  • 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 area consists of the deltas of several watercourses ( Čierna Orava, Kriváň and Hraničný Kriváň) passing through the coves interconnected by the water surface - The Oravská vodná nádrž. It was artificially built and completed in 1953. The coastal parts of the area are inhabited by biotopes of submerged and floating vascular plants and surrounded by forests protection belt. Some forest parts of the area, such as the Murgaše and Osadská, were formed on the peat bog substrate. The water level in the reservoir varies depending on the operation mode of the water dam work.

4.2 Quality and importance

The communities of eutrophic to mesotrophic stagnant water in the coastal parts of the bay, surrounded by floodplain forests with enclaves of forest peat bogs.
