Other Site Characteristics

The site is the biggest and oldest bog in Croatia. It is situated in Banovina area, depopulated since last war in Croatia. In the past, this site was used by local people for agriculture. However, since war and depopulation of this area vegetation succession is visible. Site is protected as a special botanical reserve. According to recent research, it represents the mosaic of different associations. Interesting feature of this bog are potential elements of ombotrophy, in Croatia known only from Trstenik in Gorski Kotar. Site hosts well preserved associations Drosero-Caricetum stellulate and the last preserved association of Rhynchosporetum albae in Croatia. Site also hosts the biggest area covered with association Caricetum lasiocarpae, in Croatia known only from small locality within the Plitvice Lakes National Park and Sunđerac in middle Velebit. The site is an area with the richest Sphagnum flora in Croatia and represents the center of diversity of this genus in Croatia. Until now, eight species of Sphagnum have been recorded here. Litostratigraphic units represented in this area are neogene clastic sediments (sands and gravels with layers of clay)-Pl,Q. South and west side of the bog are surrounded by Oštri vrh and Sablić brdo mounds. Two streams flow near the bog. Presence of fluvial process. Dominant soils are pseudogley-gley partially hydroameliorated and pseudogley.

4.2 Quality and importance

- one of only two sites in Croatia for habitat type 7150 Depressions on peat substrates of the Rhynchosporion and one of only three sites with Rhynchospora alba - one of only two sites in Croatia for 7110*; this habitat type occures in a complex with 7140 where individual ombotrophic Sphagnum tofts are represented locally - largest peat bog in Croatia with rare and threatened species - center of sphagna diversity in Croatia - largest number of different sphagna are present - one of only three localities with Caricetum lasiocarpae
