Abstract
Sovsko lake lies on the northern slope of Dilj-gora. It is an example of a natural lake in the mountainous hilly region of inland Croatia. Its area is around 3,6 hectares and depth in its middle part between 8 and 10 meters. Floristic research have been carried out in the period between 2007 and 2010. The lake itself and the narrow lake shore parts are characterized by rich flora and vegetation. 175 species of vascular flora within 52 families and 126 orders were recorded. This research covered taxonomic, ecological and phytogeograpic anaysis (Tables 1, 2, 3). Taxonomic analysis shows that there are 3 Pteridophyta species (1,71%), 130 Magnoliopsida species (74,85%) and 42 Liliopsida species (24%) (Table 1). The analysis of life forms shows that the most frequent one is hemicryptophytes with 94 species (54%), then hydrophytes with 28 species (16%) (Table 2). The phytogeographlc analysis is dominated by plants of Euroasian floral elements with 60 species (34,28%) and widespread plants with 60 species (34,28%) (Table 3). The research of water and marshland vegetation shows that associations apper in 3 vegetational classes, 7 orders, 7 alliances and 11 associations (As. Lemno - Spirodeletum polyrrhizae W. Koch 1954, As. Lemnetum trisulcae Knapp et Stoffers 1962, As. Lemno – Utricularietum vulgaris Soó 1947, As. Myriophyllo - Nupharetum W. Koch 1926, As. Phragmitetum australis Soó 1927, As. Scirpetum lacustris Schmale 1939, As. Typhetum latifoliae G. Lang 1973, As. Typhetum angustifoliae Pignatti 1953, As. Caricetum ripariae Knapp et Stoffers 1962, As. Glycerietum fluitantis Eggler 1933, As. Oenantho aquaticae – Rorippetum amphibiae Lohm. 1950). Results of this research contribute to knowledge on flora and vegetation in the area of
Sovsko lake and protection of natural heritage.
