Sažetak
This study presents the results of floristic research of the flat fen along a part of the Jarak stream in the Nature Park Žumberak-Samoborsko gorje. This fen belongs to order Caricetalia davallianae Br.-Bl. 1949, alliance Caricio davallianae Klika 1934, association Eriophoro latifolio-Caricetum panicae HT ex Trinajstić. The area was researched in 2007/2008 and it was divided into four subareas: fen and 3 succession stages, Phragmites subarea, transitional stage between common reed (Phragmites australis) and young forest, and young forest. During the winter period of the research the vegetation on 3 subareas was cut and the following year floristic changes were monitored. Recorded plants were taxonomically analyzed and ecological indicatory values calculated according to Landolt. During this study 222 plant species were found, out of which 14 endangered (according to IUCN categorization) and 58 protected or strictly protected in Croatia. Ecological values according to Landolt showed only minor differences between the subareas, out of which only the young forest subarea stood out. The removal of the plants resulted with low floristic changes, present mostly on the young forest subarea, where species of open habitats enlarged their abundance, but no characteristic fen species were recorded. It is concluded that the fen along the stream Jarak should be protected, because of its rare vegetation type, but also because of endangered and protected species found in this area. It is also necessary to carry out regular removal of woody vegetation from all the subareas and multiple mowing during the first two or three years to protect the fen and even enlarge its surface.
