  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

Other Site Characteristics

The Trstenik bog is located in a karst depression at the foot of Trstenik Peak (1240 metres above sea level) in the Obruč mountain-cluster. Located 3.5 kilometres northwest of Obruč Peak, the bog lies at about 960 metres above sea level in the vegetational zone of beech and fir forests (Abieti-Fagetum). It has an elongated oval shape and is about 500 metres wide and 250 metres long. The part of the bog overgrown with bog vegetation is several hectares in size. On the southeast side of the bog is a spring that never runs dry. The Trstenik bog is important as one of the largest bogs in Croatia and a unique remnant of raised bogs. In Croatia, bogs are very rare as they are at the edge of their distribution range and represent relics located in sites with specific microclimate conditions. This is the only site of blanket bog in Croatia, distributed on the very edge of blanket bog habitat type range. This is also the only site in Croatia with characteristic species of blanket bogs Eryophorum vaginatum. Lithostratigraphic unit represented in this area is alluvial sediments (b-aQ2). Soil is rendzina on gravel.

4.2 Quality and importance

- one of only two sites in Croatia for 7110* - very important site for som rare sphagna and rare and threatened species on national level
