small arrays of black alder are in wetlands mainly along the rivers. Cultivated fields predominate, and biodiversity is low. All remaining natural, non-drained river valleys should be protected as valuable, because they contain smaller or larger plots of habitats of European importance, and there are conditions favourable for recovery of natural communities. The largest areas of natural meadow communities belonging to the habitats of European importance are met in: (a) Šešupė River valley at Pilviškiai (hydrophylous herb fringe communities, 6430; Northern Boreal alluvial meadows, 6450; and lowland hay meadows, 6510); (b) Jūrė meadows at Kriauniškė (Northern Boreal alluvial meadows, 6450; (c) Višakis meadows at Gabriškė and Mozūriškė (hydrophylous herb fringe communities, 6430; Northern Boreal alluvial meadows, 6450; and lowland hay meadows, 6510). daiva.patalauskaite@gmail.com
