La vegetazione della Riserva Naturale “Lago di Biandronno” (Lombardia, Italia Settentrionale).

The vegetation of Natural Reserve “Lago di Biandronno” (Lombardy, Northern Italy). This study investigates the vegetation of Natural Reserve “Lago di Biandronno”, mire near by LakeVarese. Main eight groups of vegetations are recognized and ascribed to six phytosociological classes (Alnetea, Lemnetea, Molinio-Arrhenatheretea, Oxycocco-Sphagnetea, Potametea e Phragmiti-Magnocaricetea). The main ecological factor is the water table-pH gradient, with the latter strongly influenced by Sphagnum species. The ecological dynamic moves in two different ways that are directed towards Alnus woods. The fire affects the vegetation and in particular supports the growing of Phragmites and the alien Solidago gigantea.
