Sažetak
The Sopot waterfall is the biggest waterfall in the Nature park Žumberak - Samoborsko gorje, situated about 3 km NW from the village Sošice. So far, there were no methodical investigations of flora or vegetation in the area around the Sopot waterfall and along the upper flow of the brook Kupčina. The initial research was carried out in the summer and autumn of the year 2009 and in the spring and early summer of the year 2010. Plant species found on the research area were recorded during every field trip and the herbarium samples were taken for later identification of some plant taxa.
For better recommendations how to protect different habitats the study area was divided into 3 subareas; subarea 1 - the waterfall area, subarea 2 – the area of the brook Kupčina, which flows through small canyon and subarea 3 – the area of upper flow of the brook Kupcina, located in small dale, where few water streams appear and form more or less unitary stream of the brook Kupcina. In our preliminary study we recorded in total 204 plant species, out of which according to IUCN categorization, two critically endangered (CR): Eriophorum angustifolium Honck. and Tofieldia calyculata (L.) Wahlenb., one endangered (EN): Eriophorum latifolium Hoppe, one near threatened (NT): Cephalanthera damasonium (Mill.) Druce and four vulnerable (VU): Carex panicea L., Helleborus niger L. subsp. macranthus (Freyn) Schiffner, Ophrys fuciflora Haller and Ophrys insectifera L. In the researched area 44 species were protected and 15 strictly protected by the Croatian law.
The research showed that subarea 1 has a different type of habitat than subareas 2 and 3. The subarea 1 is covered with beech and hop hornbeam forest (Ostryo-Fagetum M. Wraber ex Trinajstic 1972) and we assume that it should be left to spontaneous natural development, because it does not show any signs of endangerments.
On the subareas 2 and 3 we recorded two endangered habitats: elements of flat, basophilous, rich fen with bog cotton (Eriophoro-Caricetum paniceae Horvat 1964) and (semi)dry continental grasslands from Festuco-Brometea Br.-Bl. et R. Tx. 1943 (as. Seslerietum kalnikensis Horvat 1942) class, which are the habitats rich with many significant species of open habitats, especially with orchids. Both habitats are endangered by overgrowing and lack of extensive pasture and they are in advanced stage of succession towards wood associations, why we consider that it is necessary to try to stop the succession in progress. At first it would be necessary to remove the woody vegetation which endangers the rich fen and grassland vegetation beside the brook, and later on, it is important to periodically organize mowing or intensive pasture in that area.
